Changed Conditions Clause in Construction Contracts

In the administration of construction contracts, there is usually a provision for dealing with changed conditions. Ten elements that should be included in a changed condition clause are recommended. Some widely used changed conditions clauses are analyzed, and their strengths and deficiencies are noted. A model clause for use in construction contracts is then drafted. This clause contains all the ideal elements of a changed condition clause. It is based, in part, on the recommended clause of the Committee on Contract Administration, ASCE, and, in part, on the papers presented in the 1963 seminar on Who Pays for the Unexpected in Construction, held by the Metropolitan Section, ASCE, in New York, N. Y.
