Introduction about Project
The Vinh Luong FishingPort project is in Vinh Luong commune, Nha
TrangCity. This project was built Nha Trang city at first phase in
2006 with 8 billion VND. The port is assigned to PPP and the
Department of Agriculture and Rural Development to manage. However,
the active capacity of port is not enough with the activities of
ships. ‘On the peak, the port welcomed 36 of vessels; catches are more than 150 tons of
seafood. However, the length of pier only is 100 meters, width of 9m, each in turn, the port
can only allow about 10-15 ships dock’. The pollution of fishing port impacts
to environment in activity process. To stop these problems above, the
Nha Trang PPP has decided to upgrade the fishing port. The Department
of Agriculture and Rural Development is owner, the cost is about 25
billion VND (1.2 million USD), and the capital is supported by the
World Bank and the province. (Vietnamplus)

1. Describe the current trends in fishing port project procurement
There are many kinds of current trends in construction industry.
However, for this project we will draw up two main types of current
trends. The first of all current trend is Engineering Procurement
Construction and second is Public Private Partnership.To select the
most suitable procurement method to the Vinh luong fishing Project we
will analyze and evaluate two current trend to give the most suitable
current trend.
1.1 EPC
EPC (engineering procurement construction) contract.
Figure 2: Diagram of EPCSource: Developed for this report
Engineering, Procurement and Construction (EPC) contracts are the most
common form of contract used to undertake construction works by the private
sector on large-scale and complex infrastructure projects such as Dung Quat
Oil Refinery project. In this contract, the main contractor performs all
works of project such as the technical design consultant or construction
drawing; supply of materials and equipment for construction; construction
and handover to client.

The Public Private Partnership (PPP) current trend is a business
relationship between private company and government agency for
purpose of completing a project to serve the public. In the PPP
current trend, the private sector is responsible over finance,
design, and building, maintaining, and operating the project which is
traditionally provided by public sector.
Traditional Method: the government borrows money from public or tax.
After that, the government pays to get infrastructure such as roads,
highways…etc. The people are going to use free.
PPP Method: the private companies borrow money to build
infrastructure such as roads, highway, and railways. Then the public
pays the cost to use the infrastructure. When the private company
takes back enough the cost that they used to built, they will
handover the infrastructures to government. After that, the
government stipulates for this project periods of time.
The characteristics of PPP such as an innovated solution for delivery
of public services, the efficiency, quality and management of project
are increased, the risks are transferred to the private company,
especially the value for invested money this mean is the amount of
money is lost as public sector.
Five Main Kinds of Public Private Partnership Current Trend
Design and Build

The private company designs and builds infrastructure following to
the the public sectors performance specifications. The private
companies are paid by the public sector with a fixed price. The
contract is called as the “turnkey’ contract.

Build and Transfer
The private company designs and builds a project, and then the
project will be given to government. The government will control it.
Build-Transfer-Operate
The private sector designs and builds a project and the project is
transferred to the government. The Government authority controls the
project.

1.3 Selecting the most suitable current trend for fishing port
In my opinion, for this project the client (Department of
Agricultural and Rural Development) should select the PPP (Public
Private Partnership) current trend and more specific in here that is
Design-Built method. I choose this current trend by some reasons
related to project such as the cost of project has to be prepared
sufficiently from World Bank;the fishing port is still acting daily.
So the project has to be completed in short time as possible.
Especially, the quality will be improved with using this contract
(Vietnam plus, Nationaltimes)
1.4 The hired subcontractor
As we have known, in a construction project has many works undertaken
by many subcontractors such as design, foundation, and concrete
placing subcontractors. In my opinion, the main contractor should
DO PHI HUNG 12 CM
8
8ASSIGNMENT
hire a port design subcontractor. For example, the PORTCOAST
CONSULTANT CORPORATION, which has much experience in port consulting
and designing. The main contractor can use the JCT Nominated
subcontract for the subcontractor (Allan Asworth). With the
contracting the subcontractor, which helps the main contractor deals
with the problem of time of project.
1.5 Conclusion
In summary, for the Vinh Luong fishing port, the PPP (Public Private
Partnership) current trend is the most suitable selection and more
specific that is Design-Build -Transfer. With the current trend that
helps the client and the main contractor for dealing with the problem
of time and the quality of project is also improved.
2. Procurement Issues
2.1 Issues originating from government, professional, trade and
statutory
Latham Report-Constructing the Team:Provide a review of
construction industry. It was jointly commissioned by the
government and industry.
Common set of standard conditions of contract
Employers’ needs must be met industry
Related content: value for money(recommendation of
construction cost should be reduced by 30% but not on
quality)
DO PHI HUNG 12 CM

