Procurement And Tendering L3 Flashcards
What would you take into consideration when looking at Time?
- How much time is there to prepare a complete design
- When is the site available
- When is the work required to be completed
- What are the phasing or sectional requirements
- The financial effect of a delayed completion
What would you take into consideration when looking at Cost?
- Is a Lump Sum, Target Cost or Re-measurement option required when the contractor is appointed
- The impact of inflation over a lengthy contract period
- The time of fixing the price of the works and certainty of out-turn costs
- What level of risk is acceptable to the client
- What level of risk is acceptable to the contractor
What would you take into consideration when looking at Quality / Performance?
- Is retention of design control and important issue
- Will the nature of the works require stringent supervision
- Is the building listed or in a conservation area
What are the components of a tender report?
- Executive Summary and Recommendation
- Introduction
- Tender Procedure
- Tender Pricing
- Programme
- Qualifications
- Detailing of any errors found
- Remaining risks
- Other information Submitted
- Recommendation to the client
- Next Steps
What is Traditional Procurement?
The design is completed by the clients design team in detail before competitive tenders are invited to submit tenders based on a fully developed design.
Assuming no significant design changes, arise, construction costs can be determined with reasonable certainty before work begins.
The employer retains the design consultants during construction. Consultants, prepare any additional design information and review contractors design portions, prepared by the contractor
How does traditional procurement work?
- The contractor takes responsibility and financial risk for the construction of the works to the design produced by the clients design team for the contract sum within the contract period
- The client takes the responsibility and risk for the design and performance of the design team
- Speculative risks are balanced as between the parties, more in the client’s favour on a lump sum contract but less so with a measurement contract
What are the advantages of Traditional Procurement
Advantages
• High cost certainty at point of contract
• Full ability to control design and specification – can ensure quality
• Competitive fairness and transparent process – increases value for money (Value for money is not about achieving the lowest initial price: it is defined as the optimum combination of whole life costs and quality.)
• All tenders produce a submission, based on the same information brackets, therefore tender returns are much easier to compare).
• Minimal built-in contract to risk premium (unlike design and build).
What is Design and Build Procurement?
- Design and Build is more accurately a type of contract, however, it is commonly referred to as a procurement route and, therefore, needs to be considered here.
- Where the contractor is responsible for the design, planning, organisation, control and construction of the works to the employers requirements
- A single or two stage approach may be adopted. It is more common for the single stage method to be restricted to buildings of a reasonably simple nature where the risks to the contractor can be easily defined.
How does design and build work?
- In its simplest form the employer gives tenders the ‘Employer’s Requirements’ and the contractors respond with the ‘Contractors Proposals’, which includes a price for the works
- A method where the contractor is responsible for undertaking both design and the construction of the work in return for a lump sum price. There are variants on this option depending on the degree to which initial design is included in the client’s requirements.
What are the advantages Design and Build Procurement?
Advantages
• Design and construction risk sits with the contractor (single point of responsibility).
• Inherent buildability input – contractor’s experienced harnessed during design
• High cost certainty at point of contract over Traditional contracts.
• More efficient / earlier commencement on site is possible – design/construction overlap
What is Novation?
• A new contract that transfers the rights and obligations of one contractual party to a new third party i.e. design rights and obligations of the architect transferred to the contractor
What is the difference between novation and assignment?
A novation agreement transfers both the benefits and the obligations of a contract to a third party. In contrast an assignment does not transfer the burden of a contract. This means the outgoing party remains liable for any past liabilities incurred before the assignment.
If the design team is novated, what should the client put in place?
A collateral warranty to the design team. Creates a contractual relationship between parties where there would otherwise not have been any.
What is Management Contracting?
The employer appoints a management contractor to manage the entire building process who in turn appoints trade contractors to carry out the construction works.
The management contractor is usually paid a fee percentage based on construction costs.
The management contractor has a direct contractual link with the trade contractors and is responsible for the overall construction works.
How does Management Contracting work?
- Appointment of the contractor is usually by negotiation or tender, and interview. He is paid a management fee. The work packages are let by competitive tender.
- The management contractor has direct contractual links with all of the works contractors
- The have the responsibility for the construction works without actually carrying them out
- Not all of the design need to be completed before the first works contractors start work
- The client retains overall design control through the professional team
- There is no certainty of over costs at the outset and work proceeds on the basis of the contract cost plan. Final costs will not be known until the last work package is let. However, the costs can be monitored by the clients QS
What are the three main types of tendering?
- Competitive single stage
- Competitive two stage
- Negotiated tender
What are the methods of selecting tenderers?
- Open tendering
- Selective tendering
- Single contractor selection
What are the advantages/disadvantages of negotiated tender on DandB?
Advantages
- Most contractor involvement in design process
- No programme implications of tendering
Disadvantage
- Lack of competitiveness
- May not be suitable for public procurement contracts
What are the advantages/disadvantages of negotiated tender on traditional?
Advantages
- Contractor involvement throughout process will enable more effective mitigation of risk throughout the design process by the contractor
-No tendering period required on programme
Disadvantages
- No competition may result in high contractor offers
- May not be suitable for public procurement contracts
What are the advantages/disadvantages of negotiated tender on MC/CM contracts?
Advantages
- No tendering required in programme
Disadvantages
- No competition at all on Prleims and OHP and programme
What are the advantages/disadvantages of single stage tender on DandB contracts?

What are the advantages/disadvantages of single stage tender on traditional contracts?
Advantages
- Most competitive price
- The most linear form of tendering
