Consent Agenda Item INDIAN RIVER COUNTY, FLORIDA DEPARTMENT OF UTILITY SERVICES Date: June 2, 2014 To: Joseph A. Baird, County Administrator From: Vincent Burke, P.E., Director of Utility Services Prepared By: Gordon Sparks, P.E., Environmental Engineer Arjuna Weragoda, P.E., Capital Projects Manager Ato Subject: Approval of Work Authorization No. 2014-001 to Melvin Bush Construction, Labor Contractor,for Two 12" Directional Bores to Replace 1,150 feet of 10" AC Water Main and 200 feet of 10" Force Main on US 1 South North of 21' Street SE—UCP#4096 DESCRIPTIONS AND CONDITIONS: On November 12, 2013 the Board of County Commissioners (BCC) approved an Agreement with Young's .. Communication Co., Inc. (Y-COM) to resolve conflicts between existing water and sewer facilities and proposed paving and drainage improvements by the FDOT on US 1 from 11th Street south to the County Line. Y-COM started construction on December 9, 2013 and is still working toward the completion of the project within the 370 days allocated in the Agreement. During the week of May 18, 2014, the FDOT realized that an existing 10" Asbestos Concrete (AC) water main was going to be under the new pavement of US 1 South and requested it be relocated outside of the edge of pavement. AC material is known to be brittle and prone to failure, especially when large vibrating compactors begin to work over the water main during roadway construction. An AC water main break is highly likely under these conditions. Also, field excavations revealed that a 10" PVC force main would be in conflict with a proposed entrance drive to the strip center immediately north of Young's Market. ANALYSIS: Because there are also petroleum contaminated soils in the vicinity of the proposed work, it was decided that the best way to replace the 10" AC water main and 10" PVC force main was to install two 12" HDPE pipes by the directional bore method. A review of the bid item list from Y-COM reveals that there is an item for 12" HDPE directional bore installation. However, the unit price difference between Y-COM and our Labor Contract on the 12" HDPE directional bore installation item is $87.00 per liner foot. Since a major portion of the above described work is related to this item, it was decided to use the Labor Contractor for the work. A cost estimate was prepared using the Labor Contract (See Attachment 1). The estimated costs are $106,000.00 for labor and $60,000.00 for materials for a total project cost of $166,000.00. Work Authorization No. 2014-001 was prepared in the amount of $106,000.00 for labor (See Attachment 2). Page 1 of 2 72
