1.0 Background

The Government of the Republic of Mozambique (GOM) has received a grant from the Millennium Challenge Corporation (MCC), an innovative United States established foreign assistance program designed to reduce poverty by promoting sustainable economic growth. MCC operates on the principle that aid is most effective in countries that promote good governance, economic freedom and investments in people. The GOM, through MCA (Millennium Challenge Account-Mozambique, a public institution created by the GOM) and its National Directorate of Water (DNA-GOH) organ, intends to use a portion of the proceeds of this grant, to carry out feasibility studies relating to the rehabilitation and augmentation of the Nacala Dam and Reservoir.

National Context Situated on the Indian Ocean coast of southern Africa, Mozambique is the 16th largest country in Africa in geographical and regional terms. It borders South Africa and Swaziland in the south, Zimbabwe and Zambia in the west, and Malawi and Tanzania in the north. It has 799,380 km2 and over 2,750 kilometers of coastline. Mozambique’s total population is just over 19 million, nearly 70% of which is living in rural areas. Despite a growing trend of urbanization, Mozambique remains one of the less densely populated nations in Africa, with 24.3 inhabitants per km2. The topography is dominated by flat rolling areas along the coast and further inland. There are several very large rivers such as the Zambezi, the Limpopo and the Save which are surrounded by wide sedimentary valleys. Near the coast the Limpopo and Zambezi rivers form deltas, subject to seasonal flooding. Other rivers form estuaries with widespread swamp-land. The western parts of the country are hilly, with the highest mountains rising to nearly 2,500 m. The predominant soils are fine grained, generally sands and silts, although clays are found in the river valleys. In areas where the landscape is more rolling the finer soils can be interspersed with coarser materials such as gravel. The country lies in the region affected by the monsoon and receives most of its rainfall between October and April. The annual precipitation differs between localities. In high-lying areas of Zambezia Province the maximum annual rainfall is more than 3000 mm, while in the south of the country the minimum is about 450 mm. The wettest month is January with an average rainfall of 130 mm; the driest month is July averaging only 13 mm. Temperatures follow a similar pattern. The extremes occur in February and July with average daily temperatures of between 22-31 °C and 13-24 °C, respectively.

The country has great economic potential in agriculture, tourism, fishing and mining, which has largely been untapped due in part to the prolonged period of civil conflict. Mozambique’s economy is largely agricultural in nature: shrimp, prawns, cotton, cashew nuts, sugar cane, and copra make up 45% of the nation’s GDP (which has grown in recent years at an annual rate of roughly 8% (1996-2007 average). Subsistence farmers produce cassava, corn, and rice. The Mozambican industrial sector fell to a near stand-still due to the civil war. Encouraging economic growth in this sector is a Mozambican priority. Tourism is another sector with great development potential. Prior to independence from Portugal, Mozambique was one


of 81

of southern Africa’s most popular tourist destinations, hosting millions of foreign travelers who enjoyed Mozambique’s unspoiled beaches and offshore islands. The industry was crippled by the civil war, but is slowly growing again.

Despite Mozambique’s rapid economic growth, half of the Mozambican population still lives in poverty. The Government’s Action Plans for Poverty Reduction – PARPA’s - are based on the premise that broad-based economic growth and infrastructure investments are critical to poverty reduction. In the PARPA, the Government outlines investment in human capital, including water and sanitation services, as one of the three pillars to meet a sustained growth agenda.

As a direct response to PARPA, the Millennium Challenge Corporation (MCC) and the Government of Mozambique (GoM)’s Compact (Signed July 13, 2007) defines Water and Sanitation (WSS) investments in eight cities of three northern Mozambique provinces – Cabo Delgado, Nampula and Zambézia. Among the projects identified by the GOM is the “Nacala Dam and Reservoir.” The Government of Mozambique’s plans are to use MCC funding to rehabilitate and/or augment the capacity of the Nacala Dam and Reservoir.

The Nacala Reservoir is the primary water supply for the City of Nacala, also to receive funding for water and sanitation system improvements. Due to a previously identified risk of dam failure, water levels at the dam are reported to be kept low, reducing the water supply for Nacala significantly. In addition, there are significant increases projected for water demands for the city due to population growth and other planned developments. Projected demands for urban growth in the City of Nacala greatly exceed the existing water supply capacity of the Nacala Dam Reservoir. The Implementing Entity Under the Implementing Entity Agreement between the Government of Mozambique’s MCA (MCA) and National Directorate of Water / Cabinet of Hydraulic Works (DNA-GOH), DNA will transfer the Nacala Dam operational responsibility to the Regional Water Authority-Central North (ARA-Centro Norte) which has legal standing but is not yet operational. Due to the combined implementation and operational responsibilities, the Implementing Entity is referred to as DNA-GOH/ARA-CN.1

The MCA Management Unit (MCA MU) includes Water and Sanitation Program Manager that will be responsible for coordination with DNA-GOH and other Implementing Entities responsible for water and sanitation projects. The primary point of contact in the MCA MU will be the MCA Nacala Dam Coordinator specifically dedicated to the MCA projects that are implemented by DNA-GOH. The Nacala Dam Coordinator will be involved in all interactions between DNA-GOH and the members of the MCA MU including the Procurement Manager and the MCA ESI Specialist. The MCA Nacala Dam Coordinator will be responsible for provision of key reports and documentation needed by DNA-GOH for implementation, ongoing monitoring

of performance of DNA-GOH responsibilities described in the Implementation Agreement, timely review and coordination on all elements of the Compact Agreement Work Plan, as well as coordination with MCA on all milestones where “no objection” is required. MCA is the Accountable Entity and is responsible for providing the financial resources for the water supply projects described in the Compact. MCA shall make available to DNA-GOH resources required to provide proper oversight of these activities – including the resources required to staff a Dedicated Team within DNA-GOH. DNA-GOH shall use its own resources and the resources of the MCA dedicated project coordinator to implement the projects related to the rehabilitation of the Nacala Dam and institutional development as set forth in the Compact and a detailed work plan developed by DNA-GOH. DNA-GOH is responsible to oversee the implementation of the projects in a timely and cost effective manner. MCA shall be responsible to (i) review DNA-GOH implementation progress, (ii) facilitate the required approvals, (iii) contract for resources associated with the studies, consultants, goods, services and works, and (iv) maintain donor relations. Nacala Dam Project Implementation Structure

As the implementing entity, DNA-GOH will have overall project implementation responsibilities. DNA-GOH will be required to coordinate with the MCA Management Unit (MCA MU) to ensure project activities are carried out in a timely manner consistent to project design and implementation work plans. DNA-GOH will work closely with the MCA Nacala Dam Coordinator, and DNA will supervise the DNA Nacala Dam Coordinator, who will be based within DNA-GOH. As the implementing entity, DNA-GOH shall have the following key functions related to rehabilitation work for the Nacala Dam. DNA-GOH will be responsible specifically for the following:

• Implement rehabilitation and rising of the Nacala Dam, and reservoir and associated environmental and resettlement work.

• Manage the Project’s schedule and budget. Monitor and report on the physical and financial progress of the works undertaken by all consultants and contractors on quality of goods, works, and services supplied.

• Manage institutional activities related to public outreach and coordination with existing and new organizations involved in the water supply for Nacala such as the current Empresa de Aguas de Nacala (EAN), the planned Provincial Water Board and the planned Asset Management Unit as well as any future private operators. This responsibility includes drafting and coordinating the approval process for any required legal documents.

• Supervise the Project-Dedicated Team, consisting of the Nacala Dam Coordinator, Hydrologist and the Hydraulic Engineer Technician. Though these positions are funded through MCA-Mozambique by the Compact, staff supervision and the review of the staff’s work will be the responsibility of DNA-GOH.

• Ensure quality through the implementation of a Quality Assurance Plan (QAP) or Plans for all aspects of the project including procurement support, feasibility, design, construction, operation and project closure. The QAP(s) should indicate who is responsible for review and what actions are to be taken in response to problems.

• Perform key financial management and procurement activities by preparing draft RfPs, EOIs, SOWs, TORs, for use by the MCA Procurement Agent and reviewing and approving invoices.

Environmental, Legal, Regulatory and Institutional Context The Government of Mozambique (GOM) envisions that the use of natural resources fulfills the basic needs of the people and development of the nation in equilibrium with economic growth, technology development, environmental protection and social equity. DNA-GOH will be responsible for ensuring that all activities of the Project are implemented in a manner consistent with MCC’s Environmental Guidelines and


of 81

applicable Mozambican environmental laws and regulations. DNA-GOH will also have responsibility for overseeing the implementation of Environmental Management Plans (EMPs) for all activities in the Project and verifying that the Works contractors are implementing relevant mitigation measures as defined in and required by the EMPs. All activities should be carried out in close coordination with the MCA Environment and Social Impact Specialist (MCA ESI Specialist). Under Mozambican law, no project may be undertaken without a license issued by the Ministry for Coordination of Environmental Activity (MICOA). As defined in MICOA’s directives and ministerial diplomas, key steps in the environmental licensing process are:

• A pre-assessment determination by MICOA of project environmental category and the subsequent procedures that must be followed;

• Establishment of a Technical Assessment Commission, composed of specialists from within and outside MICOA to review environmental impact assessments and related documentation;

• Public consultation in accordance with MICOA’s Ministerial Diploma 130/2006; and

• Review of the environmental report by the Technical Assessment Commission and decision on the license and any attached terms and conditions.

