BOOK 97 PAGE 277 Regional Wastewater Treatment Plants. By constructing this interconnect, we can delay the cost of expanding the North Regional Plant through the year 2001±. - To accomplish this, for a portion of the force main route, we propose to utilize an existing 8 -inch effluent line, which currently runs from the North Regional Plant to Sandridge Golf Course. The 8 -inch effluent line is due to be upsized to a 12 -inch effluent line per the Master Plan, and construction of the new 12 -inch effluent line will be included as part of this project. At the same time, we must install a new line from the canal right-of-way to the effluent receiving pond at Sandridge as we have been utilizing an existing irrigation line, which the golf course now needs to have solely dedicated to their irrigation pumping needs. From the Sandridge Golf Course south, we will construct a new 8 -inch wastewater force main, which will connect to an existing main at the Hawk's Nest Golf Course for conveyance of wastewater to the Central Regional Plant. For details of the Brown and Caldwell analysis, please see the attached letter of recommendation. The engineer for this project will be Carter Associates, Inc., as per our engineering selection and contract rotational procedures. (For details of the proposed contract, please see attached.) ANALYSIS The estimated project construction cost is $685,500.00. The negotiated proposed engineering costs with Carter are as follows: 1) Basic design services $43,000.00 2) Inspection 19,000.-00 3) Survey 11,135.00 4) Soils 1,580.00 5) Public meetings, etc. for Indian River 4.500.00 Farms Total $79,215.00 Contingency* 7,500.00 * To be authorized by the Utilities Director if required. The majority of the route of this project is within the Indian River Farms rights-of-way, and as a result, the District has placed some additional requirements on the project as follows: 1. The County/Engineer must hold a public meeting for all _- property owners along the route (approximately 19 parcels). - (See item 5 under engineering costs for Carter.) 2. The County must provide to the District a "monumented" as - built survey along the District's right-of-way of all existing utilities prior to the District issuing a construction permit. The cost of the "monumented" survey is in excess of $10,000.00, and per our survey contracts, any surveying services over $10,000.00 must be negotiated with our No. 1 selected surveyor, Masteller, Molar and Reed, Inc. The staff has negotiated a cost of the monumented as -built at $10,825.00. Please see the proposed contract with Masteller, Molar and Reed, which is attached. RE902-MMENDATION The staff of the Department of Utility Services recommends that the Board of County Commissioners approve this project and associated engineering and survey contracts as presented. 16 February 13, 1996
