We use BIM to create models and designs for our systems and VDC to set up our work processes and scheduling for fast, efficient system builds.

Step Up Your Process

QuesTec has trained field craftsmen to staff our VDC department so our 3D modeling leads to prefabrications that increase the quality and speed of the work on the actual job sites. With this method, we have building components ready to install when we’re given the go ahead to proceed with work, which speeds up the rough-in portion of the job and shortens the time of the on-site install.
