Construction Schedule Management for Densely Populated Areas Using CPM-Crashing

Abstract

Construction work in densely populated areas faces various challenges in its implementation. The impacts caused include buildings and residences in the vicinity often damaged due to the development of socio-economic activities in the environment. The safety of residents can also be threatened due to the use of heavy equipment and other environmental impacts. These things require the project to be implemented as soon as possible. This research aims to analyze the application of the crashing method in canal construction projects in densely populated areas. This research uses a quantitative approach to analyze the effectiveness of the Crashing method in implementing construction projects. Quantitative data regarding project time, costs, and activities. Each of the three acceleration alternatives is scheduled to be completed in 30, 45, and 60 days sooner. The best alternative is then chosen after obtaining the acceleration costs. As a result of this research, dependable actions can be planned to be carried out to speed up the project. Project acceleration has three times the alternative of thirty, forty-five, and sixty days. The findings show that the 60-day acceleration is worthwhile, with an additional cost of IDR. 46,709,624 was considered when calculating the slope costs. This is seen by the percentage of additional expenses, which grew by only 2.2% from the initial costs but accelerated to 33.3% of the planned timeline. The research results reveal the effectiveness of CPM-crashing techniques for projects in densely populated areas and can be used to develop measures for reducing potential dangers.
