Addendum No. 1
Please review the following changes/additions/clarifications to Invitation to Negotiate (ITN) No.
14-15-MH Campus Recreation Pool Renovations and Repairs to be addressed in submitted
proposals:
Below is USF’s response to the questions that were discussed at the Pre-Proposal Meeting on February
4, 2014. Any additional questions from prospective vendors must be submitted via email to Michael
Hernandez mahernandez@usf.edu no later than 3:00pm on February 11, 2014.
USF Response to Vendor Questions from Pre-Proposal Meeting for ITN 14-15-MH
1. Is there a specific brand of VFD that the contractor must use? Response: No, all equipment will be new
so the new VFD must interface with the new equipment and with the existing DCM5 control system.
2. Is the contractor responsible for the asbestos abatement in the pools below surface viewing window?
RESPONSE: No, USF will engage an asbestos abatement contractor for this purpose, but the pool
contractor will be responsible for resealing the viewing window. (See item #21 below.)
Addendum #1
3. Are the sealant specifications in the project manual? RESPONSE: USF has updated the sealant
specifications in the Project Manual and a revised specification for Section 07 92 00 Joint Sealants is
attached with this addendum. All changes are indicated bold, underlined xxxxxxxxxx for additions.
4. Will contractor replace all the old plumbing? RESPONSE: contractors should replace plumbing if is it not
working properly or if piping modifications are required due to the equipment reconfiguration.
5. Where is the leak that needs to be fixed? RESPONS: USF had a plumbing contractor run a camera into
the pipe that is leaking which showed that the leak is approximately 10’ from the west wall of the
building at the SW corner of the pool.
6. Does USF have a copy of the video showing where the leak is? RESPONSE: No we do not have a copy.
7. Once the epoxy is removed there will be some loose material left behind, does USF have a preference as
to how the contractor removes the loose material, sand-blast or hydro-blast? RESPONSE: USF will leave
that up to the Contractor.
8. Is USF changing the filtering system from a DE system to a Vacuum Sand high rate system? RESPONSE:
The intent of the Project is to change the system to a Pressurized Sand filtration system. The
Specifications are correct, as originally issued; Specifications Section 13 11 00 of the Project Manual is
being re-issued with this Addendum to provide minor clarifications. All changes are indicated by either
strikeout for deletions xxxxxxxxx or bold, underlined xxxxxxxxxx for additions.
9. Is USF requesting proposals for new VFD drives for the motors and a fully automatic system? RESPONSE:
Yes that is what we are requesting.
10. Do contractors need to replace tiled lane markers? RESPONSE: Yes the lane markers must be re-tiled,
but USF is eliminating the north and south lane lines.
11. Does USF want to change to a salt water system? RESPONSE: USF has requested this as an Add Alternate
to the Base Bid. See Specifications Section 13 11 00-2.05.
12. Has a specific ozone treatment system been specified? RESPONSE: No. Provide a system designed and
sized to treat the size of the pool and the flow rate of the filtration system. See Specifications Section 13
11 00 – 2.04.
13. Is this a Health Department-regulated pool? RESPONSE: Yes it is. The Contractor will be required to
obtain permitting through the DOH.
14. Is the contractor responsible for providing the engineering plans? RESPONSE: Yes the Contractor is
responsible for providing the engineering, signed and sealed construction plans and the construction
aspects of the project.
Addendum #1
15. How deep is the foundation of the diving board pedestal? RESPONSE: we do not know the exact depth,
but the pedestals for the other two diving boards came out without any issues. Patching of the existing
deck will be required suitable for mud-set tile to be installed.
16. Which tile around the edge of the pool needs to be replaced? RESPONSE: All tile on the pool side of the
existing beam. See photographs following for clarification. Refer to Specifications Sections 13 11 00 2.12 and 2.15.
17. Is USF seeking a vacuum sand filtration system or a pressurized system? RESPONSE: See item #8 above.
18. Where will the pressurized sand tanks be placed, and how large is this space for the tanks, and what
type of access is there to get into the space? RESPONSE: The tanks shall be placed in the room adjacent
to the Pool Equipment Room - #M0015.
19. Which plumbing in the mechanical room will the vendors need to replace? RESPONSE: See item #4
above.
20. What is the horse power of the pool pumps and how many pumps are there? RESPONSE: The existing
pumps are 10 HP, and there are 2 existing pumps.
21. As a part of the Base Bid, the existing underwater observation window is to be re-sealed. As an
Alternate (#5) Contractors may elect to provide an adjustment to remove the existing window in its
entirety and fill in the existing opening with structural concrete and reinforcing, dowelled and secured
into the existing pool walls, prior to application of the pool interior finish. Finish the area to match other
pool wall surfaces as if the window did not exist.
