Prepared by the Committee on Earth Retaining Structures of the Geo-Institute of ASCE. This Geotechnical Special Publication provides guidelines for the use of braces and tiebacks during excavations, focusing particularly on safety issues. When an excavation is made in soil or rock, materials adjacent to the cut face lose their natural lateral support. It them becomes necessary to support the excavation with braces and tiebacks, which provide the lateral restraint needed for safety. In addition to assisting engineers make essential safety decisions, this report provides information and conceptual orientation for owners, funding agencies, contractors, and engineering and architectural staff.
