Procurement and Tendering Flashcards
What is procurement?
The overall process of obtaining construction goods and services
What are the main factors that would determine procurement route selection?
- Client objectives and key drivers, risk allocation
- Must consider and balance the client’s priorities, as you usually find that one procurement route won’t satisfy everything the client wants.
- Cost, time, control, quality, risk
What procurement options are you familiar with? / What are the 4 main types of procurement route?
Traditional
D&B
Management contracting
Construction management
Which procurement route poses the least risk to the employer?
D&B - the design risk is transferred to the contractor (single point responsibility)
Which procurement route is the riskiest for the employer?
Construction management - the employer places individual contracts direct with each trade contractor, construction manager has no risk (except professional negligence)
How to identify client requirements before recommending procurement route?
Through detailed discussions with the client and design team to identify their priorities in terms of cost, time, quality, risk, control requirements and experience.
Client wants to start on site ASAP - what route to recommend?
- My recommendation would need to take into account their other requirements such as cost and quality.
- If time was their overriding priority, then Construction Management or Management Contracting may offer the best solution as they can offer the fastest start on site with overlap of the design and construction.
- This is because start on site is not dependent upon a long tender period however the key tradeoff is a reduction in cost certainty.
Client wants to start on site ASAP but also cost certainty - what route to recommend?
- Design and build procurement may offer the best solution.
- This is because it allows the design and construction to be overlapped rather than being sequential.
- Design and Construction risk is transferred to the Main Contractor with their tender being based on a lump sum price to offer high levels of cost certainty.
What is traditional procurement?
- The design is completed by the client’s design team before competitive tenders are invited and a main contractor is employed to build what the designers have specified.
- The contractor takes responsibility and financial risk for the construction of the works to the design produced by the client’s design team for the contract sum within the contract period.
- The client takes the responsibility and risk for the design and design team performance.
Key advantages of traditional procurement?
- Retaining control over the design can lead to higher quality.
- It offers increased levels of cost certainty before commencement
- Design changes are reasonably easy to arrange and value
Key disadvantages of traditional procurement?
- The overall project duration may be longer than others due to lack of overlap between design and construction.
- There is no input into design and planning by the contractor.
- A strategy based on price competition can lead to adversarial relations.
- There is a dual point of responsibility with the design team controlling the design and the contractor retaining responsibility for the construction
Where might the traditional route be appropriate?
- If the employer has had the design prepared.
- If the design is substantially completed at time of contractor selection.
- The client wishes to retain control over the design and specification.
- If cost certainty at start on site is important.
- The shortest overall programme is not the client’s main priority
What is design and build?
- Where the contractor is responsible for the design, planning, organisation, control and construction of the works to the employer’s requirements.
- The employer gives the tenderers the ‘Employer’s Requirements’ and the contractors responds with the ‘Contractor’s Proposals’, which include the price for the works
What is novation?
- Used in D&B to transfer benefits and obligations of contractual agreement from client to the contractor- terms and conditions the same except parties in agreement.
- Benefits and obligations transferred (i.e. responsibility of payment)
Advantages and disadvantages of novation?
- Advantages - continuity, accountability, assurance on quality for client, reduces risk of post contract changes / disputes, less likely to price in design risk, contractor doesn’t commit as much time/resource to reviewing / validating design
- Disadvantages - Contractor unlikely to be familiar with architect- risk of non-beneficial working relationship, architect underperformance = contractor responsibility, inc prior to their involvement - could be unfair
Alternatives to novation?
Option to assign design team, contractually retained by client (not as good for risk averse)
What are employer’s requirements (ERs)?
- They set out the client’s requirements including the function, size, accommodation and qualityrequirements of the project.
- Their level of detail depends on how much design development has been carried out prior to tender.
- They normally includes the current state of planning permission.
- It should also detail the level of design, structure and specification information to be provided by the tenderers.
What are the Contractor’s proposals?
- The contractor’s response to the Employers Requirements.
- They are the key documentation for the client to consider at the tender review.
- They often include plans, elevations, sections and typical details.
- Layout drawings and specification for materials and workmanship are also provided.
Under D&B, how much design input will the contractor have?
- This depends on the amount of design work the employer has already had completed at time of tender.
- This can range from full design to production information and coordination only.
How does D&B establish cost certainty?
- Lump sum submitted for whole of works provides cost certainty in single stage tender
- Design development responsibility is contractor’s so risk transfer with it
Key advantages of D&B procurement?
- There is a single point of responsibility for the design and construction.
- There is earlier commencement on site.
- Early price certainty is increased.
- The client can benefit from the contractor’s experience harnessed during the design.
Key disadvantages of D&B procurement?
- Clients may find it hard to prepare a sufficiently comprehensive brief.
- The Client has to commit to a concept design early.
- Variations from the original brief are difficult to arrange and are often expensive.
- It is harder to compare tenders and harder to determine whether value for money is being achieved.
Where might the D&B route be appropriate?
- Where there is a need to make an early start on site as there can be overlap between design and construction.
- Where the client wishes to minimise their risk as they transfer design responsibility to the Main Contractor.
- For technically complex projects requiring the contractor’s expertise.
- Where the employer does not want to retain control over design development.
Other consideration for D&B route?
- Additional insurances - Professional Indemnity Insurance (PII) might be needed as the contractor has design responsibility
- Employer usually pays a premium as contractor is taking on the design risk, so usually there is an allowance (sum of money) in exchange
