Box Girder Construction on Toll Road Project use Manual Program Evaluation and Review Technique (M-PERT) and Value Engineering (VE) to Performance Cost and Time Improvement

Abstract

Indonesia's ranking is 72 out of 141 countries and is in 5th place in the group of countries in Southeast Asia based on the 2019 Global Competitiveness Index (GCI) by the World Economic Forum. The current development of infrastructure development is not directly proportional to an increase in the number of infrastructure users by 1.9% from an annual increase of 10%-55%. And the occurrence of implementation time experienced a delay of 11.95%. And with a low rate of return on books with high investment costs in the construction of 7.79%. The expected goal in this research is to have cost and time efficiency in implementing infrastructure development. In this study, the focus is on the upper structure work, one of which is the box girder, to improve time and cost efficiency based on the Manual Program Evaluation and Review Technique (M-PERT) and Value Engineering (VE) in the case study of this research. The case study using the M-PERT method resulted in a time efficiency value of 98.87% of the completion time at the job site, while the VE method obtained an added value of income outside toll roads of 9.38% of construction costs.
