BIM for FabricationBIM is very useful for the digital fabrication of structural steel. BIM can model entire steelwork structures in 3D along with last notch, plate and bolt to facilitate the fabricators in reviewing a 3D steel structural model right from the fabricated components. All detailed information as well as the drawings, material list and other data are automatically generated from the model. The various data can then be transmitted to production planning and automation systems. Such automated routine tasks permit the fabricator more time to focus on the principle precast design and detailing decisions. A purpose-built building information model can nourish the manufacturing process as the design model contains all the geometry related with structural steel. The design informations are exported to a CIS/2 file (an industry standard data format for replacing steel information) to be used again in a steel detailing application. |
Once the steel detailing is completed, the design team or contractor utilize the fabrication model for 4D modeling and clash detection with other building disciplines and models (MEP, architectural, etc.). The fabrication model contains more detail than the structural model, and consequently helpful for interference checking, particularly for building types or application where space is extremely tight. Applying the design model directly for fabrication will produce a usual feedback loop among fabricators and designers. It will convey fabrication considerations forward into the building design procedure. Sharing the design model with fabricators for bidding will curtail the bid cycle and initiate more consistent bids based on reliable steel tonnages. And the coordination among the fabricated steel and the other building components will decrease the on-site issues and lower the increasing cost of steel erection. An integrated BIM model empower fabricators to manage not only the fabrication phase of the project but also other verticals of the project as well as modeling, fabricated parts design and elaborating, contract management, financial evaluation, and supply chain management, along with keeping track of updated manufacturing data. Trim down project cost by removing any inaccuracies in the design of fabrication components, minimizing wastage and ensuring timely delivery of project.
