Exploring the Potential of BIM-Based QTO for Hospital Structural Work to Support SDGs through Sustainable Construction

Abstract

Quantity Take-Off (QTO) is a critical stage in the planning and execution of construction projects, particularly in ensuring the accurate and efficient calculation of material requirements. QTO methods can be performed using conventional approaches or through Building Information Modeling (BIM)-based systems. The use of BIM in the QTO process has proven to enhance time efficiency, improve the accuracy of material volume calculations, and facilitate data validation and revisions. Case studies on hospital construction projects in Semarang, Samarinda, and Boyolali demonstrate that BIM can reduce calculation errors to as little as 1–2% and decrease structural costs by up to 9.25%. This is particularly crucial for hospital projects that require high precision in structural planning. Moreover, the application of green construction principles and environmental impact assessments using the Life Cycle Assessment (LCA) method represent strategic approaches to support sustainable development. Despite its advantages, BIM implementation still faces significant challenges, including high software licensing costs, a lack of skilled professionals, and limited government support. These barriers are commonly found in regions such as Bali, Jambi, and various areas in Malaysia. Therefore, to maximize the potential of BIM in enhancing efficiency and sustainability in construction projects, a synergy is needed between human resource development, government policy, and the standardization of BIM practices in the field.