9ASSIGNMENT
Banwell reports of 1960s: to recognize the scope under certain
circumstances for the awarding of contracts without the use of
competitive tendering.
Pressure groups formed to encourage change for their members.
For example, Brish Property Federation
Large employers of industry who have bee able to develop
their own contractual procedures. For example, Department of
transport.
Apparent failure of construction industry to satisfy
perceived needs of tis customers.
Attitudes among the professions
2.2 Recommendation from the sector and government sponsored report.
Modernizing construction (1998); aimed to improve the performance
of construction industry. The report id written in three parts:
the challenge in improving construction industry, improving client
and supplier performance, procuring and managing construction.
Other Reports: The Placing and Management of Building contracts
(1994). Acode of procedure for industry (1893), Think about
building (1985), trust and Money (1993), Constructing the Team
(1994).
2.3 Developments and trends in practice
Trends toward greater efficiency
Employers’ desire for single responsibility
Rabid changes in information technology, both in respect of office
practice and manufacturing process.
Influence educational development and research.
DO PHI HUNG 12 CM
10
10ASSIGNMENT
2.4 Aspect of practice
Client’s main requirements: performance, cost, time.
Major considerations: consultants versus constructors, competition
versus negotiation, measurement versus reimbursement, traditional
versus alternatives.
Current Considerations: fair construction contracts, trust funds,
compulsory competitive tendering, reverse auction tendering,
appointment of specialist firms, quality assurances, latent
defects liability and build assurance, added value, private
finance initiative (PFI), competitive advantage, business process
re-engineering.
Risk analysis and management: identification, analysis,
management, willingness of party to accept risk.
2.5 The Egan reports
‘Rethinking Construction’ was published in July 1998 (Construction
Task Force 1998) and represents the work of a special task force
which was set up by the government to identify the scope for
improving quality and efficiency in construction
The Egan Report undoubtedly recognizes both the good and bad in
construction and seeks to build on those aspects of the industry
which are excellent in a worldwide context. However, on balance,
the conclusion of the report is that the industry as a whole is
underachieving and that there should be radical change in key areas
of its performance. These include quality, productivity, cost and
time certainty, and health and safety.
DO PHI HUNG 12 CM
11
11ASSIGNMENT
The Egan Report identified five key drivers of change needed to set
the agenda for the industry:
(1) Committed leadership
(2) A focus on the customer
(3) Integrated processes and teams
(4) A quality-driven agenda
(5) Commitment to people
Accelerating Change: The report identifies three main drivers to
accelerate change in
construction and introduce a culture of continuous improvement in
the industry:
• The need for client leadership
• The need for integrated teams and supply chains
• The need to address ‘people issues’, especially health and safety
2.6 Procurement issues of this project
Time: the project has to be completed in short time to the local
people can active.
Quality: the client’s required standards of design and workmanship
as expressed in the specification
Cost: the cost of constructing project is not over pass the
estimated budged.
Specifications: the contractor comply with the construction
standards in contract.
Environment: the project reduce the influence to environment such
as water pollution and comply with the standards
DO PHI HUNG 12 CM
12
12ASSIGNMENT
Especially works: demand any the especially works such cold store,
the capacity meets the production of fish catching.
Management issues: the conflicts or disputes alway occur between
the main contractor and sub-contractor or primary contractor and
client.
Safety issues or people issues: the workers and and everyone in
construction site have to be ensured health and safety.
Drawing issues: the drawing of project can exist some errors such
as dimension and construct-ability.
Payment issues: the payment of client to the contractor is late
so the project always is delayed.

