EDA is a wholly owned subsidiary of the Edmonton-based firm, Al-Terra Engineering. While we collaborate with Al-Terra on many projects, we work independently with our clients, a variety of engineering firms and architects, to deliver design excellence.

Complementary Civil Engineering Services

If a project requires civil engineering consulting, EDA can draw upon the considerable resources of the integrated team at Al-Terra Engineering. Key services include: Water Resource Engineering, Site Development, Transportation Engineering, Urban Renewal, Municipal Engineering, Land Development, and Planning. Learn more.

Community Investment

EDA firmly believes in contributing back to the communities we serve, and providing a hand up for those in need. This philosophy is an integral part of our culture.

Our commitment to charities goes beyond writing a cheque. Each year, led by an employee chair, team members vote to select the Charity of Choice. Everyone then gets involved in supporting that charity – whether it be volunteering, making a personal donation, or buying a ticket to a charitable event.
