Procurement and Tendering - L3 Flashcards
What is procurement?
- The overall act of obtaining goods and services for a construction project.
- There are several routes by which the design and construction of a building can be procured. The selected procurement route should follow a strategy which fits the project criteria and objectives.
What are the main factors which typically govern procurement route selection?
- The key is to identify the client’s objectives and key drivers in terms of time, cost and quality. Other factors such as risk allocation should also be considered.
- It’s unusual to satisfy all these elements with on procurement route. Consideration must be given to the clients list of priorities to identify the most appropriate procurement route.
Which procurement options are you familiar with?
- Traditional procurement.
- Design and Build.
- Management Contracting.
- Construction Management.
What is traditional procurement?
The traditional procurement route involves separating design from construction. The employer first appoints consultants to design the project in detail, contractors are then invited to submit tenders based on a fully developed scheme.
What are the key points of traditional procurement?
- The design is completed by the employer’s design team before competitive tenders are invited. The contractor is then appointed to build what the designers have specified.
- The contractors tender is based on a complete design produced by the employer’s consultants (with exception to Contractor’s Design Portions or CDP).
- Assuming no significant design changes arise, construction costs can be determined with reasonable certainty before works begin.
- The emnployer retains the design consultants during construction. The consultants prepare any additional design information and review CDP designs prepared by the contractor.
What are the key advantages of traditional procurement?
- The employer retains control of the design.
- The design is largely finalised before the contractors tender for the build; this means the employer knows exactly what they are getting.
- All tenderers produce a submission based on the same information (tender returns are much easier to compare).
- Assuming the design is robust, reasonable price certainty is achieved at contract award.
- Minimal built-in contractor risk premium (unlike design and build).
What are the key disadvantages of traditional procurement?
- The overall project duration may be longer than a design and build procurement (limited opportunity to overlap design and construction phases).
- Zero or limited contractor buildability input.
- Design risk is retained by the employer, any changes post-contract will be a variation or compensation event.
- Dual point of responsibility (employer for design and contractor for construction).
When might traditional procurement be appropriate?
– The employer may have specific or detailed design requirements.
– Cost certainty is important (traditional has significant advantages over construction management or management contracting procurement routes).
– The shortest overall program is not the employer’s main priority.
What is design and build?
The contractor is responsible for completing the design and executing the construction phase of the project. This is a completely different approach to delivering a project via traditional procurement, where the client appoints consultants to undertake the design and then a contractor is appointed to construct the works.
What are the key points of design and build procurement?
- Under the JCT contract, the employer’s team produce a set of employer’s requirements (ERs), the contractor and then responds to the ERs with their contractor’s proposals (CPs).
- The original employer’s design team may be novated to the contractor for continuity, or the contractor may appoint their own design team.
- The contractor is responsible for the design, planning, organisation, control and construction of the works.
- Design risk is transferred to the contractor.
What are the key advantages to design and build procurement?
- Single point of responsibility for design and construction (Contractor).
- Earlier commencement on site is possible (if design and construction can be overlapped).
- Benefit of contractor’s experience harnessed during design (buildability input).
- Design and construction risk rests with the contractor.
- Provides more cost certainty than traditional procurement.
What are the key disadvantages to design and build procurement?
- The design is only as good as the employer’s requirements (the employer may find it difficult to prepare a sufficiently comprehensive brief).
- More complex to compare tender returns.
- Employer changes can be difficult to value and expensive.
- The employer may have less control over aesthetics and quality.
- The contractor will build in risk premiums into their tender return.
When might design and build procurment be appropriate?
- When there is a need to make an early start on site (D&B has potential to overlap design and construction).
- Where the employer wishes to minimise the risk profile (design risk is passed on to the contractor).
- For technically complex projects, the design will benefit from the contractor’s buildability input.
- Where retaining control of the design is not a priority.
What additional insurance might be required under a D&B contract?
The contractor and the design team will have design responsibility; therefore, it is likely additional professional indemnity insurance (PI Insurance) will be required.
What are the employer’s requirements (ERs)?
The expression employer’s requirements are used to describe the document(s) produced by the employer to set out its requirements in relation to the project (including performance specifications, drawings, initial designs etc.) and this is what the design and construction of the works will be based on.
What are contractors proposals (CPs)?
- CPs are prepared by the contractor which responds to the employer’s requirements.
- In this document(s), the contractor will produce detailed design information (based on the employer’s requirements), which will require further development throughout the course of the project.
Which procurement route poses the least risk to the employer?
Design and build, this is because the design risk is transferred to the contractor.
Why does the employer usually pay a premium for design and build procurement at tender stage?
The contractor will usually factor in an allowance within the tender return in exchange for taking on the design risk.
On the design and build, who executes the design for the contractor?
The contractor may use their own in-house design or they can appoint external consultants. The employer’s original design team can also be novated to the contractor.
What is construction management procurement?
The employer directly appoints multiple subcontractors (referred to as trade contractors) instead of employing a single main contractor. The single feature that makes construction management unique, particularly from management contracting, is that the employer places individual contracts with separate specialist trade contractors themselves.
What are the key points of construction management procurement?
- The employer places a direct contact with each trade contractor and utilises the expertise of a construction manager to coordinate the works.
- The construction manager programs and coordinates the works.
- The construction manager has no contractual link with the trade contractors.
- The construction manager has no vested interest in the financial outcome of the project and, barring professional negligence carries no risk.
What are the key advantages of construction management procurement?
- Speed (early start on site).
- Overall project duration reduced by overlapping design and construction.
- The construction manager can contribute to the design and project planning processes.
- Changes in design can be accommodated without paying a premium.
- Prices may be lower due to direct contracts with trade contractors.
- The employer has means of redress with trade contractors through direct contractual links.
What are the key disadvantages of construction management procurement?
- Price certainty is not achieved until the last trade packages let.
- The procurement route requires an informed, experienced to and proactive employer to work.
- The employer has a lot of consultants and contractors to manage.
When might construction management procurement be appropriate?
- The employer is experienced in construction and has the suitable resources to manage the project.
- The employer wants to achieve an early start on site.
- The employer wants the flexibility to make minor changes to the design / specification throughout the process with minimal impact on time or finances.
- The project is technically complex and requires detailed engagement of specialist consultants and trade contractors.
