Construction Program Guide

Contract Time

The FHWA's policies for construction time and time extensions provide for their use and for the review and approval of time related contract modifications for Federal-aid participation.

Authority/Legal Basis

  • 23 USC 315 Rules, regulations, and recommendations (2012) provides very broad authority for the Secretary of Transportation to prescribe regulations to carry out the Federal-aid highway program. However, there are no specific statutes dealing with construction contract modifications other than the required use of standardized changed conditions clauses as required by 23 USC 112(e).

The above regulations provide the FHWA's regulatory policy regarding construction contract modifications. However, please note that these regulations were last updated on August 2, 1991 and do not include revised stewardship, oversight, and applicability requirements resulting from the 1991 ISTEA and the 1998 TEA-21. See the discussion in the FHWA Contract Administration Core Curriculum Manual for a summary of current FHWA policy).
