The only current U.S. standard for foundations and excavations is ANSI Standard A.56 which was adopted in 1952 and is now considered by the profession to be obsolete. The ASCE, sponsor of Standard A56 is now preparing a new standard for foundations and excavations. The work is being prepared under the ASCE-COS Committee for Foundations and Excavation Standards which is organized to comply with consensus requirements as required by ANSI. The first draft of the standard which will be submitted to the committee for consideration is being prepared under the direction of the National Bureau of Standards with the assistance of a professional working group. Funding is provided by the Department of Housing and Urban Development. It is planned to write the standard as a performance standard which will contain performance criteria design limit states and specific (prescriptive) provisions. The prescriptive provisions will not be mandatory if the performance criteria are otherwise satisfied. Thus the constraints, at times caused by prescriptive code provisions, will be minimized.
