Consent Agenda Item INDIAN RIVER COUNTY, FLORIDA DEPARTMENT OF UTILITY SERVICES Date: August 28, 2014 To: Joseph A. Baird, County Administrator From: Vincent Burke, P.E., Director of Utility Services Prepared By: Arjuna Weragoda, P.E., Capital Projects Manager AO Gordon Sparks, P.E., Environmental Engineer r Subject: Final Pay to Melvin Bush Construction, Inc. for a 10 -inch Water Main Replacement and a 10 -inch Sewer Force Main Replacement Project in US 1 South from Highland Drive to 21st Street SE, UCP 4096 DESCRIPTIONS AND CONDITIONS: On June 10, 2014 the Indian River County Board of County Commissioners (BCC) approved Work Authorization No. 2014-001 for a Labor Contract with Melvin Bush Construction, Inc. to replace 1,000 feet of 10 -inch Asbestos Cement (AC) water pipe, and 200 feet of 10 -inch PVC sewer force main pipe north of 21' Street SE to Highland Drive at a cost of $106,000.00. A major portion of the existing water main would be located under the new north bound lanes of US 1 now under construction. Because of the brittle nature of AC pipe and its history of failure, FDOT's design engineer requested that it be replaced with modern, more stable materials. A 200 -foot portion of PVC sewer force main that was replaced during an earlier project was in conflict with a proposed entrance drive to a strip center at Highland Drive. ANALYSIS: The replacement project is now complete and Melvin Bush Construction, Inc. submitted Final Pay Request for $80,250.50 (See Attachment 1). The actual labor cost of $80,250.50 is $25,749.50 less than budgeted. The lower cost was realized mainly due to underground conditions preventing about 250 feet of directional bore water main from being constructed and eliminating air release valves as a result of changing from directional bore to trench installation method. However, the section of AC water main that had to be left in place was outside of the proposed pavement of US 1 which is the reason for the water main replacement in the first place. The payment of $80,250.50 to Melvin Bush Construction, Inc. will release the County's obligation to the Contractor. FUNDING: Funding for the utilities replacement project is available in the Utilities fund Account Number 471235436-044699-13502. Funds for this project are derived from the renewal and replacement budget in the operating fund. The operating fund budget is derived from water and sewer sales. 171
