Project Intent

1. Introduction The International Cricket Council elected Maldives to be a member country for T-20 matches, for the purpose of promoting the game in the island nation. This coincides with the aims of the Government to promote the game and develop a 20000 seating capacity, world-class cricket stadium that can be used both locally and to host international T-20 cricketing events. Working towards the above, Housing Development Corporation of Maldives has appointed M/S. Collage Design Pvt. Ltd. on 29th September, 2019 for developing Detail Project Report including Conceptual Programming, Master Planning, Architectural Guidelines and Sports Consultancy for Maldives International Cricket Stadium. 1.1 History of Cricket in Maldives Cricket has a long history in the Maldives. A form of cricket called “Filaagandu Boalha” (Wood plank ball) was introduced to the Maldives around 1880 by a scholar who returned from Ceylon (Sri Lanka). The game was progressively adopted over these years. Formal cricket rules and regulations were first introduced around 1920. The year also marked the formation of the first cricket club in the Maldives, the Male’ Cricket Club. The Cricket Control Board of Maldives (CCBM) was established on 1 January 1983 by the government to promote and develop the game of cricket in the Maldives. The Maldives became a member of the Asian Cricket Council in 1996, and an affiliate member of the International Cricket Council in 1998. The development programme is conducted within an overall vision for the future of the game which was formulated in 1999. In 1999, goals were set and a wide ranging development programme was inaugurated to revive and consolidate the great game of cricket. The Board’s development programme is built around the theme “Cricket for the Year 2000 and Beyond”, which is specifically aimed at introducing cricket to school children with the long term aim of creating a new generation of talented cricketers who will represent the country. The national cricket team began representing Maldives in the Twenty20 early this year, when ICC made the decision to grant the country with full Twenty20 International (T20I) status. On that account, the aim of this project is to nurture a love for cricket amongst all Maldivians. And the government believes that this can be achieved with the help of India.

Project Scope

The playing surface shall be natural grass incorporating permanent drainage and irrigation points.. The field and pitch must drain well and the grass be cut short to result in a fast outfield.

1.1.2 The Pitch

Pitches will be orientated north to south. A total of 5 pitches will be provided with the spacing of 3.66 meters between the pitches.

The pitch should have ‘true bounce’ throughout for the duration of the game, and be of reasonable pace. The pitch cover shall be provided to cover all pitches and shall have a raised rim built into its edge, and have 4 discharge outlets at its corners to allow water that collects on the cover during rain to be discharged into the field drainage system. The bowler’s run-ups shall be provided with adequate covers.

1.1.3 Boundary & Moat

The boundary shall be a minimum distance of 3 yards (2.74 m) inside the perimeter fencing, advertising signs, or first obstruction.

ENLARGED PLAN

A continuous Fence / Moat will be provided around the stadium in front of the spectator seating.

It is important under emergency circumstances to allow access across the moat on to the playing area and therefore a method of bridging the ‘gap’ will be incorporated, either on a permanent or temporary basis.

1.2 Turf Protection

Turf protection is to be provided to allow for the change in events from cricket to a concert and back again. Turf protection tiles are used to achieve this change. These tiles are Translucent which allows for photosynthesis to continue and therefore not damaging the turf.

To be considered as additional scope of work. Not to be considered in current scope of work.

Project Scope

1.3 Turf Drainage Design

After years of research, cricket fields are now constructed with the most optimum sub-surface drainage solution for the cricket fields to sustain low/moderate/variable/extreme climatic conditions. The System provides stadium and playing field owners and their caretakers the ability to promote healthier, stronger, and safer turf by accelerating moisture removal and increasing the amount of oxygen to the root zone. As a result, the system helps provide an optimal growing environment for any playing surface – increasing playability and producing a more enjoyable experience for players and spectators. The system connects to the main drainage collector and moves air through the drainage network utilizing the perforated holes in the pipe to access the soil profile. The main drain collector is intercepted by the system air line. The air line then connects to the system air-water separator. An air-water separator is designed and installed between the field to remove any water from the system.

Hulhumalé is the culmination of the island nation’s efforts to reimagine its focus towards being resilient, economically and With world class infrastructure, Hulhumalé – aims to offer residents, visitors, investors, developers, entrepreneurs and technopreneurs with a global lifestyle. Hulhumalé has been celebrated as a true city for the future, providing them with the perfect platform offering the best solutions to live, work, play and invest. Initiated in 1997, Hulhumalé is the first fully-reclaimed, pre-planned city of the country located within 3 kilometers from Malé, the capital city. Curving a welcoming path for its development in early 2015 Hulhumalé Phase II was reclaimed with the additional 244 hectors. The newly reclaimed addition to the existing conurbation promises diverse development opportunities. Hulhumalé Phase I currently houses 50,000 people with the target population of 80,000 people. With the new developments, Phase II plans a populous of 160,000 people.

Land Transport Management System Reference: HDC- Policy Direction Paper- Land Transport Management System, HUlhumale. 3.1 Background The development of Hulhumale` is one of the most ambitious projects undertaken by the government of Maldives. Hulhumale` Phase 1 which began in 1998 consisted of reclaiming 188 hectares of land to cater for a population of 80,000 which eventually was followed by Phase 2 in 2014 with the reclamation of 240 hectares of land to be developed to cater for an additional population of 160,000. Presently Hulhumale` (Phase 1) is home to some 40,000 people with the targeted combined Population for both phases being 240,000. Hulhumalé is being developed as a modern Smart city with a focus on youth, providing opportunities with the necessary infrastructure to encourage creative entrepreneurship. HULHUMALE’ POPULATION PHASE 1 80,000 PHASE 2 160,000 PHASE 1 & 2 240,000 VISITORS 60,000 TOTAL 300,000 CATEGORY NUMBER OF VEHICLE PERCENTAGE CAR 1850 22 % MOTORBIKE 5563 66 % COMMERCIAL 281 3 % INDUSTRIAL 607 7% PUBLIC 108 2% TOTAL 8409 100% Note: these values are excluding visiting vehicle population from male. The percentage is estimated to be additional 25%.

