Abstract

Labor is a crucial resource in industrial construction projects. A common issue is the uneven number of laborers who are overallocated. This study uses the resource-leveling method to compare and determine the optimal number of labor and project duration based on plan, real, and regulation conditions. In this study, the data required in real conditions is obtained from daily report data. In planned conditions, data is obtained from the scheduled manpower made by the contractor, while in conditions based on regulations, the calculation of the number of laborers uses the coefficient values listed in the Regulation of the Minister of Public Works and Public Housing No. 1 of 2022. This research is measured through disparity values, which show an imbalance in the allocation of labor caused by the uneven allocation of labor based on its workload. The results showed a significant difference in the number and distribution of labor. Regulation conditions resulted in higher labor numbers due to detailed calculations on each type of work and labor qualifications. The highest disparity occurs in workers, with a value of 0.93 in the plan condition and -0.51 in the regulation condition. The resource leveling helped balance labor allocation but increased project duration from 98 to 112 working days. These findings provide practical insights for project managers to optimize worker planning and distribution, improve efficiency, and reduce overallocated risks.

Abstract

This study analyzes the productivity of tower cranes in high-rise building construction projects in Indonesia, focusing on sustainable practices and advanced techniques. The rapid growth of infrastructure has heightened competition in the construction sector, making efficiency essential. Tower cranes are key to accelerating project timelines and reducing costs, but their productivity can differ between theoretical specifications and actual field conditions. Using a quantitative descriptive method, this study compares theoretical productivity based on equipment specifications with direct field observations of the Potain MCT 205 tower crane at a high-rise site. Data on cycle time and lifting volume for work such as column reinforcement and concrete pouring were collected. Results show that theoretical productivity is higher than field observations, with a 40% increase for works and up to a 92% increase per phase. The findings stress the importance of incorporating advanced planning and sustainable practices to optimize productivity, minimize delays, and reduce costs in construction projects

Abstract

Inadequacies in the conceptualization and assessment of construction scheduling frameworks can disrupt the epistemic continuity of project execution, thereby undermining procedural coherence and operational efficiency. Accurate and detailed material quantity planning is essential to ensure precise resource forecasting and the development of efficient and reliable construction schedules. This research investigates the role of methodological selection in the accuracy and efficiency of construction planning, with a particular emphasis on material quantification and scheduling outcomes through this comparative framework. The methodological approach undertaken in this study involves quantity surveying practices through the application of two modelling-based techniques, namely CAD-Revit and CAD-Conventional. For construction-shop drawing documentation as the primary data source, material quantities derived from each method serve as the basis for schedule development. This process culminates in the integration of 4D Building Information Modelling to facilitate the temporal visualisation of construction sequences, which supports a more comprehensive evaluation of the implications associated with each quantity derivation method on the accuracy of project planning. The comparative analysis of material quantities derived from the two methods revealed significant fluctuations, with the CAD-Revit approach demonstrating greater efficiency in material usage. This variation was further reflected in the scheduling outcomes, where the 4D BIM methodology indicated divergent timelines for the completion of structural component progress across different floors.

Abstract

The development of technology has significantly influenced the construction industry, introducing innovations that enhance project execution efficiency and accuracy. One of the notable advancements is Building Information Modeling (BIM) is a digital representation of a building that fully illustrates its form, size, and functional aspectsThis study aims to implement Building Information Modeling (BIM) for Quantity Take Off (QTO) using Autodesk Revit 2025 and compare its results with conventional methods in terms of volume and cost estimation accuracy. The research object is the South Cross Road Construction Project (JLS) Lot 3 from Pantai Serang to Sumbersih. This comparative quantitative study utilizes Detail Engineering Design (DED) documents and 3D modeling with Autodesk Revit 2025. The findings show that BIM-based QTO produces more accurate and efficient cost estimations, especially in complex calculations such as cut and fill operations. The BIM method resulted in a total project cost that was 13.73% higher than the conventional method, primarily due to more precise terrain modeling. This research is expected to be a reference for improving the accuracy of infrastructure project cost estimation.
