Agenda 06/23/2020 Item #16C 3 (Contract #15-6469 Work Order: Wells & Water System, Inc.)06/23/2020
EXECUTIVE SUMMARY
Recommendation to approve a $364,619 work order under Request for Quotation No. 15-6469 to
Wells & Water System, Inc., under Project Number 70085, to condition and treat twelve
production wells in the Golden Gate Wellfield.
OBJECTIVE: To complete well rehabilitation by performing well conditioning and treatment
(acidification) of existing Tamiami wells in the Collier County Water Sewer District (“CCWSD”) Golden
Gate Wellfield.
CONSIDERATIONS: The proposed scope of work under Project No. 70085, Request for Quotation No.
15-6469, is consistent with the FY2020 Budget approved by the Board of County Commissioners on
September 19, 2019.
The proposed project consists of injecting an acid solution into selected Tamiami production wells to
provide well bore rehabilitation and well yield improvements. The acid solution dissolves existing
mineral deposits within the well thereby improving well pumping efficiencies, reducing drawdowns, and
providing for higher water production rates.
The proposed well treatment (acidification) will provide needed rehabilitation of the existing wells,
thereby increasing the water pumping rate from each well to the North County Regional Water Treatment
Plant and the South County Regional Water Treatment Plant. Completing this well rehabilitation will
extend the useful life of these existing wells in lieu of constructing new wells.
The County issued Request for Quotation No. 15-6469, “Acidification of Twelve Production Wells -
Phase 4,” on April 23, 2020 and distributed it to all vendors on the County’s Fixed-Term Well Testing,
Drilling, and Maintenance Contract No. 15-6469. Of the five vendors notified, two submitted a quote by
the May 15, 2020 deadline as summarized in the below table.
VENDOR QUOTE
Wells & Water Systems, Inc. $397,608
Layne Christensen Company $659,700
No quotes were received from All Webbs Enterprises, Inc., Naples Well Drilling, Inc., nor Youngquist
Brothers, Inc.
This project is the fourth phase of a multi-phased project to complete all the well treatment rehabilitation
work on the Tamiami Wells. Considering the number of quotes received on this phase, a brief history of
the previous solicitations for the earlier phases is appropriate. The first phase received three quotes,
Wells & Water Systems, Inc., All Webbs Enterprises, Inc. & Layne Christensen Company, from the
County’s Fixed-Term Well Testing, Drilling and Maintenance Contract No. 15-6469. Wells & Water was
the lowest responsible vendor. The second phase received two quotes, Wells & Water and All Webbs
Enterprises. Wells & Water was the lowest responsible vendor. The third phase received one quote,
Wells & Water.
This work is specialized and not every Contractor included in Contract No. 15 -6469 is interested in this
specific type of well treatment rehabilitation project. The low bidder for this phase, Wells & Water
Systems, Inc., has done an outstanding job working with staff to complete the previous well rehabilitation
projects under budget and on-time.
The quote specifications informed the bidders there may be unforeseen conditions associated with the
16.C.3
Packet Pg. 1370
06/23/2020
project. The quote amount incorporates an allowance of $20,000 for owner -directed allowance for work
related to unforeseen conditions including, but not limited to, conflicts with existing facilities not
reflected in record drawings and modifications or repairs resulting from unforeseen utility work
associated with this project. The price for any needed additional work will be negotiated prior to
commencement in accordance with the county’s Procurement Ordinance and the terms of the agreement.
County staff determined the quote to be fair and reasonable and recommends awarding the project to
Wells & Water Systems, Inc. The quote received is approximately 25 percent less than the engineer’s cost
opinion. In its May 18, 2020 recommendation letter, the design professional Water Science Associates,
Inc., recommends awarding the project to Wells & Water Systems, Inc., who has a satisfactory
performance and warranty record on previous, similar, utility-related projects.
FISCAL IMPACT: The source of funding is Water User Fees, Fund (412). The project is expected to be
completed in 2020.
LEGAL CONSIDERATIONS: This item is approved as to form and legality and requires majority vote
for Board approval. -SRT
GROWTH MANAGEMENT IMPACT: This project meets current Growth Management Plan
standards to ensure the adequacy and availability of viable public facilities and to remain in compliance
with all regulatory programs.
RECOMMENDATION: Approve a $364,619 Work Order under Request for Quotation No. 15-6469 to
Wells & Water Systems, Inc., and authorize the Chairman to sign the attached Work Order.
