FIRST LIST

1. E2.1 General Notes New Items to be Bold. Below 602 is a 12/240 Transformer connected to pole 2F-4 and another 12/240 50KVA Transformer. Are these to be new or do we follow E1.1 Note 2 & 3 to remove?

Re: Apparent confusion should be resolved by attached drawings.

2. E2.1 shows the existing poles in bold. E1.1 General Notes “C” Remove Power Poles unless noted otherwise. Are these poles to be removed?

See attached E2.1.

3. E2.2 Bold is not very prevalent.

See Attached E2.2.

4. E2.2 Note 2 at top match line calls for new conduit to what? How far? Or do we follow Note 5 on E1.2 as being existing?

See Drawing E2-2 attached.

5. E2.2 Between Bldg 609 & 610 there is a missing item, switch or Sectionalizer to terminate the east 4/0 to the west 4/0 and to the two 1/0 transformer feeds.

See attached E2.2.

6. E2.3 NE of 697 need coordination with future RAP CON/Tower power.

See attached E2.3”

7. E2.4 Transformer shown between driveways to 607 parking lot 1P is not at that location it is south of the south driveway. E1.4 says existing transformer to remain & remove feeder. How is this transformer to tie in to the grid at its present on site location?

See attached E2-4.

8. E3.2 & 3.3 Note 4 30’ KLAXON poles. Do you still have that system in place? Do we supply the new poles?

Delete work referring to KLAXON POLES.

9. In general are all of the Power and Comm. to share a common trench?

They are presently shown in a somewhat different location.

There is only one short section south of building 610 where Communications is separated from the power trench.

10. E4.1 are we to supply the CATV Distribution Cable?

See Specification Section 16375 page 27 starting at paragraph 3.9.1. which has a sentence that starts “Contractor shall be responsible for all labor and material costs to completely install….

11. E4.2 & 4.3 shows all new Comm. E2.2 & 2.3 show some MH. Has there been Comm. placed in these areas?

Some MH are existing. Work in this contract shall use new duct and handholes.

SECOND LIST

1. E2.1 has no scale on the drawing See attached E2.1

2. E2.1 Note 3 shows the transformer connected to a pole 2F-5. E5.2 shows Bldg 602 transformer connected to the same Sectionalizer as Bldg 668.

Do we add the footage back to the Sectionalizer?

See attached E2.1.

3. E1.2 Note 4 calls for removal of pole mounted switch. The first note is on Pole 8-2-70 with the other one across the street. In its place E2.2 has an “S” in a square. E5.2 shows a 600A Switch in its place. Are we to install a pad mount switch at this location on E2.2?

Yes.

4. E3.4 at Bldg 624 area it shows lights on poles. Who is supplying pole and lights? If we do, please spec pole and light to be used.

The lights are existing new underground secondary is required.

5. E5.2 one line drawing is not the same as the plans indicate.

See new Sheet E5.2 attached.

THIRD LIST

1. Sheet E2.1, Note 7 - what is the location of this note? Demo sheet E1.1 shows removal of a transformer, but no replacement.

Note does not apply to E2.1

2. Sheet E2.2 - the new 10KVA xfmr near Bldg. 647 is not shown on the One Line on E5.2. Is the Sect. Switch shown north of AFFF TANK to be new? The pole mtd. switch previously at that location was shown to be removed on E1.2. Where the duct bank meets near Bldgs. 609 and 610 there is no Sect.Cab. shown, but one is shown on the riser - should there be a new cabinet?

The single line Diagram on Sheet E5.2 does not show a new 10 KVA transformer to be installed at building 647 but does show the sectionalizing cabinet. The transformer is needed. The padmount switch north of the AFFF tank is to be new.

3. Sheet E2.3 - at the NE end of the duct bank there is Sect. Cab. shown. The One Line on E5.2 does not show this - should that be an existing Switch as noted on the One Line?

See attached E2.3.

4. Sheet E2.4 - two new 10KVA xfmrs are shown, but not shown on the One Line E5.2.

The transformer shown south of building 621 alond Eielson Street is the source for lighting power along Eielson. Delete all work for the 10 Kva transformer North of Building 612. Only the existing padmount transformer at this location needs to be connected to the new work.

5. Sheet E2.5, Note 12 - says for the existing Switch to remain. On the One Line E5.2 it is shown as a new Cabinet.

The switch shown on E2.5 Note 12 is existing and remains. Sheet E5.2 does not show any difference between existing and new.

6. Sheet E2.6 - shows two new xfmrs, but the One Line on E5.2 only shows one.

The two transformers are required. See attached E5.2

7. Sheet E3.4 - in the NE corner of the drawing there are six unlabeled light fixtures. Are these new or just the rewiring of existing?

Lights are existing new underground secondary is needed.

8. Sheet E5.2 - bottom center of the page shows Circuit 8. Is there any work on Circuit 8 in this project (none is shown on any of the drawings, except for Note 10 reference to connect Switch 2 on E2.1) or is it just shown for reference?

Circuits 2 and 8 are on a common pole line that is to be removed. Both circuits need to be replaced by underground Power Cables. Circuit 8 is to feed loads west of building 621.
