13 Vent Bay Flood Mitigation Design Solutions 14 Fan Plants - ~400 vent bays 8 Stations - ~1,000 vent bays 7 Stations, 1 Plant - ~600 vent bays Vent bay exterior Vent bay interior Mechanical Closure Device (MCD) Deployable Covers 13

14 Arup Approach Innovative Deployable vent covers Mechanical closure devices Flex-Gate TM stairwell protection Polywater FST 250 Manhole insert Flood louvers Market INNOVATION Schedule Users 14

15 Mechanical Closure Device - Design Key design issues: Operating mechanism Fail-Proof Drain Edge Gasket Prototype Contract to Prove Concept: Six Prototypes Positive Lock Unit Maintenance Unit 15

16 Arup Approach Get It Done Notified 9/19/13 that the Governor s office wanted to see the MCD Demo Unit on 10/29/13 to see progress at the time of first Sandy anniversary. The demo unit was fabricated, delivered, and installed to show governor s representative on 10/29/2013. A Grate Fix For Flooding - MTA Tests Hatches That Could Help Sandy-Proof the Subway November 11,

17 MCD Design Development Ventilation analysis to ensure no impact Vent battery inspections for state of good repair Replacement of gratings for standardization and to better meet ADA intent Utility relocations avoided through use of double units and single door units Removable mechanism to facilitate maintenance and inspections Over 1,200 MCDs across all three projects 17

18 BIM-centric Inspection and Design Approach Project Milestones: - Survey, Inspection, Vulnerability Assessment, Flood Mitigation Solution Evaluation, Design, Construction Documents, Construction Phase Support Existing Data - As-builts (early 1900s) - Surveys (formal and informal) Digital Data Inspection Collection - ArcGIS Collector App on ipads Geo-referenced Data Linked to Design Documents 18
