HB 3563 introduces the Construction Manager-General Contractor (CMGC) method as an alternative procurement strategy for transportation-related construction projects. The method involves contracting separately with an engineer for design and a construction manager to serve as the general contractor, offering consultation during design and construction phases. The Texas Department of Transportation and local transportation authorities may use this approach, bypassing certain traditional procurement requirements. The bill mandates a structured selection process, including evaluation teams, weighted criteria, and negotiation phases. It specifies the roles and responsibilities of engineers and construction managers, requiring public disclosure of selection rankings and independent cost validation. Performance and payment bonds are required within ten days of contract award.
