When I first started my company at one of our presentations after explaining we could capture as-builts in 3D, then ADT, now Revit, one of the architects in the room stood up and emphatically said, “we don’t want ANY Z-axis information.” To which I replied, “not a problem we can flatten all the drawings.” But that response still resonates with me, how could anyone not want Z- axis information, how come you would want me to strip all the meta data of an object to just a block, to which I have found out, you do not mess with the workflow of an architect’s office so it is of little surprise that construction mangers seem to be the current biggest adopters of BIM and Revit as they are ultimately on the hook for cost management. With that said you have construction managers around the country opening up virtual construction offices to figure out the design, reduce collisions, schedule sub-contracts, etc. before a shovel is ever put in the ground. This is a big change in the zeitgeist since before everyone looked at soft costs, (i.e. engineering and design) as some fuzzy math and did not appreciate it as much as pouring concrete or erecting steel, as that was at least the physical embodiment of the money developers put up. Getting digital files that could fit on a thumb drive just did not seem big enough. Virtual construction has proven itself to pay for itself may times over through quicker build time, less collisions, better decision making, etc and BIM is enabling it. Viva la Z Axis.
