The Effect of Overtime Hour to Charge with Time Cost Trade Off Analysis

Abstract

A solution that can be implemented if it has been a delay is done accelerating the implementation of the additional hours worked. To perform the analysis of additional hours worked by the costs incurred can be carried out by the method of Time Cost Trade Off Analysis .. The point is to accelerate project implementation time of analyzing the extent to which time can be shortened by increasing the costs of the activities that can be accelerated execution time. Projects are chosen the library and archives building Batang district because of the demand on the part of the contractor to accelerate project completion time of a plan that is already listed in the contract due to the delay in the work. With limited resources, the acceleration of the project is carried out by working overtime for 3 hours a day. Crashing the work done on the items contained in the critical path of the job starts with the smallest cost slope. Compression is performed directly to lead to increased costs and reduced indirect costs. From the calculation, the critical time for 52 days (<9 weeks), or 10 days earlier than the normal time is 62 days, an increase in Rp6.746.451,21 from fixed costs Rp91.259.054,91 to Rp98.005.506,12. Then the variable cost for 24 days of overtime for a total of Rp11.023.213,87. So we get the total job costs Rp109.028.713,87.
