Award - Winning Services

As your Civil Engineering Consultant, our designs and guidance are more than just for permit approval. We can help you create projects that you and your community will be proud of. 


Who We Are

More than just a plan production firm, DeMarr Engineering is backed by industry proven experience from DEMARR Construction, a Class A Heavy Highway Contractor Since 1989. This background gives our firm a unique design perspective on developing practical and effective site plans for contractors to follow.  


With this combination of engineering and construction services under one roof, we have the capability to handle your project from the day your property is acquired to the day of your final occupancy permit. 

Our mission is to provide our clients with a high level of service they can depend on daily to keep their projects running smoothly. In an age of same-day shipping and instant electronic data interchange, we believe consultants should deliver information just as fast. When a client calls or emails our firm, they know we will always answer promptly. Doing our job well, with pride, with honesty, and with efficiency are the simple core qualities that make our company great.
