Abstract: Leveraging the existing capabilities of BIM, and 2D representation, with the addition of metadata (3D + 2D + 1D) one will get a UniModel. What is a UniModel? It is a relatively new word that describes an adherence to a process that accounts for the majority (@99.9%) of project construction costs. Considering that the concepts of total cost management (TCM) involve determining the quantity of work, including costing and pricing; using a combination of a sophisticated library (or database) of cost items with detailed resources (labor, material, equipment, etc.), factored and intelligent assemblies, standardized cost and WBS (work breakdown structure) coding structures; will allow cost professionals to more efficiently provide valuable cost data. Project control at the Central Puget Sound Regional Transit Authority (RTA), aka Sound Transit (ST), which services Pierce, King and Snohomish Counties in Washington State, have successfully employed part of this process with their unit cost library (UCL) used for the ST3 program presented and approved by voters for $53.8B, in year of expenditure dollars (YOE). There remain challenges that have yet to be overcome. However, a proof of concept (POC) has been established and the future of managing project cost looks bright.
