Specifications include, but are not limited to: The purpose of this Geotechnical Design Report is to present subsurface information and make geotechnical design and construction recommendations for the replacement of an existing approximately 75-foot long, 72-inch diameter corrugated metal pipe (CMP) large culvert (#47000) on Route 164 in Presque Isle. The existing culvert is in poor condition. The culvert is located approximately 0.16 of a mile south of Chandler Road as shown in the attached Location Map. Route 164 is a Highway Corridor Priority 3 road. The proposed replacement structure will be a 114-foot long, 96-inch diameter Polymer Coated Steel Pipe (PCSP) culvert on a skew of approximately 11 degrees to the roadway centerline. The invert of the proposed culvert is approximately 15.5 feet below the existing road grade at the roadway centerline. The roadway embankment slopes at the proposed culvert inlet and outlet shall be no steeper than 2H:1V on the inlet outlet to protect against erosion.
