LA Metro Regional Connector @ 2nd/Hope – Grand Av Arts/Bunker Hill 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.
Grand Av Arts/Bunker Hill Station
The Auxiliary Power Room of the PE Design was moved from the upper Ancillary Level to the Ancillary level in the Optimized Plan. The Auxiliary Power Room with their Battery Rooms, the TC&C Room with its Battery Room were consolidated at the Ancillary Level of the Optimized Plan. The DWP Switch Room, DWP Metering Room and Traction Power Substation were consolidated at the Upper Ancillary Level of the Optimized Plan. 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. An Equipment Access hatch serving both Levels has been placed close to the Center of this corridor. By Optimizing the Station Layout, AVA was able to reduce the Footprint of the Upper Ancillary Level Plan Footprint by 19%. Though the reductions of the Footprint Areas at the Concourse and Platform Levels was not significant, the Footprints were simplified and the bumps removed from the outer walls.
