Construction Projects

“STONE is an instrumental part of our team on the Portsmouth By-Pass Project: the 16-mile new construction project, which is the single largest project in ODOT history. This project has come with more than its share of environmental challenges. STONE has delivered over 30 full environmental clearance reviews and reports we have requested as part of the project, handling them from start to finish in a very timely & cost effective manner. Furthermore, they’ve proven themselves as an extremely valuable resource when it comes to consulting on mitigation efforts, hazardous materials, and resolving various unknown environmental situations that the project has encountered.


From the top down STONE has proven they are committed to excellence and we look forward to working with them on many projects in the future.”
