2.  Inclusion of FAR 52.246-6(f) Provision

Comment: A respondent stated that the proposed rule should include consideration of the provision found at FAR 52.246-6(f), Inspection--Time-and-Material and Labor-Hour, paragraph (f) (requirement to replace or correct services or materials that failed to meet contract requirements).

Response: This comment is outside the scope of this case, which was limited to simply clarifying the existing prescriptions and clauses relating to appropriate payment provisions for use in time-and-materials and labor-hour contracts. Inclusion of FAR provision 52.246-6(f) language into the payment provisions at FAR 52.212-4, 52.216-7, or 52.232-7 is unnecessary.3. Consistency Between Revised Clauses

Comment: A respondent cited several instances where language was inconsistent between the clauses under the proposed rule. Specifically, the proposed rule aligned the frequency of invoicing and the period for submission of the completion voucher provisions for time-and-materials contracts at FAR 52.232-7 with that currently set forth in the "Allowable Cost and Payment" clause at FAR 52.216-7. However, for labor-hour contracts, under Alternate I to 52.232-7, the proposed rule left the invoicing and period for submission of the completion voucher provisions, which were different from the requirements set forth in FAR 52.216-7 and 52.232-7, unchanged. The respondent questioned this inconsistency regarding these provisions.

Response: The invoicing and submission of the completion voucher provisions in time-and-materials contracts and labor-hour contracts should align. Consequently, the final rule does not include the proposed rule language regarding invoicing and the period for submission of completion vouchers for labor-hour contracts in Alternate I to FAR clause 52.232-7.
