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.)

mailto:[email protected]

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.

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.
