1) Is this a follow-on requirement? If so, could you please provide the incumbent contract number for this opportunity? If not, is this a new requirement?

This is a new requirement

2) Will there be a site visit?

Please refer to the solicitation:

A site visit will be held on 26 Jan 15 at 09:00AM at the 2d Contracting Squadron, 801 Kenney Ave, Suite 2300, Barksdale AFB, LA 71110. Please contact Mrs. Barbara Makamson at (318) 456-2430 to confirm attendance and number of personnel attending.

3) In the SOW for the above referenced project refers to drawings, how do we get a set of these to use for this project?

The drawings have been added as of 22 Jan 2015.

4) Can we assume that there is enough length on the existing primary cables to terminate to the proposed Vista switch PMSl0-4840.

No pull new primary (concrete encased duct bank) to closest source. #1, #12

5) How long of a shutdown will be given to replace the existing PSMl0-4840 with a new Vista switch. (It is the Contractor’s understanding that the existing concrete pad is not large enough, the existing conduits will need to be shifted, all terminations will need to be changed and the counterpoise will need to be extended.)

#6 SOW/Minimize outage time. When time comes the Contractor will propose outage plan for approval.

6) Will the Government allow for the roadway to be bored or will the roadway need to be cut and re-poured?

Saw cut roadways. Civil SOW was added (posted on 2 Feb 2015)

7) Contractor did not see where the SOW calls for pathways for the CATV or phone lines that will be removed when the poles come down. Will pathways for these lines be a part of this contract?

No, this is the responsibility of the user. The Contractor does need to coordinate with all involved to lessen outage time before demo.

8) Light fixtures are mounted to the poles that are to be removed. Will new street lights be a part of this contract?

No street lights, exit door lights instead. See item #2, page 3

9) It was mentioned at the site visit that the contractor can utilize the existing abandoned manhole as part of this project. Will this be added to the SOW?

Yes, it was added. See #14 in the revised SOW (posted 2 February 2015)

10) Where will the new 1600AMP switchboard be located?

MDP will be located inside new electrical room. See paragraph 1, page 2 of the SOW

11) The SOW does not state which panels will need to be replaced. Will the Government provide a list and location of the required new panels?

Please see the revised SOW (posted 2 February 2015), first paragraph on page 2 – replace all electrical equipment

12) Can the manhole be changed to 8’x8’x8’?

Yes, see #13 of the revised SOW (posted 2 February 2015)

13) NEC does not allow unfused electrical service to be run thru a building, unless concrete encased. What is the desired solution to correct this?

Please refer to the revised SOW (posted 2 Feb 2015)

14) During the site visit, Base CE indicated that the existing manhole at the north end of building 4186 could be used instead of supplying new manholes 2 & 3. Is this correct?

Please refer to the revised SOW (posted 2 Feb 2015)

15) Can directional bore be used for duct crossings at Wilbur Wright and Rickenbacker?

Please refer to the revised SOW (posted 2 Feb 2015)

16) It appears that the 8 panels shown on sheet E-3 are to be re-fed from the new mdp.

The two training room panels are to be replaced with new. Is the alternate price for five additional panels the remaining 5 panels shown on sheet E-3?

Please refer to the revised SOW (posted 2 Feb 2015)

17) Please clarify the following statement from page 2 of the SOW. Is the intent to provide all new power panels? Is the intent to replace panels near life expectancy?, or is the intent to price the replacement of the five panels shown to be existing on sheet e3

Please refer to the revised SOW (posted 2 Feb 2015).

Also, the Contractor shall provide all new power panels and all new main feeders from new 1600 AF/1200AT, 120/208 V, 3Ø, 4W switchboard to all new or existing panels. Also, contractor shall remove the existing panels in the training room and install new panels in the new electrical room in the corridor. If the panel is near the life expectancy, the Contractor shall change it. The Contractor shall provide line item estimate for providing and installing additional five (5) new panels. The Contractor shall demolish all existing unused boxes, switches, boxes, switches, gutter, conduits, wiring from training room and other area and remove associated conduits and wiring all way to the source of supply.

18) As the SOW calls for coordination study, arc flash study, and short circuit study, are the fault currents for feeder 10 available?

19) Is there a standard for the “pull box”?

Pull box example (Oldcastle or equivalent) added as attachment on 3 Feb 2015.

20) The duration is listed at 180 days. Can this be extended, as the switches are long lead time?

For long lead items, two Notices to Proceed can be issued. One for materials and one to start work.

21) Based on the site visit findings, is there any possibility that the statement of work and scope of work can be changed to incorporate all the ‘unknowns’ that were discovered during the walk through?

22) Per NEC a disconnect switch (fuse) will be required between the transformer and the switchboard. Where will this disconnect switch be installed? The statement of work does not address this.

23) Regarding the area currently occupied by the AF Museum, how much of the existing service do you want removed? At site visit, open junction boxes, existing conduit and wiring were visible, but it was not explained what part of this existing service would be removed under the SOW.