3.2 ESTIMATED ROAD CARRYING CAPACITY In order to maintain the smooth flow of traffic 10% of road lane length is kept as free space. The remaining 90% is allocated for vehicles according to following ratio.

Existing vehicle ratio in Hulhumale'

Proposed vehicle ratio

Proposed vehicle ratio in Hulhumale Total length of roads (Lane Kilometers) in Hulhumale phase 1 and phase 2 combined is 168 kilometers. Considering each vehicle takes average 1.94 meters of road length (lane meters), 515 vehicles per kilometer is believed to be the maximum carrying capacity for roads. Road length is allocated for these categories according to these lengths.

56

Site Analysis

Following table shows how vehicle quota of Hulhumale will be distributed according to previously mentioned ratios.

Number of vehicle in each category This will result in one vehicle per every three people (1 car per every 70 people and 1 motorbike for every 4 people) in Hulhumale’ these values will be further divided into subcategories. Vehicle quota for each development should be calculated on this basis. Adequate paid/free visitor parking should be provided in each development to cater its users. 3.3 PARKING SYSTEMS

DESIGN INTENT

in Maldives

Design Intent

1. Stadium Design Concept- “ The Reef” The International Cricket Stadium in Hulhumalé will be constructed based on a concept very close to the hearts and minds of all Maldivians, “The Reef”. The Reef is a very clear representation of what it is to be a Maldivian. The Reef is tied to the Maldivian way of life, culture, heritage, food and encompassing love for the Oceans. It also very openly represents the fight against Climate Change. This Façade concept of “The Reef” has been developed based on the initial ideas envisaged by M/s. Arch International in discussion with the Government of Maldives.

The stadium will need to be designed to meet ICC and BCCI standards with the capability of hosting interna-tional cricket tournaments. The design process will follow the best international practices for design and de-livery of world-class sports stadiums. Documents on spectators, teams, official safety, and security will be dis-seminated to all stakeholders for the purpose of seeking thorough consultations on best practices. The design of the stadium will aim to provide spectators with the best experience, i.e. perfect viewing angles, smooth entries and exits. The stadium will also provide State-of-the-Art facilities for players and officials along with spectators. The stadium will be divided in to separate zones that will be secured with appropriate control measures for accessing the stadium. A fence will enclose the outer perimeter of the stadium with clear ‘EXIT’ and ‘ENTRY’ points, designated to handle large crowds. A plan will be established in the future to guide the movement of spectators coming in and out of the stadium. Though seven gates will be constructed for crowd control pur-poses, not all gates will be utilized during all games, unless it is an Emergency. Special ENTRY/EXIT points will be designated for teams, officials, VIPs and VVIPs. Normal spectators will not be allowed to access these special ENTRY/EXIT points. Teams, officials, VIPs and VVIPs will be provided separate ‘Drop-Off’ and ‘Pick-Up’ points. Parking facilities for VIPs and VVIPs will be located close to the VIP lounge and provided for aforementioned persons only. Parking facilities will be kept secure at all times and accessible to authorized persons ONLY. For the purpose of crowd control, no private vehicles, unless provided with special authorization will be al-lowed near or on the stadium premises. All public travel will need to be conducted on public transportation. A location near the stadium will be the designated bus bay, and act as a drop off and pick up point for specta-tors travelling via the bus. Spectators travelling via taxis or personal vehicles will be guided to specific points, from where they will have to walk to the stadium.

60


in Maldives

Design Intent

Adequate diagrammatic signage will be available around and outside the stadium, to make navigation easy for spectators (including disabled persons) and staff members. The aim of the navigational aids is to make locating facilities easier. This stadium will provide special viewing areas accessible to spectators with disabilities. Such areas will have suitable access and evacuations routes, taking into consideration the specific needs of the spectators con-cerned. The provision of adequate viewing standards is important in ensuring that seated accommodation is both safe and serves its intended purpose. Spectators should have a clear, unrestricted view of the whole pitch. Landscaping plays a very important role in creating an invigorating environment. Flora will be selected based on the local climate and soil conditions. A rainwater harvesting and pumping system will be used to water the grass and recharge the underground water. Public Plaza areas are provided which acts as circulation/ gathering areas for spectators, activated by providing retail and sit out areas.

The site required for the construction of this stadium is approximately a 20 acres land parcel, located in Hulhumalé, Maldives.

in Maldives

Design Intent

The Material used for the fins is GRC- Glass Fibre reinforced Concrete. Glass Fibre Reinforced Concrete Glass fiber concretes are mainly used in exterior building façade panels and as architectural precast concrete. The design of glass-fiber-reinforced concrete panels uses a knowledge of its basic properties under tensile, compressive, bending and shear forces, coupled with estimates of behavior under secondary loading effects such as creep, thermal response and moisture movement. Important characteristics of many fiber-reinforced composites are their non-corroding behavior, high damping capacity and low coefficients of thermal expansion. GRC panels, on average, weigh substantially less than pre-cast concrete panels due to their reduced thickness. Their low weight decreases loads superimposed on the building’s structural components making construction of the building frame more economical.

5. Landscape- Podium/ Plaza Areas Landscaping plays a very important role in creating an invigorating environment. Flora will be selected based on the local climate and soil conditions. A master water-tank will be placed at a designated location convenient to groundskeepers, along with a pumping facility that will be used to supply water to various corners of the Complex. A rainwater harvesting and pumping system will be used to water the grass and recharge the underground water.

The Key to a successful execution of high-performance cricket field is the contractor working closely with architects, engineers, contractors, and stadium staff to ensure that the drainage system is compatible along with the sub-surface drainage pipe elevations are suitable for optimum operation, all building spec-ifications norms and codes are met, and all necessary utilities are arranged. Contractor to undertake the supervision of entire construction of sub-base and all the system prerequisites in both, on-site as well as off-site capacity. As and when the project is under execution phase, contractor’s representative can be deputed to super-vise the construction of base periodically and for the installation of the system. In addition, a representa-tive will commission each project by performing field tests and training sessions for members of the con-struction or turf management staff. Cricket Ground Construction: - USGA inspired construction profile - This is the most widely accepted international standard for con-struction of high performance natural grass sports surfaces for not just limited to golf, but also for other professional sports including cricket, soccer, baseball, rugby, etc., and is considered to be a cutting-edge method to construct the modern day stadiums across the world. The methodology of profile design is highly researched and involves detailed checking of all materials and specifications at each stage, to give a fail-safe process for installation. This results in a standardized sub-base construction of the outfield that gives a virtual rain-proofing in terms of drainage, and achieves the highest level of perfor-mance criteria for the playing surface. The design and construction involves the following:

� Drainage system designed for the site conditions based on weather data or a perceived need.

