What we do

Tatham Engineering is a team of multi-disciplinary project managers, engineers, technical staff and industry professionals who have been challenged to provide consulting engineering, design and construction services relating to the fields of Coastal, Land Development, Municipal, Structural (Buildings and Bridges), Transportation, Water Resources, Water & Wastewater, Mechanical and Electrical engineering.

Originally established in Collingwood, where our head office remains, we also operate through offices in Barrie, Bracebridge, Guelph, Orillia and Ottawa.

How we do it

Employee-owned and community-driven, we are invested in each project regardless of whether it is large or small, in its infancy or nearing completion, simple or complex.

Our goal, for each and every project, is to not only meet but exceed client expectations through project execution and delivery. In doing so, we draw from our 35 years of experience and our valued relationships with approval authorities, agencies and stakeholder groups to maintain project momentum and ensure solutions are cost effective, readily achievable and amenable to all.
