Role description:

Arcadis is seeking a highly skilled and motivated Principal Estimator SME to support one of the most iconic and consequential infrastructure initiatives in the United States — the Gateway Hudson Tunnel Project (HTP). In this role you will be responsible for managing field operations, coordinating multidisciplinary teams, driving safety and quality, and ensuring schedule and budget adherence for one of the largest infrastructure projects in the region.

We are working as the Delivery Partner along with team members and selected by the Gateway Development Commission to deliver this transformative project.. The HTP is a critical component of the broader Gateway Program — one of the most ambitious and impactful transportation initiatives in the nation — and is designed to strengthen mobility, enhance resiliency, and ensure the long-term reliability of the Northeast Corridor.

The project encompasses the construction of a new, two-track rail tunnel beneath the Hudson River, along with the full rehabilitation of the existing 113-year-old North River Tunnel. This vital infrastructure supports more than 200,000 daily passengers via Amtrak and NJ TRANSIT and serves as a backbone for economic activity and connectivity between New York and New Jersey.

This is more than just a job — it’s a once-in-a-generation opportunity to contribute to a nationally significant infrastructure program that will reshape rail transportation, drive sustainable economic growth, and improve regional accessibility for millions. As part of this high-performing, multidisciplinary team, you will help deliver excellence on one of the most technically complex and high-profile projects in the world.
