As-Built drawings are submitted by a contractor upon completion of a project or a particular job.
They reflect all changes made in the specifications and working drawings during the construction process, and show the exact dimensions, geometry, and location of all elements of the work completed under the contract. Also called record drawings or just As-Built.
By scanning a project before, during and after the work has been carried out, it is possible to compare the different stages, check for clash detection and highlight any discrepancies easily. Thus allowing easy visualisation for both the contractors, architects, project managers and clients, in a timely and cost effective fashion.
