LA Metro Regional Connector @ 1st /Central – Little Tokyo/Arts District Station

The Regional Connector Transit Corridor

The Regional Connector in Downtown Los Angeles is a Light Rail System 1.9 Miles Long that connects the Metro Gold Line to the 7th Street metro Station. Passengers will be able to travel between Azuza & Long Beach and between East LA & Santa Monica on the same train. The Regional Connector has 3 Underground Stations, at 1st/Central, 2nd/Broadway, and 2nd/Hope. AVA has optimized the design of all 3 underground Stations by simplifying the Ancillary Area Layouts, showing functional adjacencies of the Ancillary Rooms both horizontally and vertically, and in doing so, was able to reduce the footprints of the Stations at all Levels. This translated into Station designs that were simpler and less expensive to build. Per direction of our Mechanical Engineers, The Station Vent Fans and associated Rooms and Ducts were removed from all 3 Station designs and the Emergency Fans were configured to perform these functions.

1st/Central station

The Tunnel Vent Fans were relocated from the Lower Ancillary Level Plan of the PE Layout to the Upper Ancillary Level Plan of the Optimized Layout. The High Voltage Switch Gear Room, DWP Room and DWP Switch Room were moved from the Lower Ancillary Level of the PE Layout to the upper Ancillary Level of the Optimized Layout. All major Ancillary Rooms at the Upper Ancillary Level and the Platform/Lower Ancillary Levels of the optimized Plan were laid out side by side and accessed by a common Service/Access Corridor. The Equipment Access Shaft, Service Stair and service Elevator have been placed at one end of this Corridor. By Optimizing the Station Layout, AVA was able to reduce the Footprint of the Upper Ancillary Level Footprint by 27% and the Lower Ancillary Level Plan Footprint by 30% of the PE Footprints.
