Optimization of Orifice Metering Station Construction with Time Cost Trade off Methods

Abstract

Delay is a common problem in project. In case of building project, the delay in project completion means that the user has to pay penalty corresponding to contractual agreement with the host. The construction of the Seberida Metering Station Engineering Procurement Construction and Commissioning (EPCC) project has been delayed. Based on the project's physical progress scheduling report. The user demanded by the host to complete the project on time. One solution that can be done to overcome the project delay is to accelerate the duration of the project. However, the acceleration of the duration must be carefully calculated so that the project can be completed on time and the additional costs incurred as a consequence of reducing the duration do not swell. This Research uses the Time Cost Trade Off (TCTO) method as a solution to overcome delays, namely the method of scheduling projects by exchanging time and costs. From the results of the analysis with the Time Cost Trade Off method, it was found that the construction of the Metering Station was accelerated for 50 days, from the total duration of the project which normally takes 180 days to 130 days with an additional cost of $ 80,047.01.