There are no requirements within the GoM regulatory framework for an assessment of public health and safety impacts to be included in Environmental Impact Reports. However, given the importance of the these issues, the Consultant will include Health and Safety Impact Statements in Environmental and Social Assessment Reports, based upon standards set by the MCC Environmental Guidelines and the World Bank Environment Handbook.

Resettlement and Social Impact Management DNA-GOH will be responsible for management of all resettlement activities associated with the Project. These will require management of both, the development and implementation of Resettlement Action Plans and may involve procurement and financial management assistance related to appropriate professional services. All activities should be carried out in close coordination with the MCA ESI Specialist as follows. Specifically, DNA-GOH will be responsible for ensuring that construction timelines have adequate time for RAPs, that Right of Ways are completely clear before authorizing construction for any given project element, and for proper disbursement of resettlement funds to affected parties in the project area.

2.0 Description of the Consultancy

Concurrent to the works associated with the Nacala Dam and Reservoir described in this document, the MCA will be tendering contracts for the feasibility study, design, and construction of the rehabilitation and expansion of the water supply system for the City of Nacala. These two projects are closely related and will require close coordination. The division of responsibility between the Nacala Dam and Reservoir Project and the Nacala City Water Supply Project lies at the reservoir outlet tower. All civil engineering aspects relating to the rehabilitation and raising of the reservoir outlet tower are the responsibility of the Nacala Dam consultant. The Nacala City Water Supply Project is responsible for the pumps and pipeline from the tower to the adjacent water treatment works. The Nacala Dam consultant shall provide all necessary assistance to the consultant engaged on the water supply project to enable him to fully design these aspects of the scheme. Therefore, the Consultant is required to liaise with the Team conducting the associated feasibility studies for the City of Nacala water supply system.

The projected water demand of Nacala City and surrounds indicates that the capacity of the Nacala Dam will have to be increased. The GoM proposed that this be done by raising the dam and potentially constructing an additional dam on the nearby Sanhute River from where water would be piped to the Nacala Dam where a treatment works is located.

This study was preceded by a pre-feasibility level study into Nacala Dam and a new dam and transfer scheme to augment the supply to Nacala. The results of this investigation are included in the report “Nacala Dam and Reservoir, Revised Technical Review and Interim Report 1, Mozambique Water & Sanitation Project, October 2006”, hereafter referred to as the Baker Report. The main recommendations of the study are that Nacala Dam has to be rehabilitated and raised and that a new dam may be required on the Sanhute River (to be located approximately 9 km south west of Nacala Dam). This TOR focuses on the rehabilitation and raising of Nacala Dam only as Sanhute Dam will be addressed separately.

The Consultancy for the Nacala Dam and Reservoir Project includes the following work aspects:

• Engineering feasibility study to assess the viability of rehabilitating and raising Nacala Dam while maintaining water supplies to Nacala City.

• Topographic survey of the Nacala Dam site, surveyed to 1 m contour intervals, and of the reservoir area, to 5 m contour intervals.

• Bathymetric (hydrographic) survey of the Nacala Dam reservoir.

• Geotechnical investigation. The purpose of the geotechnical investigation is to provide input and information for the rehabilitation and rising of Nacala Dam. Estimates of available construction material quantity and quality are also to be provided.


of 81

• Environmental Impact Assessment (EIA) study and related licensing requirements. The findings and mitigation requirements from this study need to be incorporated into the dam design so as to minimize the effect that dam construction might have on the natural environment and the population of the surrounding area. To ensure sustainability of the water resource and reservoir the study should also make recommendations on appropriate management in the watershed upstream of the dam.

• Development and support of the implementation of a Resettlement Action Plan consistent with the World Bank Policy on Involuntary Resettlement (O.P. 4.12)

• Detailed Design, including the preparation of technical inputs to tender documentation. Provision of advice during the procurement process.

• Supervision of construction

In terms of the EIA, an initial impact review has been conducted on the proposed raising of Nacala Dam. Potential environmental and social impact issues were identified taking into account the initial technical assessment. However, a full EIA is required for the proposed activity, a large dam investment project that falls into Category “A” Projects as stated by the Mozambican Environmental Impact Assessment Regulation and MCC Environmental Guidelines. Requirements for environmental releases from the reservoir should be evaluated as part of the integrated design and EIA process.

2.1 Nacala Dam and Reservoir

The study area includes one site, namely the Nacala Dam.

Nacala Dam is located on the Muecula River approximately 30 km south west of Nacala City. Nacala Dam is the principle source of water to the City and is of strategic importance to its development. The national N13 Nampula / Nacala road crosses Nacala Dam and is therefore an important consideration in rehabilitation of the dam as a road deviation would impact traffic. Environmental and social/resettlement considerations are discussed in Sections 4.5 and 4.7.

The port of Nacala is the maritime end of the important Nacala/Malawi corridor, and is one of the three most important ports in Mozambique. The present population of Nacala is approximately 300,000 and the current growth rate is estimated at 6%. Nacala is an important economic center of the northern region of Mozambique.

The design of Nacala Reservoir was commissioned in 1969 and the construction works were completed in 1974. The reservoir embankment is 17.4 m high and 324 m long and has a spillway comprising two 6 m wide radial gates situated on the left flank. The dam embankment is not equipped with an outlet works and has a full supply level of 74 meters above sea level (masl). Raw water is abstracted from Nacala Dam via an intake tower situated approximately 55 m upstream of the spillway inside the dam basin. Water is pumped from inside the tower to a water treatment works situated against the higher left flank of Nacala Dam. From the treatment


of 81

works water is conveyed to Nacala City at a rate of approximately 300 m3/h. The live storage of the reservoir is 3.5 million m3 (mcm).

In 1982, due to malfunction of the radial gates, Nacala Dam was overtopped for 10 consecutive hours. The roadway gravel and the downstream shoulder were scoured away to a considerable depth for a distance of between 80 m and 100 m from the spillway towards the right flank. In 1983 the dam was rehabilitated with support of Dutch funds. In 2004 a site inspection was undertaken, at which time it was concluded that the dam had a number of deficiencies and the risk of dam failure was very high. It was also reported that prior to the 1982 flood event, the dam embankment did not leak.

Drought conditions are recurrent in Nampula Province and in 2004 the magnitude of the drought was such that the Nacala Reservoir was drawn down to below the minimum supply level, impacting water supply to Nacala City.

Minimal as-built documentation is available with respect to Nacala Dam. The spillway gates for Nacala Dam are in a state of disrepair. The upstream face of the dam is protected by hand-packed rip-rap, while the downstream face of the dam is protected by means of grouted stone pitching, placed between regularly spaced concrete storm water chutes running down the slope.

In 2006 Baker reports that the dam is operated sub-optimally because extensive seepage occurs when the water level rises to within about 4 meters of the dam crest, which corresponds to the embankment repair zone after the 1982 floods. When the reservoir water level reaches a level of 4 m below the embankment crest, leakage through the top of the embankment commences, but the leakage water is clear and not turbid. Above this level, while the leakage water remains clear, the spillway radial gates are not opened. If the leakage water turns turbid (dirty), then the spillway gates are opened, Nacala Water is informed and Nacala Water informs DNA-GOH Maputo. When the water level rises to within 3.5 m of the dam crest, the spillway gates are opened. A subsequent site visit and discussion with Nacala Water in 2007 indicates that perhaps the seriousness of the leakage at the dam site is overstated by Baker.

The recommendations of the pre-feasibility study mentioned above concluded that Nacala Dam has a high failure risk due to the following:

• The embankment was repaired after being overtopped with a permeable gravel zone increasing the risk of piping failure. Seepage through the embankment occurs when the water level rises to within about 4 meters of the dam crest. For this reason the dam is operated sub-optimally.

• No internal drainage system has been provided which is of concern as the soils were found to be potentially dispersive. This also increases the failure risk due to piping.

• The existing gated spillway is in a state of disrepair and the spillway capacity is inadequate thus increasing the risk of overtopping and potential failure due to embankment scouring.


of 81

• The dam has operational inefficiencies and opening of the radial gates when required, can not be guaranteed.

In addition to the above, Nacala Dam embankment is not equipped with a separate outlet works to allow environmental flow releases.

Nacala Dam yields the cheapest water of all sources considered in the pre-feasibility study and it is therefore recommended that Nacala Dam Full Supply Level (FSL) be raised by 2 m.

3.0 Objectives and Outcomes of the Consultancy

The overall objectives of the study are to prepare the following:

• Method and detail to rehabilitate Nacala Dam and to raise the full supply level by 2 m that results in minimal disruption to the water supply for the City of Nacala over the life of the project.

