Abstract

AbstractThe use of Building Information Modeling (BIM) is an alternative solution to optimize the time for each step of work in a project. This study aims to determine the duration of scheduling with the normal and overtime method accompanied by the addition of heavy equipment and to determine the stages of planning with the application of 4-Dimensional BIM. The analytical method used is the implementation of a 4D Scheduling Simulation in Building 6th of the State University Education Hospital (RSPTN), University of Lampung. The calculation result by using the scenario of labor use with a normal duration of 8 hours/day showed that the completion of the work takes 272 days. After crashing with the addition of working hours (overtime) for 3 hours and the addition of heavy equipment, the duration was reduced to 200 days with a difference of 72 days. Based on this research, it can be concluded that the use of crashing method increases time efficiency by 36% higher than duration planning using the normal method and the application of BIM 4D can provide solutions that can be used as a reference in understanding engineering and construction plans.Keywords: Building Information Modeling (BIM), 4D Scheduling Simulation, Building 6th RSPTNAbstrakPenggunaan Building Information Modeling (BIM) merupakan solusi alternatif untuk pengoptimalan penggunaan waktu tiap tahap pekerjaan dalam suatu proyek.

Abstract

The building envelope, which serves as the boundary layer between the interior and exterior, plays a crucial role in regulating heat exchange. The shape of the building also impacts heat distribution and airflow within and around the structure. The orientation of the building, particularly in relation to the sun, determines how much solar radiation it receives, directly affecting the building's thermal load.Using Sefaira, a building performance simulation software, researchers can visualize and optimize these thermal aspects. This simulation allows them to experiment with various scenarios related to the building envelope, shape, and orientation to achieve ideal thermal conditions, which are not only comfortable for occupants but also energy-efficient.The findings of this research are expected to provide new insights into sustainable architectural design, especially in tropical regions like Lampung. By understanding and applying the correct thermal principles, buildings can be designed to minimize energy usage for cooling or heating, supporting efforts to reduce the impacts of climate change