� Sub-surface perforated pipe-based system (linked to the sub surface aeration & Water man-agement system) to give a surface that ensures no standing water while it is raining.

� Irrigation system designed for the site conditions and weather data; automatic, computer-controlled pop-up sprinkler system as is installed at all top cricket grounds world-wide.

The root-zone material will be selected indigenously to satisfy the USGA criteria, and the chosen sand and necessary inclusions analysed at a USGA-certified laboratory.

Cricket Outfield & Infield • USGA concept based material selection • Sand based free-draining rootzone • Perfectly graded, firm, consistent and resilient surface

Construction of a well calibrated cricket pitch is a combination of art as well as science. It is essential for the contractor to be knowledgeable as well as experienced in identifying the right mix of design, material, equipments, skilled manpower to achieve flawless pitches for training as well as competitions. Also work along closely with a qualified curator to create a pitch design that would address the following needs: -

9 Performance requirements

9 Stability and resilience for all formats of the game

9 Can be further customised to achieve the desired output

9 Conform to the national as well as international guidelines

9 Soil/material testing, assessment, and selection also considering permeability and drainage as-

pects

9 Well balanced nutrient content and turfing as required

9 Easy to prepare for the season and to maintain post season

Drainage Design

After years of research, cricket fields are now constructed with the most optimum sub-surface drainage solution for the cricket fields to sustain low/moderate/variable/extreme climatic conditions. All the way from desert-like arid regions to the typical humid, sub-tropical regions, every project has it’s own specific drainage requirement based on the project location. This is a primary factor considered by the field de-signers as a common practice. However, this factor alone cannot determine the drainage design and planning. Regardless of the project location, the game of cricket though, demands a firm and relatively dry play surface during every match. It has great bearing on the surface-ball interaction as well as player perfor-mance. Cricket fields around the world that do not have an efficient subsurface drainage system are also known to have suffered multiple game cancellations or delays. This is exactly where a good drainage de-sign and planning comes into play. This not only provides huge assurance to the stadium owners but also a flexibility to schedule matches at any time of the year. The drainage designs and specifications are derived from knowledge base, best practice methods and proven track record from various grass-based sports facilities previously developed and inspired by the guidelines laid down by entities such as USGA, AASHTO, ASTM, EN, IS standards. The pipe material – DWC and its perforation patterns conform to AASHTO specifications. Volumetric calibrations along with specif-ic design layout determine factors such as area coverage, spacing, outfall, nature of sub-base, diameter requirement to achieve optimum drainage along with other factors.

Drainage Design • Network of sub-surface DWC perforated drainage pipes • Closed-loop system with 150mm to 900mm pipes • Single point discharge with efficient water harvesting

Activating the vacuum mode allows the turf manager to remove standing water in a short amount of time, remove non-capillary water from the soil profile, and introduce fresh air into the root zone. The vacuum mode is used to remove standing water during games or other events. As a daily practice, the vacuum mode fosters a healthier growing medium for the plant's roots, helping to establish stronger roots and stronger turf.

Delay in match due to wet outfields… Soggy outfield causes injuries to players...

Sounds familiar?

One of the greatest joys on a cricket or football ground is an uninterrupted match on a lush green outfield. With extensive diving, sliding and the need for a predictable ball bounce, it is a MUST to have a flawless

outfield. But when it rains before or during the match, you are almost resigned to delaying or in worst cases even cancelling the match which has become a common phenomenon…until now!

Today’s standard of game demand an absolutely perfect grass quality in the outfield due to:

9 Extensive sliding and diving during fielding. 9 Even, predictable bounce for more effective fielding.

9 Temperature moderation (cooling) of the grass due to many hours of fielding.

During rains, only the wicket area is covered, leaving the outfield wet. When rain subsides spectators & TV audiences demand immediate resumption of play. Apart from this, significant financial losses occur due to

the high cost: o TV & Internet rights o Insurance premiums o Gate collections

o In-stadia advertisement o Administration costs (organizers, players, officials etc).

The system can also apply pressure to force air from the subsoil pipes through the soil profile. This technology creates air movement that provides aeration while moderating temperature in the root zone.

Deeper and stronger root system. Stadium Utilization: Multi-sport & multi-purpose.

Activating the pressure mode enables the turf manager to inject fresh air into the soil profile during stressful events or extreme temperatures, hot or cold. Turf managers use the pressure mode to constantly inject fresh

air into the profile during concerts or other events requiring temporary covering of the turf surface. As in any sport, cricket and football fields require the best possible quality of sports turf and more

importantly, maintained at the highest standards. However, this is easier said than done. By nature of how grass grows, it is common to have brown patches, uneven density, thatch, black layers and very prone to

various diseases. In fact, very high or low moisture, temperature, humidity etc., also are very detrimental to the growth of perfect sports turf.

The lush green outfields are not easy to maintain due to problems like black layer, thatch, brown patches,

uneven density and various turf diseases. In fact, very high or low levels of moisture, humidity and temperature can also destroy good turf.

Contractor to help assess the requirement of necessary surface treatment prior to turf installation. A fu-migation or suitable weed and/or termite control treatment is carried out on need basis to ensure that the base and rootzone is completely free of undesired elements. Further on, installation of the selected turf grass is carried out using the pre-determined method. While seeding or ‘sprigging’ are the most widely adopted methods of planting turf grass, in certain cases, pieces of cultivated sod is used for a relatively quick establishment of the turf surface. This, however large-ly depends on the availability of required turf grown at a nursery located within close proximity to the site location. In case of seeding, purchase of the seeds from a reputable supplier and a certified pedigree varie-ty of seeds, is highly desirable. In case of sprigging, we would typically deploy several quality control measures to ensure that the sprigs are harvested in a systematic manner and are free from weeds or other contaminants. It is also desirable that the location of the turf nursery is within a close proximity of the site location and is harvested, cleaned, transported, checked and planted at site speedily.

