30 Second Briefing
Mott MacDonald has added North America president and CEO Dean Radeloff and northeast US division general manager Aimee Barwick to its executive board, increasing direct US and Canadian representation in group-level governance. Radeloff, who joined in 2022, brings heavy civil infrastructure, engineering, design and construction experience across multiple US and Canadian markets. Barwick, with a track record on large-scale infrastructure and urban development projects in New Zealand and North America, has been leading integrated regional teams and client relationships across the US northeast.
Technical Brief
- Governance change explicitly brings North American operational leadership into group-level decision-making structures.
- Radeloff’s remit covers engineering, design and construction delivery across multiple heavy civil infrastructure markets.
- Barwick’s track record includes complex large-scale infrastructure and urban development schemes in New Zealand and North America.
- As northeast US division general manager, Barwick has overseen integrated regional teams across multiple disciplines and offices.
- Her role has focused on growth, cross-business integration and key client relationship management in the northeast corridor.
- Radeloff has led recent expansion of Mott MacDonald’s commercial footprint across US and Canadian infrastructure sectors.
- For geotechnical and civil teams, closer North American board input should align corporate risk appetite with local project conditions.
Our Take
Mott MacDonald’s move to deepen US board representation sits alongside its recent acquisition of Australia’s Leed Engineering & Construction, signalling a push to align governance with a more geographically dispersed delivery footprint across North America and Australasia.
In our infrastructure database, Mott MacDonald increasingly appears not just as a designer but as a programme partner, for example on Transport for London’s Professional Services Frameworks 3 and National Highways’ Water Quality Plan, so stronger US leadership is likely aimed at winning similar long‑horizon frameworks in the United States and Canada.
