Perencanaan Ulang Berbasis BIM 5D pada Struktur Gedung Rumah Susun Pemerintah Kota Surakarta dengan Dual System

Abstract

The construction sector is one of the largest contributors to Indonesia’s economic growth and requires continuous innovation to enhance efficiency, quality, and competitiveness. Building Information Modeling (BIM) provides a digital representation of building information, enabling more effective planning, execution, and project management. The redesign using a Dual System that integrates a Special Moment Resisting Frame and Shear Wall System, in compliance with  SNI 1726:2019. The process involved preliminary design and structural analysis using SAP2000, 3D modeling and quantity take-off with Autodesk Revit, project scheduling with Microsoft Project, cost estimation (RAB), and BIM 5D integration through Autodesk Navisworks. The redesign resulted in 12 beam types, 3 column types, 2 floor slab types (100 mm and 120 mm thickness), and shear walls with 300 mm thickness. The project achieved a cost estimation of IDR 18,520,710,000 and a construction schedule of 35 weeks. The application of BIM and a Dual System structural approach provides a more efficient and cost-effective planning process. This integration improves accuracy in cost estimation and scheduling while supporting innovation and competitiveness within the Indonesian construction sector.