Turfing/Grassing

in Maldives

Field of Play

Hybrid Turf Reinforcement The concept of Hybrid turf began in the 80’s aimed to provide the ad-vantages and comfort of natural grass turf along with the durability and flex-ibility of synthetic turf for training and competition grounds. Artificial turf fibres are injected or ‘stitched’ withinthe rootzone area of a playfield to provide strength and reinforcement to the natural grass roots. The concept of Hybrid turf in cricket is the most cutting-edge solution which has been developed after several years of R&D aimed to address specific challenges related to the management of turf to world-class standards. 9�High-class playing surface of natural grass 9�Creates healthier and deeper grass plant root sys-tem 9�Rootzone is reinforced/ structured 9�Faster recovery of playing surface 9�Optimal drainage capacity 9�Offers additional hours of play per season 9�Consistent playing characteristics guaranteed in all weather conditions 9�Players acquire grip and control and can trust the performance of the surface

TURF PROTECTION SYSTEM

Turf protection tiles are manufactured from Natural virgin translucent high-density polyethylene which not only gives a product far superior in strength to any of its competitors, it also allows the light to go through the translucent material, therefore allowing photosynthesis to continue. The translucent material also has another huge benefit in that it allows the sunlight to penetrate the tile and draws moisture from the ground, forming a moisture canopy on the underside of the tile. When the sun goes in this moisture condenses and drops back to the ground thus recycling the required water to keep the grass healthy. The turf does not therefore require watering during the period it is covered.

144

FOR VEHICULAR TRAFFIC

The tile is specifically designed for use in Stadiums & large Arenas during concert load-in and load-out. For years Promoters had been looking for the product that would enable them to bring 150 tonne cranes, forklifts and trucks onto the stadium field without causing significant damage. In the past they have used plywood or aluminum panels, with disastrous effect.

The tile which can be laid by hand and is manufactured from translucent high-density polyethylene plastic, incorporating a unique internal ribbing system with neoprene seal that makes it incredibly strong whilst allowing the grass to continue growing normally. The tile utilizes a specially designed bolting system to join the tiles into blocks of 2 prior to leaving the factory. This creates a usable panel area of 2.1m x 1.1m with integrated 10cm overlap incorporating locator bosses for easy fitting, together with an expansion joint.

Each panel of 2 x tiles joins to its adjacent blocks using a special 2-part vertical looking cam that are locked using a long-handled T-Bar.

Turf protection tiles are Manufactured from Translucent Virgin High Density Polyethylene (HDPE), that is not only very strong, it also allows sufficient light to pass through to ensure continuous photosynthesis – a MUST for the ultimate protection of the grass!

It incorporates an integral anti-slip top surface with specially designed, raised air holes that allow the turf to breathe but at the same time prevent liquids from penetrating to the turf below.

It has radiussed webbing for maximum strength & patented round feet that lift the tile slightly from the turf thus minimising any ‘cutting’ of the turf.

It has an overlap which, when combined with the factory fitted pins and the locking cams delivers expansion/contraction capability whilst preventing rubbish & non-desirable liquids from passing through to the turf – whether natural or artificial.

These products are all specifically designed for use in stadiums and arenas to protect their quality turf, so that venues can host vital revenue-generating non-core events. They have borne quality systems that allow facilities to accommodate high profile concerts and other events in quick succession with sporting fixtures, secure in the knowledge that their playing surface is not at risk.

Strategically designed for the protection of ‘quality natu-ral turf’ when continuous photosynthesis and air circula-tion are required. This ensures good grass colour and health, when covered for a number of days for non-sporting events. The top surface has an integrated very efficient anti-slip pattern. The slightly embossed design provides small channels to keep any spilt liquids away from the patrons feet, whilst being shallow enough not to be a trip hazard. Each panel of 4 tiles connects to its adjacent panels by means of patented vertical camlock and bolt systems, which are manufactured from special nylon that is as strong as steel.

Each tile incorporates a 100mm (4 inch) overlap, which is a very effective barrier that stops liquids from penetrating to the turf. This overlap also includes strategically designed ‘location bosses’ that make alignment of tiles for fitting and locking together really simple. Additionally, they act as stabilisers to resist the tiles twisting under duress.

The innovative circular ribbing geometry of combines strength with light weight. The specially designed ribs and patented feet spread the load evenly and any ‘impressions’ on lifting disappear after a short time, or during cutting. This strategically constructed underside provides 33mm ‘head room’ allowing the grass blades to stand erect, preventing excessive stress. It is fitted with 25 x patented circular feet that extend 10mm from the underside of the tile to create an air flow, which reduces disease.

These products are all specifically designed for use in stadiums and arenas to protect their quality turf, so that venues can host vital revenue-generating non-core events. Two people lay a panel of 4 tiles at one time, covering 4.84m² (52ft²). This results in the fastest laying times of any product, which is reflected in substantially reduced labour costs and turnaround times.

SUB SURFACE DRAINAGE AND VACUUM POWERED

SYSTEM The System provides stadium and playing field owners and their caretakers the ability to promote healthier, stronger, and safer turf by accelerating moisture removal and increasing the amount of oxygen to the root zone. As a result, the system helps provide an optimal growing environment for any playing surface – increasing playability and producing a more enjoyable experience for players and spectators.

The system connects to the main drainage collector and moves air through the drainage network utilizing the perforated holes in the pipe to access the soil profile. The main drain collector is intercepted by the system air line. The air line then connects to the system air-water separator. An air-water separator is designed and installed between the field and the SubAir to remove any water from the system.

An “Air-Water chamber” is the convergence point, wherein an “air-water separator” redirects the water to the storm water sewers or to the rain water harvesting tank; and the air is expelled out by the reversing valve of the System.

