2. BIM > another step change for estimating As the technology continually improves, one thing does not change…. The need for an Estimator!

3. Evolutionary Estimating

4. Why use BIM in estimating? Decision Support & Superior Interaction Improve Efficiency & Reduce Design, Cost & Schedule Risk Make Life Easy for GCs / Subs Win Business + Reduce Risk Make Life Easy for Owners/Designers

5. BIM ties disciplines together: Quality-Schedule-Cost CAD/BIM ENTERPRISE Actual Cost, Quantity & Production data mining Schedule Planning Production Control 4D Cost Planning Cost Control 5D 2D/3D Design Project Accounting Change Mgmt Quantity Takeoff Cost Estimating Project Scheduling Bid Mgmt Cost Control Production Control Constructability Analysis BIM to Field Integration Visual Prez Biz Dev OperationsPreconstruction
