U.S.-based AECOM has secured a key role in the massive $1 billion Sound Transit Modernization in Seattle, Washington. The project entails the expansion of Seattle region’s public transportation system through three Multiple-Award Task Order Contracts (MATOCs). Under these agreements, the company will deliver integrated design, planning and environmental services.

It also entails comprehensive project and construction management (PMCM). The collaboration is strategically designed to accelerate the next phase of planning. Furthermore, it ensures the design and delivery for the Seattle region’s expanding light rail, commuter rail and bus network. The selected firm also further strengthens its position as a key partner in advancing complex, large-scale transit infrastructure programs and other major key rai projects in the U.S.

It does this by providing a comprehensive suite of technical skills that are vital to regional mobility. The selected company, AECOM, will also provide critical support on the PMCM MATOC. It will oversee project and construction management for a wide range of Sound Transit initiatives.

Scope of Implementation on the Sound Transit Modernization in Seattle

As a lead firm on the Sound Transit modernization in Seattle, AECOM is tasked with various responsibilities for the project. For starters, based on the five-year Design MATOC, AECOM will oversee the delivery of civil and structural engineering work. This spans from preliminary engineering to full design development as part of Sound Transit’s regional mobility expansion.

Furthermore, the partnership is aimed at advancing a next-generation transit network for Seattle. It is one one designed to enhance system capacity, strengthen operational reliability and broaden accessibility across the metropolitan area. This specific contract is a cornerstone of Sound Transit’s broader regional mobility expansion. Moreover, it includes a total of 19 MATOCs issued under the program.

Collectively, these agreements are expected to generate approximately $1 billion in engineering services over the performance period. The work will support the expansion and modernization of transit infrastructure across the Seattle metropolitan area. Beyond its lead design role, AECOM will serve as a specialized subconsultant on the Environmental MATOC. Through this it will provide the essential planning studies and environmental clearance activities required to move new infrastructure.
