Analysis and Design of Irregular Structure using Building Information Modelling Integration. Case Study: Laboratory Tower

Abstract

In the rapidly evolving Indonesian construction sector, Building Information Modelling (BIM) is gaining substantial momentum, particularly in Indonesia. BIM integration offers comprehensive advantages across the entire building lifecycle. This research centers on applying BIM integration in a 10-story Tower Laboratory at the Department of Civil Engineering, Universitas Indonesia, characterized by structural irregularities. The integration utilizes Autodesk Revit 2023 for BIM modelling and ETABS V21 for structural analysis, employing response spectrum and linear time history methods to assess variations in structural response. The study reveals that response spectrum earthquake loads result in greater responses along the Y-axis, while linear time history earthquake loads lead to increased responses along the X-axis. Spectrum response earthquake loads necessitate an additional 0.64% (21 m³) in cross-sectional area and 1.35% (7805 kgf) more reinforcement compared to linear time history earthquake loads. Additionally, there is a 1.07% cost disparity, amounting to IDR 173,442,791, due to differing analytical methods. This research underscores the potential of BIM in enhancing the construction process, particularly in addressing structural irregularities. The design outcomes and volume calculations from BIM integration can be effectively utilized for life cycle assessments, making it a crucial tool for environmentally conscious and sustainable building practices.
