D.C. Mun. Regs. tit. 27, § 3600
3600.1 Only a contracting officer acting within the scope of the contracting officer's delegated contract authority is authorized to execute a contract modification on behalf of the District. Other District personnel shall not do any of the following:
(a) Execute contract modifications;
(b) Act in a manner that causes a contractor to believe that they have authority to bind the District; or
(c) Direct or encourage a contractor to perform work that should be the subject of a contract modification.
3600.2 A contract modification, including a change issued unilaterally by the District, shall be priced and a government estimate shall be prepared before signature by the parties, unless the interests of the District would be adversely affected. If a significant cost increase could result from a contract modification and time does not permit negotiation of a price, the contracting officer shall negotiate a maximum contract price increase and include that price in the modification.
3600.3 If an unpriced contract modification is issued, the contracting officer shall justify in writing the reasons for the issuance of the unpriced modification.
3600.4 The contracting officer shall not execute a contract modification, including a change order, which causes or will cause an increase in the funding level of the contract without having first obtained a certification of the availability of funds. The certification shall be based on the negotiated price or the negotiated maximum price.
3600.5 A modification to a contract may be executed without having first obtained the certification required under §3600.4 if the modification includes a clause, approved by the Director, which conditions payment upon the availability of funds.
3600.6 The Director shall review contract modifications as required in chapter 10 of this title.
AUTHORITY: Unless otherwise noted, the authority for this chapter is the District of Columbia Procurement Practices Act of 1985, D.C. Law 6-85, as amended, D.C. Code §1-1181.1 et seq. (1981).
