When it comes to applying BIM during the construction phase, what are the key considerations? Many professionals from construction teams can probably list a few. Today, the editor from BIM Building Training Network will discuss several important aspects of BIM use in the construction stage.
1) Process Quantity Calculation
Currently, quantity calculation is mainly performed during the bidding and completion settlement phases. Process quantity calculation involves integrating cost information into the building’s 3D information model during construction, creating a Building Cost Information Model (BCIM). This integrated model combines cost and quantity data, allowing stakeholders to monitor progress, resources, funding, and expenses in real time. It enables dynamic adjustments to project execution through changes in technology and solutions. Achieving time-based, segmented calculations of quantities and labor/equipment data through BIM models during construction can significantly improve procurement planning and schedule management.
2) Off-Site Production of Steel Bars and Other Components
Traditionally, key materials like steel bars are processed on-site, which is inefficient and takes up valuable space on often limited construction sites. By connecting BIM model data directly with automated steel bar processing equipment, the process can be digitized and streamlined. According to statistics, this automated method is tens of times more efficient than manual steel bar processing on-site. This approach can also be extended to other trades such as plumbing, electrical installations, steel structures, and curtain walls.
3) Use of Construction Site Networks and Mobile Devices
Setting up a dedicated construction site server combined with mobile devices like iPads and iPhones can greatly enhance site management. This setup allows various project data to be uploaded to the cloud, enabling effective management of BIM data and access to 3D models, attributes, quantities, and more at any time and from anywhere — without needing to install specialized software. Furthermore, tablets and smartphones can replace traditional paper drawings on site, thanks to their portability, easy search capabilities, and long battery life. This truly moves construction sites toward a paperless, electronic workflow for project information.
Additionally, the integration of BIM technology with the Internet of Things (IoT) and cloud computing during the construction phase is expected to gain increasing attention and adoption.
