POLB PIER B ON-DOCK RAIL SUPPORT FACILITY DESIGN
2019 - Current
The project will provide the Port with much needed additional railroad infrastructure to remove bottlenecks, stage longer trains in to and out of the Port, and support the growing on-dock rail demand. Port Design Partners, as a sub consultant to HDR, will serve as the Civil Lead and deliver management and civil engineering services from conceptual design through construction for this $870 million dollar project which is scheduled to be completed by 2032. PDP is extremely appreciative of the opportunity to participate on the project and continue its long relationship with the Port of Long Beach.
POLB MIDDLE HARBOR INTERMODAL YARD
2016 - Current
This project included twelve tracks (eight working and four storage) averaging 4,400 feet in length and a total of 75,000 track-ft, making it the largest on-dock railroad facility in the United States. The project includes concept development and estimating for railroad access and facility layout, as well as phased implementation. Intermodal operations were also dynamically simulated (under a separate project) to assess crane operations, rail operations, coning crews, and repair crew conflicts. Port Design Partners was contracted to assist with finalizing the design documents and providing construction support.
POLB DOUBLE TRACK ACCESS FROM PIER G TO PIER J
The project entails expanding mainline access through the Port to Pier J to enhance overall railroad efficiency with supplemental track improvements within the Pier G terminal. The project includes concept development and estimating for railroad access and track layout, as well as phased implementation. As a sub consultant to AECOM, Port Design Partners is responsible for leading the design team in the Deputy Project Manager role. Daily tasks include: design team coordination; design scheduling; construction phasing; design coordination and oversight; quality assurance; and design submittal content.
POLA BERTHS 142-147 ICTF (TRAPAC)
Engineering design services for the Port of Los Angeles's (POLA's) Berths 142-147 Intermodal Container Transfer Facility (ICTF). The ICTF is an automated on-dock rail yard that will be part of the Container Terminal Development program to automate the container yard. The project includes automated wide-span rail mounted gantry (ARMG) crane rail and eight loading railroad tracks, each with a capacity of eight double-stacked platform cars. Nathan served as the project manager for the design team. His responsibilities included oversight of third-party subconsultants and detailed coordination with the Port of Los Angeles' in-house design team. As a sub consultant to Moffatt & Nichol, Port Design Partners is responsible for leading the production and delivering record drawings.
POLA SEA LEVEL RISE STUDY
Sea-level Rise (SLR) Study for POLA to be able to respond to the State Lands commission with a Coastal Resilience Plan. The purpose of the SLR Study is to identify the areas that are projected to be exposed to SLR by 2030, 2050, and 2100, provide an overview of the Port’s asset vulnerabilities, and to present a suite of strategies that will allow the Port to both adapt over time and become more resilient to SLR. As a subconsultant to AECOM, Port Design Partners was responsible for data collection, infrastructure and operations asset inventory, review of inundation maps, development of vulnerability profiles and adaptation strategies, and report preparation.
POLA RAIL DOCUMENT SUPPORT
Railroad engineering support expertise in the development of updated railroad design criteria, standard plans, and maintenance maps. The effort incorporated new American Railway Engineering and Maintenance-of-Way Association (AREMA) guidelines and recent best practices to establish a consistent approach to railroad design across POLA projects. New railroad standard plans were developed to provide guidance and details that can be referenced on future POLA projects. Plan details included typical cross sections, ties and transitions, underdrains, utility casings, special trackwork, crossing modules, derails, striping, and compressed air. New railroad asset maintenance responsibility and quality maps provide POLA with a graphical representation of various railroad asset maintenance responsibilities along with identification of the various classes of track to ensure upkeep matches intended operations.
Word on the Street
"Nathan deSousa served as the Lead Rail Engineer for the Middle Harbor Program for 7 years. Nathan also served as the Design Team Lead for the Pier E Container Yard and Intermodal Yard, Phase 2 Project. Even under tight deadlines, he continually delivered quality work on schedule. What stands out the most about Nathan is his commitment to customer service and attention to detail. In my dealings with Nathan, I felt that he went the extra mile to deliver the best possible product. He was a great asset to our team and I would recommend him for leadership and technical positions."
