13. Please identify all existing electrical infrastructure that must remain and provide revised demolition drawings identifying the electrical components to be removed, relocated, or protected. Location and notes regarding existing electrical infrastructure are accurate.

Existing transformer at current host site will remain.

14. Transformer-to-meter conductors, Host Site #1. E5.0 keyed note 3 calls for 3-#2/0 AWG Al direct burial with #1 ground from T-1 to meter M-1 (about 30 ft, E6.1 point X1), with no "by utility" note. Spec 262210 §2.1 says conductors from the transformer to the service entrance are "provided and installed by utility company." Who furnishes and installs this run? The transformer to meter connection is furnished and installed by the contractor.

15. Primary feeder and T-1 pad. E1.1 shows a "proposed underground M.V. feeder" from the south end to the new 50 kVA transformer. E5.0 marks the feeder and transformer "by utility." Please confirm Black Hills Energy provides all primary trenching, conduit, cable and the transformer pad, and the Government pays the utility per Spec 262210 §1.2.D. Is any primary conduit or pad work in the contractor's scope? Black Hills Energy has produced an estimated cost of $10,256.33 not including excise tax. Proposal is to cut in a new transformer into existing primary run. The existing primary conductor is in conduit

– contractor will be responsible for exposing area of conduit. Contractor will need to sweep one end of the conductor up into new transformer location and then replace the run north to the riser pole, approximately 350’. Contractor will need to supply fiberglass sweeps into new transformer base as well.

19. Contractor to provide and install secondary (service) conductors

20. Contractor to provide and install meter socket.

21. Contractor to provide service information (main panel size, size and number of secondary conductors)

22. Pumphouse service and meter. ED1.1 keynotes 2 and 4 say to protect and reuse the existing underground service to the pumphouse. E5.1 says to "install meter can, coordinate meter installation with utility company." Is the pumphouse metered today?

Yes. The pumphouse is metered today. Is the new meter socket mounted on the building or on a rack? The meter serves both the old host site and the pumphouse. The meter is mounted on a post immediately adjacent to the transformer.

23. Reuse of existing service conductors. Is the new pumphouse at the same location as the existing one? Yes

a. If it is moved, are splices in the existing direct-buried 2/0 Al allowed, and in what splice method and enclosure? Should we instead run new conductors from T-2 (E6.1 point X4, about 30 ft)? Reuse existing.

24. "Host site" in ED1.1 keynotes 2 and 4. These keynotes say the existing service is reused "with new pump house and host site." Host Site #1 gets a new transformer (T-1).

Do these keynotes mean the existing host site, which becomes Volunteer Site #7?

Yes. Reused with new pumphouse and converted host site (new volunteer site)

25. Site #7 metering and disconnect. E5.0 shows about 70 ft of 2/0 Al (point X5) from existing T-2 straight to the new Site #7 pedestal, with no meter or disconnect. Is Site #7 unmetered? Site #7 is metered.

26. Should the pedestal be service-entrance rated with a main breaker, or should a meter and disconnect be added as at Site #1? Site #1 is metered as per plan drawing sheet E5.0.

27. Site #7 pedestal: replace or reuse? ED1.1 keynote 5 says to "protect and reuse campsite pedestal with existing electric service." E1.1 says to "replace existing electrical pedestal with new pedestal." Which is correct? Replace Pedestal

28. Branch circuit to the control panel. The Panel L1 schedule (E6.0) shows the well pump control panel on a 20/2 breaker. E5.1 shows a 40 A disconnect inside the control panel and 2-#10 in 3/4". Please confirm the breaker and conductor size once pump data is known. The 40A disconnect switch is incorrectly shown as being in the control panel. The contractor shall install a separate, local safety disconnect switch within sight of or adjacent to the Well Pump Control Panel. The branch circuit to the Well Pump Control Panel (which includes the well pump load) should be a 25-amp double-pole breaker (which is standard for a 1 HP, 230V, single-phase submersible pump). The conductor size should be 2#10 AWG copper wire to account for the distance from the control panel to the pump (assuming 250-400 feet max) and to account for the inrush of the pump. Contractor shall inform the CO if the conductor developed length is greater than 400 feet so that the voltage drop can be evaluated and alternate conductor size can be selected.

29. Panel L1 interrupting rating. E5.0 and E6.0 call for a 14,000 AIC panelboard (available fault 11,142 A per E6.1). Spec 260500 §2.10.G requires "not less than 22,000 amperes RMS symmetrical." Which governs? Specifically, under Federal Acquisition Regulation (FAR) clause FAR 52.236-21 - Specifications and Drawings for Construction, if there is a difference or conflict between the drawings and the specifications, the specifications shall govern. Therefore, the panelboard would have a rating of 22kAIC (22,000 amps).

30. Storage tank level conductors. E1.1 says to "reuse existing feeders and tank level conductors" to the fiberglass tank. Item 0008 installs a new storage tank with new level sensors. Is the new tank at the existing location? The new tank will be set in the same location as the existing tank. If not, which bid item covers new level-control cable from the tank to the pumphouse, and what is the route length?

31. Pedestal configuration. Spec 260500 §2.14 names Midwest Electric U075CP6031 with 50/30/20 A outlets, a 20 A GFCI and TV/telephone. The drawings label it a "100A RV pedestal." No TV or telephone service exists on site. May the TV/telephone section be deleted, and will an equal pedestal from another manufacturer be accepted? The TV/Telephone may be deleted. An approved equal will be accepted.

32. DS-1 fusing vs. the pedestal. DS-1 is a 100 A disconnect fused at 50 A, feeding a pedestal with 50 A + 30 A + 20 A outlets. E5.0 general note 1 requires "full ampacity service rated breakers" for circuits protecting the pedestal. Please confirm 50 A fuses are intended or state the required fuse size. 50 A fuses are intended.

33. Vault alarm power and wiring. E5.0 keyed note 12 says "purchase extra breaker for sump tank alarm," implying power comes from a spare space in the RV pedestal. Please confirm the pedestal must have a spare breaker space for the alarm. Keyed note 11 also calls for 2-#12 Cu direct-burial cable to the alarm, while Spec 260500 §3.9.B requires the control cable "underground in conduit." Which method governs? A spare breaker will be required for the tank alarm. Either direct-burial cable or cable in conduit will be accepted.

34. Pull boxes. E5.2 Detail B shows a grade pull box, but E1.1 locates none. Are pull boxes required, and if so how many and where? Or are they installed only as needed for pulling? Installed only as needed for pulling.

35. PVC schedule. Spec 260500 §2.2.C and §3.3.B call for Schedule 80 PVC underground.

E5.2 Details C and D call for Schedule 40. Which governs? (For example: Schedule 40 for direct burial, Schedule 80 where exposed or under roads.) Schedule 80 is to be used. E5.2 details C and D are detailing trenches and exposed conduit.

36. Conduit vs. direct burial. Spec §3.4.A and E5.0 keyed notes 3, 4 and 11 call for direct-burial conductors. The E5.2 trench detail shows conductors in conduit. Please state which method applies to each run: T-1 to meter DIRECT BURIAL CABLE, ALUMINUM, 3-

#2/0 AWG WITH #1 GROUND FROM TRANSFORMER TO METER M-1

37. DS-1 to Site #1 DIRECT BURIAL CABLE, ALUMINUM, 3-#1 WITH #1 GROUND, T-2 to Site #7 DIRECT BURIAL CABLE, ALUMINUM, 3-#1 WITH #1 GROUND, and the vault alarm circuits DIRECT BURIAL CABLE, COPPER, 2-#12 WITH #12