• A sound and robust Environmental Impact Evaluation process, (known as the Avaliação de Impacto Ambiental (AIA)), that covers all relevant direct, indirect, induced and cumulative environmental and social impacts associated with the proposed project focusing, in particular, on impacts arising from raising the Nacala Dam wall and the temporary and/or permanent deviation of the N13 highway across the Nacala Dam wall and sustainable operation. The AIA is the entire set of procedures from the submission of initial information about the proposed activity for pre-assessment, to the preparation of the EIA and EMP, through to the issuing of an environmental license. The Consultant is required to prepare each of the procedures in the AIA, as described in Section 5 below and based on the guidelines provided in the Decree Number 45/2004 and General Directive Number 129/2006 of the GoM, Legal Framework for Environmental Licensing in Mozambique.

• Specific objectives in support of the overall objectives include, but are not limited to, the following:

• Undertake geotechnical and field observations at the Nacala Dam site;

• Provide adequate topographical information in order to perform the design for Nacala Dam rehabilitation, raising and EN13 road relocation;

• Design an appropriate system for raising the main dam embankment. This may require the construction of a temporary diversion road;

• Design, if required, a fish way structure;

• Design outlet works arrangements;

• Design spillway arrangements;

• Develop and support the implementation of a Resettlement Action Plan.


of 81

• Prepare tender documentation and advice throughout the Contractor procurement period. Note that “Contractor” refers to the entity that builds the Dam; and

• Supervise the construction works.

4.0 Scope of Services

4.1 General In order to achieve the objectives of the Consultancy, the Consultant must supplement the following activities as necessary at the time of this solicitation based upon information available at the time of bid preparation.

In designing the structures the Consultant will be required to liaise closely with MCA, who will have to approve the designs. All designs have to be according to internationally acceptable practices. Environmental and social requirements are very important and designs have to be adopted to incorporate these requirements where ever possible.

In the feasibility stage the Consultant shall develop preliminary design layouts to a level of detail which will show the principal components and allow quantities to be taken off / estimated. The Consultant shall identify and present alternative layouts and identify from them the least cost solution to meet all requirements for implementation and operation except where indicated otherwise by the client.

The Consultant alone is responsible for the sufficiency of his/her work and these TOR are not intended to be an exhaustive list of all activities, but to indicate the level of work required for the outputs. Although the work covers various specifics studies/surveys, the Consultant shall ensure that it forms a holistic, integrated study resulting in sustainable outputs.

The Client reserves the right to designate an observer(s) from interested stakeholder communities such as agencies of the Mozambican government working in the local area. The designated observer(s) may accompany the Consultant on field surveys and introduce the Consultant to local communities and leaders. However, the designated observer(s) is not authorized to make any decisions on behalf of the Client or otherwise influence the work of the Consultant.

To facilitate participation by the Client or designated observer(s) in field surveys, the Consultant will provide the Client with prior notice of intent to conduct field surveys. Such notice will be provided no less than 15 days before such field survey is scheduled to take place.

Iterative design should be adopted for all schemes. Following proper environmental and social scoping but before detailed EIA, iterative design of the proposals must be worked out by the Consultant’s engineering and environmental staff – with input from the Client as appropriate. In this way adverse impacts are designed out as far as possible rather than leaving them to be mitigated at a later stage.


of 81

In order for the scheme to proceed to eventual construction it is necessary to obtain an environmental license from the Ministry for Coordination of Environmental Affairs (MICOA). The Consultant is responsible for ensuring that the Client is provided with all necessary documents for submission to MICOA to expedite receipt of approvals, and that stakeholder consultation is carried out in accordance with the current legislation covering environmental permitting.

It is anticipated that the tasks described in the following sections will be required at a minimum.

4.2 Geotechnical Investigations 4.2.1 Objectives of the Required Services The services of a Consultant is required to carry out such geotechnical and field investigations and design studies as are necessary to complete the works outlined below.

• Investigate the feasibility and methodology of rehabilitating and raising the Nacala Dam Full Supply Level by 2 m. with minimal disruption to the water supply for the City of Nacala;

• Establish the extent and nature of the leak in the Nacala embankment and provide a design for its repair;

• Determine the road subgrade conditions and temporary founding conditions for the road pavement and river crossing to be constructed as a temporary detour of the N13 downstream of Nacala Dam while it is being repaired and raised; and

• Locate material suitable for the construction of the Nacala Dam raising works.

4.2.2 Embankment Raising and Rehabilitation The Consultant is required to carry out the following works:

• Review all previous studies and designs carried out at the Nacala Dam;

• Investigate geological and ground water conditions and propose methods of treatment to ensure that the stability and permeability of the area downstream is not adversely affected by the water in the reservoir;

• Evaluate and verify that the foundation of the intake tower, proposed spillway locations, stilling basin, outlet works, and fish ladders as may be required are able to with stand any required improvements and modifications associated with the raising of the dam;

• Undertake a detailed geotechnical investigation to ascertain the engineering properties, and their variability, of the core and shoulder materials of which the embankment is constructed. This is to entail drilling nine boreholes employing rotary core drilling techniques. Three boreholes are to be drilled through the core material and three each


of 81

through the upstream and downstream shoulders. Each borehole is to be drilled to at least 1 meter into the underlying bedrock. Cognizance is to be taken during the drilling and other works that a major access road, namely N13, crosses the dam and disruption to traffic flow is to be minimized as far as possible;

• Standard Penetration Tests (SPT) are to be conducted within the boreholes at 1.5 m depth intervals, and at least three undisturbed tube samples (Shelby tubes or U100 where appropriate) are to be taken of representative core and shoulder material from each borehole near the top, at the center and near the base of the embankment. The samples are to be thoroughly sealed to prevent evaporation and appropriately labeled;

• Every effort should be made to recover 100 percent of drilled material employing triple tube coring technology. The drilled core and SPT samples are to be appropriately labeled, sealed in plastic and stored in a labeled and robust purpose made core box of wood or metal construction;

• The core should be photographed and logged by an experienced engineering geologist or geotechnical engineer employing the methods and procedures prescribed in the document Guidelines for Soil and Rock Logging in South Africa (1990), prepared by the Geotechnical Division of the South African Institute of Civil Engineers and the Association of Engineering Geologist of South Africa, or approved equal;

• Upon completion of the drilling works Casagrande type standpipe piezometers manufactured of porous ceramic and attached to a 25 mm PVC pipe are to be inserted into each of the boreholes drilled in the embankment core and shoulders. Each piezometer is to be encased in clean sand over a height of at least 1 m above the tip and isolated from each other with bentonite. The top of the hole is to be sealed off with a sand cement grout mix and the piezometers are to be protected from damage and vandalism by enclosing them in a steel pipe cast in concrete at the surface and provided with a lockable cap. These instruments shall be read by the Consultant from installation up to the start of construction to obtain information on the performance of the embankment for the studies and designs;

• Laboratory tests are to be carried out on the soil samples recovered from the boreholes and are to include, as a minimum:

- Foundation indicator tests comprising Atterberg limits determinations, sieve and hydrometer analysis and linear shrinkage tests;

- Tests for dispersivity including Exchangable Sodium Percentage (ESP), crumb test, double hydrometer and pinhole test;

- Shear strength tests comprising consolidated undrained triaxial tests with measurements of pore water pressures, consolidated drained


of 81

shear box tests and unconsolidated undrained triaxial tests; and

- Saturated consolidometer tests.

Possible variations in the consistency of the embankment material is to be assessed by carrying out Dynamic Probe Super Heavy (DPSH) tests on and around the crest and downstream and upstream of the embankment.

4.2.3 Locating Leaking Zone Based on pre-feasibility studies, preliminary indications suggest that leakage of the embankment is a result of the breached wall having been repaired with permeable gravel. It is important that the Consultant accurately establishes the lateral and vertical extent of the zone in which repairs to the breached section of the embankment were carried out. To this end the Consultant shall:

• Excavate test pits on the upstream and downstream shoulders employing hand labor. In an attempt to establish the lateral extent of the repaired section the holes shall initially be at 20 m centers in the suspected zone and 50 m in the remaining part along the length of the wall and upstream and downstream of it, with intermittent holes being excavated where considered necessary. The pits are to be supported over their full depth to ensure sidewall stability from adjacent traffic loads;

• The pits are to be profiled over their full depth by an engineering geologist or geotechnical engineer as prescribed in the document Guidelines for Soil and Rock Logging in South Africa (1990), prepared by the Geotechnical Division of the South African Institute of Civil Engineers and the Association of Engineering Geologist of South Africa;

• After completing the excavation and sampling the tests pits they are to be backfilled with the excavated material and compacted in 150 mm thick layers with hand stampers or a Waker compactor; and

• Rates of seepage into the ground will also be assessed in view of the sandy soils in the area surrounding the dam. The assessment will establish seepage rates within the existing reservoir and in the zone to be inundated by the raised reservoir elevation to ensure adequate knowledge of water balance in the reservoir after construction.

