Abstract: Loss of labor productivity is one of the most prevalent types of damages found in construction claims and also one of the most difficult to compute and prove. Construction projects are heavily labor based along with the materials and equipments. Therefore, the utmost attention has to be given to handle the effective labor productivity. When the expected labor productivity is adversely affected, there is an immediate impact upon the time required to carry out the affected tasks with a consequent impact, which may be substantial, upon the costs of the operations. A contractor’s difficulty arises from the need to demonstrate the labor productivity coefficients used for the bid / contract price and the impact upon these productivity coefficients of the external influencing events. Once this is demonstrated, the contractor must also prove that the external influence entitles him to claim the costs of the loss of productivity. Many projects are not completed on scheduled time and within the budget cost. There are some circumstances where the project exceeds the budget and is not delivered on time due to the various factors affecting labor productivity. This thesis exhibits the various types of factors that are affecting labor productivity. The project manager should be aware of various factors which could affect directly or indirectly the labor productivity at construction sites and then identify the ways to control loss of labor productivity or improve the labor efficiency by using the various methods of motivation for the employees. During the execution of the contract, a project may get many changes affecting labor productivity such as additional works to the original contract, modification works and re-works. Hence, the project manager should clearly identify such changes and notify them to the Quantity Surveyors or Cost Engineers, in order to decide whether to claim the costs of the changes done or whether to absorb the cost if it is a re-work. This thesis also exhibits the various methods of calculating the loss of productivity which can be used to support a claim for non-productive labor hours due to an owner caused delay.
