Abstract

The quality of project construction is constrained by the triangle model of project management, refers to the boundaries of scope, cost and time. The construction project at Universitas Negeri Medan is one of the projects that is experiencing delays and does not meet one of the limitations of triple constraints that must be met by each project. This study has aims to identify the acceleration of project duration using the Time Cost Trade Off method with alternative additions of working hours (overtime) 1 hour, 2 hours, and 3 hours as well as the addition of the number of workers by 10%, 15%, 20%, and 25% from the beginning. From the results of the analysis using this method, it was concluded that the addition of the number of workers as much as 10% from the original is more profitable, where the optimum time of acceleration of the project duration is for 171 calendar days and the optimum cost resulting from the acceleration of the project duration is Rp. 14,059,057,900.00.

Abstract

Nowadays, the development of technological advances and information has grown rapidly in various aspects including the development of construction projects. One of the construction technology innovations is Building Information Modeling (BIM). Obstacles that are often or commonly encountered in the implementation of construction projects are delays or delays in work, rework, and inaccuracies in the calculation of the required quantity. The problems caused by conventional methods can be minimized by utilizing construction technology, namely BIM at the construction stage. This research aims to compare the volume of traditional (conventional methods) and BIM methods. This research uses a comparative research method and quantitative approach. In this research, a comparative analysis between conventional methods and BIM methods is carried out. Based on the data analysis that has been carried out, it is found that the BIM results are smaller than the conventional project results with a percentage comparison difference of 8.61% for the volume of concrete work, and 6% for the weight of reinforcement.
