Modulus Consulting a San Francisco, CA based firm specializing in, you guessed it, BIM building information modeling is offering the BIM Kiosk that allows on the job construction personnel access to a large 40 inch+ monitor.
Now imagine a live feed from a laser scanner that allows comparison of the 3D design model with the as-found point cloud and highlights potential conflicts.
