Loss of Productivity can be one of the most challenging damages to credibly establish in a construction claims matter. Its foundation relies on the assertion that the work could have been performed at a better level of production, absent the claimed impacts and/or delays. There are numerous publications and opinions on how this can be established. However, all of these rely on similar strategies in that the contractor must first establish the attainable level of production that should have been achieved on the project. Then the contractor must prove that the Loss of Productivity resulted from impacts that were out of the contractor’s control and unforeseen as part of the original contract. This could include acceleration changes, defective engineering, excessive overtime, supplier delays, labor relations factors, extreme weather, among other factors and the ripple effect. Finally, the contractor must be able to calculate, with a reasonable degree of accuracy, the actual losses sustained.
