Procurement & Tendering Flashcards
(38 cards)
Tell me the difference between Management Contracting and Construction Management.
Management contracts – where the management contractor undertakes to manage the carrying out of the work through works contractors, who are contractually accountable to him.
Construction Management – where the construction manager undertakes to manage the carrying out of the work through trade contractors but the client is involved in the directing of the project, and the contracts with the trade contractors are directly with him
What would be an appropriate route if time was the driving factor of the client?
Negotiation
What do you consider to be the key documents to be issued during the tender process?
Contract documents
Employers Requirements
Why did you recommend a Minor Works Contract?
I recommended a Minor works Contract as the strip out works were simple in character, there was minimal design for the contractor, the drawings for the strip out were well defined and presented. There was unlikely to be any unforeseen site constraints or discoverables. It was a relatively small strip out of a vacant building.
Why not D&B or Intermediate?
D&B – no design for contractor – more risk – employer experienced.
Intermediate – advance payment not required – no testing or opening up required – does not meet recommended value for using a IC
Why would using a Minor Works contract attract more tenderers
Reduced risk on contractors side
Possession of the site remains with the employer – less cost and complication on contractors side for insurance/security etc
Where is the advice in this statement?
Once I had produced my report and analysed all the tender returns, I informed the client that the prices provided by the steel window contractors were exceptionally high and that I would advise reducing the scope, complexity and quantity of the steel windows/doors to the design team as a VE option to be progressed. This would reduce the overall cost of the steel windows and doors package.
On 4more london - how did you come to a preferred tenderer? How did you go about informing tenderers?
What was the process you took to make sure all tenders were equal?
Sideby side comparison which included normalising the tenders to exclude any abnormalaities or include costs where a contractor had not included for an item.
What would have been the negatives of procuring the enabling works early on 71 hopton?
What was in your ITT for 4more?
What is procurement?
The overall process of acquiring construction work or services.
What should be considered when selecting a procurement route?
- the specifics of the project
- the client objectives regarding:
- Cost
- Time
- Control
- Quality
- Risk
What are the main procurement methods?
- Traditional and General Contracting
- Design and Build
- Management Contracting
- Construction Management
What is traditional procurement?
The design is completed by the clients design team before competitive tenders are invited and a main contractor is employed to build what the designers have specified.
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 team for the contract sum within the contract period
- the client takes responsibility and risk for the design and design team performance.
- the client retains design responsibility and holds the direct contractual relationship with the architect
When might traditional procurement 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 improtant
- The shortest overall program is not the clients main priority
What are the advantages of traditional procurement?
Retaining control over the deisng can lead to higher quality
It offers increased levels of cost certainty before commencement
DEsign changes are reasonably easy to arrange and value
What are the 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
What is design and build?
Where the contractor is responsible for the design, planning, organisation, control and construction of the works to the employers requirements.
How does D&B work?
The employer gives the tenderers the “employers requirements” and the contractor responds with the “contractors proposals”, which include the price for the works.
- The client transfers design responsibility to the main contractor who holds the direct contractual relationship with the architect.
When might D&B be appropriate?
Where there is a need to make an early start on site as there can be overlap between design and build 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 contractors expertise
Where the employer does not want to retain control over design development.
What are the advantages of D&B?
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 contractors experience harnessed during the design
What are the disadvantages of D&B?
- 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.
