February 3, 2016 Mr. Jeff Littrell, Director Okaloosa County Water and Sewer Department 1804 Lewis Turner Boulevard, Suite 300 Fort Walton Beach, FL 32547 Subject: Engineer's Recommendation of Award Packaged Pump Station – Meigs Seminole PS Project Okaloosa County, Florida - Bid No. WS 78-15 Dear Mr. Littrell: Material ONLY bids were received and opened for the "Meigs Seminole Packaged Pump Station” at 2:30 p.m. on January 13, 2016. The Board of County Commissioners received two (2) responsive bids for the project. The project was bid with a Total Base Bid and two (2) Additive Cost Items. The Total Base Bid was for a complete fiberglass wetwell, 110hp 1800 RPM pumps (4 total), guiderails, discharge piping, and level monitoring devices. The Optional Cost Items: ITEM 4 Upgrade to Hardened Metal Impeller (Additive) ITEM 5 Upgrade to Hardened Metal Volute (Additive) Attached is the bid tabulation of the pricing received for the Base Bid Item and the additional Alternate Items for the recent bid solicitation. The project was designed and specified around three pump manufactures, all approved by OCWS. KSB pump supplied by Pump & Process Equipment, Inc.; Flgyt Pump supplied by Jim House & Associates and WILO pump supplied by AAG Services, Inc. Bids were only received from Pump and Process and Jim House and Associates. The base bid for the Flgyt pump was $382,000 and included a zero cost increase for adding the Harden Impeller (Additive Item 4) and a No Bid for the Harden Volute (Additive Item 5) with deliver time of 175-day. All bid specifications were met, except for the impeller type (discussed below).

All bid specifications were met. In review of the proposals it was noted that the Jim House Associates proposal included the Flgyt pump manufactured with the patented “N” impeller design. The bid specifications stated the pump must be able to handle passing a 3” sphere. The Flgyt “N” Impeller work somewhat different and will not allow any type of large solid object to enter into vanes or volute (such as a block of wood or billiard ball). The impeller is designed to keep the impeller vanes clean and handle large stringy solids like a mop head by shearing portions off as the impeller makes each revolution until the matter has been passed. Flygt warranties the impeller for 12 months to be completely clog free, in addition to the 5-year warranty for the pump. All other qualification requirements specified in the contract documents were satisfied by Flygt. Okaloosa County has several projects using Flgyt pumps, including the recent installation at the Camp Rudder PS. I have also included email correspondence between Constantine and the Jim House sales rep on the operation and benefits of the “N” impeller for your use. Pursuant to the bids received for the above referenced project, Constantine Engineering, Inc. recommends that the Okaloosa County Board of Commissioners award this project to Jim House and Associates, they being the lowest and most responsive bid for the combined Base Bid and Additive Alternate Item #4 for a combined lump sum total of $382,000. Total maximum delivery time after receipt of the signed purchase order is 175 days. Constantine does not recommend the selection of the Alternates Items 5, as submitted. Should any questions arise, please do not hesitate to contact me directly at 850.244.8500. Sincerely, Joseph G. Crews, P.E.
