Agenda 07/28/2009 Item #16C13
Agenda Item No. 16C13 July 28, 2009 Page 1 of 13 EXECUTIVE SUMMARY Recommendation to award Bid Number 09 -5267 "Rehab Reactor #1 - SCRWTP" in the amount of $97,400 to Douglas N Higgins, Inc. to complete the rehabilitation of the Reactor #1 at South County Regional Water Treatment Plant. Project No. 71065.5. OBJECTIVE: To obtain Board approval to award Bid Number 09 -5267 to complete the rehabilitation of the Reactor 41 at South County Regional Water Treatment Plant (SCRWTP). CONSIDERATIONS: There are three reactor tanks located at SCRWTP which are used in the Lime Softening Treatment Process. The tanks have a capacity to treat 12 million gallons of raw water per day. These structures basically combine three functions as part of the water treatment process: mixing, residuals recirculation, and sedimentation. Lime and other chemicals are applied to the mixing zone where solids are formed and accelerate the chemical reactions. Through continuous recirculation of the residual solids or sludge, the water becomes more stable and moves upward to flow into outlet chambers. The mixing and recirculation zone is separated from the sedimentation zone by a conical wall inside the tank. The raw water in reactor #1 is penetrating through the tank wall, and moisture and calcification have formed on the outside of the tank. This condition put reactor #1 out of compliance with the Florida Department of Environmental Protection (FDEP), as documented in the attached Compliance Inspection Report dated January 16, 2009, page 6, item 5. The scope of this project is to clean, repair and recoat the interior of reactor #1 to stop the filtration of water through the concrete onto the exterior walls of the structure. The bid for the reactor #1 was advertised on June 6, 2009. Bids were publicly opened on July 1, 2009. The received quotes are summarized in the following table: BIDDER TOTAL Amherst Maintenance Inc. $97,400.00 Douglas N. Higgins, Inc. $97,9511.00 Gulf Coast Contracting, LLC $100,820.00 Mitchell & Stark Company, Inc. $1 18,000.00 Professional Tank Cleaning, Inc. $136,200.00 Spectrum Contracting, Inc. $161 ,006.00 Southland Painting Corp. $220,700.00 Collier County staff's estimate for this repair is $100,000.00 and finds the bids to be fair and reasonable and recommends awarding the contract to the Douglas N. Higgins, Inc for $97,400.00.