3. Identifying and discussing the international projectProcurement
Procurement method is “the organizational structure adopted by the
client for management of design and construction of a building or
infrastructure project” (Masterman, 1992). There are three main
procurement methods in construction which include Design-Bid-Built
(Traditional Procurement), Design and Built, and Management
Procurement. However, these procurement methods can not apply any
construction project that we have to base on the requirements of
project such as time, cost, quality, and risks. One thing we can not
forget this is the different requirements between the private or
public project.
3.1 Design-Bid-Build (Traditional Method)
Despite procurement trends and fashions, traditional procurement
routes remain popular and, in many cases, the client’s lead
consultant will be an architect/designer. The popularity of
traditional procurement is shown in Figure 7, which indicates a
current market share of 37% based on turnover.
Figure 7:
The used

traditional
procurement
DO PHI HUNG 12 CM

14ASSIGNMENT
Source: WILEY- BLACKWELL (2007)
In the traditional approach, the employer accepts that design work
will generally separate from construction, consultants are appointed
for design and cost control, and the contractor is responsible for
carrying out the works. This responsibility extends to all
workmanship and materials, and includes all work by subcontractors
and suppliers. The contractor is usually appointed by competitive
tendering on complete information, but may if necessary be appointed
earlier by negotiation on the basis of partial or notional
information. The design and construction can run in parallel to a
limited extent. Whilst this allows an early start on site, it also
entails less certainty about cost. There are three types of contract
under the traditional procurement method (Tuner, 1990)
Disadvantages
The pressures may be borne on
the consultant and
construction teams due to
competing (e.g., economy
versus acceptable quality)
The design and construction
phase is separated so the
tendering phase takes up long
time. This cause can affect
to the project through other
factors such as market
opportunities, market risks.
Advantages
Uses competition bidding in the
selection of the consultant and
contractor to improve the
efficiency and quality for
owner.
The tender price is firmly
because the drawing is completed
before the construction phase.
So the cost of project is
calculated firmly based on
details of drawing. The client
budgets known early stage.
DO PHI HUNG 12 CM
15
15ASSIGNMENT
Contractors have no design
input so the contractor can
met difficult in
understanding the
requirements of client.
Design could affect to the
build-ability of the project.
Sometime designer give
drawing with some works that
contractor can not build. For
example, the length of an
arch roof is 5-8m but in
drawing it is 20m. With this
length the contractor can not
perform the arch roof, if
perform it will require the
modern equipment and
construction method, like
this the cost of work will be
undertaken by contractor.
Designers have limited
ability to price build so
could lead to a more
expensive end product
(Turner, 1990)
Drawing is prepared fully before
the tendering phase. So we can
be easy to change the incorrect
or missed items.
The client has control over
design. There is no
responsibility on the contractor
(Turner, 1990)

3.2 Design and Build
With design and construct procurement method, a contractor is
responsible for undertaking both the design and construction work on
the projects, and should be expressed in the contract. The extent of
design liability should always set out clearly as possible. The use
of external consultants by contractor must be established before a
tender is accepted. To choose the most suitable contractor,
contractors are required to develop a design (from an initial concept
prepared by the consultant appointed to advice the client) to a
certain level, prepare a tender figure, and submit the whole package
which is termed a proposal to be evaluated to meet the satisfaction
of the client. A team of consultants will be needed to assess each
contractor’s proposal.
The first motivation of Design and Built is the eliminating the
inherent conflicts existing between Architect and contractor. Other
reasons are to greater insurance on completion on time (Tuner, 1990)

requirement are accurately
specified.
The design and

construction can reduce
the conflicts. The time of
construction is shorter
and project management
efficiency to be improved.
The client only contracts
with one single
organization so the time
and cost of contract are
reduced.
Drawing is less errors and
variations because the
design and construction
can construct parallel
together. If has mistake
it will be resolved
quickly.
The client has difficult
in evaluating the proposal
and tender submission of
contractor has not
experience or lack of
experience in project.

