We decided to develop a CMOS camera for advanced construction. After Qatar project, I thought it is not enough to use only digital 3D model in Construction phase. In short, when we work on site, we use 2D shop drawing for construction, but that 2D information could not represent exact real 3D building. This limitation makes us draw more. Many drawing can cause human mistakes.
If we can see the 3d BIM model when we are at the site, or if we can find a point in the floor with out total-station, we can build without 2D drawings.
