 RESPONSE: JEA will pay the Right of Way permitting fee directly to COJ.
11. INQUIRY: During the pre-bid meeting it was discussed that JEA will pay for the by-pass pump fuel. Will they also pay
for the dewatering pump fuel?

RESPONSE: JEA will supply fuel for the temporary fuel tanks supplying the bypass pumping system (Phases I
and II only). The temporary fuel tanks shall be supplied by the bypass pumping contractor or general contractor.
Fuel for the dewatering pumps shall be the responsibility of the Contractor.
12. INQUIRY: Who is responsible for filling the new [permanent] diesel fuel tank?
 RESPONSE: JEA will fill the tank. It is the contractors responsibility to notify JEA thirty days prior to the tank

13. INQUIRY: Page 115 shows the water pipe as schedule 40 304ss, page 115 shows water pipe as schedule 10. Are only the
risers to the hose valves schedule 40?
 RESPONSE: The stainless steel piping for the seal water and wash down systems shall be 316 Schedule 10. The
stainless steel piping exterior to the building (for the yard hose bibbs) and all piping for potable water shall be 316
Schedule 40. Refer to Specifcation Section 15140, Paragraph 2.01B.
14. INQUIRY: Will JEA pump down the wet well as far as possible, possibly to the invert of the suction bells, before shut
down for rehabilitation of the interior of the wet well?
 RESPONSE: JEA will pump down the wet well as written in the above inquiry. Refer to Inquiry Note. 4. JEA
requires one day notice to pump down the well as stated in inquiry 4.
15. INQUIRY: Can JEA establish a bid quantity and a unit price on the bid form for removal of the residuals in the wet well?
This way all bidding contractors will be bidding on the same amount of material since it is not possible to quantify at this
time.
 RESPONSE: The material in the wet well depends on the level to which the existing pumps can pump down the
wet well. Assuming the pumps can pump down to a level of approximately 7.5’ from the bottom of the well (the
current operational LWL), the remaining volume to be disposed of is estimated to be approximately 150 cubic
yards. At a level of 5’ depth, the estimated volume is 70 cubic yards.
16. INQUIRY: Can JEA add a unit price on the bid form for deteriorated rebar repair?
 RESPONSE: JEA has added an allowance to the bid form to pay for up to $10,000 in costs for rebar replacement.
The quantities of rebar and associated costs for such rebar replacement will be evaluated by the ENGINEER and
JEA inspector. Refer to this Addendum for further instruction on rebar repair.
17. INQUIRY: Will this project require a security guard 24/7?
 RESPONSE: See solicitation item 2.13.8 (page 57 of 87) and Addendum No. 3 concerning JEA security when
