NEW YORK Hudson The Hudson Tunnel Project delivery partner model has been expanded by the Gateway Development Commission (GDC) for the project in New York. As a special-purpose entity with the mandate
to build the Hudson Tunnel Project, the GDC has a limited number of staff by design.

Partners, a JV of Parsons Corporation, Arcadis of New York Inc, and Mace North America Ltd, in March 2024, GDC has: ● secured full funding for the Hudson Tunnel Project; ● awarded contracts for three construction packages, including the first construction project that involves tunnel boring;
● •advanced the first Hudson Tunnel Project construction package – the Tonnelle Avenue Bridge and Utility Relocation Project – toward on- time completion in the coming weeks;
● procured and overseen manufacturing of the two TBMs that will build the section of the new tunnel in New Jersey;
● managed the procurement process for four additional construction packages, including two that will be awarded in the next six months.
The GDC said expanding its use of the delivery
partner model enabled it to retain the team and build on the success so far by adding engineers, project managers, planners, safety experts, and other key personnel, bringing MPA’s support to 350-400 full-time equivalents over the next five years. The resolution allocates up to US$665 million for this new scope of work. The MPA Delivery Partners’ initial contract term ends in 2030, with the option for three subsequent three-year renewals.

They said the approach with a Public-Private
