OPTIMALISASI PENJADWALAN PROYEK JEMBATAN GIRDER GUNA MENCAPAI EFEKTIFITAS PENYELESAIAN DENGAN METODE PERT DAN CPM PADA PT BUANA MASA METALINDO

Abstract

PT Buana Masa Metalindo focuses on providing metal fabrication for various industrial sectors, such as
oil, gas, mining, industry and automotive. The current ongoing project is girder bridge. A girder bridge is
a high quality light steel frame bridge, which is movable and is very strategic in supporting construction
works. The issue lies on the project timefram which can be finished in accordance to the time shift set at
42 days in the beginning, to 35 days. PERT-CPM method can be utilizied to manage project working time
become more efficient and effective. In order to reduce the impact of the project delay and cost overruns,
three alternative methods can be drawn; (i) additional workforce/labours, (ii) working overtime, and (iii)
subcontracting. Acceleration of duration is done on the activities at the critical path and total days that
given on each alternative is equaled. Result showed that additional workforces/labours alternative
figured out the optimal time to finish the project which 35 days with projects total cost Rp48,650,000.00.
