Baystate Medical Center
• 638,000 SF clinical facility in Springfield, Massachusetts
• New cardiac and vascular center with inpatient beds
• Project is predominantly new construction with tie-ins to existing buildings.
Baystate Medical Center
• 55% complete
• Completion date: October 1, 2011
Project Timeline
2005: Master Plan design started by SBA
2006: Owner/Architect meet and decide not to draw
in 3D because of the lack of robust MEP programs
2007: DON Submitted/Berry is onboard
2008: Start of construction - ongoing
2009: March 2009 model startedNovember 2009 model completed
• Revisited 3D drawing concept and advantages of BIM
• Timing and scale of project was the perfect opportunity to start 3D

BIM Benefits
Avoiding the Mad Rush
Owner’s Viewpoint
• Coordination Phase – Concurrent coordination by trades instead of sequential– Estimated time savings of 2-3 months in coordination
• Clash Detection – Sped process to identify, communicate and resolve conflicts– Multiple trades coordinate simultaneously while checking conflicts between each other– CM’s engineer stronger role in coordination between trades
• Early installation – Expedited hanger and core installation using GPS systems along with BIM
• Increased off-site fabrication– Pre-fabrication mechanical risers, PRV stations, HVAC and Plumbing mains, HW and
Steam piping configurations
• Allowed “no-fly” zones for coordination to maintain space for:– Access points for maintenance– Equipment requirements in development, such as unistrut for booms and lifts
Items We Are Working On
• BIM Integration with Operations & Maintenance programs– Space management database– Preventative Maintenance program– Life Safety survey for JCAHO
• O&M Manual incorporated into BIM– Live as-builts incorporating submittals and as-builts into model as we go
• Inclusion of site photos into BIM before closing walls– Provides in-wall details for future renovations & fit-outs
• Standard Specification for future projects
• Model ready for design process on next phases of fit-out– Facilitate communication between designers and CM team in pre-construction
• Estimating, Options development and Scheduling– Increase sped, accuracy for cost estimates and take-offs– Quantify and model potential options and changes more accurately and quickly– Scheduling using BIM
Lessons Learned
• Software – Compatibility – Conversion and input of files between software used by design, CM and Owner– Which software will become industry standard?
• Major Fixed Clinical Equipment – Import of BIM model of major fixed clinical equipment would expedite
coordination between equipment, structure and MEPs– Generally this information is not currently available
• Knowledge – Varied level of use by design professionals and sub-contractors
• Engaged Participants – We have had several brainstorming sessions on the capabilities and goals -
people are engaged and willing to try ideas
Taking advantage of 6D
Proposed 6D Solution
1. Revit Model that includes the following:
Architecturals that include all revisions
Structurals that include all revisions
MEP drawings that include all revisions
Curtainwall system including all u-values used for energy analysis
Room, door and finish schedules
2. Navisworks 3D Model
All major equipment tagged with the following data:
a) Submittals
b) O&M Manuals
c) Commissioning sheet for each piece of equipment
Proposed 6D Solution
3. Traditional 2D as-built drawings
4. Complete electronic record that includes all project correspondence and communication including the following:
All submittals
All shop drawings
All warranties
All drawings