Field of Play

VACUUM & PRESSURE MODES OF THE SYSTEM

Activating the vacuum mode allows the turf manager to remove standing water in a short amount of time, remove non-capillary water from the soil profile, and introduce fresh air into the root zone. The vacuum mode is used to remove standing water during games or other events. As a daily practice, the vacuum mode fosters a healthier growing medium for the plant's roots, helping to establish stronger roots and stronger turf.

Activating the pressure mode enables the turf manager to inject fresh air into the soil profile during stressful events or extreme temperatures, hot or cold. Turf managers who use the system utilize the pressure mode to constantly inject fresh air into the profile during concerts or other events requiring temporary covering of the turf surface.

Field of Play

The system is automated based on data received from the field through the Turf monitoring and control system. The system receives and reports soil data (salinity, moisture, and temperature) via wireless sensors placed at critical positions within the soil profile throughout the field. The data then prompts the system to perform according to the levels and parameters set by the turf manager. Every operation of the system is fully automated and accessible through any internet connection or wireless device. System Control Interface Measure temperature, salinity & moisture at two depths per sensor location. Data is transmitted via radio to the turf manager’s office. Provides alarms & alert when parameters are exceeded. Can be remotely monitored and controlled from internet or mobile.

SUSTAINABILITY

in Maldives

Project Scope Sustainability

1. INTRODUCTION BREEAM (Building Research Establishment Environmental Assessment Method) is a sustainability assessment method that is used to masterplan projects, infrastructure and buildings. Launched in 1990, by the Building Research Establishment (BRE) it sets standards for the environmental performance of buildings. Aims of BREEAM is to mitigate the life cycle impacts of buildings on the environment to enable buildings to be recognized according to their environmental benefits to provide a credible, environmental label for buildings to stimulate demand and create value for sustainable buildings, building products and supply chains.

2. Objectives of BREEAM

� To provide market recognition of buildings with a low environmental impact � To ensure best environmental practice is incorporated in the planning, design, construction and

operation of buildings and the wider built environment � To define a robust, cost effective performance standard surpassing that required by regulations � To challenge the market to provide innovative, cost effective solutions that minimize the

environmental impact of buildings � To raise awareness among owners, occupants, designers and operators of the benefits and value of

buildings with a reduced life cycle impact on the environment � To allow organizations to demonstrate progress towards corporate environmental objectives

BREEAM assessment evaluates the procurement, design, construction and operation of a development against a range of targets based on performance benchmarks. It focuses on sustainable value across range of categories:

206


in Maldives


BREEAM measures sustainable value in a series of categories, ranging from energy to ecology. Each of these categories addresses the most influential factors, including low impact design and carbon emissions reduction; design durability and resilience; adaption to climate change; and ecological val-ue and biodiversity protection. Independent licensed assessors carry out an assessment of a scheme and each of the criteria is scored and then multiplied by a weighting.

3. BREEAM Rating Benchmarks There are a number of elements that determine the overall performance of a project assessed using BREEAM; This is followed by a description and methodology for calculating a BREEAM rating benchmarks: Table 1: BREEAM rating benchmarks

BREEAM RATING % SCORE

OUTSTANDING ≥ 85

EXCELLENT ≥ 70

VERY GOOD ≥ 55

GOOD ≥ 45

PASS ≥ 30

UNCLASSIFIED < 30

207


in Maldives


4. BREEAM New Construction Scheme Timing the engagement with and use of the BREEAM New Construction scheme via the BREEAM Assessor is essential for ensuring seamless integration of the methodology in the new-build procurement process. With-out this, the ability to optimize cost-effectively the building's environmental performance and achieve the desired BREEAM rating will be compromised. Appointing a BREEAM Assessor or Accredited Professional early in the project will help in achieving the target rating without undue impacts on the flexibility of design decisions, budgets and potential solutions. Clients can view up-to-date listings of licensed BREEAM New Construction Assessors and BREEAM Accredited Professionals on BREEAM projects:www.breeam.com/projects. It is important to recognize that BREEAM primarily reflects the overall performance of the building rather than just the opportunities or limitations placed on specific stakeholders involved in the procurement process. This means that the client, design team, principal contractor and BREEAM Assessor, as well as other specialist disciplines, have an important role to play throughout the procurement process, if the desired performance level is to be achieved and reflected through the certified BREEAM rating. The onus of orientating the brief towards sustainability needs to come first and foremost from the client. To facilitate this, BRE Global recommends that clients and their project teams engage with a BREEAM Assessor or BREEAM Accredited Professional no later than the Preparation and Brief stage. This will ensure that realis-tic targets are set and can be met, appropriate responsibilities can be defined and understood, and low or no cost solutions to environmental impacts can be sought and applied wherever possible.

This BREEAM scheme document is a technical document which has been created to:

� Enable qualified and licensed BREEAM Assessors to complete BREEAM assessments and determine a rating

� Enable BRE Global Ltd. to complete quality assurance reviews of a BREEAM Assessor's assessment report, in accordance with the standards to which BRE Global Ltd. is accredited

� Act as an aid for BREEAM Accredited Professionals (AP) to undertake project team facilitation, in terms of defining, monitoring and successfully achieving the desired BREEAM rating

� Act as a reference for clients and members of the project team whose proposed building is being BREEAM assessed.

The scheme document is split into following parts:

1. Introduction to BREEAM 2. Scope of the BREEAM International New Construction 2016 scheme 3. BREEAM rating benchmarks 4. The BREEAM evidential requirements 5. Assessment criteria

The Scope section describes the types of buildings and stages of assessment that this BREEAM Scheme can be applied to. The Scope section can be used by clients and BREEAM Assessors to check whether this is the correct BREEAM Scheme to use for their project. The Scoring and rating section illustrates how a building's assessed performance is measured and rated. It outlines the BREEAM rating level benchmarks, the minimum BREEAM standards for each rating level and the BREEAM environmental section weightings. It also includes a description of the BREEAM assessment issues and 'credits', including BREEAM 'innovation credits', and how performance against these is calculated and expressed as a BREEAM rating. The BREEAM evidential requirements section provides guidance to assessors and project teams on the vari-ous types and forms of evidence required by the BREEAM Assessor to demonstrate compliance with BREEAM criteria. This includes a description of why BREEAM requires an auditable trail of evidence. The Assessment criteria section includes the individual BREEAM assessment issues, categorized in 10 environmental sections. Each issue defines a level of performance against which the assessed building demonstrates compliance in order to achieve a corresponding number of available BREEAM credits. The majority of BREEAM issues and credits are tradable, a project team can pick and choose which to target in order to build their BREEAM performance score and achieve the desired BREEAM rating. Several BREEAM issues have minimum standards, meaning that to achieve a particular BREEAM rating specific credits must be achieved.

