These repairs would <br />include the thorough sand-blasting and cleaning of the <br />surfaces to be capped or grouted. Following <br />satisfactory preparation of the surfaces, an epoxy type <br />gout mixture would be applied. <br />It should be mentioned here that the above <br />corrections require the lowering of the normal pool <br />elevation the reservoir approximately 3 feet, to <br />elevation 473.00, to facilitate dry conditions on the <br />spillway surfaces as well as lower surfaces of the <br />embankment slope protection. The construction cost <br />estimate herein is based on the city personnel lowering <br />the reservoir level by utilizing temporary siphons or <br />the existing raw water pumps. Close coordination <br />between the city and construction contractor will be <br />required. It is further recommended that the design, <br />bidding and construction phases be scheduled around the <br />yearly dry season (summer months) to allow expedient <br />construction during dry conditions and to assure as <br />little fluctuation of reservoir water levels as <br />possible. <br /> <br />9 <br />
