Types of Project Delivery
Design-Bid-Build:
What characterizes this form of contract delivery?
- Two separate sequential contracts between the owner and the architect, and the owner and the construction contractor.
- The design project is followed by the construction project.
Design-Bid-Build:
At what stage does construction commence?
After design is substantially complete.
Design-Bid-Build:
Describe the phases of the Design-Bid-Build Method
- Begins with the owner contracting with a designer (architect) to complete a set of drawings and specs (bid documents)
- Owner hires a contractor by competitive bidding to build the facility under a stipulated price construction contract
- architect administers specified aspects of the construction contract, provides general review of construction works, certifies the payment of the contractor’s invoices, and has legislated and contractual involvements at project completion and during the warranty period.
Design-Bid-Build:
What are the advantages of this project delivery method?
- Most commonly used in the industry - well understood
- Owner knows the cost of the project with a high degree of certainty before construction beings (under a stipulated price contract)
- Owner has a thorough understanding of the projects design and program functionality prior to construction
- Owner has a direct relationship with the designer and the constructor
- Competitive pricing
Design-Bid Build:
What are the disadvantages of this project delivery method?
- Separation between the designer and the constructor limits information exchange about construction costs and constructability
- Clients may expect that the project can be completed for the tendered price without inclusion of a construction contingency
- Contracts, particularly for public sector projects, are awarded to the low bidder who may not be well qualified to do the work
- Generally longer overall time to deliver the project
Construction Management:
Describe this method of project delivery
A project delivery scenario were the
design team is augmented with the addition of a construction manager (CM) at an early stage to advise on and oversee such elements as schedule, cost, construction method or building technology.
Construction Management:
A CM typically has career experience as an:
- Architect
- Engineer
- Contractor
- Developer
- Individual specifically trained as a CM
Construction Management:
When is this method of project delivery most commonly used?
- Large and complex projects
- Were time is limited and construction may begin before design documents are complete
- When changes in design are anticipated and rapid responses are required
- When the general contractor does not want to assume the risks of a stipulated price contract
Construction Management:
At what capacity does the CM typically serve the project.
Depends of the contract. They can add value to the project by advising all or any particular stage of design, documentation, or construction, or any combination of the above.
Construction Management:
What are the typical responsibilities of a construction manager?
- Assists the preliminary planning of the design requirements of the project
- Advises on schedules, budgets and costs of construction methods, material selection, and detailing during design
- Advises on and arranges for services, trade contractors, and suppliers to carry out the work
- Planning, scheduling, coordinating and supervising the trade contractors
- Provides technical and clerical services in the administration of the project
Construction Management:
When is the budgeted construction cost realized as an actual cost?
When each tender package is released and sub contracts are awarded
Construction Management:
Why do architects/engineers typically decline to provide construction services?
The lack of experience or insurance. The CM typically assumes financial risk, once sufficient bids packages have been received and actual constructions costs are realized.
Construction Management:
What are the advantages of this project delivery method?
- CM has direct contractual relationship with the owner
- Advice on constructability and cost available to the design team
- Conducive to fast tracking (construction can start before design is complete)
- Costs can be monitored
Construction Management:
What are the disadvantages of this project delivery method?
- Added costs with the addition of another consultant
- More complex relationships means more complex modes of communication, more administrative costs
- Possibility of a conflict of interest if the CM is not a third party
- Less control of the final cost in an unstable market
Design-Build:
What defines this form of project delivery?
The owner contracts with a single entity that provides both design and construction services.
