AASHTO CHBTW-2, Construction Handbook for Bridge Temporary Works, Second Edition (2017), is a construction-oriented companion to the Guide Design Specifications for Bridge Temporary Works. Sections cover introduction, falsework, formwork, and temporary retaining structures. Falsework is treated through materials and manufactured components, foundations, construction methods, loading, and inspection. Construction topics include wood construction, vertical shoring systems, cable bracing, bridge deck falsework, and traffic openings, and inspection is described both during and after concrete placement. Appendices give section properties of dressed and rough sawn lumber, worked design examples for slab falsework, needle beams, pier cap vertical formwork, wind load on falsework, and falsework cable bracing, along with recommended thicknesses of wood lagging and steel sheet pile data. The handbook is intended for contractors and construction engineers engaged in bridge construction.
