First and foremost BIM is the life-cycle management of the built environment supported by digital technology. While the industry is currently fixated upon 3D visualization tools, aka Revit, Archicad, Bentely… they only represent components of a BIM solution.
Construction cost estimating, and facility life-cycle cost estimating are critical components of any facility design, project delivery, repair, renovation, sustainability, or planning function.
Here’s a list of BIM Construction Cost Estimating Requirements:
1. Collaboration – involvement of all stakeholders – Owners, AE’s, Contractors, Oversight Groups, Community …
2. Transparency – Appropriate access to cost information, and associated comparison to published independent third-party costs such as RSMeans Cost Data.
3. Consistent Format and Terminology – Use of a standard set of terms and data architectures such as Uniformat, Masterformat, Omniclass.
4. Metrics and Benchmarks – Time, Accuracy, Cost
5. Proper allowances for local conditions – geographic, weather, productivity of labor, …
6. Appropriate level of technology to assure productivity, collaboration, security, audit trail.
7. Robust Process – The application of a robust process and business “best-practices” with a focus upon continuous improvement.
8. Appropriate knowledge of all “levels” of construction cost estimating and their potential accuracy – Square Foot / Conceptual / Building Level Construction Cost Estimating, Assembly / System Level Construction Cost Estimating, Unit Line Item Construction Cost Estimating.
9. Knowledge of the impact of the Construction Cost Delivery Method upon construction costs and life-cycle costs – Design-Bid-Build, CM@Risk, Design-Build, Job Order Contracting, Integrated Project Delivery
10. Fundamental understanding of Total Cost of Ownership and Facility Life-cycle Management – Physical and functional conditions, Operations, Sustainability, Renovation, Repair, Efficient Project Delivery Methods ( IPD-Integrated Project Delivey, JOC – Job Order Contracting )
