This service includes the creation of detailed discipline models for the entire building services systems (MEP / HVAC, plumbing, electrical, and control systems) in accordance with project requirements and open standards (IFC). The models not only contain accurate 3D geometry, but are also enriched with important technical information such as material, manufacturer, or performance data. The implementation process ensures that the models are structured and coordinated. The key benefit is the early detection of clashes between trades as well as with architecture and structural engineering. The precise models serve as a basis for calculations and simulations (e.g., pressure loss, energy demand), prefabrication, and later facility management.
