widening a slab, increasing or decreasing the diameter of beams and columns, or changing their position) as well as adding new elements, the MEP engineer typically adds equipment, while trying to avoid the designed geometry of the load bearing structures.
While the structural specialist must often modify existing parts of the project (e.g. Naturally, the workflows of the two disciplines are not exactly the same. Like structural engineers, MEP experts need only certain parts of the project - those which are relevant to their work. Before handing an ARCHICAD file over to an MEP engineer using MEP-specific software, certain simplifications have to be made to the architectural model.
