1. Executive Summary
This report has been prepared to advise the client, Jim, of the different methods of procurement
available, and to advise the method we believe to most beneficial. It is based on the questions
received during the initial meeting and takes into consideration concerns raised.
Each of the procurement methods will describe the advantages and disadvantages for consideration.
2. Methods of Procurement
Traditional (Design, Bid, Build) method
Main points:
- The client chooses and engages with an architect/design team to produce plans and
specifications, working within the client’s budget
- Once the plans are finalized and completed, they are made available to general contractors
where they can bid for the work.
- The bids are compared, and the client selects one. The client will establish a contract with
the successful contractor to build the project.
Advantages:
- The client has full control over every aspect of the project.
- The client directly employs the design team, meaning they will work with the client’s best
interests in mind.
- The process of ‘bidding’ for the work, creates competition and accountability. This can help
to lower prices.
- As the project has been bid for, the costings have been established at the beginning of the
building process.
- As this is often the most used method, it has been tested and well known throughout the
industry.
Disadvantages:
- The client does not get to liaise with the contractor during the design phase, missing out on
any expertise they have to offer.
- As the client has full control, it is very time intensive.

-
If for any reason the project has time or cost overruns, they are the client’s responsibility.
Full documentation is required before moving to the bidding stage of the project.
As the bidding is very focused on ‘being the cheapest’, the client may engage subcontractors
that produce poor quality work or try to find every cost variation they can.
Design and Build (Turnkey) method
Main points:
- Client engages a single contractor.
- Contractor takes responsibility for both the design and construction phases for an agreed
lump sum.
- Client has little input, they simply receive the key to a finished project at the end.
Advantages:
- The cost of the project is fixed at the beginning. They have no responsibilities for cost and
time overruns.
- As there is little involvement other than choosing the plan, the time commitment is minimal.
- As there is a single contractor, they can make decisions quickly, resulting in a quicker
completion time.
Disadvantages:
- The single biggest disadvantage of this method is the minimal input from the client’s
perspective. This means the client has little control over design of the building.
Management Approach
Main points:
- The client engages a construction manager at a fixed fee to organize tenders.
- The risk and responsibility are delegated to the construction manager.
- Client is still responsible for changes and overruns which are unexpected even after the
maximum price has been agreed.
Advantages:
- This approach is remarkably similar to the traditional method, but often will be quicker due
to the construction manager organizing the design and construction teams. So, construction
is able to start before the design process is completed.
- The overall project can benefit from the construction managers expertise being involved in
the design process. The experience will also help in choosing the best contractors.
Disadvantages:
- Although engaged by the client, the construction manager is not the client representative.
Because of this, they are not always working for the best interests of the client.
- The price of the project is not established in the beginning, not until all subcontractors have
been selected.
Integrated Project Delivery Approach
Main points:
- The 3 main parties work together, they include; client, architects and engineers,
construction contractor. They work together on all phases of the project.
Morgan Payne #5026273
-
As it is a collaborative process, shared risk and reward contracts are made to encourage
everyone to work together.
Advantages:
- This approach can result in a more efficient project, meaning a higher quality of work
achieved within the budget.
- The efficiency can lead to a shorter delivery time.
- The project can be integrated with Business Information Modelling which aids in delivering
higher results.
Disadvantages:
- The contracts are more complex and requires higher levels of trust.
- If all parties are not able to share information easily, such as a single digital platform, it can
create issues with different documents and access.
3. Recommendation
The project is quite different to a standard design and build project, it is large in scale and there are
still many details that will need to be decided. The client has indicated that there is not a timeframe
in mind and budget has potential to be negotiated.
I would recommend the integrated project delivery approach. The approach will give the client
sufficient input while still being able to engage directly with experts at every stage of the project. It is
also clear the client has high expectations of the outcomes they would like to receive and have a
budget in mind to achieve this. This approach offers the best potential to meet the key aspects of
the clients brief.
Fantail’s Flight Village – Stages of Building Project
Within any construction project, they can be divided into 3 key stages; Design, Bid (tender),
construction. We will explain the 3 stages in more detail below.
Stage 1 - Design
As the name suggests, this is the stage of the process where designing and planning take place.
Depending on the project it may just be a small team of designers/architects. While larger or more
complex projects may require engineers, quantity surveyors, town planners, landscape designers
and more.
The process starts with a meeting with the client. This is one of the most important meetings, as it is
used to identify the client needs and wants. It is also includes discussing other aspects that can play
a pivotal role in the design such as, budget, timeframe, and physical space. This is then used to
create a design brief, which is used to create the foundation of the contract between the parties.
The designer will use the design brief to produce a preliminary design or designs. These will all meet
the brief but vary in slightly different ways. It is a way of presenting different ideas. This is also a
time where specialist will be engaged to make sure consideration is given to aspects unique to an
individual project. Other specialist such as a quantity surveyor may be engaged to cost the project
and ensure it meet the contractually agreed budget.
