2 Introduction Presenter Steve Hunt / Dee Cramer, Inc. / Holly, MI BIM Manager & Estimating Manager Sheet Metal Pre-Apprentice Sheet Metal Apprentice Sheet Metal Journeyman 1994 Sheet Metal Draftsman Sheet Metal CAD Detailer CAD Manager / Sheet Metal Estimator BIM Manager Instructor SMACNA Chapter Education Program Certified AGC BIM Education Instructor CM-BIM Certified

3 Dee Cramer, Inc. Company Overview In Business since 1937 Ranked 4 th largest Sheet Metal Sub in US by ENR Magazine 2011 Over $44M in HVAC Work annually Started Drawing in 3D CAD in 1997 Downloading to Manufacturing since 1999 Over 50 BIM Jobs since 2006 for Owners like: - General Motors - Sparrow Hospital - University of Michigan - Owosso Memorial Hospital - Michigan State University - Firekeepers Casino - Saginaw Valley State University - Accident Fund Company - Wayne State University - Lansing BWL Chiller Plant

4 Dee Cramer 6 Years of Success Over $100M of HVAC BIM Related Projects Completed Accident Insurance Fund National Headquarters Lansing BWL Chiller Plant Owosso Memorial Cancer Center WSU Engineering Building

5 Dee Cramer - Benefits Marketing Pursuits 3D MEP Coordination Reduce Potential Installation Conflicts Manage Risk 4D Scheduling Simulate Installation Sequence Great Communication Tool for Field 5D Cost Estimating Interface with Estimating Software Productivity Tracking Detailing Labor Shop Labor Field Labor MEP Coordination - Planned MEP Coordination - Installed

6 Dee Cramer - Benefits Download Duct Direct to Fabrication Equipment * Automated download No punch in * Eliminates human error in punch in BIM allows us to utilize JIT Just In Time Practices * Less Duct Storage on Site Less Clutter, Safer Site * Eliminates Waste of Material Handling * Eliminates Lost Pieces which require rework

7 Dee Cramer - Benefits Fully coordinated HVAC model with steel and other MEP systems Direct interface from fully coordinated 3D model to cutting table Installation drawings from 3D Model. JIT delivery & installation without field changes Potential to reduce raw material by up to 20% Offsite fabrication in shop

8 Dee Cramer - Benefits The Job Fits The First Time Eliminates the need to field measure pieces due to collisions No Interferences = No Interruptions No Interruptions to work flow means higher productivity in the field Conflicts are resolved with less wasted time check the model little or no GC involvement

9 Dee Cramer - Benefits Eliminates Guesswork on Actual Productivity Subs Risk is in Field Labor If you eliminate uncertainties which negatively impact our productivity there is less risk Less Risk = Lower Cost Hospital in Lansing Increased productivity 18% in our bid due to BIM

10 Dee Cramer - Benefits BIM makes Scheduling and Coordination Easier Phase the 3D Modeling with the GC s schedule for Construction Completed Model is like a puzzle it s clear what needs to be installed first Smoother Jobs = Faster Schedule Eliminates unnecessary Change Orders due to interferences No Need to redo as-builts based on actual installation

11 Dee Cramer - Benefits Less wasted materials and rework Recap - BIM Allows for: Less Interferences/interruptions to work flow which allows everyone to be more productive Less Risk = Lower Cost Fewer/No Change Orders Better Trade Coordination and Sequencing Less Congestion of Trades Safer Job Less clutter, fewer lifts, less congestion

12 Dee Cramer - Benefits Productivity Tracking

15 Dee Cramer - Benefits Project Overview 10 Story Hospital New Construction Phased at 2 Story Intervals Design - Bid - Build Delivery Each Phase 100% Complete prior to next phase bid date Phases almost Identical Low Bid Wins

16 Dee Cramer - Benefits Sample Project Payback Phase I 5% higher Phase II Phase II 13% higher Phase III Phase I Phase III *18% more productive due to BIM

17 Dee Cramer The Past Conventional Process Design Bid - Build Sheet Metal Process Procure Plans Electronically or in 2D (Draw #1) Hand Takeoff or On-Screen Takeoff with Estimating Software (Draw #2) No Transferrable data to CAD Department Detail the project in BIM Compliant Software (Draw #3) Design Draw #1 Bid Draw #2 Build Draw #3

18 Dee Cramer The Future is Here Conventional Process Design Bid - Build Sheet Metal Process When provided the Design Model Procure Plans & Design Model Import Design Model Data into Estimating Software CAD Department receives intelligent Design Model Edit Design Model for MEP Coordination & Manufacturing Design Data Creation Bid Leverage Design Data #1 Build Leverage Design Data #2

19 Dee Cramer The Future is Here How does Technology help our Process? Case Study Based on 2,900 Lineal Feet of Duct & 1,300 pieces Estimating On-Screen Takeoff vs. Import Design Data On-Screen Takeoff 8 Hours Import Design Data 4 Hours Accuracy Quantities Automatically build Productivity Tracking Automatically build Project in Accounting Software Eliminate Duplication of Effort Eliminate Interpretation of Information Errors

20 Dee Cramer The Future is Here How does Technology help our Process? Case Study Based on 2,900 Lineal Feet of Duct & 1,300 pieces Detailing / Modeling Detail in BIM Software vs. Edit Design Model Detail in BIM Software 75 Hours Edit Design Model 39 1/2 Hours Ready for MEP Coordination in days instead of weeks Model Potentially contains Manufacturer content for FM Compare Estimate vs. Actual after MEP Coordination Total Pieces, Pounds & Lineal Footage Percentage of Coil Line Duct to Fittings Identify potential cost impacts to Shop & Field Labor earlier

21 Dee Cramer The Future is Here Total Station/Trimble

22 Dee Cramer The Future is Here Actual Hanger Layout for Duct

23 Dee Cramer The Future is Here 3D Scan to BIM

24 Dee Cramer The Future is Here

25 Dee Cramer The Future is Here IPD Success Story Hurley Hospital, Flint MI City Owned Hospital had $30M budget Needs new 50,000 S.F. Emergency Dept Renovation of Existing or Addition acceptable No agenda, style or approach provided

26 Dee Cramer The Future is Here Field Time 4 Days (field time) 234 scan positions 10 Billion Points Project Highlights 1. Decisive factor in winning the project contract for the contractor because of due diligence in preparing for the presentation. 2. Visualize the new ED from several different angles. 3. Completed 3D survey of the campus. 4. Completed the 3D survey without disrupting operations.
