Introduction

FlatironDragados has been selected by the Los Angeles County Metropolitan Transportation Authority (Metro) to undertake two key projects aimed at improving rail traffic efficiency and expanding transit access for Los Angeles County residents. These projects include preconstruction services for the Southeast Gateway Line Enabling project and the Link Union Station project.

Southeast Gateway Line Enabling Project

FlatironDragados, in a joint venture with Herzog, was awarded the preconstruction services phase for Metro’s Southeast Gateway Line Enabling project. This project involves relocating heavy freight rail lines and utilities to pave the way for a future phase that will introduce 14.5 miles (23.4 km) of new light rail to southeast Los Angeles County. The preconstruction contract is valued at USD 10.5 million and supports early design coordination and construction planning, which is currently in progress.

The overall construction project is anticipated to cost over USD 500 million and will encompass utility relocations, rail installation, construction of one new light rail bridge and one new freight bridge, a pedestrian bridge over the freeway, and a new Metro station at the I-105 freeway. Upon completion, the Southeast Gateway Line project will provide transit access to the cities of Bell, Bellflower, Cerritos, Cudahy, Downey, Florence-Firestone, Huntington Park, Los Angeles, Paramount, South Gate and Vernon.

Link Union Station Project

The second contract awarded to FlatironDragados concerns the preconstruction services phase of the Link Union Station project. This project focuses on modernizing Los Angeles Union Station, which is Southern California’s busiest multimodal transit hub. The preconstruction contract is valued at USD 7 million and supports ongoing collaboration with LA Metro on project design and construction planning.

The overall project aims to create “run-through tracks” on an elevated rail yard to increase Los Angeles Union Station’s capacity by up to 200%, improve transit connectivity, accommodate Amtrak and Metrolink service, and prepare the corridor for future high-speed rail service.

Project Goals

The improvements planned will allow trains to enter and exit from both ends of the station, thereby reducing congestion and increasing operational flexibility. This collaborative delivery project fosters innovation, facilitates problem-solving, and aims to provide greater budget and schedule certainty.

Strategic Approach

These Construction Manager / General Contractor (CM/GC) projects are part of FlatironDragados’ strategy to build upon existing relationships by securing contracts with balanced risk profiles that facilitate collaboration with clients.
