The architectural and statistical drawings or the installation schemes of electricity and plumbing which are developed in the Project Phase are also databases for that Project. These schemes and drawings are the inputs for the technical applications and define the construction details, the measurements and the lieu lists. Presently in the technology era, there is the possibility to define and plot those drawings, which were previously drawn manually, three dimensionally in a computer environment with the assistance of other databases. For example, door, window, decoration objects or any other technical drawings are taken from the software object library. Certain software enable us to visualize our project three dimensionally, to report or export the Quantity Surveying or the Lieu Analysis in a desired format.