4.2.4 Temporary Detour Road The Consultant is to undertake a centerline survey along the proposed detour road to be located around and downstream of the Nacala Dam. The Consultant will consider various alignments for routing the detour road, taking into account potential impacts to surrounding communities. The Consultant should propose a routing option that minimizes physical and economic disruption to surrounding communities and eliminates the need, as much as possible, for relocating any physical structures, including houses and community infrastructure. This road is to be constructed while the dam repair and raising works are being undertaken. The survey should comprise the excavation of test pits at least 150 m centers employing an excavator. In addition, and if rock is not encountered within the depth of the test pits at the position of the


of 81

culvert or bridge crossing, a borehole is to be drilled on either side of the river at the proposed foundations. Drilling is to be carried out as described in Section 4.2.2 above. The borehole core and test pits are to be logged and profiled as previously described and large bulk samples are to be recovered from the test pits at selected locations to establish the suitability of the material for use as subgrade for road layer works design. Such tests should include, among others:

• Road indicators comprising Atterberg limit determination, sieve analysis and linear shrinkage tests; and

• Modified AASHTO compaction and California Bearing Ratio (CBR) tests.

4.2.5 Borrow Pit Investigation The Consultant shall carry out a borrow pit and other investigation including the location, excavation, profiling, sampling and testing to obtain material in sufficient quantities and suitable for use as:

• Low permeable soil for replacing the material that has been used to repair the embankment;

• A graded filter for placement in a chimney and blanket drain;

• Upstream and downstream shoulder material;

• Rocks for dam slope protection;

• Aggregates for concrete, and;

• Sub-base and base course in the temporary road pavement of the detour route.

Consideration should be given to stabilizing some of these materials with cement, in which case Unconfined Compression Strength (UCS) tests should be carried out on the stabilized specimens. The Consultant shall also investigate and identify the owners of and those who have access rights to the land where the materials and potential borrow pits are located. This information should be included in the resettlement scoping section of the EIA (see Section 4.6 below).

4.3 Topographic Survey 4.3.1 Objectives of the Required Services The overall objective of the survey is to provide adequate topographical information in order to perform an EIA and a feasibility and detailed design for Nacala Dam rehabilitation, raising and N13 road relocation.

4.3.2 General Topographical surveys of the Nacala Dam site are required. These include:

• Tachometric survey of the Nacala Dam embankment extending at least 100m beyond the embankment in all directions. Mapping should be produced at 1 m contour intervals;


of 81

• Detailed survey including coordinates of the existing structure, regular sections of the dam and dam crest and weak or deformed zones on the dam slope and downstream toe including identification and the extent of significant features on the survey.

• Aerial photography or GPS survey shall be used to survey the reservoir extent taking into account a 2m raising of the dam Full Supply Level. This survey needs also to extend downstream of the Nacala Dam to include all possible road diversion routes. Subject to confirmation in the Feasibility Study a distance of 2 km downstream of the dam is recommended. Mapping should be produced at 5 m contour intervals. A Lidar-based topographic survey will also be considered as an alternative to the aerial topographic survey; and

• A bathymetric survey of the existing reservoir will be conducted to re-establish the volume-depth and area-depth relationships which have been altered in the 30-years since the dam was constructed. The combined topographic and bathymetric surveys would provide a basis for establishing post-construction reservoir rating curves, for estimating sedimentation rates, for estimating water budget components such as evaporation and seepage losses, and for establishing reservoir operation rules.

4.3.3 Aerial Photography (i) General The aerial photography shall include the supply of the processed negative film, two sets of contact prints, one set of diapositives and the flight plan. Alternatively digital images may be provided in place of the negatives, diapositives and contact prints. The scale of the photography will be 1:10 000. All surveys shall adopt the same designated vertical control datum

(ii) Aerial Photography Maps and GPS Survey Plotting All topographical features and man made structures shall be plotted.

Contours shall be plotted at 5 m vertical intervals and supplemented by spot heights wherever the contours are insufficient to portray ground shapes accurately. A DTM will be surveyed covering the specified area in a 40 m grid with break lines.

The accuracy of the DTM points from the aerial photography shall be within 0.5 m vertically and 0.3 m horizontally.

The accuracy of the DTM points from GPS shall be within 0.03 m vertically and 0.03 m horizontally.

(iii) Tachometric Survey The tachometric survey will be on the WGS 84 UTM survey system. The DTM survey of the existing dam embankment and surrounds will be done in such a way as to cover the entire survey area in a 20 m grid. The survey has to cover an area of at least


of 81

a 100 m beyond the embankment in all directions. The accuracy of the DTM points shall be within 0.03 m vertically and 0.03 m horizontally. Contours shall be generated at 1 m vertical intervals. The survey of all manmade structures shall be accurate to 0.03 m vertically and horizontally. The survey maps shall be at a 1:1000 scale.

Where spot height values are to be derived from tachometric survey, lines of sight shall not exceed 150m.

Information relating to calibration, operation and field validation for this operation shall be documented and included in the survey report.

Alternative methodologies for topographic surveys may be considered, information on Light Detection and Ranging (LiDAR) method is available and may be provided on request at MCA.

4.3.7 Bathymetric (Hydrographic) Survey Surveys will be carried out using a multibeam echo sounder. If a single-beam echo sounder is proposed then the consultant must demonstrate how the survey will meet the criteria set out below.

Soundings will be quoted to 0.01m and shall be reduced to the WGS 84 UTM datum. The position of the sounding shall be indicated by the decimal point and the soundings will be plotted normal to the line of sounding.

Sounding reductions shall be obtained by measurement of the water level from a previously established point, which has been heighted, by level traverse between at least two benchmarks which in turn must be tied to the designated site datum. The misclosure of this traverse shall not exceed 20 mm. The water level reference point shall be photographed and recorded in such a way as to make its recovery positive.

The positional accuracy required for the soundings shall be accurate to better than 1m. Soundings shall be accurate to ±5 cm RMSE.

Line spacing shall be such that the portions of the swathe that meet the accuracy standards shall overlap so that there are no gaps in the coverage. Sounding lines shall generally be parallel. Data acquired during sharp turns shall not be included in the final data and shall not be used to meet coverage requirements.

The consultant shall demonstrate bottom coverage using a raster summary image, color coded by depth and using only the fully corrected data that meets the accuracy requirements.

Where the swathe bathymetry yields insufficient data to cover the survey area, other (possibly land-based) techniques shall be used. These land-based techniques shall comply with accuracy requirements for GPS or tachometric survey as stated in these TOR. Information relating to calibration, operation and field validation for this operation shall be documented and included in the survey report.

The presence of weed and other obstructions to the multibeam shall be noted in


of 81

survey records.

Beams are to be disabled and concentrated as necessary to ensure an even coverage of data over the full reservoir area. The minimum density required is 10 soundings per square meter. The surveyor shall endeavor to stay within a maximum of 50 soundings per square meter.

A plan shall be produced showing areas where no bathymetric observations have been obtained. Raw data shall be processed to derive continuous surface representing depth relative to designated datum. The surface model shall extend to the water edge.

A 5m grid of soundings shall be extracted from the survey data and displayed on the drawings. Plans shall be A0 size and compiled to suit the survey area. Plans shall be provided in hard-copy, .dwg and .pdf format

Sound velocity profiles are to be measured at the start of each day's work and when SV artifacts appear in the data.

An error budget based upon the specifications and experience of the system is to be developed and compared with manufacturer's specifications and survey accuracy requirements.

4.4 Engineering Feasibility Study 4.4.1 Objectives of the Required Services The overall objectives of the feasibility study are to:

• To make an overall assessment of the existing state and safety of Nacala Dam;

• Identify and compare on the basis of cost and technical feasibility solutions for the rehabilitation of Nacala Dam and the raising of the full supply level by 2 m with minimal disruption to the water supply of the City of Nacala.

Detailed study objectives in support of the overall objectives, include but are not limited to the following:

• Establish hydrologic parameters;

• Assess the condition of the existing structure, including but not limited to, the condition of the concrete elements: actual strength, aging effects, and impact of alkali aggregate reaction;

• Provide preliminary detail, if required by the EIA, for a fish way structure;

• Provide preliminary outlet works arrangements;

• Provide preliminary spillway arrangements;


of 81

• Provide preliminary embankment rehabilitation arrangements;

• Provide preliminary intake tower raising arrangements;

• Provide preliminary road diversion arrangement; and

• Provide Scope and Design Criteria for the Detailed Design phase of the project

The detail provided shall be sufficient to allow the client to proceed with the Detailed Design phase. All requirements forthcoming from other studies and not yet known must be incorporated in the design.

4.4.2 General Requirements The consultant shall undertake, but shall not be limited to, the following:

• Review available background material and prepare inception report that details adjustments in methodology and data collection requirements.

• Review the pre-feasibility hydrological modeling studies (which included long-term simulations to assess the firm yield) and develop such hydrological models for Nacala Dam as required to confirm the hydrologic parameters for the design of the dam raising and to provide indicative operating rules;

• Determine flood peaks for dam spillway designs of the Muecula River;

• Determine the “footprint” and capacity of the reservoir and location and amount of land upstream that will be inundated once the new dam wall is raised.

• Assess the sediment load that will be deposited into the storage dam from the catchment of the dam; and make recommendations on appropriate watershed management options.

• Undertake costing and engineering economic analyses of the selected and designed scheme taking into consideration all costs and benefits incurred by the scheme; and

• Design the storage dam to a level of detail that will enable accurate costing.