18ASSIGNMENT
3.3 Management Procurement
Several variants of management procurement forms exist, which
include; management contracting, construction management and design
and manage. In this case of procurement of management, the client has
direct contractual relationships with Project Management, Consultant,
and Contractor. Project Management is paid a fee to professionally
manage, develop a programme and coordinate the design and
construction activities, and to convenient collaboration to improve
the project’s construct-ability. However, the power is not to exceed
the authority of client. Project Management is considered as a
managed tool of client.In the case of management contracting, the
contractor has direct contractual links with all the works
contractors and is responsible for all construction work. In
construction management, a contractor is paid a fee to professionally
manage, develop a programme and coordinate the design and
construction activities, and to facilitate collaboration to improve
the project’s construct-ability (Turner, 1990).
Table 3: The advantages and disadvantages of Management Procurement
DO PHI HUNG 12 CM
19
19ASSIGNMENT
Advantages The client deals with only one firm,
which enables improved coordination
and collaboration between designers
and constructors;
Potential for time savings for the
overall project as design and
construction activities are
overlapped
Under a design and manage form, the
contractor assumes risk and
responsibility for the integration of
the design with construction
Works packages can be let competitively
at prices that are current;
Improved construct-ability through
constructor input into the design;
Roles, risks and responsibilities for
all parties are clear
Flexibility for changes in design.
Disadvantages
Informed and proactive
client is required.
Poor price certainty
Close time and information
control required
Client must provide a good
quality brief to the
design team as the design
will not be completed
until resources have been
committed to the project
(Construction management
and management
contracting)
Client loses direct control
of design quality which
is influenced by the
constructors (design and
manage).Source: (Turner, 1990).
3.4 The most suitable procurement method for fishing port
The project is invested by the government so the Design and Build
can not used for this project. If client use this method it will
occur delicate problems in contractual arrangement. So the client
DO PHI HUNG 12 CM
20
20ASSIGNMENT
should select the Design-Bid-Build method, which creates the
transparency in contractual arrangement and the quality of project is
improved better.
3.5 Conclusion
In summary, the traditional procurement method is the most suitable
method for this project.
3.6 Recommendation
In the future, we should need to improve some things in the
procurement methods such as for the traditional procurement. In these
project that demand the short time and high quality. The client
contract directly with contractor and consultant in the same time and
and by competitive tendering. The performance of design and
construction can be parallel together. The client can control over
the project.
4. Analyze the sequence of ‘design and construction’ in Design and
Built
The development of design and build procurement is well documented
(Janssens 1991, Masterman 2002, Morledge et al. 2006, etc.) and has
grown in popularity since the early 1970s to a market share of some
43% (see Figure 7)
In Design and Build procurement method, the client contracts with a
main contractor, who undertakes for both design and construction work
DO PHI HUNG 12 CM
21
21ASSIGNMENT
of project. The main contractor can get subcontracts with the
subcontractors such as consultant and design subcontractors,
suppliers…etc. These subcontractors are controlled directly by the
main contractor.
The major difference is that instead of approaching the designer
for a building, the employer briefs the contractor direct. The
employer may choose retain the services of an architect or quality
surveyor to assess the contractor’s design or monitor the work on
site. The careful employer always wants some form of independent
advice. The client does not order changes during the construction of
the work. If the client wants to get the changes in during
construction period, the contractor requires items such as costs,
time needed.
The design is undertaken by a contractor so this method can save
the construction time and cost, and harmony between the design and
the contractor’s construction capacities. The final building should
result in lower production costs on site and overall shorter design
and construction period, both of which should provide price saving to
the client. A further advantage to the employer is in the implied
warranty of suitability, because the contractor has provided the
design as a part of the all-in service.
Design and Build is a relatively low risk procurement option for the
client, in terms of cost and time. There can be a risk related to
design and quality, particularly if the employer's requirements were
DO PHI HUNG 12 CM
22
22ASSIGNMENT
not properly gathered and if insufficient time went into examining
the contractor's proposal.
(Jctltd; Tunner, 1990; Mortledge, Smith, Kashiwagi, 2006)
5. Describe the roles and responsibilities of parties in
procurement process in the project
The traditional procurement method is chosen for this project so we
will describe the roles and responsibilities of parties in
procurement phase.
Traditional Procurement
The client
Contracts with the consultant and contractor.
Controlling over design, specified quality, requirements and
standards... etc through his appointed consultants
The client reasonable certainty on construction costs, because a
contract figure is usually known at the outset, although this may
need to be adjusted later, as provided for in the contract.
Draw up the penalties in contract.
Consultant
Responsibilities for design, estimating, tender document and
choosing the contractor.
The consultant have to finish drawings before the tendering phase.
Comply with the standards of drawing in contract.
DO PHI HUNG 12 CM
23
23ASSIGNMENT
Review and recommended acceptance of contractor as the drawing and
specifications
Make periodic visits to the site to assure design compliance and
provide certification efforts as required by the permitting
agency.
Contractor
No design responsibilities on the contractor.
The contractor fills the information into tender document and
appointed by competitive tendering.
The contractor has to draw up the completion day within the
requirement of client.
Comply with the construction standards,
Design and Build
The client
The client appoints the contractor
The client’s requirements can range from a simple accommodation
schedule to a fully worked out scheme design, but generally should
be matched by the contractor’s proposals.
The client has control over the design element included as part of
his requirements.has no direct control over the development of the
contractor’s detail design
Decisions or instructions may be required of the client from time
to time, and the client may decide to appoint an agent either to
advise or to act on his behalf.
DO PHI HUNG 12 CM
24
24ASSIGNMENT
In terms of cost and time this is a relatively low risk
procurement option for the client, but there can be uncertainty
over design and quality, particularly if insufficient attention
was paid initially to the preparation of the client’s requirements
and the checking of the contractor’s proposals
The client may take a standard design from a manufacturer,
sometimes called a ‘package deal’, or enter into a turnkey
contract. The client may decide to place the design decision
making with the contractor.

