Building Information Modeling (BIM) is an approach of managing and generating building data during its life cycle, dimensional (2D) drawings and later developed to (3D). The scope of BIM 3D, 4D, 5D, in this research 3D model to understand the process project special for beginner's engineers and give idea about all steps the project. 5D the cost component helps create estimates.
Estimator is consuming 70% of a cost estimator’s time which required to a project. BIM can provide the capability to create takeoffs the materials, measurements and counts immediately from a model. Building Information models are also more and more used by Owners, Designers, Contractors and Engineer during the project lifecycle.
Planning and cost estimation used in design phases for huge project to detect errors before start in the work , through account the time required to set up a hospital and reduce the time needed to build the project through overlapping relationships and getting shorter period to build the project utilizing MS Project software and to detect estimated 5D costing of total construction project, BIM can support cost estimating, the period spent by the estimator on quantification differ by project, using BIM for takeoff or cost estimating, the removal of manual takeoffs saves cost ,time and minimize potential for human error.
