The primary technical advantages of BIM during the construction phase stem from the integration of 4D and 5D technologies, alongside standardized change management.
4D Technology
BIM enhances the construction process by extracting information from traditional 2D drawings and representing it through 3D models, which act as comprehensive carriers of information. This information is conveyed via images, tables, and text, enabling clearer and more efficient communication across various stages, disciplines, departments, and teams involved in the project. This approach reduces unnecessary losses caused by information overload or miscommunication, ultimately improving both managerial workflow and the building’s overall efficiency.
Introducing the concept of 4D adds the dimension of time to BIM, transforming static 3D models into dynamic process models through computer simulations. The main goal is to simulate the entire construction sequence in a planned manner to identify potential problems and risks early on. This allows teams to develop solutions and contingency plans ahead of time. Additionally, 4D technology offers a solid foundation for construction organization, schedule management, and provides a rapid communication channel with the project owner.
Traditional construction scheduling requires breaking down drawings into detailed specialty divisions, factoring in space, time, machinery, and then creating a schedule based on these logical relationships. BIM streamlines this by enabling intuitive visualization of component sizes and quantities, rapid identification of machinery placement, and simulation of environmental factors such as the surrounding site and access roads. This wealth of integrated information leads to more detailed and rational construction plans.
Furthermore, BIM facilitates early communication with the owner regarding materials and major equipment supplied by Party A, ensuring adequate funding and material availability throughout the construction process. During construction simulations, it also provides workers with an intuitive understanding of project dynamics, helping to prevent safety issues on site.
5D Technology
The 5D aspect of BIM builds upon 3D models by incorporating both time and cost data. Using the building information model, precise material statistics are generated automatically to calculate quantities, procurement schedules, and preparation progress. This helps minimize material waste during construction.
Upon project completion, the BIM model integrates information about claims and changes made during construction. This comprehensive data enables direct final settlements through BIM, reducing disputes during the payment phase and assisting the construction team in effectively controlling costs.
