Using 4D BIM Model in Documentation of Construction Projects As Case Study in Iraq

Abstract

The type of works in construction companies and construction projects requires dealing with a large and complex amount of information and documents. The processes of documentation, information exchange, and updating information and data have become one of the administrative challenges facing construction project management. Construction companies and projects in Iraq still deal with paper documents only, which leads to a large number and accumulation of documents, and this leads to an increase in time and effort in searching for the required documents and information. This study aims to use the 4D BIM model in the documentation of projects. The results showed the project schedule is also documented, as the schedule is linked with a 3D model in Naviswork software to create a 4D model that simulates reality. Also, the authors make a comparison of quantities in manual documentation vs BIM for (foundations, columns, beams, slabs, staircase, floors, secondary ceiling, tiles, and stone ) then calculate the percentages of actual quantities and BIM are (1.6%, 1.7%, 2.4%, 0.29%, 4.15%, 0.52%, 0.32%, 2.13%, and 0.23%) respectively and these percentages are small and acceptable. Hence, this paper used external links to open files in Navisworks with many different formats.
