Design Bid Build

The design-bid-build project delivery method is the “traditional” means of delivering a construction project, which creates clear separation between the design and construction process.

In a design-bid-build project, the owner hires an architect or engineer (A/E) to create design documents including drawings and technical specifications for the project. In addition, the A/E will typically develop a project cost estimate and schedule. Once the design documents are completed, a Request for Bids is created and released to contractors.

Our firm, as contractor, will evaluate the project documents and provide a price for the HVAC work. The A/E is responsible for answering bidder questions and for assisting the owner in evaluating the received bids. Once a bid is selected, the owner establishes a contract with the chosen contractor and work begins on the project.

As the traditional means of completing projects, the design-bid-build method is the most familiar to those in the industry. It also has, in theory, the ability to deliver a low-cost project to the owner. However, since this method isolates the contractor from the design process, there is a high potential for project cost increases due to conflicts between the design documents and the constructability of the project in the field.
