Att 02_140P8420R0004_Project Specifications_rev072020.pdf Att 03_140P8420R0004_Construction Drawings_rev072020.pdf

The summary of the changes is a single propane tank and a 45kW generator instead of an 80kW generator and associated specs.

Question 9: THE FIELD DIRECTIVE REDUCED THE STANDBY GENERATOR FROM 80 KW

( AS PER ORIGINAL SOLICITATION ) TO 45 KW. THE SERVICE TO BRANDY CREEK

WASTEWATER TREATMENT PLANT IS 200 AMP 120/240 VOLT 3 PHASE WITH A 22K AIC.

REDUCING THE STANDBY GENERATOR TO 45 KW WOULD RESULT IN PROVIDING

ONLY 100 AMPS OF BACKUP POWER TO THE TREATMENT PLANT. IS THIS THE INTENT?

Answer: Yes, that is the intent. Several of the loads will not need to run on emergency power.

Question 10: THE NOTE IN THE PANEL SCHEDULE STATES, “MAXIMUM ALLOWABLE AIC

IS 22 K AMPS, PANEL MODIFICATIONS WILL BE REQUIRED ( NOT BY CXT ) IF

TRANSFORMER CAPACITY EXCEEDS 175 KVA. DOES THE TRANSFORMER EXCEED 175

KVA ?

Answer: NPS is verifying to determine if transformer capacity exceeds 175kVA. Until NPS verifies and for the purpose of submitting proposals please assume no modifications are necessary.

Question 11: SHEET E01 DETAIL 2 IS THE ONE-LINE DIAGRAM. A CIRCUIT LABELED R&A

PUMP IS SHOWN. IS THAT THE CIRCUIT FOR THE NEW SUMP PUMP AS SHOWN ON

SHEET C02 KEY NOTE 2 AND SHEET C03 DETAIL A.

Answer: No, the R&A pump is for the recirculation and Aeration pumps. The sewage pump will connect to the existing 70A office building circuit.

Question 12: SHEET E01 DETAIL 2 IS THE ONE-LINE DIAGRAM. SHEET B28 IS THE

ELECTRICAL PANEL SCHEDULE PROVIDED BY THE BUILDING SUPPLIER ( CXT ). THE

AMPERAGE REQUIREMENT FOR THE HOT WATER HEATER IS 100. ON SHEET E01 THE

CIRCUIT FOR THE OFFICE LAB IS 70 AMP. THE CIRCUIT NEEDS TO ACCOMMODATE 100

AMPS.

Answer: Due to this RFI, NPS is aware of the issue and is in the process of rectifying the design. Once a solution is determined, NPS will post an amendment with the design edits.

If the design edit occurs after the due date of the proposal, contractors should bid on the contract as is without making presumptions on the needed adjustment. Following contract award, NPS will modify the design and contract to accommodate the change and any associated incurred cost to the contractor to address the issue.

Question 13: THE PERIOD OF PERFORMANCE FOR THE PROJECT IS: 09/14/2020 to

03/13/2021. CXT IS THE BUILDING SUPPLIER AND THEY WILL PROVIDE TWO

QUOTATIONS. THERE ARE TWO DURATIONS FOR MANUFACTURE THAT INCLUDE TWO

COSTS. DURATION NUMBER 1 IS 90 DAYS AND THE COST IS TWICE THAT OF

DURATION 2 OF 150 DAYS. TO MEET THE CONTRACT REQUIREMENT OF 180 DAYS;

DURATION 1 WOULD HAVE TO BE USED PUTTING THE PROPOSAL OVER THE PRICE

RANGE ( FAR 36.204 ).

Answer: NPS prefers duration 2 and will augment the contract requirement for 220 days.

Question 16: Sheet C01 note 14 states that “existing underground site power to new operations building, terminates in electrical pull box.” During the site visit it appeared that the conduit that went back to the new transformer was empty. Please advise.

Answer: There are no conductors or "power" to the pull box. The pull box, near the building site, is there to mark and protect the termination point of the 2" electrical conduit running from the meter panel for the new building. The pull box should be removed, This conduit needs to be coupled to and continued approximately 30 more feet and stubbed up into the location for the new buildings electrical panel. Then approximately 300 feet of conductor cable will need to be pulled through the conduit to provide power from the existing circuit breaker in the meter panel to the new buildings electrical panel.
