Housing complex development project. Roads, terrain, soil, underground pipeline, manhole, etc. all things 3D modeling of complex configuration was conducted to check the interference between them, to submit a report on the things that interfere, and modifications were re-modeling. This process to advance the construction could prevent errors:

 Review of Construction Design. /Comparing BIM with 2D based design. /Detecting

 the errors of 2D based design. /Quantity Estimation of the Construction materials.

 Extraction of Drawings from BIM’s information model.
