Project Delivery Methods Flashcards
What are the 3 major classifications that contracts are structured?
- Traditional
- Design-Build
- Construction Management
How can a builder be selected under Traditional contract structure?
- Open bidding
- Prequalified bidding
- Qualifications and negotiation
option 1&2 may be required for public projects (negotiations allow for opportunity for abuse)
option 3 can permit builder to join the project team during the design stage
Linear Model best represents which type of contract structure?
Traditional
What are the three stages of a traditional PDM?
Concept/Design, Procurement, Construction
3 Prime players in traditional PDM
Owner, Designer, Builder
How many contracts are normal for a Traditional PDM?
2.
Owner and Designer - Fee based, Lump sum
Owner and Builder - (Unit Price, Lump Sum, Negotiated)
What are the roles and responsibilities of the players in a traditional PDM?
Owner - Program (when, where, what etc.), Finance (funding for project)
Designer - Design (and field services)
Builder - Delivery of completed project
What are some advantages and disadvantages of traditional PDM?
Advantages: Familiar, procedure and contractual rules are well understood, final cost often known for linear projects, open bidding provides lowest price available,
Disadvantages: Builders input not available until construction stage, no contract between designer and builder, no opportunity to overlap design and construction to reduce time, unforeseen conditions are likely to occur and leads to disagreement
What types of projects are good for Traditional PDM?
Well-defined scope, minimal risk of changes, time is not a significant factor (think overlap) minimal political, technical or schedule restraints
What are some permutations of the design build model?
- Contractor led - builder engages design professionals required for the project
- Integrated - design-build entity provides most services itself
- developer - used by owners who do not intend to take financial responsibility for the project until it is completed
Characteristics of the design-build model.
two continuous stages - design-build
two prime players - owner and design-build entity
one contract - owner and design-build entity (typically fixed price, lump sum)
Roles and Responsibilities of players in design-build model.
owner - program (where, when what..) finance (unless developer is to finance)
design-build entity - design and deliver project, manage approvals with Project Stakeholders (MOTI, municipality)
Advantages and Disadvantages of Design-Build Model
Advantages - single point of contact for owner, good communication (good results lead to more profits), construction input during design stage can reduce costs, project can be FAST-TRACKED (2 continuous stages)
Disadvantages - no direct connection b/w owner and designer, lack of checks and balances (owner may hire his own consultant to oversee), construction quality may erode due to cost saving strategies
What types of Projects are good for Design-Build Model
- projects with tight schedule
- highly technical projects
Extensively used for industrial construction (producing a good –> fast track is important time to operational)
What is the Construction Management Method
- one firm controls all activities
- firm represents owner in all CM activities (start to finish, conception to completion)
- firm controls flow of information
- once contractual relationships are established, CM firm controls prime/main, all subs, as well as major suppliers fabricators
- CM firm uses the project schedule to move things in timely and cost effective manner
