Mott MacDonald’s Empire State HQ: delivery implications for NYC infrastructure engineers
Reviewed by Tom Sullivan

First reported on New Civil Engineer
30 Second Briefing
Mott MacDonald has relocated its North America headquarters to the Empire State Building in Midtown Manhattan to deepen its presence in the New York metropolitan infrastructure market. The move places its transport, water, buildings and advisory teams in a single hub within one of the city’s highest-profile commercial towers, improving access to major clients such as the MTA, Port Authority and city agencies. Co-location is likely to streamline multidisciplinary design and programme management on large urban transit, resilience and building retrofit projects across the region.
Technical Brief
- Move signals continued shift of UK-headquartered consultants’ strategic delivery centres into North American megacity cores.
Our Take
Mott MacDonald’s relocation of its US base to New York sits alongside a run of recent high-value consultancy roles in our database, including the €600M Iarnród Éireann framework and Auckland’s 30+ year motorway plan, signalling a deliberate tilt towards major, long-horizon infrastructure portfolios.
With the Empire State Building as a flagship address in the United States, Mott MacDonald’s profile in North America is likely to support bids similar in scale and complexity to its East Coast Hydrogen FEED work in the UK, particularly as US hydrogen and grid-modernisation schemes ramp up.
