When a construction project begins, it involves not only lot of planning but it needs lots of surveying. The survey involves many aspects and the engineers have to make multiple visits to the site to understand topography of the site and its adjoining set up & available space layouts like roads, pavements, other structures like electric poles etc. Creating 3D scans of the site and its neighbourhood which takes very little time but provides all the desired details to its minutest measurements and all features to their last details. These 3D scans can be sent to multiple engineers across the world to invite their expert advice with no need for anyone to visit the site. The 3D scanners are capable to scan any excavations, heritage/architectural sites of importance mines, tunnels, railway lines, yards, factories etc. to help conduct survey from a remote locations to the last details.
