Have AASHTO (American Association of State Highway and Transportation Officials) and FHWA (Federal Highway Administration) endorsed ASCE 38-02?
Yes. AASHTO’s most current edition of A Guide for Accommodating Utilities Within Highway Right-of-Way states that: “Underground utilities should be accurately located using the American Society of Civil Engineer’s Standard Guidelines for the Collection and Depiction of Existing Subsurface Utility Data where the exact location of underground utility infrastructure is required. The survey information should be developed early in the design process so that the designer can show on the plans the accurate location of underground utilities that cause injuries and property damage.” The FHWA’s utility regulation, 23 CFR 645, recommends the use of the current edition of AASHTO’s A Guide for Accommodating Utilities Within Highway Right-of-Way and the FHWA memorandum that transmitted the most recent version of this document it to the field encouraged its use. This constitutes both AASHTO and FHWA endorsement of ASCE Standard 38-02.
