Triad Engineering, Inc. provided geotechnical drilling services for the preliminary design (30%) of a 5.62 mile section of the Appalachian Corridor H from Kerens to Parsons, WV. The project included 272 borings consisting of 13,647 linear feet of roadway borings and 2,110 linear feet of roadway borings for a total drilling footage of 15,757 linear feet. The subsurface drilling and sampling included both soil and rock coring.
Triad was also responsible for installing all erosion and sediment control measures as well as full reclamation of all drill sites, access roads and all disturbed areas upon completion. Triad also prepared and submitted Erosion and Sediment Control Plans for the project. All work was completed within the agreed upon time frames and project budget.
Challenges and Solutions
The project was in extremely steep and difficult terrain and an environmentally sensitive area with most of the alignment extending through the Monongahela National Forest. Protection of identified endangered plant species and native Brook trout was of utmost importance. Care had to be taken to minimize disturbance, tree cutting, and avoid stream impacts. Erosion and Sediment Control measures had to be installed to minimize sediment laden water from leaving all disturbed areas including access roads and drilling sitesServices Provided:
