Improvement estimating of project cost and design for a hospital project by using (3D&5D) simulation

Building Information Modeling (BIM) is an approach of managing and generating building data during itslife cycle, dimensional (2D) drawings and later developed to (3D). The scope of BIM 3D, 4D, 5D, in thisresearch 3D model to understand the process project special for beginner's engineers and give idea about allsteps 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 thecapability to create takeoffs the materials, measurements and counts immediately from a model. BuildingInformation models are also more and more used by Owners, Designers, Contractors and Engineer duringthe project lifecycle.Planning and cost estimation used in design phases for huge project to detect errors before start in thework , through account the time required to set up a hospital and reduce the time needed to build the projectthrough overlapping relationships and getting shorter period to build the project utilizing MS Projectsoftware 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 costestimating, the removal of manual takeoffs saves cost ,time and minimize potential for human error.
