In case that you are interested in working with more than one 4M Verticals, you will take profit of the added value, which is coming from the seamless integration among the 4M Verticals. Impressive communication and data exchange flows between all the verticals are due to the fact that the Building Model is unique regardless the specific Vertical. For example, the HVAC designer works directly on the idea model taken from the Architect, the structural engineer returns to the Architect the architectural model enhanced by the structural requirements (for a possible iterative optimization approach) and so on.
