The design-build approach (also known as EPC: Engineer-Procure-Construct) has the advantage of using our architectural and engineering teams to develop design criteria for a project, while our construction team uses subcontractors to provide pricing based on these criteria. This method allows for the development of a fixed price during earlier stages of a project. However, since pricing is developed based on design criteria—and not specific project details—there is limited control over installed materials, finishes, and equipment.
Using the DB method, a fixed project cost is developed after a portion of the design is complete, and a known project price is achieved earlier than with other methods. Since the project cost is fixed before the design is completed, it will contain contingencies to account for the portions of the project that are not fully designed. Thus, the fixed project cost may not always result in the best value for the project.
Since pricing is fixed before the design is completed, fewer options might be available at later stages of the project. This limits the ability to change the quality without changing the price.
A DB timeline focuses on developing a fixed price—instead of flexible design options—during the design process. This results in the design and pricing phases overlapping, thus providing a shorter overall timeline.