210


in Maldives


5. BREEAM Minimum Standards To maintain a flexible system BREEAM adopts a 'balanced scorecard' approach to the assessment and rating of a project. This means that to achieve a particular level of performance the majority of BREEAM credits can be traded, i.e. non-compliance in one area can be offset through compliance in another to achieve the target BREEAM rating. It is important to bear in mind that these are minimum acceptable levels of performance and in that respect they should not necessarily be viewed as levels that are representative of best practice for a BREEAM rating level. To achieve a particular BREEAM rating, the minimum overall percentage score must be achieved and the minimum standards, detailed in Table 2 applicable to that rating level complied with.

8.10 INNOVATION

BREEAM is rewarding buildings that go beyond best practice in terms of a particular aspect of sustainability, i.e. where the building or its procurement has demonstrated innovation. Awarding credits for innovation en-ables clients and design teams to boost their building’s BREEAM performance and, in addition, helps to sup-port the market for new innovative technologies, and design or construction practices. There are two ways in which BREEAM awards ‘Innovation Credits’ to recognize innovation in building design and procurement. The first is by meeting exemplary performance criteria defined within an existing BREEAM issue, i.e. going beyond the standard BREEAM assessment criteria and therefore best practice. The second route is where an application is made to BRE Global by the registered project’s BREEAM Assessor to have a particular building technology or feature, design or construction method or process recognized as Innovative. If the application is successful and subsequently compliance is verified, an ‘innovation credit’ can be awarded. An additional 1% can be added to a building’s overall score for each innovation credit achieved. The maximum available additional score for ‘Innovation’ is 10%. The building's final BREEAM score will be capped at 100%. Innovation credits can be awarded regardless of the building’s final BREEAM rating.

10. AWARDING BREEAM CREDITS Each category is sub-divided into a range of assessment issues, each with its own aim, target and bench-marks. When a target or benchmark is reached, as determined by the BREEAM assessor, the development or asset score points, called credits. The category score is then calculated according to the number of credits achieved and its category weighting. Once the development has been fully assessed, the final performance rating is determined by the sum of the weighted category scores. Two assessment stages are carried out a design stage assessment which results in an interim certificate, and a post-construction assessment resulting in a final certificate being issued and a rating awarded. The BREEAM rating benchmark levels enable a client or other stakeholder to compare an individual building’s performance with other BREEAM rated buildings and the typical sustainability performance.

3.8 SERVICEABILITY DESIGN:-

The limit states of Deflection and Vibration are studied and discussed in this section.

3.8.1 DEFLECTION:- The overall structure and its components tend to have some deflections and or movements when

subjected to lateral loads. This need to be studied and checked against the allowable tolerances, for

which there will not be any problems regarding strength or perception related issues.

The movements can be caused by gravity and lateral loads, long term creep and shrinkage effects,

temperature stresses etc.

The table below gives the global as well as local limits on the deflections, set out by the British

239

Element Deflections Clause 2.5.2 BS 5950-1-2000 (For steel members)

Cantilevers L/180

Beams carrying plaster L/360

Other beams L/200

Care has taken to ensure that for all the structural elements, the deflection values are well within the

above limits.

3.8.2 VIBRATIONS:-

Floor vibrations generally make people uneasy and create concerns of structural distress. The highest

vibrations are likely to arise from resonant response due to repeated footfalls at a frequency that is

either the same or a multiple of the natural frequency of the floor. To provide the necessary vibration

control, the structural floor system requires to be relatively rigid and of sufficient mass to reduce the

acceleration.

The following limits have to be followed:

Structure

Anchoring and stabilizing devices The squaring up of frames and risers will be done through the use of braces.

Assembly is done thanks to pre-fabricated self-locking elements which fit into each other. This ensures the utmost security during assembly (no need for screws or bolts). Moreover, braces allow for the squaring up of frames and risers between each walkway, which then ensures the stability of the grandstand lengthwise.

Jacks Anchoring on the ground will be ensured by adjustable jacks (which also allows for levelling off the grandstand in case it is erected on uneven ground, outdoors for instance). On concrete foundation works (slabs, posts or beams), anchoring on the ground will be done on each plate using a 10 x 80, Spit NYL 12 type or related type, anchoring screw.

4.0 Roof Structure- Tensile Roof

Emblematic buildings

The light weight and flexibility of composite membranes offer tremendous freedom of shape for the creation of emblematic buildings. Tensioned roofs are ideal for large span roofs, allowing the transmission of natural light to ensure a pleasant luminous atmosphere.

Solutions for open and closed buildings

Membranes enable the installation of tensile roofs on open structures for sports activities (stadiums, grandstand roofs, etc.), cultural buildings (amphitheaters, etc.) and educational establishments (covered playgrounds for schools, etc.). They enable the creation of roofs or entire envelopes for closed buildings to optimize the transmission of natural light into atriums, shopping malls, sports halls and arenas, airport terminals and stations, etc. They also allow for the implementation of double skin thermal insulation solutions.

1. HVAC SYSTEM

1.1. Purpose:

The Section outlines HVAC system design parameters, system selections and extent of provisions for the project. The air conditioning will be designed to maintain specified temperature, humidity and supply of outdoor air within occupied spaces. All Air conditioning & Ventilation systems shall be in conformity with the ASHRAE 62.1-2017 for following purpose:

¾ To create a comfortable and safe HVAC environment for the development is a Prime

objective. ¾ To maintain good indoor environment in terms of temperature, humidity and Air

movement & Air Quality. ¾ To create a relatively quiet and low vibration control AC system. ¾ To make the HVAC system energy efficient eco-friendly & easily maintainable.

