Abstract

Construction activities inherently carry risks that can lead to accidents, causing delays, injuries, and financial losses. In high-risk projects such as High Voltage Direct Current (HVDC) transmission tower construction, inadequate safety practices and low awareness of Occupational Health and Safety (OHS) increase the potential for workplace accidents. This qualitative descriptive study analyzes potential work hazards in HVDC tower construction using secondary data and the Job Safety Analysis (JSA) method. Four main work processes—tower leg, body, and cross arm installation, and cable pulling—were assessed. Results show that all activities involve significant risks, with falls from height, falling objects, and puncture/scratch injuries being the most common. There are 6 activities in the Extreme category, 3 activities in the High category, 14 activities in the Moderate category, and 8 activities in the Low category. The main risks are falling from heights, being struck by materials, and injuries caused by work tools, which are exacerbated by low use of PPE, weak supervision, and lack of worker compliance. The solution to this problem lies in control priority, where there are four solutions: elimination, engineering, administration, and personal protective equipment control.

Abstract

integration between scheduling (4D) and cost estimation (5D). The literature search focused on peer-reviewed articles and supporting academic sources published between 2019 and 2025, yielding a set of relevant studies. The analyzed data include project types, software used (Revit, Navisworks/Synchro, CostX), data exchange formats (IFC/CSV), and the relationship among the Work Breakdown Structure (WBS), Quantity Take-Off (QTO), and cost account code (COA). The synthesis shows that 5D BIM improves cost accuracy through model-linked QTO, accelerates estimation workflows, and shortens the time required to identify the impacts of design changes on both cost and schedule. The main obstacles to 5D BIM adoption include the loss of information attributes during cross-software data exchanges, inconsistencies in WBS/COA standards across project stakeholders, and limitations in user competency. Supporting factors for effective implementation include an open BIM approach, a Common Data Environment (CDE), standardized cost libraries, and structured training governance. The study also highlights replicable practices such as early WBS alignment for 4D–5D synchronization, rule-based QTO validation, and linking work progress to payment mechanisms. These findings are expected to contribute to the development of 5D BIM guidelines and educational curricula, particularly for small- to medium-scale contractors.
