(2) The clause at 52.232-2, Payment under Fixed-Price Research and Development Contracts, in solicitations and contracts when a fixed-price research and development contract is contemplated;
(3) The clause at 52.232-3, Payments under Personal Services Contracts, in solicitations and contracts for personal services;
(4) The clause at 52.232-4, Payments under Transportation Contracts and Transportation-Related Services Contracts, in solicitations and contracts for transportation or transportation-related services;

The contracting officer shall ensure that the modification specifies the percentage and total amount of the withhold payment. Normally, there should be no need to withhold payment for a contractor with a record of timely submittal of the release discharging the Government from all liabilities, obligations, and claims, as required by paragraph (g) of the clause.
