Our File # 0831 LG June 27 , 2011 NON -EXCLUSIVE PROFESSIONAL ENGINEERING AGREEMENT CONTINUING CONSULTING SERVICES AMENDMENT # 1 TO W0# 13 " EXHIBIT 1 " The Indian River County Utilities Department has decided to amend Work Authorization # 13 which was approved by the Board of County Commissioners on October 21 , 2008 . The original project involved Engineering Services in connection with conversions of an existing 16" brine main , an existing 12 " force main , and an existing 12 " potable water main to reuse mains . The Brine Main Project' s design/as- built drawings were used to design the proposed connection between the brine line and force main just west of the beginning of the Wabasso Causeway (SR 510 ) . The original design plans for the brine line reveal the existing force main to be located to the south of an existing Johns Island irrigation main and next to the existing brine mains . In the field , however , Contractor' s excavations have revealed thhe f,,��"" a ai to be located north of the existing irrigation main and under the existing SR .n ei�sW i banes . The irrigation mains position between the existing brine main and force main requires a change to the proposed connection between reuse facilities . This Amendment , therefore , provides for Engineering Services to modify the design of the brine/force main and brine/water connections including structural engineering for design of pipe stanchions to support 12 " , 16 " , and 18" diameter pipes to be placed on the most westerly headwall beneath the Wabasso Causeway . The additional services covered by this Amendment # 1 to the project will generally consist of the following revisions to the original project : • Scope of Services L DESIGN SERVICES Task A — Reuse Main Improvements 1 .
