What AET can do for you

We’ll consult with you to understand the unique goals and constraints of your project. Clients count on AET for the investigations and testing needed to identify and evaluate challenging site conditions or environmental contaminants, as well as performance issues with building and construction materials.

We then develop reports, recommendations, engineering solutions, or remedial actions to help you reduce or manage these risks. Our consultants walk you through the data and analysis, providing the technical support you need to understand the costs and challenges of alternative solutions.
