Our File 0544 <br /> May 14, 2007 <br /> NON-EXCLUSSIVE PROFESSIONAL ENGINEERING AGREEMENT <br /> CONTINUING CONSULTING SERVICES <br /> ATTACHMENT <br /> • Background <br /> As a result of discussions between the Grand Harbor project developers and the Indian River <br /> County Utilities Department, agreement has been reached regarding the proposed 16" Brine <br /> Force Main through the Grand Harbor project between US # 1 and the proposed Spoonbill Marsh <br /> Brine Disposal site. As a result of the agreed force main route alignment, revisions must be <br /> made to the plans which were prepared in accordance with the original contract dated October 4, <br /> 2005 . In addition to the plan revisions, the Utility Department has also determined that it would <br /> be cost effective to also include the design and preparation of contract plans covering the <br /> extension of a 12" reuse main from the Lateral G Canal eastward through the Grand Harbor <br /> property line at the east end of 57`" Street. The design and anticipated simultaneous construction <br /> of both pipelines should result in a better engineered solution and a substantial reduction and <br /> construction costs . The purpose of this Addendum # 1 is to provide for the above described <br /> revisions to the 16" brine force main and the addition of the 12" section of reuse main to the <br /> Grand Harbor project site. <br /> The estimated project construction cost for the revised brine force main route and the 12" reuse <br /> main is $ 1 , 340,000. 00 <br /> A brief description of the Scope of Services for this Addendum # 1 to Work Order # 1 is provided <br /> below. <br /> • Scope Of Services <br /> Task A — Construction Plan & Permittine <br /> Masteller & Moler, Inc. will utilize our existing plans showing the 16" brine force main from <br /> Bent Pine connection east to the Grand Harbor property line at the end of 57`h Street. We will <br /> modify this portion of our plans by adding the design and construction information which will <br /> provide for the construction of a I2" reuse main. The proposed 12" reuse main will connect to <br /> the existing 16" reuse main along the east side of Lateral G Canal and extending east to the <br /> Grand Harbor property line at the east end of 57`h Street. If and where necessary, the location of <br /> the 16" brine force main as shown on the original plans will be relocated in order to <br /> accommodate the parallel 12" reuse main. As with the 16" brine force main, the 12" reuse main <br /> will be crossing the FECRR, Old Dixie Highway and US # 1 before its termination at the Grand <br /> Harbor property line. The total length of the reuse main is approximately 3 ,000 ' and the total <br />
