(a) Every contract (and any bid specification therefor) entered into by the United States or the District of Columbia in excess of $2,500, except as provided in section 356 of this title, whether negotiated or advertised, the principal purpose of which is to furnish services in the United States through the use of service employees, shall contain the following:
(1) A provision specifying the minimum monetary wages to be paid the various classes of service employees in the performance of the contract or any subcontract thereunder, as determined by the Secretary, or his authorized representative, in accordance with prevailing rates for such employees in the locality, or, where a collective-bargaining agreement covers any such service employees, in accordance with the rates for such employees provided for in such agreement, including prospective wage increases provided for in such agreement as a result of arms length negotiations. In no case shall such wages be lower than the minimum specified in subsection (b) of this section.
(2) A provision specifying the fringe benefits to be furnished in the various classes of service employees, engaged in the performance of the contract or any subcontract thereunder, as determined by the Secretary or his authorized representative to be prevailing for such employees in the locality, or, where a collective-bargaining agreement covers any such service employees, to be provided for in such agreement, including prospective fringe benefits increases provided for in such agreement as a result of arms-length negotiations. Such fringe benefits shall include medical or hospital care, pensions on retirement or death, compensation for injuries or illness resulting from occupational activity, or insurance to provide any of the foregoing, unemployment benefits, life insurance, disability and sickness insurance, accident insurance, vacation and holiday pay, costs of apprenticeship or other similar programs and other bona fide fringe benefits not otherwise required by Federal, State, or local law to be provided by the contractor or subcontractor. The obligation under this subparagraph may be discharged by furnishing any equivalent combinations of fringe benefits or by making equivalent or differential payments in cash under rules and regulations established by the Secretary.
(3) A provision that no part of the services covered by this chapter will be performed in buildings or surroundings or under working conditions, provided by or under the control or supervision of the contractor or any subcontractor, which are unsanitary or hazardous or dangerous to the health or safety of service employees engaged to furnish the services.
(4) A provision that on the date a service employee commences work on a contract to which this chapter applies, the contractor or subcontractor will deliver to the employee a notice of the compensation required under paragraphs (1) and (2) of this subsection, on a form prepared by the Federal agency, or will post a notice of the required compensation in a prominent place at the worksite.
(5) A statement of the rates that would be paid by the Federal agency to the various classes of service employees if section 5341 or section 5332 of title 5 were applicable to them. The Secretary shall give due consideration to such rates in making the wage and fringe benefit determinations specified in this section.
(b) 
(1) No contractor who enters into any contract with the Federal Government the principal purpose of which is to furnish services through the use of service employees and no subcontractor thereunder shall pay any of his employees engaged in performing work on such contracts less than the minimum wage specified under section 206 (a)(1) of title 29.
(2) The provisions of sections 352 to 354 of this title shall be applicable to violations of this subsection.
