Chapter 4 of ACI 347R-14, Guide to Formwork for Concrete (PDF)

Pdf Summary

The ACI 347R-14 Guide to Formwork for Concrete provides comprehensive guidelines prioritized towards safety, quality, and economy in construction formwork. It addresses the specific needs of engineers, architects, and contractors involved in designing and executing formwork structures. Here are some key components of the guide:

1. <strong>Contract Documentation</strong>: The guide emphasizes the importance of contract documents specifying the type and amount of formwork needed. These documents are essential for providing clear guidance and expectations to contractors.

2. <strong>Detailed Chapters</strong>: Various chapters cover critical topics such as formwork design, construction, materials, and considerations specific to architectural concrete. There are dedicated sections for bridges, shells, mass concrete, and underground work.

3. <strong>Design Criteria</strong>: It advises on the necessary design criteria, including vertical and horizontal loads, construction loads, safety factors, and material properties. Planning for formwork should consider load shifts, member capacities, and the overall stability of structures.

4. <strong>Construction and Safety</strong>: Guide details best practices for construction activities, including setup, safety precautions, construction practices, tolerances, inspection, and the removal of forms and supports.

5. <strong>Materials and Special Structures</strong>: Discusses the properties of formwork materials and considerations for special structures like bridges and long-span roofs. Also includes guidance for special construction methods like slipforming and the use of precast concrete.

6. <strong>Responsibility and Review</strong>: While the guide delegates the responsibility of design and construction to the formwork engineer/contractor, it stresses the need for review and approval by relevant authorities to ensure compliance and safety.

The document is directed at professionals competent to apply these guidelines responsibly, understanding the scope and limitations. It disallows casual referencing in contract documents unless restated in mandatory language for official incorporation by architects or engineers.