1.2. Design Strategy & Criteria: -

Relevant Standards:

¾ Indoor Air Quality as per ASHRAE 62.1-2016 ¾ ANSI/ASHRAE/IESNA standard 90.1-2016: Energy standard for buildings ¾ Duct construction standards as per relevant IS Codes and SMACNA ¾ Air filters as per ASHRAE 52.1-1992 and 52.2-2017 ¾ ASHRAE Standard 55: Thermal comfort

1.3. Basis of Design:

1.3.1 Ambient Conditions

a) Outside Condition 31.6qC Dry Bulb (88.88° F DB)

26.8qC Wet Bulb (80.24° F WB)

b) Inside Conditions 23.33qC Dry Bulb (74° F DB)

MEP 1.3.2 Building data Assumptions:

Building construction data proposed are as follows:

All outer walls: U = 0.36 Btu / HrSq.Ft °F

Roof U = 0.32 Btu / HrSq.Ft °F

Floor U = 0.32 Btu / HrSq.Ft °F

Glass Specifications SHGC 0. 44 U Value = 0.56 Btu/ Hr. Sq. Ft °F

Note: Above design envelop values are assumed for heat load calculation. Glass specification has been assumed due to non-availability of Data. 1.4. LOAD SUMMARY:

Based on the architectural drawings and above considerations we have calculated the air conditioning load floor vise as follows:

Detailed Heat Load Summary Floor Wise: -

The Floor Wise Heat Load Summarize as Follows: -

Merits:

1. VRF system provides superior comfort, energy efficiency, easy design, easy installation & maintenance.

2. Choice of designer indoor units: Different IDU options can be used like Hi-wall unit, cassette unit, concealed unit, ducted, floor mounted, TFA unit and so on. This can help in blending the air conditioning system with the appropriate interior design of the space.

3. Operation is very simple, probably as simple as operating a split air conditioning system and hence no separate manpower is required for operating the system.

4. Individual control for cabin. 5. Use of minimal outdoor units ensures that valuable space is saved. 6. Saving on electricity bills. 7. Compatibility with BMS system. 8. Compatibility with AHU. 9. Minimal noise & vibration. 10. Refrigerant used (R410A) is eco-friendly. 11. Operates in extreme ambient temperature.

The VRF equipment can be switched ON/OFF by end users themselves from their respective locations using simple controllers. The VRF system also has the optional facility to provide a centralized control in addition to operation and control by individual controllers. Such centralized control system can be operated from a convenient location in the Building.

Indoor Units shall be connected to (64.0Tr or 80 HP) with multiple VRF Outdoor Unit for Indoor Swimming pool area, Individual ODU unit capacity will be finalized in detail design stage.

2.9 LIGHTENING PROTECTION:

Conventional LPS as per IEC 62305-3 is proposed to protect building from lightning strikes.

This part of IEC 62305 deals with the protection, in and around a structure, against physical damage and injury to living beings due to touch and step voltages.

The main and most effective measure for protection of structures against physical damage is considered to be the lightning protection system (LPS). It usually consists of both external and internal lightning protection systems. An external LPS is intended to

x Intercept a lightning flash to the structure (with an air-termination system), x Conduct the lightning current safely towards earth (using a down-conductor system), x Disperse the lightning current into the earth (using an earth-termination system).

An internal LPS prevents dangerous sparking within the structure using either equipotential bonding or a separation distance (and hence electrical insulation) between the external LPS components and other electrically conducting elements internal to the structure. Main protection measures against injury to living beings due to touch and step voltages are intended to:

x Reduce the dangerous current flowing through bodies by insulating exposed conductive parts, and/or by increasing the surface soil resistivity,

x Reduce the occurrence of dangerous touch and step voltages by physical restrictions and/or warning notices. The Vertical air terminal is located at edge or highest point of staircase head room. Number of earth pits considered are as per Type B Earthing System.

Ring earthing to be installed at the depth of 1 meter from the protected structure and laid at the depth of 0.5 meters around the building periphery.

Following are the parts of Conventional Lightning Protection System. x Grid of horizontal conductor above the roof.

x Down Conductors.

x Joints & connectors.

x Testing Joints.

x Earth Termination Network (Peripheral grid around the warehouse building of earth ground conductor).

In this system, water supply will be catered by hydro pneumatic system with uniform residual head of 1.5 kg/cm2- 2.1 kg /cm2 at every fixture at topmost level. No OHT requires for domestic & flushing water except fire requirement. Water distribution for domestic water supply for the building has been proposed based on the Buildings and height of the same. It shall be ensured that Pressure reducing valves (PRV) are provided (if required) to limit water distribution pressure to 1.5 – 4.5 Kg/cm². The distribution system will be designed considering domestic & flushing water requirement of units on each floor, frictional losses, static head available and residual head required. Hydraulic design involves optimizing the suitable diameter to get residual pressure at tap point with head loss in transit and static head due to height of building. The pipe sizing shall be based on fixture unit calculation as per ASPE standard. The pipe size of riser shall be restricted to nearest 4” size to optimize on capital cost, and for ease of installation and maintenance. However, the maximum velocity in the water supply piping shall not exceed 2.4 m/second.

Water meters shall be provided in individual commercial shop and stadium area for water consumption recording for efficient monitoring and assessment. Head losses through water meter shall be accounted for in water distributions calculations.

Process Description

In order to conserve water, sewage treatment plant shall be designed to ensure that treated effluent (water) characteristics are well below the permissible limits, even under varying flow conditions which are typical for such systems. This implies that the selected process shall be able to withstand shock load situations.

MBBR type STP has following advantages:

x The process has long retention time and can absorb shock load situation.x The process produces a well oxidized sludge in small quantities only, which can

be discharged to municipal tankers by sludge transfer pump.

The sewage treatment plant shall be designed for a capacity to handle soil and waste water from the sports complex. Soil & Waste water from the sports complex shall flow into a grit chamber to remove settling grit. Waste water from the toilets, showers etc. shall flow into STP. A bar screen shall be provided at the inlet point in the sump and the waste water will flow through this bar screen into the sump.

