- The client objectives regarding cost, time, control, quality and risk
a) Traditional / general contracting
b) Design and build
c) Management contracting
d) Construction management
How does traditional procurement work?
When would you use Traditional Procurement?
a) If the employer has had the design prepared
b) If the design is substantially completed at time of contractor selection
c) The client wishes to retain control over the design and specification
d) Cost certainty at start on site is important
e) The shortest overall programme is not the client’s main priority
What contracts might be used for traditional?
Most JCT and NEC ECC forms are applicable
a) Competitive fairness and transparent process – increase value for money
b) Design led – can ensure quality
c) Price certainty before commencement
d) Well known procedures
e) Changes are reasonably easy to arrange and value
a) Overall project duration may be longer than others – sequential process
b) No input into design and planning by the contractor
c) Strategy based on price competition – could lead to adversarial relations
d) Dual point of responsibility – design team for design and contractor for construction
e) If design not complete at time of tender, cost and time certainty are reduced
How does design and build work?
When would you use design and build?
a) Where there is a need to make an early start on site – can overlap design and construction
b) Where the client wishes to minimise their risk – not got responsibility for design
c) For technically complex projects – benefit of contractor’s expertise
d) Where the employer does not want to retain control over the design development
What contracts can you use for design and build?
NEC ECC, JCT DB 16
a) Single point of responsibility for design and construction
b) Earlier commencement on site
c) Early price certainty
d) Benefit of contractor’s experience harnessed during design
What are the disadvantages of design and build?
a) Client may find it hard to prepare a sufficiently comprehensive brief
b) Client has to commit to a concept design early
c) Variations from the original brief are difficult to arrange and often expensive
d) Harder to compare tenders – harder to determine if getting value for money
e) Ease of fabrication may be prioritised above aesthetic quality
f) May be less real competition due to fewer design and build firms
How much design input will the contractor have in Design and Build?
Who carries out the design for the contractor in design and build?
How does Management Contracting work?
When would you use management contracting?
What contract might be used for management contracting?
NEC ECC and JCT both have management contracts.
What are the advantages of management contracting?
a) Overall project duration is shorter due to overlapping design and construction
b) There is contractor contribution to the design and planning process
c) Changes can be accommodated in packages not yet let if they have no further impact
d) The works are let competitively at current market prices on a firm price basis
