Consent Agenda Item INDIAN RIVER COUNTY, FLORIDA DEPARTMENT OF UTILITY SERVICES Date: April 3, 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 pyo Subject: Amendment No.2 to Work Order No.3 with Kimley Horn and Associates for Design and Implementation of a Lime Softening with Carbon Dioxide Injection at the Two County Regional Water Treatment Facilities UCP 2715 DESCRIPTIONS AND CONDITIONS: On July 17th, 2012, the Indian River County Board of County Commissioners (BCC) approved Work Order No. 3 with Kimley-Horn and Associates, to provide professional services to design and implement a lime softening with carbon dioxide injection at both water treatment plants for a total amount of $ 193,600.00. The work order also included construction phase services for a construction duration of 5-6 months. On January 8, 2013 BCC approved Amendment No.1 to Work Order No.3. This $17,700.00 design effort improves the operational efficiency of the North County RO Facility by automating the permeate degasifier valves and dampers. On May 7th, 2013 the Indian River County Board of County Commissioners (BCC) awarded the contract for the Water Plants Lime Slurry Injection Project to R.J. Sullivan Corporation. Notice to proceed was issued on August 21, 2013 to R.J. Sullivan to start the work at the North and South Water Treatment Plants for a total contract time of 240 -days (60 days were added to the original 180 day duration during the bid process). Change order No.1 to replace the acid tank at the South RO plant was approved by the board on October 8th, 2013 and Change Order No.2 for the west clearwell painting and the replacement of the hardware modules for communication was approved March 18th, 2014. The two Change Orders to R.J. Sullivan added 62 -days to the original contract. Therefore the new total contract time for the project inclusive of the two change orders is 302 days. ANALYSIS: Kimley-Horn and Associates staff has performed the work authorized in Work Order No.3 under construction phase services to the utmost satisfaction of the County. Due to the addition of time to incorporate the changes/additions to the original scope of the project, additional construction phase services are therefore needed. Amendment No.2 also includes design to prepare detailed drawings to extend the existing platforms between the two degasifiers at the North RO plant. These platforms are needed to safely maintain and access the new valve actuators.