NOTE : In order to achieve BOD level of less than 5 Mg/L, Ultrafiltration Membrane System shall be installed after Tertiary Filtration.(If applicable)

The bar screen shall be so designed that it can be cleaned manually from the top of the sump. Two submersible solid handling pumps shall be provided in the sump to pump the collected waste water from equalisation tank to the aeration chamber. Equalisation Tank shall be designed for 16 hrs retention. These pumps shall have the capability to handle effluent with solids upto 40 mm size.. Automatic level controller shall be provided in the sump to turn the pump off at the low water level in the sump and to automatically start the pump when water level is high. In case the water level in the

320


in Maldives

MEP sump continues to increase (pump out of order), the stand by pump will start and high level alarm shall come on, indicating pump

problem. Submerged air diffusers shall also be provided in the sump to keep the suspended solids in suspension and to prevent the sewage from turning septic.

Waste water from the flow Aeration Tank shall flow into the moving bed Bio reactor tank, where it shall be mixed with activated sludge (Mixed Liquor Suspended Solids).

From the MBBR tank, this mixed liquid shall pass into the secondary clarifier. Through the use of baffles the liquid in the clarified tank shall be maintained in a quiescent condition which shall allow the solids to settle to the bottom for collection. The accumulating solids known as “Sludge” shall be constantly pumped from the clarifier tank bottom to the MBBR tank. This return sludge shall undergo further digestion in the MBBR tank and shall also provide the active organisms needed to digest the incoming raw sewage.

A skimmer system shall be provided at the surface of the secondary classifier to continuously skim the surface and to pump the skimming back into MBBR tank. The `clarifier shall also have an adjustable overflow weir to collect the treated effluent and a scum baffle shall keep any floating matter from passing out with the final treated water.

Treated water from the secondary clarifier shall over flow into adjoining mixing tank where alum shall be added. Mixing shall be provided by air diffusion. From the mixing tank water shall flow by gravity into an adjoining baffled treated water tank shall have volume sufficient to store treated waste water for one day storage.

The Treated water from the source Filtration system shall be collected in a tank near the Ultra filtration System. The water shall be pumped for further treatment.

Ultra Filtration Block:(If Applicable)

We have included an Ultra filtration block in the system. The treated water after passing through the micron filter is passed through the Ultra filtration (Hollow Fine Fibre) block. The UF removes all the suspended matter & organics. Ultra filtration provides macro-molecular separation of particles in the range of 20-1000 Angstrom (up to 0.1 micron) like bacteria, viruses, proteins and large organic molecules, colloidal and particulate matter. High permeability i.e. molecular weight cut-offs of the ultra-filtration membranes and negligible osmotic effects allow the ultra-filtration process operates at relatively at low pressures (1 to 3 bars).

The treated water then stored and reused as makeup water for flushing and for external horticulture. Excess sludge from the bottom of the clarifier shall be passed into an adjoining aerobic digester cum thickener tank. In this tank, sludge shall be aerated. Air shall be shut off periodically and separated water shall be pumped back into the MBBR tank. This way the sludge shall be thickened and its volume reduced. The sludge digester cum thickener tank shall be sized to hold excess sludge production of at least three months Submersible solids handling pump with flexible hose connection shall be supplied to pump the sludge out into municipal tanker on required basis. Filter press shall be provided for sludge treatment.

4.10 Solid Waste Management :

Waste Characterization

Characteristics of waste refers to those physical and chemical properties that are relevant during collection, storage, treatment and disposal of waste such as density, moisture content, calorific value and chemical composition. In order to plan, design and operate a solid waste management system, a thorough knowledge of the quantity of waste generated as well as their composition and characteristics are essential.

Understanding the physical and chemical properties of waste is the cornerstone upon which subsequent steps of waste management is decided. It is necessary for gauging what risks a waste might pose to surface water, ground water, and air and helps in waste management unit design. A waste characterization begins with an understanding of the various sources that generate waste. Each source will have different characteristics of waste. With the objectives of maximum recovery of useful material and optimisation of waste recycling, the waste expected to be generated in Stadium Project is broadly classified into the following categories:

x Biodegradable waste x Recyclable waste x Miscellaneous waste

Biodegradable waste

The biodegradable waste includes food waste, fruits & vegetable waste, paper & pulp, paper admixture with food waste. Biodegradable waste constitutes high organic matter and is easily decomposable. The primary elemental composition of biodegradable waste comprise of carbon,

322


in Maldives MEP oxygen, hydrogen, nitrogen etc. This acts as a substrate for micro-

organism to decompose into simpler substances like methane, organic acids, amino acids etc.

Recyclable waste

Recyclable material includes paper, plastic, glass & metals. Paper material includes cardboard, paper grocery bags, fast food bags, department store bags, newspaper, office papers, photocopy and letter paper, paper used in offices. Glass material includes beverage and food containers of fruit juice bottles, peanut butter jars, mayonnaise jars, whole or broken soda, safety glass, and architectural glass are included in this category.

Metal includes tin/steel cans like canned food and beverage containers, non-ferrous metals like clothes hangers, metal pipes, stainless steel cookware, security bars, soda cans; scrap ferrous items and aluminum foil are also included in this category. Plastic includes plastic containers including HDPE containers like milk jugs, water jugs, detergent bottles, toiletries bottles, empty motor oil, empty antifreeze, and other empty vehicle and equipment fluid containers, PETE Containers like soft drink and water bottles, cooking oil containers, plastic food containers such as bottles for salad dressings and vegetable oils, flexible and brittle yogurt cups, syrup bottles, margarine tubs, microwave food trays, clamshell-shaped fast food or muffin containers, and foam egg cartons. Film plastic like plastic garbage bags, food bags, dry cleaning bags, grocery store bags, packaging wrap, and food wrap. Plastic items mainly include auto parts made of plastic attached to metal, plastic bubble packaging, drinking straws, foam drinking cups, produce trays, foam packing blocks, packing plastic, foam plates and bowls, plastic strapping, plastic lids, plastic bottles and new plastic laminate.

Solid waste generation from proposed Stadium:

Currently the per capita generation of solid waste is 0.1 – 0.25 kg/person/day from Commercial and Stadium premises.