4.4.3 Hydrologic Analysis The Consultant will review the pre-feasibility hydrological analyses and conduct such hydrologic analysis to establish parameters needed for the preparation of the design tender of the Nacala dam rehabilitation. The Consultant will be required to liaise with the Consultants conducting the associated feasibility studies for Compact-funded works on the Nacala water supply system, in order to obtain estimates for future demand. The hydrologic analysis will include the following:


of 81

(i) Review of hydrological data The Consultant shall review the quality of data available for the hydrological assessment and take adequate measures to resolve the possible implications for the use of the data in subsequent hydrological analyses for the design and operational phases.

(ii) Hydrologic modeling and yield analysis A detailed water budget should be undertaken with the reservoir in its present state and after raising the dam elevation. Such an analysis would quantify the net gains in raising the dam by 2m as compared to the existing storage. A standard 30-year climatology of monthly flows should be established as part of the feasibility assessment. A hydrologic time series of such length would include sufficient instances of both dry and wet years necessary to represent the range of hydrologic conditions at the site.

(iii) Preliminary operating rules The Consultant should investigate and propose reservoir operating rules that ensure the safe and sustainable management of water in the reservoir through the variety of drought, flood and cyclonic events that frequently impact Mozambique. The operating rules should aim to establish procedures for minimizing sediment buildup in the dam, minimizing risk of overtopping during high flow periods, water use priorities and schedules during periods of drought, minimum ecological releases to meet downstream requirements.

(iv) Flood peak analysis For emergency spillway design, peak flows associated with historical flows as well as large tropical cyclones making landfall should be estimated. A rainfall climatology associated with the largest tropical storms impacting any part of the Mozambican coast should be established, and peak hourly flows associated with routing these storms to the dam should be assessed. Peak flows associated with rare events should be estimated from both any historical flows and potential flows associated with tropical cyclones to provide a sound the basis for emergency spillway design. The return periods to be used should comply with locally applicable standards taking account of (1) the potential loss of life and damage to property associated with failure and (2) the costs associated with the disruption of Nacala’s primary raw water source. If there is a significant discrepancy between locally applicable standards and the return period that would be required under international best practice the Consultant should carry out the analysis for both. The climatology of events used in the peak flow analysis should be provided to the client for future use in reservoir operation.

(v) Sediment load analysis An assessment should be made of historical reservoir sedimentation rates from the construction of the reservoir to the present, and a comparison made with results from a survey in 2001. The historical sediment loading analysis would also provide a basis for predicting future siltation rates and operating rules for dealing with high sediment flows, and a basis for developing appropriate watershed management options to minimize sediment delivery. Potential impacts of reservoir sedimentation on reservoir volume-area-stage rating curves should also be assessed.

4.4.4 Nacala Dam Rehabilitation and Rising A preliminary evaluation of the alternatives for diverting the N13 road that runs along the embankment shows that it may be more economical to do a temporary deviation, rather than a permanent one. This needs to be confirmed once a better terrain survey is available. The route of the deviation should be chosen to follow the best alignment through the settlements that will be affected. It may also be possible to design the raising works such that the need for any road diversion is removed altogether.

The Nacala Dam rehabilitation and raising work needs to address the following:

• The existing gated spillway, which is in a state of disrepair and has an inadequate capacity, should be replaced with a free overflow spillway to achieve the required capacity;

• The dam embankment is not internally stable as the core is potentially dispersive and there is no chimney or blanket filter for intercepting seepage water and draining it from the embankment;

• The material used to repair the embankment after the floods of 1982 may be a permeable gravel material which could be removed and replaced with an impermeable core section, suitable material on the flanks and a downstream filter;

• An embankment outlet works needs to be provided for Environmental Flow Releases established during the Environmental Impact Evaluation process (Avaliação de Impacto Ambiental, or AIA); and

• The existing Full Supply Level for the dam needs to be raised by 2m.

4.4.5 Scoping and Detailed Design Criteria The Consultant shall provide the scope and detailed design criteria for the detailed design phase. This must include design criteria for the embankments, spillways, outlet works, and river management during construction, access roads, bridges, geotechnical work, seismicity, structures, hydraulics, valves, pipelines, electrical works and instrumentation.

4.4.6 Additional Requirements Clear conclusions and recommendations of the study will be presented in a report which will include the summary of the work done, assumptions made, reasoning behind the conclusions and recommendations, photographs, maps and graphs and an executive summary. The above will be summarized in PowerPoint presentation for MCA and key stakeholders including but not limited to: ARA-Centro Norte, DNA-GOH, Nacala Authorities, Asset Management Unit and the Provincial Water Board. The Consultant must plan for two presentations to the Stakeholders in public meetings to be held in Nacala, one after the Inception Phase of the study and the other near the close of the study before firming up on the final recommendations of the report. The Consultant will be able to present and respond to questions in both Portuguese and English. The Client reserves the right to stop the work if the above is


of 81

not adhered to. The study proposal and budget must allow for at least five scheduled project meetings for the duration of the study. The Consultant will arrange / schedule these meetings in accordance with the study program. The Consultant shall circulate agendas, minutes, provide updated expenditure programs, keep a record of decisions, make presentation on the technical work done and any problems experienced, etc. The project meetings will be held in the offices of the MCA in Maputo and at least two in Nacala.

4.5 Environmental Impact Assessment 4.5.1 Objectives and Outcomes of the Consultancy The objective is to generate a sound and robust Environmental Impact Evaluation process, known as the Avaliação de Impacto Ambiental (AIA), for the proposed project focusing on the raising of the Nacala Dam wall and associated temporary or permanent crest road deviation. The AIA is the entire set of procedures from the submission of initial information about the proposed activity for pre-assessment, to the preparation of the Environmental Impact Assessment (EIA) and Environmental Management Plan (EMP), through to the issuing of an environmental license.

4.5.2 Required Approach The Mozambican law’s key instrument is the Environmental License which precedes the issuance of any other legally required license. An Environmental License can only be granted based on an EIA and associated EMP, as the instrument to prevent environmental degradation. The legal basis for the EIA is provided under the Mozambique Environmental Law. An Environmental Impact Assessment must be carried out by entities officially recognized and accredited by the Mozambican Government.

In addition to the above, the water sector has developed environmental guidance documents which should be taken into account, namely “Guidance on Environmental Assessment and Management of the National Water Development Project” (2003) and a ‘Generic Framework Environmental Management Plan for Construction Works’ (2004), both documents issued by FIPAG.

Both the MCC Environmental Guidelines and Mozambican environmental law adopt a process of screening, scoping, assessment and mitigation. Projects must be registered with the environment ministry, MICOA, to be categorized. When a large dam project like this one is screened and categorized as a Category “A” project, an Environmental Pre-feasibility and Scoping Activity (Estudo de Pré-viabilidade Ambiental e Definição do Âmbito, or EPDA) accompanied by TORs and a Preliminary Environmental Information Form must be sent to MICOA for approval.

The scoping phase is followed by the study of environmental impacts. During this stage, baseline data are collected with regard to the issues defined in the ToRs outlined during the scoping phase. In addition, a careful description of the project is made in order to identify the actions that might have an environmental and social impact during the construction, operation and decommissioning of the project.

The baseline description of the environment and the descriptions of the actions are combined to identify possible impacts and assess their nature, direction, likelihood,


of 81

significance and magnitude. On the basis of this assessment, proposals are developed to enhance positive and mitigate negative impacts and a plan is designed for the implementation of these proposals and the monitoring of the project’s impact. Proposals are also developed to ensure sustainability of the scheme. The EIA study should contain, at the least:

• A non-technical Summary of the project;

• A Main Report describing:

o Proposed activities;

o Baseline environmental and social conditions in the project area;

o Modifications of the various environmental elements as consequence of the project; and

o Mitigating measures to eliminate or reduce the negative impacts on the environmental quality and measures to ensure sustainability;

• Annexes to the Main Report, including control and monitoring mechanisms in the form of an EMP as an Annex.

The environmental and social impacts identified in the construction, operation and decommissioning phases should be presented to determine the following:

• Magnitude of impact [short, medium and long-term];

• Nature of impact [positive or negative - direct or indirect – temporary or permanent];

• Intensity of impact [low, medium or high];

• Duration of impact [short, medium or long-term];

• Probability of impact [low, medium or high].

Each component will be assessed according to a sliding scale ranging through major adverse, moderate adverse, neutral, moderate beneficial and major beneficial. These assessments should be based on a clear comparison between the existing baseline and the new proposals and also on well defined and robust criteria relating to each component. The EIA should have a clear conclusion.

4.5.3 Factors to Consider During the EIA Process Following proper scoping but before the detailed EIA, iterative design of the proposals must be jointly worked out by the project Environmental Team Leader and Engineer, in cooperation with the Client where appropriate. In this way adverse impacts are designed out as far as possible rather than leaving them to be mitigated at a later stage. Thus land take, especially from agriculture and settlements, should be minimized in relation to dam raising, the new or diverted road and all other infrastructure. Borrow pits or quarries created or modified to provide construction


of 81

materials should also be designed and located to maximize habitat creation but minimize disturbance and malaria risk to adjacent settlements.

