Virtual Design & Construction

(VDC) is a service that uses virtual design software to create virtual models of buildings. These virtual models are then evaluated before construction starts, allowing project teams to optimize the way a building is constructed by using prefabrication and coordination techniques, saving install hours and not duplicating resources. Using 3D coordination modeling puts modeling data into the hands of the installing workforce.


3D Scanner

Capturing the measurements of a large object or building with conventional documentation methods can take days or weeks, and even then the data might contain errors or missing details. But FARO Focus Laser Scanners create accurate, complete, and photorealistic 3D images of any environment or object in just a few minutes. With their intuitive touch screen and compact design, these FARO Focus 3D scanners are as easy to operate as a digital camera — with built-in protection from dirt, dust, fog, rain, and heat/cold.

  • Improved efficiency
  • Faster, more reliable results
  • Save money by reducing schedule time
  • Pre-construction VDC efforts help identify constructability
  • Improved coordination between trades
  • Create accurate project design with a typical 7 million points per scan and accuracy of up to 2mm
