Analysis of Project Time Acceleration Using the Crashing Method in the Construction of The Green Leaf Regency Shophouses, Surabaya

Abstract

Along with the development of the era, more and more construction projects are built to meet all human needs, ranging from residential homes to business places or public service places. The Green Leaf Regency Shophouse development project located on JL. Raya Pandugo No. 72, Surabaya, is one of the construction projects with a work volume of 4,410 m2, a contract value of Rp. 4,853,418,390.00, and a planned implementation time of 330 days or 11 months. The Green Leaf Shophouse Development Project is still 45% in progress. There is a project request to accelerate completion due to consumer pressure on the project owner, which is also a challenge in itself so that the handover can be carried out on time without any delays. This study uses the Crashing method to analyze the optimum Time and Cost due to Acceleration and determine Time and Cost Efficiency. Secondary Data is carried out through the collection of Project data in the form of RAB, AHSP and Time Schedule / S curve from the contractor of the Ruko The Green Leaf Regency Surabaya construction project that meets the criteria. Data is analyzed using the Crashing and Ms Project methods. Based on the analysis that has been carried out on the acceleration of the implementation time of the Ruko The Green Leaf Regency Surabaya construction project using the crashing method by adding overtime hours, the work that was accelerated to get the most optimal duration was the Pas Bata Ringan ex. Blesscon work. The results of the acceleration were 3 hours of overtime, namely 324 days, 6 days faster than the normal duration of 330 days. From the results of this analysis, a time efficiency of 1.8% was obtained. And the total cost of 3 hours of overtime was Rp. 4,847,386,076.73, which can save costs of Rp. 6,032,313.27 from the normal cost of Rp. 4,853,418,390.00. From the results of this analysis, a cost efficiency of 0.12% was obtained.