Downstream compensation flows must be sufficient to sustain existing settlements, fisheries and mangroves. Added value may also be achieved through habitat creation. Thus tree planting and increase in miombo woodland habitat may be achieved both around the reservoir and downstream though this must be done through close coordination with the local community. Subsidiary small dams on existing creeks within the present reservoir should be considered as these can create small permanent water bodies without regular draw-down which are especially valuable for aquatic vegetation, fish spawning, and birdlife. Later mitigations should include health provisions for the immediate community and good environmental management of construction operations.

Sustainability should be a key consideration, with appropriate attention to watershed management, including socio-economic aspects and activities upstream of the Dam.

Women and vulnerable groups need to be clearly represented in the EIA process, including consultation, scoping, impact assessment and mitigation. Gender disaggregated data should be provided and the EIA should consider individual beneficiary target groups. The EIA process should also include an assessment of public health and safety impacts associated with this investment.

4.5.4 Scope of Services

Specific issues to be evaluated are listed below. The evaluations require baseline information, impact identification and attribution of significance, risk assessments,


of 81

mitigation measures and management recommendations. Management measures to be detailed in an EMP will need to minimize, eliminate, or monitor the possible impacts identified.

(i) Downstream Environmental Releases The project will - for the first time since the construction of the original Nacala Dam - make provisions for environmental releases downstream. The assessment of appropriate environmental releases should be carried out as part of the iterative design process and should due to the necessary trade off between enhanced river flows downstream and the reduced yield of the enlarged reservoir. The assessment of appropriate environmental releases must take into account the present artificial conditions in the river immediately downstream of the dam and the impact that this ongoing situation has had on the baseline environmental conditions.

(ii) Biophysical Aspects

Evaluation of the potential influence of the raised Nacala Dam, or construction works, on the geomorphology, geology and quality and stability of the soils of the area of the project and surrounding areas and vice-versa.

(a) Geomorphology and geology

The results of the hydrological assessment of operating rules, reservoir yield, sediment load, water quality and design flood calculations undertaken for the feasibility/design should be reported in the EIA with supporting maps and charts.

(b) Hydrological assessment

In addition evaluation of the following is required:

• Ambient hydrogeological assessment including aquifer types and classification;

• Evaluation of groundwater/surface water interactions and recharge and any potential environmental impact on these from the raised dam;

• Surface water environment downstream of the dam to the coast including wetlands; and

• The identification of a ground and surface water monitoring network and possible data shortfalls.

The consultant shall carry out an evaluation of the possible impacts that the proposed facilities and operations will have on the geology, surface water, wetlands, and groundwater environments.

(c) Hydrocensus

The fieldwork needs to include a hydrocensus and chemical sampling, with recording of the following parameters:

• GPS locations of boreholes, springs, wetlands, and surface water bodies;

• Surface water flow patterns and identify down stream users;


of 81

• Borehole depths and yields;

• Spring location and yields; and

• Field quality parameters, including electrical conductivity, temperature and pH measurements.

An evaluation of air quality, particularly during the construction phase, of project influence on surrounding communities and biodiversity, should be conducted.

(d) Air Quality

An evaluation of flood and earthquake risks in the project vicinity, as well as processes of erosion, sediment deposition, stability of slopes and their influence on the dam’s environmental impact and vice-versa should be conducted.

(e) Process

(iii) Biological/Ecological Aspects:

An evaluation of environmental impact of the raised dam up and downstream on woodland and wetland conservation, river and habitat of conservation importance.

(a) Habitats

An evaluation of environmental impact -- of the raised dam upstream and downstream -- on terrestrial and aquatic flora and fauna; and on species of conservation concern.

(b) Species

An evaluation of environmental impact of the raised dam up and downstream on land use that supports livelihoods including croplands, fuel woods, medicinal plants, wild games, livestock, beekeeping and fishing.

(c) Renewable natural resources:

An evaluation of environmental impact on up and downstream processes of eutrophication, salinization, food chains, movement of terrestrial and aquatic species, insect borne diseases, aquatic weeds.

(d) Process

A detailed habitat assessment of the proposed area to be inundated, when the dam is raised, must be conducted in order to:

(e) Potential Upstream Impacts:

• Identify and sample floristic and faunal attributes within the proposed area, with specific reference to species diversity, endangered species and sensitive environmental features and attributes;

• Consider the effect of potential impacts on floristic communities and faunal assemblages;

• Describe floristic communities and faunal assemblages;

• Combine separate floristic and faunal results to present an ecological overview of the proposed development;


of 81

• Consider the potential impact of the proposed development on the ecological environment;

• Highlight areas of particular concern;

• Provide recommendations in terms of possible realignments of the proposed development as part of the iterative design process;

• Provide recommendations in terms of the mitigation of potential impacts during and subsequent to the construction phase, operational phase and decommissioning phase; and

• Present results of the evaluation as part of the EIA;

In particular the baseline condition of the riverine and aquatic habitats, flora and fauna downstream of the Nacala Dam should be considered in terms of the situation in similar natural catchments without the presence of a dam to help assess what might be appropriate environmental releases from the enlarged reservoir.

(f) Potential Downstream Impacts

• The main focus of the faunal assessment will be placed on the assessment of the availability and status characteristics of habitat that support animal assemblages and endangered species. Such attributes typically include:

o Floristic communities and variations;

o Soil and land type attributes;

o Geological characteristics;

o Slope and aspect; and

o Wetland-related aspects such as surface water, flow and riverine vegetation.

• Relevant maps must be compiled to highlight sensitive environments.

• A detailed in-stream habitat assessment of the proposed area will be conducted and where these issues are duplicated in the above biodiversity assessment they will be omitted. Water quality and Flow alterations up and down stream should be assessed.

The study should focus on the following aspects of the riverine ecology: (g) Riverine Vegetation

• Channel zone

• Channel bank zone

• Floodplain zone

• Floodplain bank zone


of 81

• Vegetation of alluvial fan areas

• Presence of Endangered Species.

• Species occurrence and general distribution (h) Ichthyofauna

• General habitat preferences of sampled species

• Presence of endangered Species or species of high conservation importance

• Effects on fish in the river system

• Qualitative sampling based on SASS5 (South African Scoring System Index) (i) Aquatic Macro invertebrates

• Use of Habitat Quality Index to evaluate the condition of habitat

• Assessment of habitat utilization, with special reference to the possible effect of flow alterations.

• Possible effect of the Nacala Dam project on aquatic macro invertebrates

• The data collected must:

o Identify potential impacts on Ichthyofauna, aquatic macro invertebrates and riverine vegetation.

o Assess the significance of the impacts

o Develop mitigation and management issues for the project.

• The results should be subjected to the same Impact Evaluation Procedure in order to evaluate the significance of impacts on the ecological environment. Based on this specific recommendations must be made in order to limit the impact of the proposed development on the ecological environment to a minimum.

(v) Socio-Economic Impact and Gender Aspects and Analysis Loss of land from inundation can result in serious project implications with regard to resettlement impact and loss of agriculture land. When physical displacement of households occurs or affected parties lose rights or access to productive assets (including farmland, crops, etc), there is always potential for negative socio-economic impacts and social conflict. Even without physical displacement, changes in upstream and downstream flows from Dam rehabilitation can negatively impact the livelihoods and health of local people.

To address these concerns, the Consultant will develop a detailed socio-economic assessment, as part of the overall EIA, that identifies social impacts, and provides recommendations to mitigate these impacts. The Consultant shall consider gender and vulnerable group issues throughout the EIA process and present key findings


of 81

and recommendations with regard to these issues in the final report. The final report should include gender disaggregated beneficiary data in the baseline, and quantitative performance indicators to measure and track gender participation in the monitoring plan. In addition, the EIA needs to reflect consultation with local and international NGOs and CBOs involved in community development activities related to water supply, hygiene, health and sanitation as well as gender.

The socio-economic assessment must use a methodology that includes key informant interviews with local leaders (government, traditional leader, church leaders, etc) key workers (schools, clinics) and NGO and CSO leaders. It should include focus groups and/ or interviews with men, women and youth, whose livelihoods depend on the local environment. Details of interviews/focus groups (names and dates) should be provided in support of the assessment.

The socio-economic baseline assessment should include the following components:

• Maps delineating different areas of impact, both upstream and downstream, identifying zones of land use, and the different livelihoods that these land uses support.

• A description of the community structures: official leadership structures and other institutions that are important to the community. Description of main NGOs and CSOs that are active in the area and their activities;

• A description of the population/demographics of the area of impact. Accurate statistics are often hard to come by, but local leaders, district and health officials, local CSOs and NGOs can often provide this information.

• A description of the primary social services in the area of impact: including quality of services delivery – especially water, sanitation and waste management, health services, and schools.

• A description of important cultural, historical, archaeological sites in the area of impact;

• A description of land types and land uses in the area of impact. (e.g, what kind of farming system (s) are in operation - dry land farming, irrigation agriculture, what are the main food crops /cash crops?);

• A gender and livelihoods assessment that considers the following issues:

• What are the main food sources of income of poor and non-poor households? What are the main cash sources of income? How much water do these households use and how is this water obtained?

