  1. The Carl J. & Ruth Shapiro Cardiovascular Center at Brigham & Women’s Hospital Boston, MA 3-D Modeling: The Advantages and Disadvantages of a BIM Resource Sami Boulos Construction Management Faculty Consultant: Dr. Riley

  2. Overview • Credits/Acknowledgements • Project Introduction • Depth Topic – Building Information Modeling • Breadth Topics • Acoustical Study • Building Envelope Study • Questions & Answers

  3. Project Introduction Project Team Owner- Partners Healthcare System CM – William A. Berry & Son, Inc. Architect – Cannon Design and Chan Krieger & Associates Structural Engr – McNamara/Salvia Inc.

  5. Organizational Chart

  6. Depth Outline • Overview • Criteria for success • BIM/ 3D modeling Synopsis • External Research • Project details • 3D modeling Advantages • 3D modeling Disadvantages • Conclusion/Recommendation

  7. Overview • Why BIM? • PACE Roundtable – One of 3 major industry issues today • The Future of the industry • Personal Interest • Project Specific • High Profile Project – familiar owner • High Level of MEP Coordination

  8. Overview • BIM today • Used predominantly for 3D coordination, especially with the MEP trades • Only certain members of industry utilize BIM tools, i.e. architects, MEPs, and CMs • Problem Statement • BIM tools growing in the industry today, but opposition still exists, causing the BIM push to stagnate and not reach its full potential.

  9. Criteria for Success • Provide some advantages and disadvantages to the BIM tools in the industry today • Relate BIM to this project • Which tool(s) of BIM used? • Successful/unsuccessful with that tool? • Provide opinions and illustrate research • Come to a conclusion and recommendation • Is it logical?

  10. BIM/3D Model Synopsis • BIM ≠ 3D Modeling • 2 separate concepts, but tools similar • 3D model is an aspect of BIM • BIM model incorporates: • 3D representation of 2D drawing • Cost and schedule data • Materials Information • Future of BIM • GSA: BIM Standard procedures for all new federal projects • Increasing demand from owners • Provides for faster, better quality projects at lower costs

  11. BIM Drawbacks • Industry • Some trades and companies not applying 3D models to projects • New contract models not being written, legal ramifications not addressed • What happens to Design-Bid-Build process? • Experience vs. Inexperience • New workforce members need 3D models to visualize 2D drawings • Veteran members can already “see” in 3D.

  12. Industry Poll • Research of articles and survey of AE Construction Mentors revealed: • BIM becoming more prominent part of projects • Software used for modeling: • Autodesk REVIT and REVIT Structural • AutoCAD 3D, AutoCAD MEP • Innovaya – for Estimating • Microstation • Project Specific • Fully Integrated BIM was not used • 3D Model for MEP coordination • Survey of Berry staff results • Berry incorporating VICO 5D Presenter - MIT

  13. 3D Modeling

  14. Cost, Schedule, Quality • One major component against BIM is Cost • Software/technology • Employee to operate • Exact cost unknown for Berry, but 1-2 employees operate and maintain the models for entire company • Value Added • Applying more efforts with 3D modeling and BIM gives a much better quality project • More knowledge about project, better • Schedule Implications • Use of BIM = up front time to make model • Time savings via early problem ID

  15. Conclusion • BIM and 3D Modeling will lead the construction industry of the future • Efforts by GSA, companies like Berry, PSU AE • Better visualization = better projects • For the Carl J. & Ruth Shapiro Project • 3D modeling only for MEP coordination • Breadth topics to discuss any further 3D endeavors

  16. Recommendation • Industry: continue improvements via BIM • More integration of 3D models: • Sequencing of project phases – • Excavation • Superstructure • Building Envelope • MEP • Finishes • 3D models to accompany coordination drawings • As-Builts in 3D for maintenance staff of building • Project Recommendation • Follows Breadth analyses

  17. Breadth Topics • Analysis 1 – Acoustical Study 10th floor VIP rooms • Existing Conditions/ Success Criteria • Redesign and calculations • Results and conclusion • Recommendation • Analysis 2 – Building Envelope • Existing Conditions and Success Criteria • Redesign and calculations • Results and conclusion • Recommendation

  18. Acoustical Study Picture of Rooftop AHUs and Cooling Towers • 10th Floor – VIP Patient Rooms • Sound sources include Air Handling Units, Cooling Towers, Compressors • Strict rules for sound attenuation in hospitals • Research if acoustical system over-designed for space. • Acoustician = Cavanaugh & Tocci Associates, Inc.

  19. Acoustical Study • Over-designed? • Examined the system as installed • Trane Acoustical Program used to estimate acoustical values for Source dB. • NC>65

  20. Acoustical Study • Conclusion • Acoustical Design ok • Meets required design criteria by owner • Added challenge due to restriction of duct-lined insulation • Recommendation • Use design by Acoustician • BIM Consideration • Research into incorporating TAP as part of BIM

  21. Curtainwall Study • Curtainwall of glass, aluminum • Random pattern aesthetic on exterior of building • Original design: 9 different types of glass and aluminum • Architect Design Change: 43 different types of glass and aluminum • Research: • Reason for the change • Implications on the project • Conclusions

  22. Curtainwall Study View of existing curtainwall pattern • Justification • Was there structural considerations that prompted change in design? • Conversation with the Project Manager and Curtainwall contractor. Change for aesthetics only.

  23. Curtainwall Study • Implications: • Mechanical System Impact • Aesthetic effect made • Cost, Schedule, Value-Added

  24. Mechanical System Effect • Change to design alter % glass to envelope • Increase glass = increase solar gain to space/building • Trane Trace calculation • Simple building envelope calculation to test solar gain effect of design change.

  25. 35% glass 55% glass • Effect of % Glass on Mechanical System • The higher % glass, the more heating or cooling needed in a space = higher cost and more energy consumption

  26. Aesthetic Effect • Desire to make exterior pattern more random • Utilize many tints of glass & Aluminum • Effect not attained after construction of design change

  27. Cost, Schedule, Value • Cost • Approx. $2 Million for 43 glass types • Increased Heating/Cooling costs, energy consumption • Project Schedule not affected • Value added: • In theory yes because of random pattern • In actuality, no distinguishable change

  28. Conclusion • Architect’s change achieved minimal aesthetic improvement • Cost increase, no schedule impact, minimal value added • Recommendation • Return to original design • Cost savings > $2 million • BIM Consideration • A 3D model would have been too precise to illustrate the aesthetic differential. • BIM model to illustrate solar calculations • Not used on this project, but capability exists in industry

  29. Lessons Learned Many issues, many solutions One change affects many components 3D Modeling becoming the norm
