Presents formwork standards and guidelines based on safety, quality, and economy and recognizing that 35 to 60 percent of the total cost of the concrete work in a project in the United States may be in the formwork. A section is devoted to contract plans and specifications noting the kind an amount of specification the engineer/architect should provide the contractor. Since the committee concludes that formwork design as well as construction must be the responsibility of the contractor, the recommendations contained in the standard are directed to that group. This standard, then, presents recommended practices for formwork and suggests criteria for assuring proper performance. Engineers and architects must note that this standard, ACI 347, is not written in specification language and should not be used as a reference specification. However, an understanding of these recommendations by engineers and architects will greatly aid these groups in the preparation of their specifications. The report is divided into six chapters: (1) introduction; (2) design; (3) construction; (4) materials for formwork; (5) forms for special structures; and (6) formwork for special methods of construction.
