(1) WSSC shall implement policies and procedures to ensure prompt and full payment to WSSC-approved SLBEs and MBEs. Prime contractors awarded WSSC contracts shall ensure the prompt and full payment of any subcontractors working on the contract. During the contract and upon completion of the contract, WSSC may request documentation to certify payment to subcontractors or suppliers. All WSSC contracts shall include a contract clause to require prime contractors to: pay subcontractors for satisfactory performance of their contracts no later than 15 days of subcontractor’s invoice on WSSC-funded contracts; and pay subcontractors retainage within 15 days after the subcontractor’s work is satisfactorily completed. All payments to direct subcontractors must be reported and validated by the prime contractor and direct subcontractor in WSSC’s Web-Based Compliance System within 30 days of the prime contractor being paid by WSSC.

(2) A subcontractor’s work is satisfactorily completed when all the tasks called for in the subcontract have been accomplished and documented as required by the prime contractor. When a prime contractor has made an incremental acceptance of a portion of the work of a subcontractor covered by that acceptance, it is deemed to be satisfactorily completed.

(3) WSSC shall establish appropriate means for enforcement which may include appropriate penalties for failure to comply.

(4) Prime contractors shall permit the Washington Suburban Sanitary Commission to conduct audits of WSSC-funded contracts that contain SLBE or MBE subcontracting requirements in accordance with WSSC 6.15.450.
