Time Cost Trade Off Analysis on the Trainning Center Project PT. X With Additional Working Hours

Abstract

In the world of construction the most common problem is delays in project implementation. To overcome this problem, several alternatives for project acceleration are used, such as additional overtime hours, additional workforce, changes in working methods that are faster, use of materials with faster installation, and use of more productive heavy equipment. The object of this research is the PT. X. Acceleration is carried out using the time cost trade off method with the addition of overtime working hours on structural work that is on the critical path. The purpose of this study is to determine the level of increase in project costs due to overtime activity and time acceleration generated by using this method. The results of cost calculations by accelerating through additional working hours obtained the shortest project duration, namely for 112 days from the total project completion plan for 150 working days with an increase in costs of Rp. 53,967,111.00 so that the total cost becomes Rp. 8,813,167,113. Or 0.62% more expensive than the planned budget under normal conditions, namely Rp. 8,759,200,000.00. From the results of these studies, it can be concluded that the addition of overtime working hours can accelerate the project duration and increase the total project budget costs that must be spent. 62% more expensive than the planned budget under normal conditions, namely Rp. 8,759,200,000.00. From the results of these studies, it can be concluded that the addition of overtime working hours can accelerate the project duration and increase the total project budget costs that must be spent. 62% more expensive than the planned budget under normal conditions, namely Rp. 8,759,200,000.00. From the results of these studies, it can be concluded that the addition of overtime working hours can accelerate the project duration and increase the total project budget costs that must be spent.
