BIM (Building Information Modeling) helps review a construction plan, identifying constructability issues during the pre-construction stage. BIM implementation detects potential roadblocks and design flaws that could result in cost overruns and rework. The evaluation of the entire project process is carried out through BIM before construction. Full project analysis can be performed from conceptual design through construction, identifying issues that may arise due to design incompatibility, space conflict, circulation, logistics, and more. Design revisions and updates can also be tracked during the design development of a project. Additionally, BIM helps improve the site process.
Let’s see how BIM can help solve construction problems for various trades
Electrical Trade – Electrical plans for a large build may not be equally understood and interpreted by all project stakeholders. This leads to rework in construction and wasted time and resources. 3D BIM collaboration is an efficient way to bring all project stakeholders together on the same platform. BIM Constructability Review helps in this regard by acting as a visual tool for managers, field staff, and other stakeholders. Top-level BIM coordination ensures fast, error-free construction, reducing field-generated change orders and rework. In addition, installation interruptions and work stoppages are eliminated. Constructability issues identified by BIM in the electrical trade include adequacy of space for installation, operation and maintenance, optimal use of fixtures, use of bend radius per code, mounting heights per code, clearance between services and location of electrical elements in the right place.
Concrete: BIM helps to find various inconsistencies in input drawings and incomplete information for the concrete trade. Several conflicts are identified that could have affected the actual construction in terms of cost, material and labor. BIM minimizes waste by revising designs, such as changing the pour sequence, modifying the mesh slab thickness, finishing the floor opening, and more.
HVAC Trade-BIM coordination helps identify conflicts and presents them to consultants, resulting in design review. Coordination issues are resolved through drawing validation, such as flue colliding with structure and other trades, FPB colliding with wall and structure and more. The final HVAC model is produced by eliminating conflicts by changing the route and size of the duct, as well as changing the elevation. This helps prefabricate assemblies with a quality configuration, reducing installation time, waste, and cost.
Seek constructability review via BIM and resolve conflicts prior to construction. Buildability review and clash detection analysis are often performed with software such as Autodesk Design Review, Navisworks, and more. Choose a competent BIM service provider to identify construction conflicts and solve them efficiently. BIM visual analysis helps achieve construction safety standards, allowing schedule visualization with the installation of permanent construction parts and temporary safety fixes prior to construction. Implement BIM to match your construction workflow perfectly.
