Study of scheduling DPRD building of North Lombok Regency using BIM 5D with Tekla Structural software

The Lombok Utara Regency DPRD Building Construction Project is a multi-story building construction project using conventional scheduling methods with an S-curve. In accordance with Government Regulation No. 16 of 2021 on the implementation regulations of Law No. 28 of 2002 on building construction, which mandates the use of BIM for medium and high-rise buildings. This study aims to investigate the use of BIM through Tekla Structures software in planning project scheduling based on Detailed Engineering Design (DED) data. The research methodology begins with the collection of relevant references and shop drawing data. Using the obtained data, a 3D model can be created using Tekla Structures 2025 software, followed by scheduling tasks using Tekla Task Manager. The advantages of scheduling using Tekla Structures include the ability to create detailed models and facilitate scheduling through its available features, which display visualizations of each stage of progress. Compared to conventional scheduling using an S-curve, Tekla Structures provides accurate information through the visualizations it displays. The scheduling results for the construction project of the Lombok Utara Regency DPRD Building using the S-curve required 139 calendar days, while using Tekla Structures software required 111 calendar days. This study demonstrates that BIM technology can significantly enhance construction project efficiency.
