Senior Project Manager Collier County Public Utilities 3339 Tamiami Trail East, Suite 303 Naples, FL 34112-5361 RE: Recommendation for Contractor Selection Acidification of Eight Production Wells, Golden Gate Wellfield, RFQ 15-6469-4 Dear Mr. Bullert: Water Science Associates, Inc. has reviewed the contractor bids for the Lower Tamiami well acidifications (Collier County RFQ 15-6469-4). Two contractors, Wells and Water Systems and All Webb's Enterprises, submitted their quotes for the project. The Contractors'cost breakdown for each of the eight wells is provided in the table below. Wells Wells and Water Systems All Webb Section 1/Well 31 $63,224 $64,700 Section 2/Well 33 $70,724 $81,700 Section 3/Well 3 $70,224 $77,700 Section 4/Well 10 $61,824 $61,200 Section 5/Well 21 $61,824 $61,200 Section 6/Well 28 $70,524 $77,700 Section 7/Well 29 $69,824 $77,700 Section 8/Well 34 $61,524 $61,200 Total $529,692 $563,100 As noted in the table, Wells and Water Systems provided the lower of the two quotes received. The Wells and Water Systems overall total was lower than All Webb's overall total by about$33,000. Both the bidders are qualified to perform the work elements described in the technical specifications that was part of the referenced RFQ. Based on their qualifications, past successful work for the county on similar projects, and apparent low bid, we recommend that the project be awarded to Wells and Water Systems. Note that the Engineer's Estimate to complete the scope of work was $694,400 for 8 wells, which was a conservative estimate. The Contractor's bids were within 6% of each other and the low bid was over 20% below the engineer's estimate suggesting consistent bidding between the contractors and specifications that were understood and appropriately descriptive of the work. 16C 9 The RFQ Form submitted by the lowest bidder is attached to this letter. Should you have any comments or questions, or require additional information, please do not hesitate to contact Kirk Martin or Rahul John via phone or email. Sincerely, id, "...: lei2 ht i W.
