#14 - Construction and Fabrication Benefits of BIM

• Use of Design Model as a Basis for Fabricated Components: If the building model is connected to a BIM fabrication tool and detailed precisely; building objects can be illustrated accurately for fabrication and construction. As the objects are already prepared in 3D, automatic fabrication is done by means of machinery. This allows dealers to elaborate the model more accurately and expand the information required for fabrication so that more precise and effective fabrication can be done. As a result of offsite fabrication, construction cost, and duration decrease.

• Quick Reaction to Design Changes: As a result of parametric modeling, if any changes are made in the building model; it will automatically reflect in other respective objects. Additional updates are done with and updated visually and via clash detection. These changes are automatically reflected in the model and in all perspectives. Due to adjustments that can be shared, visualized, estimated, and resolved without the use of time-consuming paper-based transactions, design modifications can be done more quickly.

• Discovery of Design Errors and Omissions before Construction: Because all drawings are created from the building model; errors caused by inconsistency are eliminated. Moreover, models from all disciplines are compared and integrated together, this kind of design is effectively checked both systematically and visually. As a result, clashes and constructability issues are solved before they can be detected in the field. Ultimately it permits speedier construction, lesser costs, and offers smoother procedures for the entire project team.

• Synchronization of Design and Construction Planning: 4D construction planning requires an integration of the building model and a construction plan, which displays what the site could appear at any given time. This simulation offers extensive insight in day to day construction processes and shows possible issues and risks and provide opportunities for possible upgrade. Such analysis cannot be done through conventional 2D CAD systems.

• Synchronization of Procurement with Design and Construction: Accurate building models provide precise quantities that can be later used for the procurement of materials from vendors and subcontractors.
