Delay Analysis of Structural Work of Housing Project in Meruya (Indonesia) Using Critical Path Method

Project scheduling is one of the results of planning that can provide information about the planned schedule and project progress in terms of resource performance in the form of costs, labor, methods, equipment and materials as well as the planned project duration and time progress for project completion. The basis of this research is on the construction project of a single-story house (low-rise apartment) in Meruya, Indonesia, which consists of two buildings, each consisting of 7 main floors and a mezzanine floor. The purpose of this research is to analyze several types of work, especially in the main structure of the building that is in a critical time path and analyze the impact of work costs based on the development of planned and actual progress of the building structure work. The use of the Critical Path Method (CPM) is to develop a project schedule by identifying which tasks are critical. A questionnaire includes work delay factors in the project, for actions that can handle delay factors, and finally actions in handling work delays in the project by causal factors. From data analysis, it is discovered that the CPM network diagram can be used to check the possible ongoing delays by comparing the dates on the CPM to the current date. It can be caused by significant root factors of delays, so that the right corrective action can be done in the right time; the final result should be on time project.