The client retains overall design control through the professional
team.
DO PHI HUNG 12 CM
25

The costs can be monitored by the client’s quantity surveyor and
action taken as necessary
The client will need to appoint a contract administrator as part
of the professional team.
The client appoints a design team and enters into an agreement
with the construction manager or appoints an in-house manager. The
construction manager does not directly undertake any of the
construction work,
Consultant
Overall design is the responsibility of the client’s consultants
With management contracts, administrative matters relating to
valuations and payments are in the hands of the client’s
consultants
Contractor
The contractor is responsible both for defining packages of work
and then for managing the carrying out of this work through
separate trades or works contracts.
With ‘design and manage’ procurement, the management contractor
not only assumes responsibility for managing the works packages,
but is also responsible for the design team.

7. Analyze contractual arrangement used with subcontractor
Subcontractor is a person who is contracted with a contractor to
provide some works of project which the contractor has agreed to
perform.
7.1 Nominated Subcontract
A subcontractor chosen by the architect or engineer to carry out
specialist work. Appointed on the expenditure of a provisional sum or
prime cost sum included in the contract bills. The nominated
subcontractor enters into a contract with the main contractor but
DO PHI HUNG 12 CM
29
29ASSIGNMENT
there may be a collateral warranty between the nominated
subcontractor and the client.
7.1.1 Intentions of Parties
The Subcontract
The subcontractor should write to the contractor specifying the
discrepancy to the engineer. The subcontractor may be required to
enter into the subcontract. The subcontractor’s liability will not be
expected to exceed the term of subcontract.
Execution of the subcontract works
Subcontractor’s obligations are carry out and complete any works in
compliance with the subcontract document. The subcontractor indemnify
the contractor with reasons such as omission of work, non-
performance...etc.
Strikes
The subcontract works may be effected by a local combination of
workers, strike in any capacity with the project. The contractor
will ensure that the site is kept open for a subcontractor and
subcontractor take all reasonable steps to continue work.

