ASCE is conducting a public comment period on the update to ASCE/CI 71-XX Identifying Quantifying and Proving Loss of Productivity. The public comment period will be held from June 12, 2019 to July 29, 2019.  

Managing labor productivity is a crucial component of project success. Because labor costs are typically the most variable and a major component of overall project cost, tracking and measuring labor productivity is helpful in preventing, mitigating, and recovering cost overruns. The numerous published treatises and studies on loss of productivity in the construction industry highlight its importance. Despite that importance, there are inconsistencies in the methodologies used to identify, quantify, and determine causation and liability for labor productivity losses.

Compounding this lack of consistency is the fact that loss-of-productivity disputes and claims are increasing in frequency and magnitude. An additional characteristic of loss of productivity claims is that they can be quite complex for many reasons, including the fact that the lost labor-hours are inseparable from the original contract labor-hours. Thus, there is a need to establish standards for the reliable identification and quantification of productivity loss, followed by the determination of causation and liability for that productivity loss. This standard presents such key principles for identifying, quantifying and proving loss of productivity.
