MWD HVAC Questions

1. The PWS states that the Contractor shall ensure the terrain can support the HVAC equipment and that “building up terrain is required to ensure a level surface.”

Please clarify the extent of site work the Government anticipates. Specifically, is the Contractor required to provide aggregate base, grading, compaction, concrete pads, or other permanent site improvements, or is only temporary leveling and stabilization necessary for placement of the leased HVAC units, generators, and auxiliary fuel tanks?

Government Answer: The Government anticipates that all contractors submit their proposal to build up existing terrain where necessary and provide all materials and labor. Contractors shall provide aggregate base, level and grade, compact to ensure stabilization for safety and to protect rental equipment. The ground leveling by the contractor will be a temporary leveling that will need to be removed upon completion of the contract. No permanent fixtures are authorized. Please refer to pictures as the ground has steep inclined slopes.

2. The PWS requires the Contractor to enclose the kennel roof gables using exterior-rated duct board.

Please clarify whether the existing kennel structures provide adequate attachment points for the required gable enclosure, or whether the Contractor is responsible for furnishing and installing temporary framing or structural supports necessary to support the exterior-rated duct board and associated ductwork.

If framing is required, please provide any applicable material, attachment, structural, or restoration requirements.

Government Answer: The contractor is responsible for all temporary framing and structural supports. Framing wood material is acceptable and can be anchored to existing kennel framing. Temporary ties are permitted. All framing and duct board will be removed at the end of the service. Please refer to the Site Visit Pictures attachment to see all ground levels and sloping present.

3. The PWS requires the Contractor to provide all generator fuel and continuous refueling services throughout the base period and potential option period.

Given the potential for significant and unforeseeable increases in diesel fuel prices resulting from geopolitical events, supply disruptions, emergencies, regulatory changes, or other extraordinary market conditions beyond the Contractor’s control, will the Government provide any consideration or price-adjustment mechanism for significant increases in diesel fuel costs during the period of performance, or is the Contractor expected to assume all fuel-price escalation risk under this Firm-Fixed- Price contract?

Government Answer: No, this is a Firm-Fixed-Price (FFP) contract. Accordingly, the Contractor is expected to assume the risk of standard market fluctuations, inflation, and typical geopolitical impacts on fuel pricing during the 1-year base period and 1-year option period. Offerors should utilize online databases regarding fuel changes and past fuel costs to pre-plan and account for potential price escalations within their submitted quotes.

4. At the completion of the incumbent contractor's performance, will all temporary leveling materials, gravel, sandbags, pads, and other equipment-support materials currently associated with the installed HVAC and generator equipment be removed by the incumbent contractor, or may the incoming contractor utilize existing leveling materials remaining onsite?

Government Answer: The incumbent contractor is scheduled to remove and restore area as necessary. The awardee will work with the incumbent to ensure a proper transition. During this phase both parties will work together the transition. See question number one for reference.

Government Answer: Yes

8. May the white plastic tubing be moved/installed higher toward the center of the sloped roof so it isn’t directly above the dogs?

9. Can you provide any historical data on fuel usage?

Government Answer: The government estimates roughly that 120,000 gallons of fuel are used per year. However it’s recommended that the contractor calculate fuel consumption based on the contractor’s specific approach. Contractors should consider size; manufacturers make and model of generator they plan to use to meet this requirement. Consider various factors again, generator size, fuel tank capacity, and full load that will cover gallons per hour during operation.

10. Can you provide any historical data on JBSA winter freeze information? How long does it freeze, how has this affected the HVAC/generators in the past? In the pass year there were only 4 days below freezing and lasted 12 hours each day.

Government Answer: There was no effect on HVAC units or Generators incumbent contractor was on site monitoring equipment ensuring temperature was maintained as per PWS.

11. During the site survey we saw 12 HVAC units with 12 generators total. The PWS asks for only 6 generators. Are you sure 6 generators is enough?

Government Answer: PWS and solicitation have been changed to reflect 12 generators.

12. Are the kennels 40 x 150 or 50 x 150? The PWS currently states 40 width, but at the site visit it was stated verbally they are approx. 50 feet in width.
