With the increased congestion inside the building, the potential for accidents, conflicts between trades, and reduction in productivity will be highly likely. The usage of BIM on this project has proven to be very successful in coordinating the MEP systems to avoid on-site system clashes; however, BIM does not coordinate the flow of work of different trades, as all crews will be racing to meet their schedule deadlines causing major congestions. The goal of this analysis is to determine the cost and schedule time benefits of prefabricating patient rooms due to the repetition of the design.

During the Design and Development of the Children’s Hospital project, a total of three 3rd party estimators were hired to estimate the costs of the project as the Architects progressed through the design. In addition, to the three 3rd parties involved, each contractor bidding for the project had to develop and estimate the project costs. The Children’s Hospital is a large project with many systems to be estimated and evaluated. The lengthy process of conducting manual hand take-offs on 2D drawings could negatively impact the entire project team during construction. The biggest risk of conducting manual take-offs during construction is when the owner’s team decides to change scope of work or add new bulletins. Manual take-offs can greatly hurt the project schedule and costs if not conducted in a quick and efficient manner. The primary goal of this analysis is to utilize 3D modeling software to conduct material Quantity Take-offs and pricing. Software will be used to analyze the benefits of utilizing 3D Estimating techniques in developing accurate and quick estimates. The analysis will compare 3D software estimating techniques to the traditional commonly used manual estimating methods.
