The main component of work is the installation of a 450-foot long double line grout curtain into the right abutment. The grout curtain varies from 90 feet to 170 feet in depth below elevation 1206 feet. The grout curtain will extend fifteen feet in to bedrock for the first 170 feet and in to a silt horizon for the remainder of the curtain length. The grout curtain will be comprised of high and low mobility, balanced, stable grouts. Real-time collection of water pressure testing and grouting responses will be required as will near real-time adjustments to grout mixes. The anticipated volume of grout solids to be placed is 20,185 cubic feet. Drilling methods will need to meet the requirements of USACE ER 1110-1-1807. The work also requires the design and construction of a work surface (construction/drilling pad) near the crest of the earthen embankment to accomplish the embankment grouting and a stormwater collection system to prevent runoff into the reservoir. Magnitude of construction for this project is in the range of $10,000,000 to $25,000,000.
