Abstract

UrbanTown Serpong is an integrated vertical residential area developed in the buffer zone of the capital city, business and industrial center, and connected to mass transportation facilities. Which carries the concept of integrated entrepreneurship with many supporting facilities. However, not all construction projects can be completed on schedule. There are several delay factors that can occur, such as caused by time estimation; improper management; material problems; labor; equipment; finance; and an unsupportive environment. This study aims to determine the dominant factors that cause delays during construction and solutions to prevent delays in the development of the UrbanTown - Serpong Project. The factor analysis uses the Importance Index (IMPI) method to assess which factors are classified as high in the project. The results of the study indicate that there are 4 out of 31 indicators that have a significant effect on the factors causing work delays, including: constrained by labor shortages; the work is not carried out with the correct method; lack of material; and owner delays in making decisions.

Abstract

In planning a building or infrastructure, various methods and strategies are needed to achieve the target for timely completion, resulting in a strong and beautiful quality building. Structural components such as foundations, columns, beams, and plates play an important role in supporting the establishment of a building. To produce the quality of the structural components required special skills in doing the job. Formwork has an important value as a mold (formwork) to form the dimensions of the structural components that have been planned. In this study, we will discuss the comparison of usage related to the cost and time of using different column formwork, namely semi-system formwork and aluminum formwork used to build multi-storey buildings. From the two types of formwork, the budget for formwork work will be analyzed to obtain an economical budget and efficient time. The comparative analysis of formwork semi system and formwork aluminum get results, for formwork semi system requires a cost of Rp. 1,366,460,000 with an implementation time of 35 days while using aluminum formwork is Rp. 1,114,460,000 with an implementation time of 20 days. This means that using semi system formwork is more expensive by Rp. 252,000,000 compared to semi system formwork. Meanwhile, the implementation time for aluminum formwork is 15 days faster than semi-system formwork.

Abstract

Time and cost control is a very important aspect of project management. Poor time control causes the project construction costs to differ from the planned costs. PT Waskita Beton Precast as the main contractor that carries out the construction of the on and off ramp Jatiwaringin arterial and bridge access projects has problems in controlling time and costs which can be seen in minus deviations in the work progress report. The research method with a quantitative descriptive approach is very supportive in making research by reviewing project performance with the earned value method. The data are processed and analyzed using Earned Value indicators so as to produce a performance index. The results of the study were seen from the deviation of the project progress of 31.57% so that a calculation analysis was carried out in terms of time. With the results obtained to complete the project it takes an additional 85 days from the end of the project contract. Based on the results of the cost calculation analysis. The total cost needed to complete all the work (EAC) is Rp. 48,402,991,553.33.
