Agenda 04/09/2024 Item #16C 3 (Award a Work Order to cover unforseen work to Douglas N. Higgins Inc.)04/09/2024
EXECUTIVE SUMMARY
Recommendation to award a $671,400.00 Purchase/Work Order comprised of $621,400 as a negotiated lump
sum payment for the work, together with a $50,000 allowance to cover unforeseen work, to Douglas N.
Higgins, Inc., under Agreement No. 20-7800 Underground Contractor Services, and authorize the Chairman
to sign the Purchase/Work Order for NRO Wells 117N and 119N Improvements - Raw Water Main
Replacement (Project No. 70085).
OBJECTIVE: To maintain reverse osmosis potable water production capability and reliability at the North
County Regional Water Treatment Plant (“NCRWTP”).
CONSIDERATIONS: The proposed scope of work under Project No. 70085, “Wellfield Technical Support
Projects,” is consistent with the FY2024 Budget approved by the Board on September 21, 2023.
The NCRWTP utilizes two groundwater wellfields in the production of potable water. The North Reverse Osmosis
(“NRO”) wellfield supplies raw water to the NCRWTP reverse osmosis process with a maximum potable water
production capability of eight million gallons per day. The NRO wellfield contains 24 wells. A section of the
existing HDPE and PVC raw water mains require replacement due to recent breaks. Approximately 250’ of dual
18” PVC and HDPE raw water mains will be replaced with similar size pipe and approximately 350’ of dual 18”
HDPE mains will be downsized to well 112N. These pipelines will also be connected to new raw water pipelines
being installed on the Vanderbilt Beach Road Extension Project.
Staff distributed a Request for Quotation (RFQ) for the NRO Wells 117N and 119N Improvements - Raw Water
Main Replacement, to the eight vendors on the County’s Fixed-Term Underground Contractor Services Agreement
No. 20-7800. Of the eight vendors notified, four submitted quotations by the February 21, 2024, deadline, as
summarized below:
VENDOR QUOTE
Douglas N. Higgins, Inc. $671,400.00
Quality Enterprises USA, Inc. $788,080.00
Kyle Construction, Inc. $983,500.00
Mitchell & Stark Construction Co. $988,430.00
Quotes were not received from four vendors (Coastal Concrete Products, Haskins, Inc., PWC, LLC., and Southwest
Utility Systems, Inc), for various reasons including their work backlog, current workload, and availability of their
crews.
The lowest total quote received is $671,400.00, which is 12.6 percent lower than the engineer’s cost opinion of
$768,000.00, including allowance. The engineer of record, CDM Smith, Inc., in a memorandum dated February 26,
2024, recommends award to Douglas N. Higgins, Inc., which has performed similar work in this area and has a
satisfactory performance record on previous similar water utility related projects. Staff has determined the lowest
quote is fair and reasonable and recommend awarding the work order to Douglas N. Higgins, Inc.
Douglas N. Higgins, Inc. is a Michigan corporation formed in 1966 and has been authorized to transact business in
Florida since 1973. Douglas N. Higgins, Inc., is currently one of the eight approved contractors on the County’s
annual contract #20-7800 for Underground Contractor Services and has performed work on many Collier County
Public Utilities projects. As with all existing agreements, this 2020 contract will be separately amended to reflect
recent changes to the Florida Law.
Because there may be unforeseen conditions associated with the project, the quote incorporated an allowance of
$50,000.00 (time and materials) to address unforeseen conditions that may be encountered during construction. The
price for any additional work that will utilize this allowance will be negotiated prior to commencement in
16.C.3

GROWTH MANAGEMENT IMPACT: This project meets current Growth Management Plan standards to
ensure the adequacy and availability of viable public facilities.
LEGAL CONSIDERATIONS: This item has been reviewed by the County Attorney, is approved as to form and
legality and requires majority vote for Board approval. - JAK

Memorandum
To: Alicia Abbott, E.I., PMP

From: Mark J. Sunyak, P.E., PMP
Sr. Project Manager
Date: February 26, 2024
Subject: NRO Wells 117N & 119N Improvements – Raw Water Main Replacement
Request for Quotations Under Agreement 20-7800 Underground Contractor Services
Quotations for the referenced project were transmitted to the eight contractors on the Underground
Contractor Services Contract on February 5, 2024. A pre-quote meeting was held via Teams on February
12, 2024. Four contractors submitted proposals on the due date of February 21, 2024. A bid tabulation
is attached for reference.
The lowest responsible and responsive bid was submitted by Doulas N. Higgins, Inc at a total price of
$671,400.00, which includes the additive alternate and an allowance of $50,000.00. The Engineer’s
Opinion of Probable Cost was $768,000.00. The lowest bidder was $96,600.00, or 12.6%, lower than the
Engineer’s estimate. The average total price for all bidders was $857,852.50 which is consistent with the
Engineer’s cost estimate.
The contractor has performed similar work in this area on an emergency basis and is keenly aware of the
ground conditions and the work to be performed for this project. They have performed piping work for
many years within Collier County and have considerable expertise in this specific area.
Based on the contractor’s past performance with similar projects, I am recommending award of this
project to Douglas N. Higgins, Inc. in the amount of $671,400.00.
