Abstract

Concrete volume calculation is a crucial factor in preventing cost overruns when preparing the Budget Plan (RAB) for construction projects. In arch bridge projects, the complex structural geometry often makes conventional volume calculation methods complicated and prone to errors, particularly due to the geometric complexity of the arch beams. This study aims to analyze the comparison of concrete volume calculation results between the conventional method and the Building Information Modeling (BIM) method using Autodesk Revit in terms of cost-effectiveness. The case study was conducted on the Short Span II Pulau Balang Bridge Duplication Project in the Nusantara Capital City (IKN), Penajam Paser Utara Regency, East Kalimantan. The research objects include substructures (bore piles, pile caps, abutments, piers, and wing walls) and superstructures in the form of arch beams. The research method employs a quantitative approach by calculating concrete volumes conventionally using AutoCAD and Microsoft Excel, as well as calculating with BIM Autodesk Revit through three-dimensional modeling and Quantity Take-Off (QTO) exports. The results indicate that the BIM Autodesk Revit method generates a larger concrete volume compared to the conventional method, resulting in a higher total cost based on the BIM volume. The total cost for the conventional method amounted to IDR 142,613,245,996.12, while the BIM Autodesk Revit method amounted to IDR 143,127,208,186.60. These differences are influenced by the level of calculation detail, the simplification of shapes in the conventional method, and the precision of modeling in Autodesk Revit.

Abstract

The construction sector carries a high risk of occupational accidents, making implementation of the Construction Safety Management System (SMKK) essential for construction safety. In Kubu Raya Regency, the West Kalimantan Manpower Office recorded 17 accident cases in 2024 and 13 in 2025. This study analyzes the level of SMKK implementation based on Ministerial Regulation No. 10 of 2021, and identifies supporting and underperforming aspects across four construction projects in Kubu Raya Regency. A descriptive quantitative method was used through structured interviews based on 80 indicators covering five SMKK elements, namely Leadership and Worker Participation, Planning, Support, Operations, and Construction Safety Performance Evaluation, along with field observations. The four projects were selected solely based on their location, regardless of funding source, ownership, or contracting agency. Data were analyzed using the achievement percentage of each SMKK element and the weighted mean method. Results showed SMKK implementation levels of 100%, 98.75%, 78.75%, and 72.08%, with an overall weighted mean of 90,05%, classified as Well Implemented. Projects with lower implementation levels required improvement, particularly in Leadership and Worker Participation, Operations, and Performance Evaluation. These findings indicate that consistent implementation of all SMKK elements plays an important role in supporting construction safety..
