Abstract

High-rise building projects expose a high risk due to structural design complexity, large workloads, and long project duration. The complexity of the work includes the design of Mechanical, Electrical, Plumbing (MEP), HVAC (Heating, Ventilation and Air Conditioning) systems, early warning, watering systems, hydrants, sprinklers, evacuation routes in the form of emergency stairs and fire doors. This research focuses on the application of BIM 5D to estimate and improve the cost performance of MEP work in high-rise hotel buildings. This research combines qualitative and quantitative approaches through in-depth interviews and BIM 5D modelling to achieve the research objective. The results showed influential factors for BIM implementation namely 2D Drawings, BIM 5D implementation, specification and technical plan, operator experiences, BIM 5D models, individual selection model, estimating, calculation process, cost database, and operator education. The findings of this research also show a cost efficiency of 3.56% from the BIM 5D implementation to the high-rise hotel building.

Abstract

Green retrofitting aims to guide buildings toward sustainable practices, reducing carbon emissions associated with building operations and construction. This study explores the application of Building Information Modeling (BIM) 5D Quantity Take-Off (QTO) to existing high-rise buildings, focusing on components that enhance the performance of environmentally friendly structures and project management. This research identifies the factors influencing the cost estimation process and examines the risks across various phases, activities, outputs, and utilization of BIM 5D in cost estimation. The study highlights the most influential factors in implementing green retrofitting for high-rise buildings using structured interviews, questionnaires, and expert validation. The analysis demonstrates that BIM 5D QTO significantly impacts the risk associated with cost estimation in green retrofitting processes. The study ranks the criteria based on respondent feedback by employing Relative Importance Index (RII) analysis. The statistical analysis identifies key factors affecting the risk of cost estimation in BIM QTO for green retrofitting of high-rise buildings. These factors include evaluating specifications, defining acceptance criteria, decomposing the high-level Work Breakdown Structure (WBS), inputting sizes and specifications of each work component into the 3D model, integrating scheduling into the 3D model, and establishing a BIM Execution Plan.

Abstract

Construction projects are expensive, complex, and difficult to keep on budget. Cost overruns are common. The consequences, including delays, disputes, and financial losses, appear repeatedly across the sector. Enterprise Resource Planning (ERP) systems have been widely adopted to address this challenge, but evidence on how SAP S/4HANA performs in Light Rail Transit (LRT) construction is limited. This study analyzed the critical success factors of SAP S/4HANA implementation and evaluated its effect on cost control performance in an LRT project in Jakarta. Data were collected from two sources: a questionnaire distributed to 50 respondents involved in the project, and cost records extracted from SAP S/4HANA at project completion. All variables were validated through expert consultation before the main questionnaire was distributed. Three factors significantly affected cost control performance. SAP S/4HANA system quality (X1) was significant at sig. = 0.017 (t = 2.466). Organizational support (X2) was significant at sig. = 0.019 (t = 2.347). SAP S/4HANA users (X3) produced the strongest effect, significant at sig. = 0.000 (t = 4.708). The F-test confirmed that all three variables jointly affected cost control (F = 11.834, p < 0.05). User competence ranked first among the three factors, followed by system quality, then organizational support. The project recorded a Cost Planning value of Rp 4,665,465,828,436 against an Actual Cost of Rp 4,656,147,335,236. Earned Value across all four project zones reached Rp 4,915,100,000,000. The Cost Performance Index (CPI) was 1.055, indicating the project was completed within the planned budget. These findings extend ERP success research into transport infrastructure, where empirical evidence of this kind is scarce. Contractors deploying SAP S/4HANA on large construction projects should prioritize user training across the PS, MM, and FI modules before construction begins. On this project, the system provided real-time cost visibility and kept project spending within the planned budget.
