Revit-Based QMTO Optimization as an Efficiency Strategy in Sustainable Construction Practices: A Case Study of the P2 Foundation of the Main Building of the KPwBI Office in Indonesia

Abstract

Structural work, particularly foundations, is a vital component in building construction projects that demands high accuracy in calculating material quantities. This research aims to optimize the Quantity Material Take-Off (QMTO) process for the P2 foundation type (1500 × 900 × 800 mm) by comparing conventional 2D drawing-based methods with digital methods using Building Information Modeling (BIM) through Autodesk Revit. The research method applied is Research and Development (R&D), which includes stages of data collection, planning, and 3D model development. The analysis results show that BIM Revit can generate more precise digital models and support automated and verifiable QMTO processes. The concrete volume discrepancy between the conventional and Revit methods is −0.180 m³ (−0.926%), the rebar difference is +2066.040 kg (+229.293%), while the number of pile points remains identical. Technical evaluation proves that Revit is capable of detecting actual geometry and detailed structural configurations comprehensively, resulting in more accurate quantity data. The implementation of Autodesk Revit-based BIM has been proven to improve efficiency, material estimation accuracy, and data reliability in structural foundation planning while also supporting the achievement of the Sustainable Development Goals (SDGs), particularly SDG 9 (industry and infrastructure innovation), SDG 11 (resilient and sustainable construction), and SDG 12 (efficient and responsible material consumption), through automated calculations, error reduction, and transparency of construction material data.