• What are the main responsibilities of women and men in terms of supporting the household – e.g. division of labor in farming, water collection, wood fuel collection? What are the main responsibilities of men? (e.g, Farming, livestock-keeping).


of 81

Note that the Consultant should provide sufficient detail in this socio-economic analysis so that it may serve as the socio-economic baseline for the resettlement action plan.

Considering the data gathered and issues examined during the socio-economic baseline assessment, the Consultant will identify the various positive and negative socio-economic impacts of the dam on each of the different groups of people (including differentiated impacts for men and women) and the economic activities described in the baseline.

• What are the induced and cumulative impacts on natural resource based livelihoods? Will the impacts be different on women compared to men?

• Are there any groups that are particularly vulnerable? Who are they? Where do they live? And what makes them vulnerable?

• What are the risks to health and safety that may occur during the construction and operation of the dam?

The Consultant should also identify measures to minimize or eliminate the negative socio-economic impacts during dam reconstruction and operation and provide detailed mitigation measures in the EMPs.

(vi) Resettlement Impacts The Nacala Dam project may involve physical and/or economic resettlement, as a result of the raising of the dam wall, expansion of the reservoir, and the temporary or permanent rerouting of the N13 highway. Resettlement may be caused by (1) the detour road, whether temporary or permanent, (2) the borrow pits, (3) the enlarged footprint of the reservoir caused by raising the dam height, and (4) the rehabilitation of the dam and its associated works including the outlet works, the spillway, the fish way, and the embankment rehabilitation.

Mozambican environmental law underscores citizen’s rights to information, justice and compensation if any environmental entitlements, including the loss of crops or profits and the temporary or definitive interruption of economic activities, are infringed upon. International good practice entails assisting displaced person in their efforts to improve their standards of living or at least restore them to pre-project levels.

As part of the EIA process, the extent of resettlement will be scoped out and means of minimizing or avoiding resettlement will be explored, especially with regard to the temporary re-routing of the N13 Highway. The resettlement scoping will be carried out in compliance with the World Bank Operational Policy on Involuntary Resettlement (OP 4.12), GoM applicable laws and regulation, and MCC Environmental Guidelines. The resettlement principles for this project that must be reflected in resettlement scoping are that:

• Involuntary resettlement will be avoided where feasible, or minimized, by exploring all viable alternative project designs;


of 81

• Where it is not feasible to avoid resettlement, resettlement activities will be designed and executed as sustainable development projects, by providing sufficient investment resources to enable the persons displaced by the project to share in project benefits;

• Displaced persons, with special attention to women and vulnerable groups, will be meaningfully consulted and have opportunities to participate in planning and implementing resettlement programs;

• Displaced persons will be assisted in their efforts to improve their livelihoods and standards of living or at least to restore them, in real terms, to pre-displacement levels or to levels prevailing prior to the beginning of project implementation, whichever is higher.

The socio-economic chapter of the EIS will be sufficiently detailed to provide a socio-economic baseline for the resettlement planning instrument. Subtask Deliverable.

(vii) Undertake a Full and Comprehensive Public Participation Process

A complete draft of the EIA in Portuguese and English that covers all expected direct, indirect, induced, and cumulative environmental and social impacts (including the resettlement scoping). The Consultant will develop this EIA sufficiently so as to allow MCA/DNA-GOH to get MICOA and MCC approvals. As such, the EIA shall be compliant with Decree Number 45/2004, General Directive Numbers 129/2006 and 130/2006 of the GoM, MCC Environmental Guidelines and MCC’s Policy on Gender.

Public consultation for all “Category A” Environmental Impact Assessments is a requirement of the GoM, and the MCC.

Project-affected groups and local Non-governmental Organizations (NGOs) need to be consulted about the project’s environmental and social aspects and their views taken into account. Provincial and district health authorities, and departments responsible for public safety, need to be involved in the consultation process. During screening and scoping, the project is introduced to key stakeholders to ensure the main issues have been identified and there is agreement on the assessment methodology.

During the EIA process, public consultation is undertaken to collect the opinions and information about the baseline, impacts and mitigation. Consultation with project affected people (Partes Interessadas e Afectadas, or PI&As) is essential and the appropriate resettlement planning instrument will ensure that PI&As are consulted


of 81

on and participate in resettlement decision making. Special efforts need to be made to include women and vulnerable groups.

It should be noted that public participation is divided into two phases, the first one running between the application for pre-assessment (EPDA), and the submission of the EIA to MICOA; and the second running between the review of the EIA by MICOA and the issuing of the environmental license. The first phase is the responsibility of the Consultant, while the second phase is the responsibility of MICOA. The Consultant shall be responsible for providing information to all concerned and affected parties on the project, for consulting with the parties on a regular basis throughout the period of preparation of the EIA, for providing an opportunity for public review and comment of the draft EIA, and for preparing a Public Consultation Report for submittal to the environmental regulatory authority that summarizes all comments. All information must be provided in the local language. Public meetings should be held in convenient locations, and must be announced publicly by communicating directly with stakeholders (PI&As) and publishing advertisements in local news media at least 15 days prior to the proposed meeting date. Stakeholders within the zones of influence of the Nacala Dam and temporary realignment of N13 shall be provided opportunity for public review and comment of draft reports.

The Public Consultation Report shall include the following:

• Name of activity, applicant, and location and date of report;

On his/her return to the client this official should be provided with the necessary means and assistance to enable the implementation of similar procedures and processes.

During the contraction phase the Consultant shall also provide training to a team of up to six officials in the inspection, operation and maintenance of the dam. The training shall include the reading and maintenance of the instrumentation and the operation and maintenance of the hydro-electrical and hydro-mechanical equipment, and the general maintenance and surveillance of the dam structures. The training will be carried out by experience members of the Consultant’s team and will include one week of classroom training and two weeks of practical experience. The Consultant will set written and practical examinations during the training and provide course notes for the officials to retain.

The Consultant shall provide a concise status report to the Client on the activity and performance of each seconded official at agreed intervals and/or on his/her return. Any requirement related to the seconded staff shall be met in accordance with the provisions.

4.7.13 Development and Implementation of a Resettlement Action Plan During the detailed design phase, the Consultant will be responsible for drafting a resettlement action plan and supporting the implementation of resettlement activities.

(i) Development of a Resettlement Action Plan Resettlement (economic or physical displacement) may involve one or more of the following: a) land acquisition; b) other asset acquisition (e.g., homes or other physical structures, trees, crops); c) physical relocation; and d) loss of access to resources (e.g. grazing lands, pastures, fishing grounds or collection areas for medicinal plants, weaving materials or similar resources).


of 81

A fundamental requirement of resettlement activities based on OP 4.12 is to restore, at least, standards of living and preferably improve the livelihoods of those households, families, extended families and individuals who are losing land, assets or access to resources due to the implementation of a project. Compensation for lost assets can be monetary, in-kind (e.g., new land, housing and social infrastructure, work places or other replacement for lost assets) or a combination of both. Compensation to address economic rehabilitation can be in the form of restoration of conditions for pursuit of economic activities or training for new vocations where the original source of livelihood cannot be restored.

Several additional important principles of resettlement activities based on OP 4.12 relate to consultation and the form of compensation payments. Project-affected persons (PAPs) are to be: (i) informed about their options and rights pertaining to resettlement; (ii) consulted on, offered choices among, and provided with technically and economically feasible resettlement alternatives; and (iii) provided prompt and effective compensation at full replacement cost for losses of assets attributable directly to the project. When land taken is the primary source of income and livelihood, PAPs should be provided with land (“land for land”) for which a combination of productive potential, locational advantages, and other factors is at least equivalent to the advantages of the land taken. In some situations, moving assistance or allowances and compensation for lost income during the move and the cost of re-establishing a livelihood (for example, at a new work place or prior to planting a new crop) will be provided. When new housing or work places are more distant from each other than prior to resettlement, transportation allowances may be required in order to avoid loss of income. The RAP will describe the entire compensation package as applicable to the various situations of PAPs and will include a grievance process that includes informal as well as formal or administrative measures to deal with disputes when they arise. The RAP will also include a detailed budget and description of the particular mechanisms for any monetary compensation.

Affected parties that have formal title or ownership rights over the land or asset subject to taking for implementation of a project are entitled to compensation (at replacement cost) for the land and any improvements upon that land. Those who are living on or using land for which they do not have a recognizable legal right or claim (for example, “squatters” on public land within an existing right of way or tenant farmers) are entitled to resettlement assistance, such as compensation for the improvements upon that land (homes, market stalls, crops, etc.), but not for the land itself. In countries where the government claims to own all land that is not specifically alienated through a legal title and/or customary titles or uses are common, entitlements must be carefully analyzed in order to ensure fair and equitable treatment of affected parties.

Resettlement scoping in the feasibility stage will provide useful background information, namely the project’s legal framework, the socio-economic baseline and an identification of potential PAPs. Pre-feasibility estimates indicate that approximately 15 to 50 households will lose property (land, productive assets, buildings, etc.) as a result of the project and will need to be included in the RAP. If the Consultant determines a fewer than 200 people are displaced or if all affected people lose less than 10 percent of their productive assets, an abbreviated RAP as


of 81

described in Annex A of Op 4.12 may be developed in lieu of a full Resettlement Action Plan. The decision to develop an Abbreviated Resettlement Action Plan instead of a full Resettlement Action Plan must be approved prior to the Consultant initiating develop of such plan.

