Page 3 of 5 <br />Preliminary Opinion of Probable Cost: The Engineering consultant performed a preliminary opinion of <br />probable cost based on recent projects and industry pricing. The opinion of probable cost was broken into <br />three (3) components as follows: <br />• Proposed Transmission Main <br />• Proposed Distribution Main <br />• Proposed Storage and Re -pump Station <br />Proposed Transmission Main: <br />This portion of the project entails installing a 16 -inch reuse transmission main along the east side <br />of A1A approximately 4,500 linear feet (LF) from the intersection of County Road (CR) 510 and <br />A1A south to the existing SOWWTP (currently not in operation). The consultant's construction <br />estimation for this portion is approximately $1.5 million. <br />Proposed Distribution Main: <br />The subject estimation was to run a 12 -inch reuse distribution and/or transmission main south <br />from the SOWWTP to Old Winter Beach Road along the east side of A1A approximately 8,300 LF. <br />The estimation for this portion is approximately $2.2 million. Although the consultant did not <br />perform any utility locates, geotechnical information, and surveying data, they did compute an <br />opinion of probable cost to run a 12 -inch reuse main from Old Winter Beach Road approximately <br />1000 LF south to Johns Island's existing pump station. The engineers estimated cost for this is an <br />additional $219,000.00 <br />Proposed Storage and Re -pump Station: <br />Proposed installation of a three -million -gallon storage tank and pumping facilities within the <br />inactive SOWWTP. The engineer's opinion of probable cost is approximately $3.1 million. <br />The soft costs, which include fees associated with engineering, surveying, bidding, and construction <br />engineering inspection, are approximately $485,875.00, or 7% of the total project cost. <br />Pending the outcome of today's Indian River County Board of County Commissioners (BCC) decision(s), a <br />preliminary schedule, subject to change, could look as follows: <br />TASK <br />DESCRIPTION <br />ESTIMATED TIME <br />1 <br />Procure Engineering Consultant <br />3 to 6 months from BCC direction <br />2 <br />Biddable Contract Documents & Plans <br />6 to 8 months from notice to proceed <br />3 <br />Recommend award of Contract <br />2 to 3 months from Task 2 completed <br />4 <br />Begin Construction/Pre-Con <br />1 month from Task 3 completed <br />5 <br />Substantial Completion <br />6 to 8 months after Task 4 <br />6 <br />Final Completion <br />1 to 2 months after Task 5 <br />TOTAL ESTIMATED PROJECT COMPLETION TIME FOR THE PIPE LINE <br />19 TO 27 MONTHS <br />TOTAL ESTIMATED PROJECT COMPLETION TIME FOR THE TANK <br />24 -MONTHS FROM NTP FOR <br />CONSTRUCTION <br />According to the consultant's evaluation of the A1A corridor, the constructability of a transmission and <br />distribution main along the east side of A1A is feasible. As part of that investigation, the consultant <br />C:\Users\legistar\AppData\Local\Temp\BCL Technologies\easyPDF 8\@BCL@ B8ODD750\@BCL@ B8ODD750.docx <br />146 <br />
