What AET can do for you

Our Williston team members offer a varied scope of resources that assist clients in identifying and evaluating challenging site conditions, geological hazards, environmental contaminants, and performance issues with building and construction materials. Using these resources, we develop recommendations, engineering solutions, or remedial actions to help you reduce or manage these risks.

North Dakota’s harsh climate brings unique challenges to the energy sector in maintaining oil pads and access roads across the state — it’s our mission to develop lasting solutions for these challenges in an encompassing and timely manner.

We value the relationships we are able to develop with clients. These connections lead to better understanding of your needs, which allows us to provide you with the highest quality of work and bring value to your projects.
