GSA is proposing to amend the General Services Administration Acquisition Regulation (GSAR) to adopt an additional project delivery method for construction, construction manager as constructor (CMc). CMc is used in industry and allows for early industry engagement on construction contracts that provide schedule growth and administrative savings. The current FAR and GSAR lacks detailed coverage differentiating various construction project delivery methods. GSA’s policies on CMc have been previously issued through other means. By incorporating CMc into the GSAR and differentiating for various construction methods, the GSAR will provide centralized guidance to ensure consistent application of construction project principles across the organization. Integrating these requirements into the GSAR will also allow industry to provide public comments through the rulemaking process.
