Field Manual: Safety Evaluation of Buildings after Windstorms and Floods

Product Code/ISBN: ATC45

This guide will help you assess whether buildings that are damaged or potentially are damaged can still be used or if they need to be restricted. This is a perfect help guide for building inspectors, engineers, or any other field that checks the safety of buildings. All the information is presented to you in a handy pocket guide format.
