Sicincin–Lubuk Alung–Padang is part of the Trans-Sumatera Toll Road, with a total length of 36.6 km, linking Padang City to Padang Pariaman District. The linkage is expected to boost regional economic growth through the enhancement of transportation services for goods and services as well as tourism between the two areas. PT Hutama Karya (Persero) has managed the planning, construction, operation, and maintenance of this national strategic project since the beginning. Now, this asset represents enormous, estimated investment costs, demanding effective and efficient asset management as a valuable facility for Hutama Karya and the Indonesian Government. Nevertheless, asset documentation is one aspect found to be among the more complex processes because of its level of complexity, value, regulations, environmental changes, and availability impacts on the scheduling impacts for optimization and success in asset management. This study applies 3D Laser Scanning technology in fast-tracking the procedure for creating the As Built Model with BIM to improve the documentation process from implementation up to completed construction. Testing against traditional terrestrial survey methods of level and total station instruments shows that such immersive technology significantly speeds up data collection and model production, enhancing accuracy in volume calculations and optimizing reallocation of field personnel. Such a method is likely to support sustainable construction practices; this would be highly beneficial to the Trans Sumatra Toll Road project for use in the asset management recording process for future project development over the next 10 to 20 years.
