Currently, BIM is widely used during the construction phase, but certain challenges remain—such as limited communication between BIM design and BIM construction information. According to the BIM Architecture Training Network, the future direction of BIM applications in construction will focus on enhancing this integration. Here, we explore key areas for BIM development in construction.
1) Process Quantity Calculation
At present, quantity calculations mainly occur during the bidding and project completion settlement stages. Process quantity calculation, however, involves integrating cost information into a building’s 3D information model throughout construction, forming a Building Cost Information Model (BCIM). This integrated model allows real-time visibility into project progress, resources, funding, and costs. Adjustments in technology or solutions enable dynamic management of the project execution process.
Implementing time-based, segmented calculations of quantities and labor/machinery data using BIM models during construction can significantly improve procurement planning and schedule control.
2) Off-Site Fabrication of Steel Bars and Other Components
Currently, materials such as steel bars are processed on-site, which is inefficient and consumes valuable construction space. Connecting BIM model data with automated steel bar processing equipment can enable digital fabrication, effectively addressing these issues. Studies show that automation increases processing efficiency by tens of times compared to traditional manual methods on site.
This approach can also be extended to other specialties, including plumbing, electrical equipment, steel structures, and curtain walls.
3) Construction Site Network and Mobile Device Applications
Establishing a construction site server combined with mobile devices like iPads and iPhones can significantly enhance site management. This approach allows project information to be uploaded to the internet, enabling seamless management of BIM data and on-demand access to 3D models, attributes, quantities, and more—without requiring software installation.
Moreover, tablets and smartphones offer portability, easy search capabilities, and long battery life, positioning them to replace traditional paper construction drawings on site. This development moves the industry toward paperless offices and electronic on-site information disclosure.
In summary, the future of BIM application during construction will primarily focus on these three areas. Additionally, greater integration of BIM technology with the Internet of Things (IoT) and cloud computing will attract increased attention in the construction stage.
