Amtrak Gateway Program Penn Station District Master Plan 

Provided architectural designs for the reimagining of the New York Pennsylvania Station complex in Midtown Manhattan. The project is part of Amtrak’s systems-level design component of the Gateway Program, which includes construction of a new Hudson River tunnel with a terminus at Penn Station. The master plan for improvements to Penn Station, as well as the surrounding area from Eighth Avenue to Sixth Avenue and 30th Street to 33rd Street, will address longstanding issues regarding life safety, wayfinding, and circulation; integrate the station with various related developments, such as the nearby Moynihan Station; and enhance commercial/retail opportunities. Furnished 3-D blocking diagrams and analyses, 3-D before-and-after renderings, and 3-D vision renderings. He also worked with various disciplines to incorporate rail service planning, pedestrian flow analysis, operations planning, and development opportunities. 

Jamaica Station Future Overhaul and Wayfinding Improvement Program

Developed 3-D renderings and blocking and stacking diagrams for planned improvements to intermodal connections from Long Island Rail Road (LIRR) and New York City Transit service to the AirTrain JFK portal at Jamaica Station in Queens, NY. The project goal is to reimagine Jamaica Station as a transit gateway to JFK International Airport through improvements to level of service and wayfinding such as new signage, upgrades to escalators and elevators, and the reconfiguration of pedestrian corridors. Coordinated with the lead designer to develop preliminary concepts through 3-D visualizations and developed the final visualization materials once a concept was approved by LIRR. He also supported the preparation of the 100% wayfinding drawing set. 

CTDOT Stamford Transportation Center Garage Concept Design

Provided 3D renderings and design for planned new parking facilities at the Stamford Transportation Center in Stamford, CT. The Connecticut Department of Transportation (CTDOT) project is part of a transit-oriented development around the station, which is the busiest New Haven Line station in the state. Responsibilities included design and planning of the proposed parking garage including the undulating- wave perforated metal panel garage screen. Responsible for the design studies to ensure that the project program and garage superstructure fits well in the tight site due to constraints from 1-95 to the north, Railroad ROW to the south, Rippowam River to the West and Washington Blvd to the east.



WP 01 - Phase 2.jpg

Performed design and visualization services in support of the preparation of preliminary engineering plans for a proposed AirTrain people mover system serving LaGuardia Airport (LGA) in Queens, NY and providing intermodal connections at Willets Point. The Port Authority of New York and New Jersey (PANYNJ) project would span 1.5 miles from the airport to the Long Island Rail Road and New York City Transit Mets/Willets Point stations. The scope of work at this initial stage included 30% design. Mr. Barrios’ activities included supporting the preliminary design for three elevated light rail stations; the planned corridor; and an operations, maintenance, and storage facility. He used 2-D and 3-D CAD software and created vision renderings, animations, and blocking and stacking diagrams for presentations and the initial design submission.

LAWA LAX Landside Access Modernization Program

Developed architectural plans, renderings, and visualization materials to support the planning phase of the $5 billion program to enhance ground transportation options at Los Angeles International Airport (LAX) for Los Angeles World Airports (LAWA). The program includes an elevated 2.25-mile-long automated people mover, intermodal transportation facilities, a consolidated rental car center, improvements to the central terminal area, and a connection to Metro. Developed vehicular and pedestrian walkthrough simulations, 3-D diagrams, blocking and stacking diagrams, conceptual plans, and interior/exterior renderings to express the program’s vision and urban design intent. Prepared staging and phasing diagrams –that demonstrated how airport operations would be maintained during implementation of the program.
