In the current era of development, technology in the field of Architecture, Engineering, and Construction (AEC) continues to advance as a solution to support the rapid growth of construction. Circular of Bina Marga Number: 11/SE/Db/2021 reflects the commitment of the Directorate General of Bina Marga to implement Building Information Modelling (BIM) in the planning, construction, and maintenance processes of roads and bridges. BIM is a method of digitization and project collaboration through an integrated digital model. This research aims to implement the BIM method in the design of an Overpass up to the 5D level using Autodesk Revit and Naviswork software. This effort includes the creation of a 3D model, integration of scheduling data from Microsoft Project, application of clash detection, and comparison of work volumes in the Bill of Quantity (BoQ) report with the Autodesk Revit analysis results.
The research methodology involves modeling structural elements using Autodesk Revit, integrating work schedule data with the Overpass model using Autodesk Naviswork, conducting Clash Detection to check potential clashes between structural elements, and analyzing work volume calculations for subsequent comparison with the BoQ work volume.
The research results indicate that BIM-based scheduling methods accommodate the limitations of conventional methods in terms of visualization and collaboration needs, providing a better understanding of space and coordination among project elements. A clash was found between the leveling mortar bearing pad and the end diaphragm for a 40.8 m girder at each pier. The concrete work volume calculation using the BIM method resulted in 1086.97 m3, with 377.14 m3 for 20 Mpa concrete and 709.83 m3 for 30 Mpa concrete, representing a 1.34% reduction for 20 Mpa concrete and a 1.96% reduction for 30 Mpa concrete compared to the BoQ work volume. The differences are due to Autodesk Revit providing Net Volume work values. Additionally, the calculation of reinforcement steel work volume yielded a result of 97099.85 kg, or 5.6% smaller than the BoQ work volume. This difference is attributed to several factors, including dimensional errors in the Bar Bending Schedule (BBS) that do not match the Detailed Engineering Design (DED) data, incorrect descriptions of the quantity of reinforcement not in line with DED data, errors in the total length of reinforcement not matching the dimensions of the reinforcement, and minor changes in the reinforcement steel modeling process using Autodesk Revit.
