          CHAPTER 1--FEDERAL ACQUISITION REGULATION (CONTINUED)
 
Sec. 52.236-2  Differing Site Conditions.

    As prescribed in 36.502, insert the following clause:

                  Differing Site Conditions (APR 1984)

    (a) The Contractor shall promptly, and before the conditions are 
disturbed, give a written notice to the Contracting Officer of (1) 
subsurface or latent physical conditions at the site which differ 
materially from those indicated in this contract, or (2) unknown 
physical conditions at the site, of an unusual nature, which differ 
materially from those ordinarily encountered and generally recognized as 
inhering in work of the character provided for in the contract.
    (b) The Contracting Officer shall investigate the site conditions 
promptly after receiving the notice. If the conditions do materially so 
differ and cause an increase or decrease in the Contractor's cost of, or 
the time required for, performing any part of the work under this 
contract, whether or not changed as a result of the conditions, an 
equitable adjustment shall be made under this clause and the contract 
modified in writing accordingly.
    (c) No request by the Contractor for an equitable adjustment to the 
contract under this clause shall be allowed, unless the Contractor has 
given the written notice required; provided, that the time prescribed in

[[Page 288]]

(a) above for giving written notice may be extended by the Contracting 
Officer.
    (d) No request by the Contractor for an equitable adjustment to the 
contract for differing site conditions shall be allowed if made after 
final payment under this contract.

                             (End of clause)
