Services

Originally established as C.C. Tatham & Associates Ltd. in 1988 and rebranded as Tatham Engineering Limited in 2019, we provide engineering and advisory services to public and private sector clients in a wide range of civil engineering disciplines. From conceptual and preliminary design, through to construction and implementation, we recognize that each project and client partnership is unique.

For each, project delivery must balance client needs and wants, site and environmental constraints, approval requirements, project timelines and project budgets. Our approach to achieving this balance is consistent – through commitment, quality and resolve. Our clients appreciate this and have rewarded us with repeat opportunities – many of our client relations span 20+ years.
