In solicitation page 9.

2. Steam Traps. Note in the Contract Documents: all the Steam Trap Wireless Trap Monitoring is (was) provided under separate contract; so that all data associated with the steam traps is to be OMITTED from the current set of plans and specs. So, all work shown on Dwgs. EP121-127 is “N/A” for this boiler replacement project, correct? Which means all the steam traps as identified on Dwg. M001, and steam trap locations shown on Mechanical Dwgs. M100-M111 are N/A as well? Now new steam traps are to be supplied under this project?

All Monitoring for the steam traps is to be omitted (I.E. EP121-127, and M100-M111). However, any steam traps that are noted in any of the other drawings and specs to be replaced in the energy center, will be replaced and existing monitoring will be reconnected.

3. Can you confirm that the Steam Trap monitoring scope of work is deleted from this project in its entirety (Sheets M001, M100, M101, M102, M103, M104, M105, M106, M107, M108, M109, M110, M11)?

Correct, (Also see above)

4. The specification calls for C/B EX- Elite boiler, this is a two-pass boiler, does the VA allows two pass boilers. Does the VA allow 4-pass wet backs. Please confirm?

A 4-pass wet back is allowed by the VA; however, the physical dimensions were found to cause too much interference with existing high voltage conduits and main communication lines in this boiler plant which cannot be moved. Therefore, 2-pass was chosen as basis of design and is allowed by the VA.

a. Does the VA allow “rifle” type tube (spiral)?

No

b. Does VA allow for alternative brand of boiler?

As mentioned above the boiler used as basis of design is preferable, however alternate boilers may be used if they meet specifications, salient characteristics, are approved by the EOR, and the contractor makes the necessary adjustments to other trades and systems for proper construction coordination with his boiler of choice.

5. What is the VA’s rates for utilities – power and natural gas?

For power it is .05298 cents per KWH. For Gas it is .27 cents per therm.

The Specification documents of the RFP, section 1.16 indicates that we are responsible for paying the VA for all metered electrical power and fuel usage. Also, section 1.14 states “proper” temporary and mechanical installation for temporary equipment. Please provide applicable rates for cost purposes.

6. Please confirm if Contractor needs to provide boiler room operators and chemical treatment workers for temporary equipment.

Although no temp boilers are planned to be used, the contractor would be responsible for temp boiler operations and maintenance while in use.

7. Are there post tension cables in concrete between floors?

NO

8. The plans indicate location of temporary tie in for steam and gas lines, can you provide size and location of these lines?

Refer to sheet MP202 note #5 and sheet MP401 note #1

9. Do the boiler plant system controls need to be integrated into the Bay Pines campus existing Metasys Control System as provided by Johnson Controls corporate branch office?

No, the VA does not allow the boilers to be connected to Metasys. The boiler plant system controls must be stand alone.

10. Is BIM modeling required?

REVITT models are not required for shop drawings.

11. What are the limitations for use of pile driving equipment for the structural new piling required?

See addendum #1

a. Existing plumbing lines may obstruct location of new piling, can piles be offset to clear underground obstructions?

Yes. Please coordinate with structural Engineer of Record to determine best locations once any existing pipe obstructions are known.

12. MCC Electrical work may require shut-down, is there a temporary tie-in location to provide emporary power?

Yes.

1. Does the VA retain Scrap Material?

No, all scrap metal will be recycled in accordance with Specification 01 74 19, Construction Waste Management.

1. If so, will there be a designated place to take scrap material?

See above.

Please provide a ductile iron pile specification and geotechnical report. The pile manufacturer requests this information for them to evaluate driving conditions.

See Addendum #1

In speaking with the pile manufacturer, the Sheet S205, detail 8 indicates a rebar cage that most likely is not achievable. They recommend either one center rebar with grout, or just grout. Please advise.

The pile manufacturer also indicates the need for overhead clearance of about 25 feet in order to install the piles. Please advise if the plant has this clearance.

See Addendum #1 Addition notification:

Spec section 01 00 00 Section 1.6, para L-2 says: “Contractor shall submit a request to interrupt any such services to COR, in writing, 7 days in advance of proposed interruption. Request shall state reason, date, exact time of, and approximate duration of such interruption.”

This should read: “Contractor shall submit a request to interrupt any such services to COR, in writing, 14 days in advance of proposed interruption. Request shall state reason, date, exact time of, and approximate duration of such interruption.”

Spec section 01 00 00 Section 1.6, para L-4 states:” Major interruptions of any system must be requested, in writing, at least 15 calendar days prior to the desired time and shall be performed as directed by the COR.”

This should read: “Major interruptions of any system must be requested, in writing, at least 21 calendar days prior to the desired time and shall be performed as directed by the COR.”

Spec section 01 35 26, sect. 1.17, para D-2.b states: “or overhead protection with a design live load of 300 psf is provided.” This is deleted from the current specs.
