T4. PROCUREMENT & TENDERING Flashcards
(47 cards)
What are the four main procurement methods?
- Traditional
- D&B
- Construction Management
- Management Contracting
What are the key characteristics of Traditional procurement?
- The client appoints a design team to develop the design.
- The design is completed to a developed stage and then tendered to contractors.
- The contractor is appointed to construct the works based on the completed design.
- The client remains liable for any design errors, as the design is developed and approved by the client’s appointed design team.
What are the key characteristics of D&B procurement?
- The contractor is responsible for both the design and construction of the project.
- The client (Employer) issues an Employer’s Requirements (ERs), which outline the project’s scope and performance criteria.
- The contractor submits a proposal (CPs) in response to the ERs, detailing how they will meet the requirements.
What are the key characteristics of Construction Management procurement?
- The client appoints a CM to manage the project.
- The client has direct contractual relationships with the works contractors.
- The CM is paid a fee for managing the project on behalf of the client.
- Facilitates ECI and overall programme is reduced, as construction can begin before the design is fully complete.
What are the key characteristics of Management Contracting procurement?
- The client appoints a MC who engages works contractors to complete the project.
- The MC has direct contractual relationships with the works contractors.
- The MC is paid a fee to manage the project on behalf of the client.
What are the advantages of Traditional procurement?
- Client retains control of the design.
- Clear separation between design and construction.
- Cost certainty.
What are the advantages of D&B procurement?
- Single point of responsibility (simplifies management).
- Faster programme, as construction starts before design is complete.
- Cost certainty at the outset.
- Early Contractor Involvement (ECI) enhances buildability.
What are the advantages of Construction Management procurement?
- CM manages the works, ensuring coordination.
- Faster programme, as construction starts before design is complete.
- Early Contractor Involvement (ECI) enhances buildability.
What are the advantages of Management Contracting procurement?
- MC manages the works, ensuring coordination.
- Faster programme, as construction starts before design is complete.
- Early Contractor Involvement (ECI) enhances buildability.
What are the disadvantages of Traditional procurement?
- Extended programme (design must be complete before construction).
- Client bears risk for design errors.
- Does not facilitate Early Contractor Involvement (ECI).
What are the disadvantages of D&B procurement?
- Client loses control over design.
- Client pays a cost premium as the contractor assumes more risk.
- Employer’s Requirements (ERs) must be robust to ensure quality.
What are the disadvantages of Construction Management procurement?
- Cost certainty is not achieved until final trade packages are let.
- Increased client risk due to multiple contractual relationships with works contractors.
- No incentive for CM to deliver works at a competitive price.
- Requires an experienced client.
What are the disadvantages of Management Contracting procurement?
- Cost certainty is not achieved until final trade packages are let.
- No incentive for MC to deliver works at a competitive price.
- Requires an experienced client.
How do different procurement routes apportion risk?
- Traditional: Client assumes design risk and any cost overruns due to errors or changes in the design. Contractors carry risk for construction-related issues.
- D&B: Contractor assumes design and construction risk.
- CM: Client assumes cost risk, as they have direct contracts with the works contractors. CM manages process but does not take on direct risk for cost overruns or delays.
- MC: Client assumes most of the risk, similar to CM, but the Management Contractor (MC) is responsible for managing the contractors. There’s no fixed price until all trade packages are let.
What is two-stage tendering?
- A process where the client appoints a contractor early (based on preliminaries and overheads). The contractor acts as a consultant under a Pre-Construction Services Agreement (PCSA) to develop the design and submits a second negotiated tender once the design is finalised.
What is single-stage tendering?
- A tendering process where contractors submit bids based on a complete set of tender documents, with the contract awarded to the lowest or most suitable bid.
What is tendering?
- The formal process whereby potential suppliers submit bids for contracts to provide goods or services
What is negotiated tendering?
- The employer engages directly with a single contractor to negotiate a tender sum for the works.
What are the advantages of single-stage tendering?
- Fixed-cost lump sum for defined works.
- Competitive bidding encourages value for money.
What are the advantages of two-stage tendering?
- Initial competition with price transparency.
- Early Contractor Involvement (ECI) improves design and buildability.
- Work can start earlier.
What are the advantages of negotiated tendering?
- Employer selects the preferred contractor.
- Collaborative approach enhances buildability.
What are the disadvantages of single-stage tendering?
- May not get the preferred contractor.
- Potential for claims due to cost underestimation.
What are the disadvantages of two-stage tendering?
- Lack of competition in the second stage.
- Risk of being locked into a contractor.
What are the disadvantages of negotiated tendering?
- Non-competitive, leading to higher costs.
- Perception of favouritism.
- Exclusion of qualified tenders.
