ASCE 71-21 is a standard prepared by the Standards Committee for Identifying, Quantifying, and Proving Loss of Productivity of the Construction Institute of ASCE. The standard emphasizes the importance of labor costs in construction projects and provides guidance on tracking and measuring labor productivity to prevent, mitigate, and recover cost overruns. It also addresses the increasing frequency and magnitude of loss of productivity disputes and claims.

The standard covers various topics related to productivity, including defining productivity and related terms, preparing, collecting, validating, and analyzing productivity data, detecting disruptive events, preferred methodologies for quantifying productivity loss, and strategies to avoid conditions that create productivity loss.

ASCE 71-21 is intended for a wide range of professionals involved in construction projects, including owners, designers, contractors, attorneys, mediators, triers-of-fact, educators, and researchers. It is applicable to different project types, such as construction-only, design-only, and design-construct projects, as well as projects of varying sizes, public and private work, and international and domestic contexts. The standard aims to provide a comprehensive framework for identifying, quantifying, and proving loss of productivity, facilitating better project management and dispute resolution.
