Activity Overlapping Technique for Early Completion of Construction Project

Abstract

Abstract: An effective and well-known method for the early completion of construction projects is the overlap of the project’s critical activities or phases that would normally be carried out in sequence. The overlapping technique reduces the project completion time with a minimum cost overrun. Overlapping is also called a fast-tracking mechanism. It is risky because it increases the probability of rework resulting in increasing the cost of the project. The Overlapping in construction projects must be carried out effectively because each pair of activities cannot overlap, since some previous activities may not allow overlap due to maximum rework. Various overlapping strategies exist in a construction project which all can result in time-saving. so, the cost of these strategies varies significantly depending on the overall Rework. A favorable overlapping strategy leads to minimal time savings costs. To find such a strategy, the question arises: “Which activities have to be overlapped and to what extent to reduce the project duration at the minimum cost?” This study addresses the question and generates an Overlapping Decision algorithm.
