What is project delivery system?
the organization of each participants required to complete/deliver a project
Examples of PDS?
- DBB
- Pure CM
- CM at Risk
- Design Build
- IPD
Tell me about the structure of DBB
Tell me some information about DBB
- Hire a design professional in charge of preparation of design and contract
- Competitive bid or negotiation with contractors
- Contractor is only responsible for execution of work
- Lump sum bids adopted whereby the owner assigns project risk to the contractor
List some Pros and Cons of DBB
Pros
- Well known method
- Cost already defined
- Good contractual protection for the owner
- Owner not too involved
Cons
- Sequential and linear process which prevents task overlapping and the efficiency
- Construction can’t start until design is complete
- Design not reviewed for constructability before construction
Tell me about the structure of PCM
Tell me some information about Pure CM
- Owner hires both a design firm and a construction management before beginning of construction
- CM is a professional service
- Team concept: owner, A/E, Cm
- PCM as facilitator for conflict and get paid a fix fee
What do PCM do?
- Predesign estimate
- Cost and constructibility input to design process
- Award of contract
- Adminstration of contract
Why Construction Management are better for management services then General Contractor or A/E
- GC lack predesign estimating, interaction during design, contract administration
- A/E lacks accurate cost, constructibility info, coordination and control, general conditions construction, and maximum price.
Pros and Cons for PCM
Pros
- One trusted common reference point for construction : CM
- Great flexibility in schedule
- Small financial risk for PCM
Cons
- Participants must all be cooperative and communicated
- All parties must be committed from the gecko
- Small incentive for CM
- High risk of loss of reputation for Cm
Tell me about the structure of CM at risk
What is CM at risk
- Contractual relationships between CM and sub contractors
- Cm does the ones in PCM as well as packaging of construction into separate contracts and coordination and control of multiple contracts
- PCM provides as management service but has 100% of service
- CM hands out 100100% of world to contractor
- Fully Responsible for the execution of project
- They don’t do any work but hire the workers
What are pros and cons of Cm at risk
Pros
- Owner risk Is lowered
- Economy determines who comes out with profit
Cons
- Owner takes responsibility for design defects
- Owner may not have full control on contract changes
Tell me about the Design Build structure
Tell me about design build
- Owner hires design/build firm that completes design and construction
The firm can be a design/build but also be a joint of a construction and design company –> miunimilize conflict as the management and design are from the same company - the firm hires subcontractors
- the work can be done before design –> efficient
What are the pros vs cons for design build
Pros
- Allows fast track –> someone who values time > money
- good interactions among design and construction participants
Easier incorporation of changes in most cases
Good for complex project
Cons
- Pricing isn’t possible at the beginning
- Risk of sacrificing quality to protect profit
- Quality (goes down) - Profit (goes up)
What is the structure of an IPD?
Can you tell me some information about IPD
- key project stakeholders sign on multiparty contract
- profit sharing scheme
- timing engagement is different
- no fault working environment
- integrated leadership
