<br /> <br />panels. This will be accomplished by removing all <br />loose, unstable material and installing a soil-cement <br />mixture in the void. This material will develop a <br />strength adequate for supporting the new panel and will <br />offer a resistance to erosion not found in the existing <br />soils. the new concrete panels would be constructed of <br />5" thick cast-in-place concrete having a compressive <br />strength of 3500 psi. The concrete panels would be <br />reinforced with 6" x 6" X 6" ga. wire mesh, see Exhibit <br /> <br />lie". <br /> <br />As a result of our inspection, we recommend the <br />replacement of a minimum 22 panels, each with an <br />approximate area of 168 square feet, 3696 sq. ft. <br />total. <br />RESURFACING AND REGROUTING OF DEFECTIVE SPILLWAY SURFACES <br />The existing reservoir spillway consists of a <br />concrete "ogee" type crest with concrete abutment <br />wingwalls located at the approximate middle of the dam. <br />The inspection revealed numerous locations on the <br />downstream face of the spillway where significant <br />spalling and erosion has occurred exposing the <br />reinforcing steel in the structure. Additionally, in <br />various locations on the spillway and abutment <br />structures there are large cavities exposing the <br />reinforcement steel and underlying portions of the <br /> <br />7 <br />
