Bidders are hereby notified that this Addendum shall be made a part of the documents. The intent is to add to, modify, or
clarify the documents. Should any of these items have an effect on price, such changes shall be included in the price bid.
These items have the same force and effect as if contained in the original.
ITEM 1: QUESTION/ANSWER
Q1. We have reviewed Amendment #5, and the answer A2 is very unclear. Please clarify that the LS pay item for
the pile jackets is for a survey and repair plan only. No labor, no material included to repair the pile jacket
deficiencies. It is impossible to quote labor and material of pile deficiencies without a survey done in advance.
Please clarify the intent of this pay item. The sentence ...."and design and repair pile jacket deficiencies" is
not clear, nor can be quantified at time of bid.
A1. Labor and material for pile jacket deficiencies is included in the LS item for pile jacket repairs. Estimate cost of repairs
based on those identified in 2024 Underwater Inspection report. Any additional deficiencies identified through the
underwater inspection performed by the Contractor's Inspector and recommended for repair will be negotiated as
supplemental work upon coordination with and concurrence by the County.
Additionally, Scope Item #14 language is modified as follows:
PERFORM UNDERWATER INSPECTION OF ALL PILE JACKETS (68 LOCATIONS) INCLUDING CATHODIC
PROTECTION SYSTEM.

bearings.
Q4. Can the County confirm that the pile jacket scope is limited to repairs only and does not include full jacket
replacement, and if replacement is anticipated on any piles can you identify which ones?
A4. See attached - the latest inspection report of the cathodic protection. Pay Item 457-70-99 includes the cost for:
d) Inspection of the existing 68-pile cathodic protection system including report with findings and recommendations for
replacement/repairs
e) Repair/replacement plans prepared by the Contractor for review and acceptance by the County. At a minimum, the
cathodic protection system must match the existing cathodic project system.
f) For bidding purposes, the Contractor may use a total of 15 cathodic replacements.
Q5. I am running into issues with the generator; the county did not want to accept a different brand manufacturer
from what they originally specified. To get the size generator with a large enough fuel tank to run 48hrs as specd
it just won't fit through the window to get into the building (that's the big window). We need to see if we can provide
a smaller fuel tank on the genset. What they are asking for just won't work with the current building and footprint.
I'm wanting to get this remedied asap, as time is running out. Thank you much.
The current generator has a 100-gallon tank and the new ones we were getting quotes on are 300-350 gallons to
meet the project specifications. Just to give you an idea on how much larger the new one would need to be. We
will likely have to extend the concrete pad for the generator, which we can do. Getting it into the building, however,
is posing the biggest issue without having to make the window any larger to meet specifications in the genset.
A5. Thank you for the additional information. We understand that the standard factory packaged generator and fuel tank
configuration you reviewed may present installation challenges within the constraints of the existing building.
However, this does not necessarily preclude compliance with the contract requirements. Bidders are encouraged to explore
alternate compliant solutions that satisfy the specified performance criteria, including fuel storage duration requirements
and site access limitations. Such options may include alternate manufacturer configurations, separately supplied fuel tank
systems, custom tank assemblies, manufacturer-approved partial disassembly for delivery, field reassembly after
placement, or other equivalent approaches that meet applicable codes and project requirements.
Bidders should base their proposals on furnishing a complete and compliant system in accordance with the contract
documents. At this time, no revisions to the bid documents are anticipated unless directed by the County through formal
addendum.
This addendum is binding and is to be considered as if contained within the original bid documents of Bid No. 20260369.
Bidders are required to acknowledge receipt of this addendum on their bid forms.

Introduction
In 2006, LifeJacket(R) and submerged bulk zinc anode CP systems were installed on 68
prestressed concrete piles on the Tom Adams Bridge (Bridge No. 010029) in Charlotte
County, Florida. Thirty-six piles have typical non-structural jackets with bulk zinc
anodes, potential monitoring access ports, and two system negative wires. The remaining
thirty-two piles have typical structural jackets with bulk zinc anodes, potential monitoring
access ports, and four system negative wires (one pair of wires is connected to pile
reinforcing steel and another pair of wires is connected to new structural reinforcing
steel). A listing of the piles where CP systems were installed and the type of jacket that
was installed on each pile is shown in Table 1.
Routine monitoring of the CP systems was performed in August 2012. The scope of
work, findings, conclusions, and recommendations are discussed below. At the time of
the 2012 evaluation, the CP systems had been in service for approximately six years.
Scope of Work
The scope of work for the routine monitoring effort was as follows:
1. Conduct a visual survey of accessible CP system components on all 68 piles with
particular emphasis on the condition of the fiberglass jackets and electrical
connections inside terminal boxes.
2. Measure 'on' potentials on all 68 piles using the stainless steel bolt protruding
from each terminal box and an external CSE reference cell placed in the water and
in the access port in each jacket.
3. Conduct the testing described below on a total of four piles with non-structural
jackets and three piles with structural jackets (i.e. 10% of all cathodically
protected piles):
Confirm appropriate continuity of all system negative wires.
Measure the AC resistance between individual anodes and the reinforcing
steel.
Measure the current output from individual anodes and both anodes
combined.
Measure 'IO' potentials with an external CSE reference cell placed at the
same locations where measurements were taken in Item 2.
Measure 24-hour decay potentials at all locations where 'IO' potentials
were measured.
4. Perform any minor repairs necessary on any of the piles.

Findings
A visual survey of the condition of exposed CP system components was conducted on all
68 piles and the findings are summarized below.
The jackets, conduit, terminal boxes, and wiring were all in very good condition. Typical
jackets and wiring are shown in Figures 1 and 2 respectively. The cap on one of the
pumping ports was missing on Piles 3-2, 4-3, 5-6, and 7-4. The caps were not readily
available and were, therefore, not replaced during the routine monitoring effort. One
wire was found with a deficient electrical connector and this was repaired.

jacket (right photograph).
Minor cracking was found in the chamfer area at the top of several jackets and typical
examples of this are shown in Figure 3. In addition, a 5" long x 1.5" wide x 0.5" deep
section of the chamfer on Pile 4-3 was broken away and there was a 8" long x 5" wide
delaminated area on the chamfer of Pile 7-4 (see Figure 4).

At the time that the CP jackets were installed, many of the piles had existing conventional
jackets (i.e. non-CP jackets). To facilitate the installation of the new CP jackets, the
existing jackets were only removed within the limits of the CP jackets (portions of
existing jackets that remained can be seen in Figure 1). Consequently, pile surfaces are
not visible directly above many of the CP jackets. However, during the visual survey of
the CP systems, a few deficiencies were observed on three piles that did not have portions
of conventional jackets in place. These deficiencies included the following:
1. There was an 8" high x 2" wide x 0.5" deep failed patch area at the southeast
corner of Pile 3-1 (see Figure 5).
2. There was a 13 mils wide crack at the southeast corner of Pile 7-1 (see Figure 6).
The crack starts in the chamfer and extends up the pile about 12". There was no
corrosion staining or efflorescence around the crack. In addition to this crack, the
entire east side of the pile, beginning at the top of the chamfer and extending up
14", was delaminated.
3. On Pile 19-1, there was a 16 mils wide crack at the southeast corner (see Figure
7). The crack starts in the chamfer and extends up the pile about 10". There was
no corrosion staining or efflorescence around the crack.
