![]() ![]() For example, use of the actual or achieved production information of the same or similar work on the same project eliminates from consideration problems for which the contractor would be responsible such as errors in the bid, deficiencies in labor and management, equipment problems, etc. Well, it’s because the contractor’s achieved productivity removes variables or problems in the source data that could affect the accuracy of the analysis. Why is the “actual or achieved productivity” feature of a measured mile method so important? ![]() The reason that this method is the preferred is because of its reliance on the actual or achieved productivity. This inefficiency factor represents the percent of lost productivity in the impacted period as compared to the unimpacted period. The two periods of performance are called the unimpacted (efficient) and impacted (inefficient) periods.Ī comparison of the productivity in the unimpacted and impacted periods will result in the calculation of the inefficiency factor, which is the productivity of the unimpacted period minus the productivity in the impacted period divided by the productivity in the unimpacted period (U-I/U). The measured mile method compares the achieved productivity of two periods of performance for the same operation on the same project. The preferred method, as determined by courts and triers of fact, for measuring lost productivity or inefficiency is the measured mile. Comparing Actual Productivity to the Contractor’s Bid or Estimate.Comparing Actual Productivity from the Subject Project to Different Project.And we’re going to discuss five of those methods, in the following descending order of preference: In this Ideas & Insights, we’re going to discuss methods for measuring lost productivity or inefficiency. ![]()
