The contracting officer representative (COR) will not certify an invoice for payment on a competitive SDVOSB set-aside for the paving of a large parking lot on a military installation because the prime SDVOSB subcontracted 95% of the work to another similarly situated SDVSOB concern. The rationale is that the contractor violated the Limitations on Subcontracting clause in the contract.

Is the COR correct?Explain?
