Guidelines for the Design and Erection of Formwork, Falsework and Temporary Structures (First Revision)
IRC 87 (2011) provides comprehensive guidelines for the design, erection, and safe use of formwork, falsework, and temporary structures in civil engineering projects, particularly in road and bridge construction. It addresses material selection, load considerations including vertical, horizontal, seismic, and environmental loads, and emphasizes safety during construction, stripping, and re-shoring. This standard is essential for engineers and contractors involved in planning and executing temporary structural supports to ensure structural integrity and worker safety.
