Our history

WT has a proud history of evolving with changing times and seizing opportunities to help our clients shape built environments around the globe. 

Our story begins with two quantity surveyors starting their practices on opposite sides of the world: Terry Wolferstan in Australia in 1949 and Len Trower in the UK in 1951. Their paths converged in 1961 when Trower journeyed to Australia, met Wolferstan, and the two agreed to merge their businesses across the hemispheres. This partnership has grown into the WT we know today. 

Since 1949, WT has partnered with clients to provide accurate, independent and trusted advice. Today, we’re a leading international cost management and advisory firm with 2,000+ people across 70+ offices – proud of our long, strong reputation and excited to lead our industry into the future. 

Trailblazing advisory in North America

The North American business began in 2010 with the establishment of WT’s presence in Mexico City. In 2015, WT won a landmark $1.3 billion public–private partnership project for the University of California – and has since expanded operations as one of the most innovative and fastest growing advisory firms across the US and Canada. 

Looking to the future  

The future of WT is underpinned by investment in our people, our services and our processes. Across all regions, WT takes pride in a client-first approach and consistent results, delivered with integrity. 

We continue to diversify and innovate, including service offerings across the full lifecycle of building and infrastructure projects, leveraging the power of the latest digital technologies and tools to deliver even more accuracy, efficiency and insight to empower our clients to grow.
