ADDENDUM #6 - BID NO. 20260369 – TOM ADAMS BRIDGE STRUCTURAL REPAIRS

BID OPENING DATE: 2:00 p.m. (EST) APRIL 29, 2026

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. These jackets have two types of anodes: a zinc mesh inside the jacket and a submerged bulk zinc anode.

While an underwater inspection helps evaluate the bulk zinc anode's consumption, a proper assessment of

the remaining service life for both types of anodes requires taking current and circuit resistance

measurements, and performing polarization testing. Should this be included in the underwater inspection? If

so, should this be performed for every jacket or a representative sample of the jackets?

A1. Yes, current and circuit resistance measurements and polarization testing shall be included in the underwater

inspection, to determine the remaining amount of anode and service life. Tests should be performed on a

representative sample; the recommended sample is to include one pile per bent, for a total of 16 piles which should

consist of 8 non-structural piles and 8 structural piles.

Q2. When were the jackets originally installed?

A2. Pile jackets were installed in 2006.

Q3. Drawing B1-21. How are 8x8 block attached to the pile or other fender system element? How many bolts are

required per block? Are these bolts epoxied into the pile?

A3. Intent is to match existing condition; per Existing Plans, spacer blocks are spiked to wales.

Q4. Drawing B1-21. Confirm wire rope for pile clusters is per FDOT 471-030 ½” 6x19, 6x25, or 6x37 class IWRC

type 316.

A4. Wire rope for pile clusters shall be 3 strands of stainless steel 6x19-5/8” diameter to match existing.

Q5. Drawing B1-21. Wire ropes for x2 and x3 clusters shown wrapped around the pile in sections A-A and B-B.

Section A-A also shows wire wrapped around the block. Confirm wire ropes should be installed per existing

condition through the holes/pvc sleeves in the back and front piles for x2 cluster and through the hole in the

back pile but wrapped around on the outside of 2 front piles for x3 cluster. None should be wrapped around

the spacer block 8x8.

A5. Correct, install wire ropes per existing condition, not around 8”x8” blocking.

Q6. Drawing B1-21. Confirm 3 new cable wraps for each location top and bottom for both x2 cluster and x 3 cluster.

We believe existing conditions show only 2 wraps.

A6. Install 3 strands of stainless-steel wire wraps at each location, top and bottom. Existing plans detail 3 strands.

Q7. Drawing B1-21. Section A-A show only 1 set of cables for 3 pile cluster. Confirm 2 sets top and bottom required

as per existing conditions on site for both x2 and x3 pile clusters.

A7. Match existing condition on site for 2 and 3 pile clusters.

Q8. Drawing B1-21. Confirm fender concrete pile size is 10”x10”.

A8. Piles were not measured at time of inspection. It is believed that piles are 10” x 10”.

Q9. Drawing B1-21. Confirm for x3 pile cluster section A-A two bottom walers are not fastened to the pile but they

are fastened only at the 2 pile clusters per section B-B. Site pictures from bottom 2 rows fastened to the

concrete pile on existing system at each and both type of clusters x 2 and x3.

A9. Fasten bottom two walers to pile using 7/8” diameter bolts at both 2x and 3x pile clusters.

Q10. Drawing B1-21. To replace the 2 bottom rows of wales we will cut off the existing bolt at the face of the pile.

We will drill new hole and epoxy new bolt in piles to the side/offset of the existing hole. To replace the existing

hardware for the two top rows we will do the same which will leave open hole in the existing waler from

existing removed bolt. The hole from existing hole will stay as is and unpatched.

A10. Patch existing hole before installing new waler beam to avoid corrosion.

Q11. Drawing B1-21. Section A-A third bolt from the top connecting 2 piles in x 3 pile cluster. Are we required to

replace these? And, if yes, how many of these bolts per each 3-pile cluster? What is material and diameter

the diameter of the bolt?

A11. No, it is not required to replace bolts connecting existing piles.

Q12. Fender system. Sheet B1-21 section A-A. Can carriage bolts for the two top rows of wales be substituted for

threaded rod with 2 washers and nuts?

A12. No, carriage bolts shall not be substituted for the 7/8” diameter threaded rod and washer/nuts. Intention is to replace

all hardware in kind.

Q13. Fender System. Sheet B1-21 section A-A third from the top hex bolt connecting two concrete piles. Confirm

this bolt needs to be replaced too. If yes, can you approve for the bid threaded rod with two washers and two

nuts as a substitute for the hex bolt?

A13. No, it is not required to replace bolts connecting existing piles.

Q14. Fender system. What is the height and width of the clearance gauge sign for this bridge? FDOT drawing 471-

030 shows “varies”.

A14. Match existing clearance gauge dimensions. Per the existing plans, the clearance gauge dimensions are 11’-2 ¼“ in

height and 1’-0” in width.

Q15. Drawing B1-21. Section B-B. What is the diameter and length of the bolt attaching wales to piles. Is it 7/8”?

A15. 7/8” diameter bolts; contractor shall ensure the bolts pass through existing/proposed waler beam/blocking and through

existing piles. Estimated length of bolts is 1’-8” per existing plans.

Q16. Confirm all hardware that connects timber to concrete is to be epoxied threaded rod with washer and nut vs

bolt if called/shown on the plans.

A16. All hardware shall match existing plans, 7/8” diameter bolt with nut and O.G. washer.

Q17. Can the contractor provide a comparable alternative for the engine generator other than the ones listed on

TS-15 -B: Materials (Cummins Power, Caterpillar, and Kohler)? These manufacturers are very hard to get to

modify their fuel tanks to accommodate the specs.

A17. The contract documents intentionally limit acceptable generator manufacturers to Cummins Power, Caterpillar, and

Kohler. These manufacturers were selected to ensure compatibility with the specified system requirements, including

performance, reliability, SCADA integration, and compliance with NFPA 110 and project-specific operational criteria.

At this time, comparable alternatives outside of the listed manufacturers are not being accepted.

Q18. What type of certifications must one possess to perform the underwater inspection/report for pile jackets

(cathodic protection system)?

A18. Obtain a commercial diving certification and complete an FHWA-approved Underwater Bridge Inspection training

course (such as NHI Course 130091).

Q19. It is said on the plans that some spall and crack repair may be locating under water. Materials for crack

injection and spall repairs listed on the drawings including reference to FDOT APL are for above water

repairs. Please specify the materials for spall and crack injection repairs for under water.

A19. Underwater grouts and crack injection epoxy, meeting the requirements of FDOT Standard Specifications Sections

926 and 934, can be used.

Q20. Please provide pictures of inside the generator room, if it is not possible to visit inside ourselves.

A20. Please see two (2) photos attached.

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.
