Scheduling evaluation in construction projects using the critical chain project management method

Abstract

PT. A is a company engaged in construction, EPC (Engineering, Procurement and Construction), infrastructure investment, property and real estate. The case study that was raised in this study was the construction project of the retaining wall and the ABC dock that was carried out by PT. A. The problem in the project is that the project scheduling is not good, causing delays in project completion. The purpose of this research is to evaluate the scheduling of the project so that the optimum schedule can be obtained in project implementation. The method used in this study is Critical Chain Project Management (CCPM). CCPM is a project scheduling method that can optimize the schedule due to the absence of multitasking. The CCPM begins by estimating the time without safeguarding the existing time on each job by using the Cut & Paste Method. The critical path serves to find out the critical or non-critical work or activity. Critical activities on wall construction projects anchoring land and ABC dock namely work keep directors. Based on buffer consumption monitoring indicators due to the potential for the emergence of waste will end in use of project buffer duration consumed during the 19-35 period day and immediately take action if the buffer is consumed in the period of 36-53 days. Based on evaluation with critical application Project chain management obtained one feeding 4-day buffer and duration of the buffer project 53 days with the existing scheduling period 432 days to 379 days without buffer consumption.
