When we talk about Building Information Modeling (BIM) we are not talking about a trend, but about a real digital revolution in the building sector, ready to break up obsolete schemes and processes. For a long time, the engineering and construction sectors were looking for tools to increase the productivity and quality of their projects by reducing costs and delivery times. BIM has positioned itself in these sectors as the ideal tool for achieving these goals. Electrical engineers can complete all aspects of electrical design including power and lighting, fire alarm, communications, security systems, and other building services in a single environment. Through BIM, electrical engineers will be able to detect clashes and avoid electrical conflicts due to contradictory information between documents and building systems. elec calc ™ BIM is an essential solution for electrical engineering. It is the first software in the world that perfectly integrates the electrical calculation in the BIM process. With elec calc™ BIM, the user can design, calculate and size the electrical installation in the digital model in IFC 4 format, generated by any 3D architecture software (Revit, ArchiCAD, SketchUp …). For REVIT users, the elec calc™ BIM plug-in optimizes collaboration between the two programs. The compatibility with the electrical objects available on the BIM&CO platform is also an important resource for integrating and calculating the products of the manufacturers. elec calc™ BIM offers unique routing capabilities. The user calculates the lengths of the cables generated in the digital model and it is also possible to perform different simulations to compare different routing scenarios. The 3D model allows for conflict detection and the BIM Collaboration Format (BCF) technology, integrated into the software, allows you to manage all communications and alerts with other operators.
