Shawnee National Forest Rock Stabilization
The Shawnee National Forest is located in the Ozark and Shawnee Hills of Southern Illinois and consists of approximately 280,000 acres of federally managed lands, and is the single largest publicly owned body of land in the state of Illinois.
Federal Highway Administration
$20,000 (KEG Fee)
This project was part of the Federal Highway Administration (FHWA) Eastern Federal Lands Highway Division and included erosion repair, rock stabilization, culvert installation, road reconstruction, resurfacing of aggregate roads, drainage improvements, and other miscellaneous work in Alexander and Jackson counties.
KEG provided continuous construction observation for the installation of twenty-eight ground stabilization anchors to stabilize a steep slope that was formed by an earth slide in the Shawnee National Forest. The project was completed in accordance with FHWA specifications which required a Professional Engineer registered in the State of Illinois to observe installation. The installation involved drilling through the existing soil and rock to a depth of thirty feet, installing a threaded galvanized steel rod, and filling the void with cement grout. The repair area was completed with the installation of a reinforcing steel wire mesh blanket held in place by twenty-eight steel bearing plates bolted to each of the ground anchors. The entire area was completed with a final seeding of native prairie grasses.
KEG inspection personnel were required to produce a log of work performed and a field site daily report, which was submitted to the prime contractor daily. Inspectors also coordinated daily with the prime contractor (Lake Construction), subcontractor (Geostabilization International), and FHWA personnel.
