Mohsen Vaziri


Director of Geotechnics Mohsen Vaziri is a worldclass geotechnical engineer, unrivalled in finding a solution to every challenge and realising the seemingly impossible by expanding the boundaries of construction knowledge, growing our expertise in the field. He is recognised for his technical leadership, client engagement and management skills, refined through exceptional experience over 40 years.

Mohsen chooses to spend more than half his working life directly on projects. He says succinctly,

“At Whitby Wood, engineering comes first. That matters to me. And I’m excited by the team’s ambition.”

Mohsen champions sustainable engineering, combining creative designs for substructure and superstructure, wherever possible incorporating material reuse and modular construction. He’s worked on ground engineering projects all over the world, amassing an enviable portfolio encompassing landmark buildings, super high rise developments, complex urban regeneration, large-scale rail infrastructure and offshore wind farms.

He believes appreciating nature is the first step in understanding geotechnics, “because the earth is not manmade” and all buildings “rely on their foundations — their weakest point, which hardly anybody sees. It’s in the soil; the soil is part of nature, and that makes every project unique.”

Mohsen’s reputation for unflappability is rooted in his calm demeanour and unwavering focus on cracking problems as they arise. He admits, “when I’m working on something challenging, I can’t move away from it. It might be 4:00am and I’ll wake up and think, ‘We should do it like this.’ There is always a solution. … If you enjoy what you do, you’re never going to stop.”

His enthusiasm for complex geotechnical engineering is matched by his passion for team building, mentoring and supporting younger engineers to grow their careers. “The people below me in a firm have always been more important to me than the people above,” he says.
