1. Question: Spec raceway and boxes 260533 3.1 A Outdoors: 1 & 2 are asking for ENT type conduit . Spec raceway and boxes 260533 3.1 B Indoors: 1, 2 & 3 are asking for ENT type conduit . Drawings E101, E201, E202, ES101 & ES102 notes state: All wiring shall be run in PVC conduit . Please confirm which conduit to use, the two conduits are different Articles within the code . If ENT conduit remains please provide a spec and or part number, the NEC is very vague on this type of conduit.

Response: All wiring shall be run in PVC Conduit.

2. Question: Comparing / Reviewing drawings E001 thru ES102 with PM-1 thru PM-5 there seems to be info missing (conduit/control wiring/power for controls) from the electrical drawings to make this a complete operational system. Drawing PM-1 well #7 plan view shows a 6” flow meter located in the middle of the room. Also pressure switch panel detail shows a H/O/A switch panel located in the electric room with control wiring between the two .(who provided the H/O/A switch). Same for Well #18

Response: The contractor is to provide the HOA. Wiring diagrams for the HOA and pressure switches are shown on drawing E302. This drawing includes calling out all wiring to be installed in conduit.

3. Question: Drawing PM-1 Coburn Treatment BLDG shows three flow meters and the pressure switch panel detail as well.

Response: Add note to drawing E101 Power Plan for Coburn Water Treatment Building: Provide 120V power from circuit RPC-9 to Chemical Chart recorder install pulse output cable from each flow meter in conduit. Location of Chart recorder and flow meters are shown on drawing PM-3.

4. Question: Drawing ES102 Duck Drive Pumps please provide control wiring and will each one need a rack to support the disconnects.

Response: These are actually the grinder pumps and they are specified with a complete control package. Mount control panel and disconnects independent of tank. Provide 2” galvanized steel posts with caps encased to 30 inches below grade. Extend between the two posts the necessary galvanized steel conduit required to mount equipment. All hardware to be stainless steel.

5. Question: Reference drawings A101, A102, and A103, the Floor Plans call for a fold down attic access ladder in the Coburn Water Treatment Building, the ESA Well No. 7 Building, and the ESA Well No. 18 Building. There are currently no specifications on these ladders, please provide any required specifications.

Response: Each ladder is to be a Werner AH2512 - 25”W x 66” L x 12’ H Ceiling Aluminum Attic Ladder (see attached cut sheet). See revised Drawings A101, A102 and A103 (revision #3 dated 3-4-15) that show the revised location of the attic ladders. Also see new Attic Plan Drawing A106 (revision #3 dated 3-4-15) which shows the revised location of the attic ladders as well as additional plywood sheathing in the attic space.

6. Question: Reference: Drawing CN-02, Drawing C-1 thru C-9 and detail 2 on drawing C-22: Detail 2 on drawing C-22 is not part of this contract. Therefore, the total number of hydrants on this project should be 37, which includes 28 blow off yard hydrants and 9 replacement yard hydrants. However, Drawing CN-02 Materials list for ESA lists 324 yard hydrants. Please clarify the correct amount of yard hydrants.

Response: The correct number of yard hydrants is (37) and the correct number of Curb stop w/ Curb box is (0). See the attached revised drawing CN-02 (Revision #3 dated 3-4-2015)

7. Question: Reference detail sheet number C-22. The Water Cup and Drain is crossed out. However, almost every other sheet -1 thru Sheet 8 requires us to Retrofit Existing Water Cup See Detail C-22. So I’m afraid not to price the 289 Water Cups that have LOD marked around them, yet I don’t want to price something that’s not included.

Response: The Water Cups and Drain Detail as shown on C-22 have been deleted from this project.

Revisions:

1. Change: Drawing SW-1- The Title of Detail #2 “Recycle Pump and Treatment System” To Read: “Recycle Pump and Treatment System Typical of (9)”

2. Add: On Drawing ES102 add a dedicated 1P-120V circuit to each one of the (9) 1500 watt heaters in the fiberglass enclosure as shown on detail #2 on drawing SW-1from Panel DDP. Panel DDP on E202 shall be double width.
