With $43 million on the line, Amr Raafat, Windover’s Chief Innovation Officer, couldn’t afford to miss his target by even a single centimeter. In play was the setting of modular boxes at Beverly Crossing’s Canvas development, a 126-unit, two-building, mixed-use property in Beverly, Massachusetts. Our Chief of Innovation was to ensure the boxes’ electrical and mechanical chases, where wiring and pipes from the foundation connect to the units, fit perfectly atop the concrete and steel podium that served as Canvas’ base. But as anyone who’s ever worked on a construction site knows, completed buildings rarely adhere exactly to their original plans. Indeed, due to changes in the field, the details of “as-built” structures can vary by several inches from their initial designs.