Once all parties have agreed on the preliminary design that meets all requirements of the brief, the
project moves to the developed design stage. The design is developed adding consideration for
Morgan Payne #5026273
spatial flow, making the building functional for people to interact. When the spatial design has been
completed it is most likely this part of the design will not change as it would add high costs to the
price of the project.
Specialist are engaged to input their strategies, the designer will then incorporate these into the
design and the end product would be the final design.
The developed design then needs to be presented to the client in a way in which they can
understand, in order to receive approval and sign off.
The final stage is the development of a detailed design. This further refines the preliminary design
and adds technical information to the project. The technical information provided in the drawings
will be used by the contractors and sub-contractors to provide tenders for the work.
Stage 2 - Bid (Tender)
The bidding is stage 2. First the project is set up for tender and includes deciding on all the
documentation and processes, identifying suitable contractors and that approach which will be used
for the contract. It is then made available to either specific contractors or released to public for
expressions of interest (EOI). Contractors use the information provided in the detailed design to
prepare their tender quotes. They are also given opportunity to ask questions, of which answers are
made public, so all parties have the same information. Once all tenders have been received the
client and designer will short list contractors of which a further interview may take place. Once the
client has completed vetting the contractors, a decision will be made, and the client decides which
contractor to award the contract to.
Stage 3 - Construction
The main contractor will become responsible for the construction stage. Although the client will still
be present, they have less input, as all decisions should have been made at this point.
Step 1 of construction involves a mobilization meeting which take place approximately 2 weeks
before construction on site begins. All parties that are involved are invited including, client, designer,
project manager, main contractor, and quantity surveyor. They review the project as a whole and
establish the working relationships. It is also a chance for any questions to be addressed. By the end
of the meeting it must be clear all parties understand any work outside of the scope must be agreed
on before work is carried out.
Step 2 is the on-site construction phase, simply put this is when the construction work takes place.
Many variables can affect the progress including weather, product supply, etc. It is important regular
meetings take place during this step, so all parties involved are clear of their requirements.
Step 3 is the pre-finish or snagging stage, this happens approximately 2 weeks from the completion
of the contract. Again, the client, design team and contractor perform a site inspection where they
assess any items that have not yet been signed off, not completed to specifications, substandard
workmanship or unfinished work. They provide a list known as the snagging list. The contractor is
then required to remediate all items on the list before any more invoices from the contractor are
processed.
Step 4 is the practical completion stage. A final site inspection is setup where all work is checked.
Once everyone agrees that all work has been completed satisfactorily, then it can be signed off. A
practical completion certificate is issued and released for the project. A period is put in place known
Morgan Payne #5026273
as the defects liability period, where the client retains a fee of approximately 3-5% of the contract
sum.
Step 5 is the building handover stage, where the client, as well as receiving the keys also receives all
documentation including, all manuals for machinery, operation and maintenance manuals, as-built
drawings, producer statements from specialists and the code of compliance. Any insurances held by
the contractor end and the client is able to move in.
Step 6 is the final completion stage. This stage is complete when the period of time that was put in
place for the defects liability is finished. The client and the contractor perform a final site inspection
and the final certificate, along with the retention money is released.
Fantail’s Flight Village – Design and Construction Team
Client
Although it may seem unnecessary to include the client as part of the team, they are the very center
of the process. They also have considerable input at all stages of the project including deciding what
they want, when they want it and how much money is available to achieve it.
Clients Representative
In the case of the client not having enough time or experience, they may choose to appoint a
representative. They will ensure that all aspects of the project are completed to the clients
requirements. It is common that the client may appoint the designer, main contractor, or project
manager to act as the central point for things such as communication.
Designer
The designer will be an architect, architectural designer, or draughtsman, which may be an individual
or a company. Their role is to take the brief of the client and create working drawings. They are the
first person the client will engage with.
Main Contractor
The main contractor is the company engaged to carry out the construction works. They were most
likely the company who were successful in winning the tendering process. They become responsible
for running the construction site, including all health and safety requirements. The main contractor
is a pivotal connection point between client, designers, and subcontractors.
Subcontractors
Subcontractors and specialists in their field and are engaged by the main contractor. Occasionally,
the client may have specific subcontractors they would like to use, but this is not common.
Subcontractors include trades such as, electricians, plumbers, painters, tilers and roofers.
Site Manager
Morgan Payne #5026273
The site manager is the point of contact for day to day operations, as the name suggests they are
always present on site and the go to person for subcontractors that require clarification of work.
Other Specialists
Depending on the scope and complexity of the project, it may be required to engage specialists to
meet the desired outcomes. These specialists include;
Structural engineers – if the design requires engineering solutions and certification.
Civil engineers – when services such as roading is required.
Quantity surveyor – to calculate costings of the project.
Landscape architects – to design the grounds prior to construction of cottages.