7.2.1 Contractual Arrangement
Article1: The subcontractor’s obligations are similar with the
provisions in the amin contract and the overall aims and
objectives of the employer. The subcontractor will, however, only
be bound by those contract conditions that are written into the
subcontract agreement.
Article 2: The subcontract price is to be exclusive of VAT, in
line with the main contract conditions. If the work is to be
remeasured, the subcontractor’s tender sum will be inserted into
conditions.
Article 3: Settle of disputes, and requirement that all matters
will be first referred to adjudication, then arbitration and
finally to the courts if the dispute cannot be settled.
These follow a similar pattern and content to the nominated
subcontract conditions. However, the domestic subcontractor is not
recognised in the same way by the employer as nominated
subcontractor.
Advantages: There are direct payment provisions by by employer
should the main contractor default in paying a domestic
subcontractor. Neither is there any provision for a early release
of retention.
If the subcontractor does not accept any unfair treatment from the
amin contractor, the engineer can help to settle the disputes.

The domestic subcontractor must comply with all instructions, make
good any defective work and allow access for the architect to
workshops if this is required.
Failure to complete works: The contractor must inform the engineer
of this event. A certificate will be sent and forwarded to
subcontractor concerned.
Practical completion: A certificate should be sent to the
contractor and a duplicate copy to subcontractor .
Defects after final payment: Employer (or the contractor) will
take the necessary steps to recover the amounts for remedial work.
Renomination of a nominated subcontractor is necessary in specific
cases stated in the contract
7.3 The proposed subcontractor for fishing port.
In this project, the client undertakes directly both design and
construction work. So the named subcontract and domestic
subcontractor are not employed because they are only contracted by
the main contractor. For this project, the client should employ the
nominated the subcontractor by the subcontract. Because the
provisions of the nominated subcontract has firmly binding for client
and nominated subcontractor. In summarize, the nominated
subcontractor is the most suitable subcontractor for this project.
8. Evaluate the types of contractual arrangement used with
supplier.
DO PHI HUNG 12 CM
41
41ASSIGNMENT
8.1 Contractual Arrangement
Materials:
Raw materials (cement, brick, timber, etc.)
Often represent the largest expense on the construction site.
Trend: manufactured off-site for on-site assembly, will help to
diminish value of this section.
Components:
Delivered to site in almost “kit” form.
Trend: industrialization (off-site manufactured delivered to site
to assembled easily on-site.
Disadvantage: cost of off-site manufacture may be more expensive.
Goods:
Standard nature, is purchased directly from a catalogue (sanitary
ware, electrical fittings, etc.)
Suppliers are chosen based on quality and performance.
In other circumstances, specialist local suppliers will be used
Disadvantages: the quality of goods is not truly for real.
Bulk purchase: arrange a large order or agreement with suppliers.
Helps to reduce costs of materials, components and goods
Subcontractor (nominated one) may be those who “supply and fix
material” or “supply materials only and be fixed on site by
contractor” .
DO PHI HUNG 12 CM
42
42ASSIGNMENT
Specification in contract document: may identify particular
suppliers to provide materials, components and goods.
Consider a list of alternative suppliers or using the term “other
equal and approved” .
8.2 The contractual arrangement applied for this project
In the construction process, the fishing port requires the big and
long beams. The constructing them is difficult on site and more
risks. So the type of contractual arrangement that client applies for
this project is component. With this contractual arrangement the
contractor or client can reduce the risks in construction process and
achieved a high quality. Although the cost of components are
expensive, but we should compare the cost of installing on site which
can be higher than the cost of fabricated components if installing
occurs risk, accidents.
8.3 The self-evaluation for limitations
In the contractual arrangement of supplier, I have not drawn up the
specifications of payment and settlement of disputes. Such as the
main contractor must pay the required amount within 30 days of the
end of the month during which delivery is made, if any disputes
arises between the supplier and the contractor they must first agree
to take their different to arbitration. We should add the payment and
settlement of disputes in contractual arrangement.
