Procurement and Tendering Flashcards
What is procurement?
The overall strategy for identifying a need, and then supplying goods or services to meet it
What is tendering?
Tendering is the specific way in which goods and services are bought
What are the 4 main procurement routes?
- Traditional
- Design and Build
- Construction Management
- Management Contracting
What are the Pros and Cons of Traditional Procurement?
Pros:
- Client maintains control of the design
- Price certainty (lump sum contract)
- Changes are relatively cheaper and quicker to make
Cons:
- More time consuming
- Design risk lies with the client
- Can’t take advantage of Contractor expertise
- An incomplete design will limit cost certainty (prov sums)
What are the Pros and Cons of Design & Build Procurement?
Pros:
- Overlap design and construction process, saving time
- Design risk lies with the Contractor
- Benefit from the contractor’s experience
- Cost certainty (lump sum contract)
Cons:
- If the ER’s aren’t detailed enough, quality could suffer
- Relatively more difficult and costly to make changes
- Clients have to decide on a design early
What are the Pros and Cons of Construction Management
Pros:
- Quicker start on site due to design and build overlap
- Contractor/Sub-Contractors can input on design
- Early involvement from the CM helps with buildaility
Cons:
- No cost certainty until the last package is let
- Risk of scope gaps
- Requires a lot of Client experience
- Lots of admin
What are the Pros and Cons of Management Contracting?
Pros:
- Less admin for the client when it comes to payments etc
- Quicker start on site due to design and build overlap
- Contractor/Sub-Contractors can input on design

Cons:

What is the difference between Construction Management and Management Contracting
The Contractual link is between the client and subcontractors under Construction Management, whereas under Management Contracting the Contractor is the one in contract with the subbies.
When would Management procurement routes be suitable?
- On complex projects with a number of specialists required
- Where there is a need to start on site quickly
- When the client has a lot of construction experience
What is GMP?
Guaranteed Maximum Price
- Typically used on D&B lump sum contracts and means that the price will not change unless there is a design change requested by the client
- The contractor bears the risk of design development, on site discoveries etc
- A mechanism should be put in place to agree what happens if savings are made below this GMP
What are the types of tendering?
- Open
- Selective (Single or Two Stage)
- Negotiated
What are the pros and cons of single stage tendering?
