Constructability Reviews

The primary goal of the constructability review process is to minimize the number of design-related issues encountered during construction. The review process effectively keeps the number of contract change orders (CCOs) and delays to a minimum, thereby maintaining schedule and budgetary goals. Two main questions must be answered in a constructability review: is the project buildable; and is it biddable?

Constructability review is an iterative process that usually occurs at the 30%, 70%, and 100% complete project stages. The initial review is conducted early in the process—typically in the planning phase—to verify that the project has been properly scoped and that major issues are being addressed. At the intermediate review—typically in the preliminary design phase—the focus shifts towards ensuring that the project is buildable. At the final review, the design is complete, and the focus of the review is now to ensure that the project is biddable. Depending on the individual project, input from several County departments may be required, including CIP Design, Wastewater Management, Field Operations, Landfill Management, Traffic Engineering, Environmental Services, Flood Control Engineering, and Materials Laboratory.
