Questions and Answers (Q&A) Document

Question 1 (Q1): Hydrostatic Testing Schedule: Base Year CLIN 00010 requires hydrostatic testing for 216 cylinders, but this CLIN is missing from Option Years 1–4. Is all testing expected in the Base Year, or was a recurring hydrostatic testing CLIN omitted from the option years?

Answer 1 (A1): We had all the CO2 suppression cylinders in all 5 power houses Hydro tested in

2024. The CO2 portable/handheld fire extinguishers are mostly up to date and only a few at each facility are due. CO2 suppression cylinders need to be done every 10 years unless a release has occurred. Then the cylinder or cylinders included in that release, regardless of if it was accidental or intentional, must be hydro tested before it can be put back in service as an active or reserve cylinder. Large scale Hydro testing won’t happen again until calendar year 2034.

Q2: On-Call Services: Are the 20 cylinders listed under "On-Call Services" in the option years intended to cover ad-hoc hydrostatic testing and filling?

A2: Yes

Q3: Extinguisher Inventory: Can the Government provide an inventory list detailing the specific types and exact sizes of the approximately 250 portable fire extinguishers?

A3: No. Please see performance work statement (PWS) 5.3(b). There’s a clerical error and it’s listed as (a). The Government encourages attendance at the scheduled site-visit.

Q4: Valve Model Numbers: What are the manufacturer and model numbers (e.g., CV90, CV98) of the cylinder valves used at each of the five sites?

A4: CV90 and CV98 are used but the contractor’s responsibility ends at those valves. Our staff will disconnect and reconnect those valves when the contractor needs to fill or test the cylinders for the CO2 suppression system.

Q5: Cylinder Configuration: Are the 216 75-lb CO2 cylinders part of fixed manifold systems, or are any of them wheeled units? If wheeled, are there specialized scale requirements?

A5: NCAO no longer has any wheeled CO2 cylinders.

Q6: Fire Alarm Panels: Will Government personnel bypass the associated fire alarm panels during testing/inspections, or must the contractor provide a technician to do so?

A6: The Government will do the bypass.

Q7: Does the Government have spare cylinders on-site that the contractor can rotate in batches to keep the system active during hydrostatic testing?

A7: Yes, each system has a set of spares.

Q8: Off-Site Repairs: If a cylinder fails inspection and requires advanced repairs, is the contractor permitted to transport it off-site, provided the 4-business-day turnaround is met?

A8: Yes, the CO2 suppression cylinders have always been done off site. The portable fire extinguishers can be done either on site or off site.

Q9: Can the Government provide photographs of the CO2 systems and portable extinguishers to assist with technical planning?

A9: No. The Government encourages attendance at the scheduled site-visit.

Q10: Instead of collecting and servicing portable fire extinguishers and then returning the same unit once service is complete, is it acceptable to replace portable fire extinguishers with units of the same rating which have been serviced and hydro tested, ready for use? This will save time and ensure the government is never without a fire extinguisher in their required locations.

A10: Yes, that is acceptable as long as the replacements comply with ANSI 100 and CA codes and the fee is the same amount as the awarded purchase order unit price.

Q11: Could you please send me a picture of your CO₂ extinguishers as well as the portable ABC extinguishers?

A11: See PWS 5.3(a) CO2 System Locations for size of cylinders. See PWS 5.3(b) Portable Fire

Extinguisher Locations for size of portable fire extinguisher. There’s a clerical error with PWS

5.3 (b) and instead reflects 5.3(a). This will be corrected in the awarded purchase order.

Q12: What size are the CO2 cylinders (75lb or 100lb)?

A12: See PWS 5.3(a) CO2 System Locations

Q13: Do you want the cylinders pulled in batches and rotated with your spares to keep the system active during hydrostatic testing?

A13: Yes, we will pull them in batches. Our Mechanical staff will do the disconnect of active cylinders and swapping them with the spares after they are tested. All of the cylinders were hydro tested in 2024.
