D.C. Mun. Regs. tit. 19, r. 19-4352
The architect-engineer firm shall be responsible for the professional quality, technical accuracy, and coordination of all services required under its contract. The firm shall be liable to the Library for costs resulting from errors or deficiencies in designs furnished under its contract.
When modification of a construction contract is required because of an error or deficiency in the services provided under an architect-engineer contract, the CCO shall determine the extent to which the architect-engineer may be liable.
If the CCO determines that the firm is liable, and the recoverable cost will exceed the administrative cost involved or collection is otherwise in the best interests of the Library, the CCO shall initiate procedures to collect the amount due.
The CCO shall prepare a written statement of the reasons for the decision whether or not to recover costs from the firm and place in the contract file.
