Response: Yes

Question: Will maintenance personnel be available nightly and on weekends for access to locked rooms?

Response: Means of access will be provided for after hours work, if needed.

Question: On Page E501, detail shows a “Keyed note” #4. –There is no description for keyed note #4. Please Clarify.

Response: Delete keyed note 4 from detail no. 3

Question: If circuit tracing and panel identification option is selected by GSA, will it be incorporated into this contract. Will adjustments be made for project completion dates based on additional work required to be completed?

Response: The Option may be included at time of contract award or by modification to the contract after award. If the Option is included in the award, the completion date will remain unchanged. If the Option is incorporated into the contract by modification, the completion date will be negotiated at the time.

Question: There appears to be a contradiction between Page 41, Paragraph 1.B.2 and Page 42 “Electrical, Water and Gas” as it relates to the contractors responsibility and what the On GSA will provide when relates to electricity, water and gas.

Question: Drawing E501 - In switchboard ES-1, what is the amperage of the feeder to HUM- FDA that is to be removed?

Response: The switchboard referenced on sheet E501, detail no. 3, is switchboard “HIM”. Revise the detail title on detail no. 3 to state “HIM” instead of “ES-1”. “ES-1” is shown on detail no. 1 on this sheet.

Delete the demolition work associated with feeder HUM-FDA. This feeder was previously removed. Revise keyed note 2 to read: “RELABEL BREAKER AS SPARE”.

Question: Drawing E501 - What is the approximate length of the feeder to HUM-FDA that is to be removed, or at what grid lines on the drawings is HUM-FDA located?

Response: Not applicable. HUM-FDA has been removed and does exist anymore.

Question: Drawing E501 - When removing the abandoned feeder, are we to remove the conduit and wire or wire only?

Response: Not applicable. HUM-FDA has been removed and does exist anymore.

Question: Drawing E502 - In MCC-20-1 there are four contactors to be replaced. How many poles does each of the contactors have?

Response: Assume the contactors are 3–pole for bidding purposes.

Question: Drawing E502 - In MCC -20-1, what are the amperages of the two circuit breakers with question marks shown on them, or for bidding purposes what amperage fused switch do you want them replaced with?

Response: Assume the two unknown circuit breakers are 100A, 3-pole. Replace them with 100A, 3-pole fused switch units. Fuse size to be verified per notes on this drawing.

Question: Drawing E602 - In switchboard HIM, what is the amperage of the feeder to HUM-FDA that is to be removed?

Response: Not applicable. HUM-FDA has been removed and does exist anymore.

Question: Drawing E602 - What is the approximate length of the feeder to HUM-FDA that is to be removed, or at what grid lines on the drawings is HUM-FDA located?

Response: Not applicable. HUM-FDA has been removed and does exist anymore.

Question: Drawing E602 - When removing the abandoned feeder, are we to remove the conduit and wire or wire only?

Response: Not applicable. HUM-FDA has been removed and does exist anymore.

Question: Drawing E610 - For all of the panel boards that are to be replaced, are there panel schedules available that show how many branch breakers that are required including the amperage/number of poles for each branch circuit breaker?

Response: There are no panelboard schedules. See the notes on “DFC BUILDING SCHEDULE OF WORK”. Contractor to field verify existing panelboards and breaker arrangements. For bidding purposes, assume any main breakers ratings match the bus ratings of the panelboards. Assume the branch breakers are any combination of 1-, 2-, or

PAGE 6 OF 7 GS-08P-11-JA-C-0045/0002

3-pole and any possible amperage rating available for the type of panelboard (i.e. assume worst case). Assume panelboards may have up to 42 branch poles per section.

Question: Drawing E610 - Are the existing flush mounted panels that are being replaced of a standard size so that the back boxes can be re-used and we would only have to replace the interiors and covers?

Response: See the notes on “DFC BUILDING 20 SCHEDULE OF WORK”. Some are scheduled for complete replacement including back-boxes, and some are scheduled for a new panelboard to be installed adjacent to existing. For bidding purposes, reuse of back-boxes is not permitted as this may not result in maintaining the UL ratings for the new panelboards.

Question: Drawing E610 - The schedule of work shows switchboard HIM with note E that states replace selected feeder breakers and note F that states see sheet E501 for complete scope.

E501 doesn’t show switchboard HIM. How many feeder breakers are to be replaced and what is the amperage and number of poles of each feeder breaker?

Response: As per above responses to Drawing E501 questions, switchboard HIM is shown in detail no. 3 on sheet E501.

Question: Drawing E610 - Note I in the electrical equipment schedule of work calls for a new flush panel board adjacent to the existing panel board. Please verify that the new panel board is intended to be installed right next to the existing panel board, if not please provide a distance that you anticipate between the new and existing panel boards.

Response: Yes, it is the intention for note “I” that the new panelboards are to be installed as close as possible to the existing panelboards.

Question: Drawing E610 - The Electrical Equipment Schedule of Work shows transformer TR- 100 with a 75KVA rating, Drawing E11B and Drawing E601 show it with a 45 KVA rating. Which is the correct rating?

Response: The correct rating is 45KVA. Revise the TR-100 line on “DFC BUILDING 20 SCHEDULE OF WORK” from “75KVA” to “45KVA”.

Question(s): Drawing E610 - The Electrical Equipment Schedule of Work shows switchboard H12 with work note D that reads Trace unknown feeder units, verify ratings of feeder units, update nameplates and remove any abandoned feeders/motor circuits:

How many unknown feeder units are to be traced?

Response: There appears to be six feeders on H12 which need to be verified.

Three of the feeders are not labeled on the switchboard.

T How many abandoned feeders/motor circuits are to be removed?

Response: Unknown. Contractor to field verify as per the note.

What amperage are the abandoned feeders/motor circuits that are to be removed?

Response: Unknown. Contractor to field verify as per the note.

U What are the approximate lengths of the abandoned feeders/motor circuits that are to be removed?
