Scheduling of Infrastructure Construction Projects Using the Manual-Program Evaluation and Review Technique (M-Pert) Method Case Study: Indonesian Sunda Strait Bridge

Abstract

The idea to build the Sunda Strait Bridge, popularly known as Jembatan Selat Sunda (JSS), began in the government of Indonesia's first president, Sukarno, which connect two islands with the largest economy in Indonesia, Sumatra Island and Java Island. This ambitious project will become a single mega infrastructure project with the largest investment in Indonesia. The successful completion of a project can be associated to the completion of a project on time. Accurate calculation of project time duration estimation is the key to the success of an infrastructure project delivery on time. Many practitioners in construction industry nowadays are having difficulties to estimates project duration correctly. Choosing the appropriate method in scheduling planning is the key to the successful estimation of a project. This research proposes the use of the M-PERT scheduling method which is the development of the conventional PERT with a higher degree of accuracy. As a case study, this research uses the Suspension Bridge section, which is one part of the overall phase of the construction of the JSS infrastructure project. The results of this research produce estimates of the project duration using M-PERT is 2104.38 days. It gives the estimation error is less than 1% when compared with the Monte Carlo simulated curves. As a comparison, this research also calculates duration estimation using conventional PERT and it gives 2013 days with error more than 24% when compared with the Monte Carlo simulated curves. A step-by-step process to estimate project duration using M-PERT method are also include in supplemental data.
