ACI has published the “ACI 347R-03 Guide to Formwork for Concrete.” Highlights of this publication include a section on contract documents that explains what specification guidance the engineer/architect should provide for the contractor, and another section that advises the formwork engineer/contractor on the best ways to meet the specification requirements safely and economically. Separate chapters deal with design, construction and materials for formwork, with special considerations to architectural concrete, bridges, shells, mass concrete and underground work. The concluding chapter on formwork for special methods of construction includes slipforming, preplaced aggregate concrete, tremie concrete, precast, and prestressed concrete.
