AASHTO GSBTW-2-I1, Guide Design Specifications for Bridge Temporary Works, 2nd Edition (2017), addresses the design and construction of falsework, formwork, and related temporary works for bridges. Section 1 provides the introduction, scope, related publications, definitions, and metric conversions. Section 2 covers falsework, including falsework drawings, materials and manufactured components such as structural steel and wood, loads and load combinations for dead, live, construction, and environmental loads, and design considerations including deflection, slenderness, overturning and sliding, steel beam grillages, proprietary shoring systems, and traffic openings. Foundation provisions address footings, pile foundations, and foundations for heavy-duty shoring systems. Section 3 begins the formwork provisions covering materials and form accessories. The specifications provide both load and resistance factored design and allowable stress design approaches. Contractors and bridge designers can use the specifications for temporary works on bridge construction projects.
