Unmanned Aerial Vehicle (UAV) equipped with photogrammetry has a significant impact on sustainability. Despite the advances in construction equipment and management techniques to control the complexity and dynamic nature of toll road projects, the documentation of changes which occur on site remains a prevalent issue. This research is concerned in the visualization techniques for progress monitoring that illustrates progress deviations through superimposition of four-dimensional as-planned model on surface models. The results from the digital survey into BIM Authoring Tools followed by the identification of BIM elements through surface modelling. The analysis is conducted using the parameter of the volume of land cuts and fills to quantify deviations. The data retrieved from UAV drones enriched with geospatial parameters proved to provide reliable construction records, allowing greater control of construction progress. The proposed methodology may ultimately allow project participants to adjust schedule and allocate resources in a more precise manner.

Recent innovation of Building Information Modelling (BIM) and its encouraged application in digitalizing design and construction within the architecture, engineering, and construction (AEC) industry are essentially shifting the process by which structures are designed and constructed. For instance, larger infrastructures like dams have been associated with inherent complexity throughout its construction phases. Started with planning phase, continued by construction, and handed over into operation and maintenance phase, scheduling and monitoring progress require highly accurate data for input, process, and output to be coordinated between stakeholders. This study presents a systematic approach in tackling issues related to the integration of construction phases, specifically concerning construction monitoring efforts based on BIM. The analysis conducted was concentrated on integrating scheduling and monitoring into a BIM model of a dam, as this study also discusses the potential added value of BIM implementation on dam projects where the whole engineering process can be improved with digital tools, as well as explain and illustrate the modelling mechanism undertaken. The method exemplified in this study is expected to encourage the implementation of BIM in dam constructions and management to enhance effectiveness and encourage sustainability.