During detailed design phase, the Consultant shall develop a Resettlement Action Plan (RAP) covering all aspects of the Nacala Dam Project that is fully compliant with OP 4.12 and national legislation, including the Mozambican Lei de Terras No. 19 (1997) and its Regulation (Decree 66, 1998). The RAP must consist of at least the following information:

a) Description of the project and potential resettlement impacts.

b) Description of measures taken to ensure that the project is implemented to minimize displacement;

c) Results of census survey, assets inventory, and socioeconomic survey including, at a minimum:

i. Categories of impacts, people affected, and the magnitude of expected loss;

ii. Information on vulnerable groups including women

iii. Standard characteristics of the affected people including a description of their sources of income and living standards

d) Description of the consultation strategy, summary of views expressed, how these views were taken into account, and how the proposed RAP was shared with affected people (e.g., community meetings, notice boards, and an information pamphlet for all affected households).

e) Description of the proposed monitoring and evaluation system, such as census updates, resource assessments, socioeconomic surveys, etc.

f) Description of grievance procedures.

g) Estimate of the case-by case cost of relocation and compensation. A detailed cost schedule shall be prepared that includes, at a minimum:

i. Replacement lands commensurate with lands to be displaced;

ii. Compensation for replacement of existing structures (partially or fully);

iii. Compensation for lost crops, trees, and other productive assets;

iv. Costs for economic rehabilitation;

v. Transitional allowances to offset loss for income resulting from relocation or temporary loss of productive assets;

vi. Allowances to defray the cost of moving;


of 81

vii. Administrative costs; and

viii. Contingency budget (with detailed explanation of contingencies).

d. Analysis of the GoM legal framework for resettlement and compensation, as applied to the Nacala Dam Project including, at a minimum:

i. Identification of all relevant laws and customs at the national, provincial, and local levels;

ii. Gaps between relevant laws and OP 4.12, and measures needed to fill these gaps;

iii. Description of entitlement policies and eligibility criteria for each category of impact; and

iv. Description of method of valuation used for affected structures, land, trees, crops and other assets; and

v. Entitlement matrix.

e. Definition of specific tasks and implementation schedules for conducting and completing the relocation process including resettlement site selection and preparation, which reflects experience in Mozambique in conducting similar relocation activities.

f. Description of measures to replace any lost housing, community infrastructure and social services.

g. Detailed design of resettlement structures.

h. TORs for Supervision of RAP Implementation and bidding documents for construction of resettlement structures.

i. Standards for ensuring that displaced parties (DPs) are relocated to environmental situations similar to those at their current sites.

j. A description of organizational responsibilities for implementing resettlement including identification of responsible agencies and any necessary measures to strengthen capacity to implement the RAP.

k. Documentation of preliminary agreements with each of the PAPs with regard to the amount and nature of the compensation to be provided.

The sub-task deliverable comprises a Resettlement Action Plan (or Abbreviated Resettlement Action Plan, as relevant) in Portuguese and English that is compliant with WB OP 4.12 and GoM national legislation. This RAP is subject to approval by relevant GoM authorities and MCC and will include the ToR for supervision of RAP implementation and the bidding documents for construction of resettlement infrastructures.


of 81

(ii) Option for RAP Implementation Services

MCA, through DNA-GOH, has the primary responsibility for overseeing the implementation of the RAP. However, following completion and MCA-MZ/DNA-GOH/MCC acceptance of the RAP, the Consultant may be requested to assist with implementation of the RAP. The Consultant may be requested to provide, among other things, the following services:

a) Mediate between MCA-Mozambique and the affected parties during the final negotiations of the compensation to be provided (including monetary and in-kind);

b) Establish an effective grievance redress mechanism according to the terms and conditions as described in the RAP.

c) Prepare legal documentation and other paperwork required in order to make compensation payments, acquisition of assets, and other resettlement activities official and/or legally binding.

d) Facilitate the transfer of monetary-based compensation from MCA-Mozambique/GoM to the PAPs.

e) Facilitate and support the logistics of acquisition/transfer of in-kind compensation (seeds and replacement of crops)

f) Supervise the construction of any small infrastructure (replacement houses, fences, physical structures) that is being offered to PAPs as in-kind compensation for lost asset

Resettlement monitoring and evaluation will accompany RAP implementation and income restoration. This will allow for appropriate modifications and improvements to contribute to a smooth, transparent and effective resettlement process. Monitoring reports will need to be provided regularly to decision makers and the Consultant will be requested to produce monthly reports regarding RAP implementation. The RAP will identify key indicators and issues that need to be tracked and the Consultant shall report against those key indicators. One of the most important issues the monthly report will need to address will be grievances and their resolution. OP 4.12 generally requires that resettlement activities required for project implementation be completed before the affected land, asset or resource is taken for construction or other project use. In particular, taking of land and related assets may take place only after appropriate compensation and other assistance as contemplated by the RAP has been provided to the PAP. MCA entities may initiate procurement actions related to project implementation, sign contracts, and allow contractors to mobilize prior to and during the resettlement and compensation process, however no construction or implementation activities that involve the taking or use of the asset or land in question may take place until the affected party has received appropriate compensation and other assistance contemplated by the RAP.


of 81

If the Consultant is requested by to assist with RAP implementation, a detailed scope of work will be provided by MCA-MZ/DNA-GOH for these services. These tasks will be the subject of a contract amendment, based on the extent of RAP requirements. At this time, the Consultant shall not include in its Financial Proposal any costs for RAP implementation services.

The sub task deliverable is support of the implementation of the RAP and monthly reports focusing on assistance provided to MCA.

The CS Team shall monitor the work and request updated schedules from the Contractor when the works are behind schedule.

(iv) Works Quality Control and Inspection in the Field The aim of quality control is to ensure that all implemented works are in compliance with the requirements of drawings and technical specifications.

Quality control over construction stages is a lengthy process, requiring thorough checking and recording of all construction operations, including:

• Selection of construction materials;

• Concrete mix composition;

• Materials production according to the approved concrete mix composition;

• Construction works applying appropriate methods;

• Adequate use and observation of installations and equipment; and

• Selection of samples and testing of materials.

The significance of consistent quality control should be a priority of the CS Team over the various stages of construction, i.e. work shall be satisfactorily completed prior to starting the following stage of work.

All the testing and sampling, including testing of materials, completed work and parts of structures, will be implemented in the corresponding laboratories. When reliability of any data proves to be questionable (e.g. statistic discrepancy of results), this information shall be immediately conveyed to the Client.

Efficient quality control requires that the CS Team keep a daily journal of the construction, inspection reports and notes for accurate reflection of construction progress and works performance. The information to be registered daily includes, but is not limited to, the following:


of 81

• Significant events at site;

• Climatic conditions;

• Number of hours influenced by unfavorable climatic conditions;

• Workers, equipment and materials available at the site;

• Equipment down-time;

• Teaching safety engineering and its application;

• Measurements data, original ground levels, other data;

• Amendments to drawings;

• Construction sequence;

• Results of all the tests and examinations;

• Damage of property and/or injury of people; and

• Other events like visits of authorities.

• Earned Value and/or other performance metrics

If CS Team sees the Contractor performing poor quality work then the CS Team should provide written instructions for the Contractor to improve the work, and in some exceptional cases, to request the work be stopped. Given the serious nature of work stoppage, any such written stoppage request should be made only after agreement with MCA.

The CS Team is responsible for inspection of on-going works at the site. The purpose of inspection is a timely disclosure of construction defects and assurance of construction quality.

• Watch batching operation to determine accuracy of measurements of sand, aggregate, water, and cement. Monitor and record weights;

• Monitor and ensure that the Works Contractor prepares and submits an EMP implementation plan (also referred to as a Contractor EMP) for Consultant/ /MCA approval, and—following the approval—that the construction contract activities are in strict compliance with EMPs, in accordance with the corresponding EMP implementation plans. The Consultant shall propose measures to resolve all environmental/social issues to ensure proper project schedule implementation, thereby averting work delays and related contractor’s claims.

• Monitor Contractor’s methods. If methods result in poor alignment and poor quality of work, the Supervisor must inform the Contractors that improvements will be required. If the Contractors do not address these requirements to the satisfaction of the CS Team, the CS Team shall inform MCA that a work stoppage is warranted and has been carefully considered; and

• Check and signing of certificates of hidden works performed by the Contractor.

The Consultant's CS Team is fully responsible for data included in the reports and invoices.

(v) Contract Management In the process of construction it may become necessary to modify original drawings and specifications or prepare additional drawings due to field conditions or specific circumstances which do not allow for use of available drawings, including unexpected environmental or social impacts.

If the CS Team requests from the Contractor to perform additional works not provided by the original design or to review a part of works, the Contractor will be provided with a written scope of work (SOW) by the CS Team. The SOW will be prepared by CS Team with the concurrence of MCA. Inclusion of extra-work and/or changes in design shall be accompanied by submission of Variation Order.

If changes in designs are required, the Contractor, MCA, and Consultant (CS Team and Design Group of the Consultant) shall discuss the issue collectively.
