8. Either all contractors making up a joint venture or the joint venture itself must hold certificates of responsibility prior to submitting a bid or being awarded a contract. When the joint venture itself does not hold a certificate of responsibility, then all parties to the joint venture must hold certificates of responsibility and each must have the proper classification for the project to be awarded prior to submitting a bid or being awarded a contract. Accordingly, contractors engaging in a joint venture should not perform work that exceeds the statutory scope of their certificate(s). (See AG Opinion December 3, 1990 to Harper, and AG Opinion dated April 5, 1991 to Cardin.) When a joint venture submits a bid on a public project in excess of Fifty Thousand Dollars ($ 50,000.00), and the joint venture itself does not hold a certificate of responsibility, each contractor comprising the joint venture shall place its certificate of responsibility number on the outside of the envelope containing the bid as set forth in Miss. Code Ann. § 31-3-21(2), as amended. If the joint venture itself holds a certificate of responsibility, then it shall place its certificate number only on the outside of the envelope.
