"Question Number 1: Regarding the PROJECT MANAGEMENT & SUPPORT SERVICES (Defined Pool) contract, if a SBE firm is a sub consultant/contractor to a design firm or a supplier, is that firm precluded from proposing and performing work as a prime contractor for the Defined Pool contract?
Answer: No, the firm may propose as a prime contractor for the defined selection pool contract. However, if proposing as a prime the work cannot be self performed. The SBE prime MUST select/solicit other SBE certified sub consultants to perform the actual work.
