This project was focused on routing cable trays and modeling the appropriate supporting structures to ensure efficient electrical system installations. We implemented electrical cabinets and designed the corresponding hanging structures for secure mounting. Our team resolved any clashes with other disciplines, such as structural elements and HVAC systems, to ensure coherence in design. Additionally, we modeled 3D families for liquid pumps, based on real dimensions and technical specifications, including related accessories like flow meters, valves, pressure detectors, and liquid level sensors, to be integrated into the main model.
