• Orientation to East Side Access program
• Overview of Model and its development
• Examples of Model application
• Some lessons learned
• Key benefits to the CM of BIM tool
Presentation Agenda
• Capacity limitations are choking new transit growth throughout New York City
– LIRR is at capacity
– Penn Station is at capacity
– Penn Station is not located on the east side of Manhattan, where about half of LIRR’s customers ultimately go
East Side Access – why build it?
•Provides 162,000 trips per day
•Saves thousands of East Side-bound commuters 30-40 minutes per day
•Relieves congestion at Penn Station
• Increases East River tunnel capacity
• Improves operational flexibility through Harold Interlocking (Amtrak, LIRR, NJT)
East Side Access – how does it help?
East Side Access – by the numbers…
Project Scope:•$10+ billion cost•71 construction contracts•8 miles of new tunnels•3 miles of existing tunnel•25 miles of track •7 interlockings•11 facility power substations
• 8 traction substations• 69 elevators and
escalators• 2 control centers• 13 fan plants• 18 miles of ductbank• 148 miles of cable
3D Printed Mock-upsVirtual Mock-up
• Project Logistics Support
• Analysis of pre-cast vs. poured
Constructability Review
Capturing existing conditions – GCT concourse level
Laser point cloud Generated model
• Eight City blocks scanned
• Eliminated the need for a construction survey
Linking assets and operational data together
Facility Management
• QR Coding of equipment upon installation
• Coding can be part of inspection protocol
• Linked to Asset Management System
Concourse Level Equipment Tagging
Facilities Management drawings –linked to field
FM sheets of assets /equipment tagged with unique IDs and location
• Modeling standards to ensure integration across contracts
• The BIM management team has to be embedded with the Project team
• The BIM goals have to be clearly defined
Some lessons learned
• Visualization of complex interdisciplinary construction coordination helps identify and resolve issues
• Integration of design, construction schedule and progress records gives management efficiencies and
• Time-stamped accurate field data helps avoid and defend claims
Key benefits with BIM integration
