IV. THE FOLLOWING QUESTIONS AND ANSWERS / CLARIFICATIONS ARE THE RESULT OF BIDDERS REQUEST(S) FOR INFORMATION:

Q1. The 8” LPS to the heat exchanger connects to an existing unsized line off of the new 6” portion described above. Should the new 6 inch portion be 8”? Is the existing branch serving the new HTX-5C-01 the correct size?

A1. See Section III for changes made on project drawings.

Q2. Please provide existing pipe sizes on M300 where we are new piping is connecting.

A2. The three branch connections to the new 10” line will be; 2” (AHU-145a SV bypass), 3” (AHU-145a SV), and 2” (AHU-122 humidifier).

Q3. Are CAD as-built drawings available for coordination of new?

A3. Yes Q4. Heat exchanger detail on 1/M502 shows a steam control station. M300 shows new steam control valves SCV-5C-01 and SCV-5C-02 which appear to be installed in an existing 1/3 2/3 steam control valve station which would serve the new Heat Exchanger HTX-5C-01. Are the shut off valves, strainers, blowdowns, pressure gauge associated with HTX-5C-01 existing to remain?

A4. SCV-5C-01/02 on M300 identify location of the steam control station for HTX-5C-01 as detailed on 1/M502. All shut off valves, strainers, blowdowns, pressure gauge, ect. associated with HTX-5C-01 per the detail are to be installed new with the installation of new HTX-5C-01.

Q5. Is an end of line main steam drip trap required at heat exchanger HTX-5C-01?

A5. No, unless required by the manufacturer.

Q6. Spec Section 23 22 13 2.2C calls for galvanized steam vent pipe. Some of the vent pipe is over 2” so assume it needs to be welded. What is the procedure for welding galvanized pipe, or are all of the fitting to be flanged?

A6. Steam vent piping (i.e. Safety valve piping) shall not be galvanized. Use materials for steam piping per section 23 22 13.

Q7. On plan page S105 there is a note #9 and no corresponding note in the key. What does note #9 mean?

A7. There is no Note 9 on S105. Note 9 as indicated should read Note 8 and reference as such.

Q8. What is the current fire alarm panel, make, and model?

A8. Simplex 4100 ES Q9. Is there a fire alarm contractor for the facility? If so please provide contact information.

A9. Yes. Johnson Controls; Simplex. Direct any questions specific to the facility fire alarm system to the VA.

Q10. Is this project tax-exempt?

Q12. Are we to carry the cost for the commissioning agent or is the agent hired by the Gov't?

A12. Per specification 230923, 1.1.E.3 General Contractor to directly hire the Control System Integrator in a contract separate from the contract procuring the controls contractor administered by 230923.

Q13. Is all work on the floors to be done after hours or just the demo? There is a note on the demo drawings "TP-2" mentioning after-hours work however the note does not carry to the rest of the drawings.

A13. “TP-2” on the demolition drawings refers to the “General Infection Control Requirements” Note 2 on dwg. GI002. This note does not exclude the possibility of after-hours install work needing to be done due to the necessity of maintaining hospital/system operations. It is not the intent of this Note to require all work to be done after-hours. Demolition/construction on floors B through 4 will be after hours.

Q14. We are assuming, Note TP-2, for after-hours work is that meant to apply for the entire floor. Is that correct?

A14. “TP-2” on the demolition drawings refers to the “General Infection Control Requirements” Note 2 on dwg. GI002. This note as referenced pertains to necessary demolition on the drawing space.

Q15. Pressurized Expansion Tank Schedule on M700 – expansion tank size is missing from the schedule.

A15. Pressurized Expansion Tank Schedule on M700 – expansion tank size is missing from the schedule.

ANSWER: Size tank based on 800 gallons, 50F to 180F, vertical with bladder, approx 24” diameter x 5’ with 80 gallon tank volume, per attached schedule update.

Q16. Steam Pressure Reducing Valve Schedule on M700. The valves for each station are described with a 1/3 – 2/3 set-up, however the steam capacity is listed as the same amount of 7,016 pph for each valve. Is 7,016 pph the total steam capacity of the entire station, therefore the 1/3 valves and 2/3 valves should be sized for 2,339 pph and 4,677 pph respectively? Or, is the total capacity of the station 14,032 pph, and the valves are actually setup as ½ - ½?

A16. See Section III for changes made to M700.

Q17. Please provide locations of lead-based paint remediation.

A17. No LBP remediation is required Q18. Please confirm if DIV 25 13 00 BAS integration contractor needs to be a separate contract from the DIV 23 09 23 Direct Digital Control System. Can each contractor be carried with the mechanicals, or does the GC need to hire the DIV 25 13 00 BAS integrator?

Q20. Will prime contractor have access to all rooms / areas per phase for the entire duration?

A20. Yes. Times and phasing need to be coordinated with the VA.

Q21. Are we to assume any mobilizations per phase, or will building be unoccupied to perform the work in one continuous mobilization per each? Is Phase 1 to start and finish prior to Phase 2 starting, and same for all phases following?

A21. Building/floor will not be unoccupied during entire phase. Local affected area(s) may be unoccupied during affected phases. Per the “Suggested Phasing Notes and Sequence” contractor to coordinate a phasing plan with the VA prior to work, as well as between each contractor and sub-contractor. Phasing does not imply the completion of one phase prior to the start of a subsequent phase provided a plan to overlap can be reasonably coordinated.

Q22. If prime contractor does not have access to each phase’s rooms at once, please confirm the amount of rooms per each mobilization GC should expect to have for each work.

A22. See Q20.

Q23. In all rooms that have existing furniture, will the VA be providing the labor to remove prior to construction in these areas and then re-install following construction?

A23. No. Contractor shall be responsible for any necessary removal of equipment/furniture needed to perform work, and the subsequent reinstallation of equipment/furniture upon completion of work as necessary.

Q24. If prime contractor is to remove / relocate equipment in rooms, what location is the prime contractor to assume removal to for each phase?

A24. Contractor to coordinate with the VA for relocation/disposal of any removed equipment.

Q25. Please confirm who is proprietary to the system for DIV 23 09 23 Controls Specifications.

Pressure Driven Condensate Pump Traps; this project should not contain any equipment referenced in this section. 23 22 13 3.2 Welding H. Non-Destructive Examination of Piping Welds (page 30) does fully pertain to this project and shall be followed.

Q29. Section 23 31 00 part 3.1-H specifies to clean new and existing ductwork. How much existing ductwork needs to be cleaned?

A29. See Section II for language added to 23 31 00 Q30. Does the contractor need to hire a 3rd party fire penetration inspector as specified in Section 07 84 00 part 1.5-C?
