Large-scale construction projects involve numerous parties, especially during the construction phase. Contractors must develop a comprehensive plan that details when and where each team enters the construction process to ensure the project stays on schedule. Mistakes are common during construction, but the use of portable computers for on-site guidance can help reduce errors. Utilizing BIM technology, 3D models leverage powerful computer data processing to manage information efficiently throughout the construction phase, improving overall management effectiveness.
After construction, comparing the completed work to the BIM model helps identify any issues. On many construction sites, multiple tower cranes operate simultaneously, often leading to collisions due to poor layout planning. By integrating the tower crane’s slewing radius into the BIM model, a safe distance between the crane arms and surrounding structures can be maintained. This also allows for precise scheduling of crane usage to optimize construction efficiency. In the BIM model, the slewing radius is visually represented by color-coded blocks, illustrating the area affected by the crane’s movement. Collision detection software then generates safety analysis reports for all activities within the crane’s operating radius, ensuring safe operations.
Effective planning of the construction site is crucial. Beyond the building components displayed in the BIM model, the site contains temporary structures, machinery, material stockpiles, and more. Proper allocation of these resources before construction begins is essential. Using 3D BIM models, construction sites can be planned scientifically in three dimensions, covering the layout of worker accommodations, material processing areas, warehouses, storage zones, access roads, and vehicle routes. This approach provides a clear, intuitive overview of the site, minimizes land usage, ensures smooth traffic flow, facilitates personnel management, and helps prevent accidents.
By simulating the construction process beforehand, issues can be identified and resolved early, making project planning more efficient. Cost data can also be integrated into BIM construction management software, enabling real-time tracking of expenses by location and time. This supports material planning and allocation for construction teams.
During construction, simulation technology analyzes the mechanical behavior and deformation of building structures over time to ensure safety. While large-scale finite element software is often used for structural analysis, creating detailed models can be time-consuming. To streamline this, BIM models are exported into finite element software. Since BIM models already include essential data such as material properties, boundary conditions, and load factors, they can be combined with time-dependent structural analysis methods to assess safety throughout construction. This allows for early detection of potential problems, guidance on safety measures, and a significant reduction in accidents.
