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

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.

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?

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

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.

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

Advantages Disadvantages
Early clash detection for MEP trades High initial cost and training
Better, simpler visualization of ideas One model or several models, and if several, can they work together?
Increase quality of work through entire team having better knowledge of the project
Contractual obligations unclear; who provides the model?
Compatibility of Technologies Compatibility of Technologies
When done correctly, BIM can elicit a higher quality building faster and at a lower cost
Ownership of BIM model after project completion; to the owner, architect, or facility maintenance?
Generational Gap – the experienced team members do not need a 3D model to visualize the 2D drawings, they already think in 3D.
No metrics exist to evaluate success or failure of BIM, nor to assess the cost savings of BIM

Schedule Implications Use of BIM = up front
time to make model Time savings via early
problem ID
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

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

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

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

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

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
The Carl J. & Ruth Shapiro Cardiovascular Center The Carl J. & Ruth Shapiro Cardiovascular Center at Brigham & Women’s Hospitalat Brigham & Women’s Hospital Boston, MA Boston, MA

Faculty Consultant: Dr. Riley
Justification◦ Was there structural
considerations that prompted change in design? Conversation with the
Project Manager and Curtainwall contractor. Change for aesthetics only.
View of existing curtainwall pattern

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.

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

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

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

Sami Boulos Construction Management
Faculty Consultant: Dr. Riley
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
