Questions Received from Industry

The following questions and answers are provided for clarification.

1. Reference: Specification Section 22 00 00 page 16 Para 2.1.6

Question: Provide acid-resistant DWV pipe, fittings, and couplings of the mechanical, bell & spigot, or fusion type joints. Material for buried piping and aboveground piping shall be ASTM A 518M, silicon-iron composition. (Can below grade and above grade acid resistant piping be plastic fusion weld – such as by Enfield, Orion, or George Fisher?)

Response: Provide as specified.

2. Reference: Specification Section 22 00 00 page 16 Para 2.1.6

Question: ASTM C 1053, borosilicate glass pipe and fitting to be provided for aboveground piping, except vent piping through and above roofs shall be silicon-iron composition. (Is above ground piping to be borosilicate glass or silicon-iron as stated in sentence before or can it be plastic fusion type?) Provide cleanouts and drains as specified for DWV piping, except material shall be silicon-iron composition. This section is not clear as to what is to be priced and provided.

Response: All above ground piping is to be borosilicate glass, except last four foot section of vent through the roof piping which shall be silicon-iron composition piping.

Cleanouts and drains are to be provided and installed per Part 2 (DWV Piping) of Section

22 00 00, except piping material shall be silicon-iron composition.

3. Reference: Mechanical dwgs

Question: I see boilers B-3 and B-4. Are there a total of two boilers on the upgrade? (gas and No. 2 oil, 150#, 5 sq. ft. , 30-PPM).

Response: One boiler shall be installed in this contract, B-4.

4. Reference: Drawing Sheet M05.01

Question: I am trying to verify the gas pressure to the main fuel train and pilot. I see a gas train schematic on drawing M05.01, but I may be missing the gas pressure.

Response: Gas pressure within Power Plant feeding existing boilers is 10.5 psi.

5. Reference: Mechanical dwgs

Question: What is the steam operating pressure?

Response: Steam operating pressure is 862 kPa, per Phase 9A and 9B - M04.02.

6. Reference: Specifications

Response: Deaerator and associated pumps have been installed in a prior contract and will be reused. Refer to Attachment "B".

7. Reference: Boiler Specifications

Question: I do not know if you are in communication with the consulting engineer, but they have referenced 3 Mil specs that have been obsolete for years (MIL-B-18897, MIL-B-17452, Mil-B-18796). I would normally say take exception to these Mil specs.

Response: Delete reference to "MIL-B-18897F" and replaced with "Federal Specification F-B-

2910". Delete reference to "MIL-B-17452" and replaced with "Federal Specification F- B-2903". Delete reference to "Mil-B-18796" and replaced with "Federal Specification F- B-2910".

8. Reference: Boiler Specifications

Question: Your service group should review Part 3 (Execution) of the boiler spec. There are tests that someone will have to run after the start-up is completed. I see an ASME PTC.4 short form efficiency test. I do not know your group is capable of conducting this testing, or whether the contractor will handle that part.

Response: All tests within Part 3 are to be provided by the contractor.

9. Reference: General

Question: Is it acceptable to submit a “Teaming Agreement” in lieu of a Joint Venture Agreement for two firms submitting the proposal together?

Response: A teaming agreement is acceptable.

24. Reference: Re-Roofing

Question: Clarify the extent of re-roofing required under this option. From keyed Demolition Notes #9 and 18 on Drawing A00.06, it does not appear that the entire roof area between Column Lines 1 and 11 is to be re-roofed. This is contrary to the total re-roof indicated on Dwg. A01.06. Likewise, we do not locate Keyed Note #18 on Drawing A01.06.

Response: Option #1: Re-roofing extends between Col. Line#1 thru Col. Line#11. In demolition dwg. A00.06, note #9 & #18 defines the existing roofing to be removed and in dwg.

Response: Refer to Dwg. A04.01, keyed Note #17 and see Attic elevation portion on both North and

South Elevation showing symbol with 17.

26. Reference: Re-Pointing

Question: Clarify that ALL work designated within the dashed line indicated as Option 1 on Drawing A01.06 is to be priced in the Roofing Option, and not in the Base Bid.

Response: Correct
