December 18, 1995 <br /> <br />Mr. Gerald A. Newton <br />Planning and Development Area Manager <br />Cabarrus County <br />P.O. Box 707 <br />Concord, NC 28025 <br /> <br />Re: <br /> <br />Coddle Creek Reservoir <br />Principal Spillway Leak/Crack Repair <br />RCC Spillway Crack Repair (A03311) <br />HDR Project No. 00187-034-018 (CA) DI <br />HDR Project No. 00187-035-018 (D/S) D <br /> <br />Dear Jerry: <br /> <br />Over the past several weeks and months, we have discussed with NC Dam Safety and a specialty <br />contractor, Underwater Unlimited Diving Services Inc. (UUDSI), a variety of methods for sealing <br />construction joints, repairing leaking joints, and repair of cracks of varying degrees both in the <br />Principal Spillway and the RCC Spillway for the Coddle Creek Dam. The following is a summary of <br />the specific tasks, estimated costs, and expected results. <br /> <br />Task: <br /> <br />Estimated Cost: <br />Expected Result: <br /> <br />Repair of leaking construction joint between Gate Nos. I and <br />2; <br />$5,100.00 <br />The construction joint will be cleaned and sealed on the <br />upstream face. Following repair there will be no evidence of <br />continued leakage through the joint. <br /> <br />Task: <br />Estimated Cost: <br />Expected Result: <br /> <br />Repair of crack in RCC Spillway; <br />$7,855.0O <br />The crack in the RCC Spillway will be cleaned and drilled <br />with angled holes that intercept the crack and injected to <br />completely fill and seal the crack to prevent the intrusion of <br />water/moisture into the structure. <br /> <br />Task: <br /> <br />Estimated Cost: <br />Expected Result: <br /> <br />Repair of cracks in Principal Spillway and abutments <br />showing signs of discharge or efflorescence; <br />$21,000.00 <br />The random cracks in the Principal Spillway and Abutments <br />will be cleaned, filled, and sealed to prevent the intrusion <br />and/or migration of water/moisture into the structure and <br />prevent (reduce) further efflorescence of the concrete. <br /> <br />HDR Engineering, Inc. <br />of North Carolina <br /> <br />Suite 1400 Telephone <br />128 S.
