Design-bid-build

Definition

Design-bid-build is a traditional project delivery method where the design and construction phases of a project are separated. In this approach, an owner first hires a designer to create the project plans, then puts the project out for bids to contractors, and finally selects one contractor to build it based on their bid. This method emphasizes distinct roles for designers and builders, impacting contracts and legal relationships throughout the project lifecycle.

5 Must Know Facts For Your Next Test

1. Design-bid-build is one of the oldest and most common project delivery methods used in construction.
2. In design-bid-build, the owner has more control over the design phase as they can work directly with the designer before involving contractors.
3. This method can lead to longer project timelines since each phase must be completed before moving to the next.
4. It often results in lower initial costs for the owner since multiple bids can be compared before selecting a contractor.
5. However, design-bid-build can create adversarial relationships between contractors and designers due to the separation of roles.

Review Questions

• How does the design-bid-build method affect the roles of owners, designers, and contractors during a construction project?
  • In the design-bid-build method, owners maintain significant control during the design phase by working closely with designers to establish project specifications. Once designs are completed, contractors are invited to bid on the construction phase, creating a competitive environment for cost estimation. This separation of roles means that any issues arising during construction may lead to conflicts between contractors and designers since they operate independently.
• Discuss the advantages and disadvantages of using design-bid-build compared to alternative project delivery methods like design-build.
  • Design-bid-build offers advantages such as clear delineation of responsibilities and potentially lower initial costs due to competitive bidding. However, it can result in longer timelines due to sequential phases and may foster adversarial relationships. In contrast, design-build combines design and construction under one contract, which can enhance collaboration and speed up delivery but might limit owner control over design decisions.
• Evaluate how legal issues might arise in design-bid-build projects and what steps can be taken to mitigate these risks.
  • Legal issues in design-bid-build projects often stem from disputes between owners, contractors, and designers regarding scope changes, delays, or cost overruns. To mitigate these risks, parties can implement comprehensive contracts that clearly outline expectations, responsibilities, and processes for handling disputes. Regular communication among all stakeholders during each phase can also help identify potential conflicts early on, allowing for timely resolution before they escalate into legal challenges.
