W50S9H-24-Q-0001
HVAC UNITS WITH REMOVAL & INSTALLATION
QUESTIONS & ANSWERS
Q1. Is there a Lead / Lag controller currently in use to operate the existing Bard HVAC units? If no, would a Lead / Lag Controller for the Bard HVAC units be desirable?. The lead / Lag controller will alternate the operation of the two Bard HVAC units at a preset schedule interval, (e.g. every 7 days) to maintain both Bard HVAC units fully operational with 100% redundancy.
A1. There is already a lead/lag controller installed on the system. The Bard units are connected to preconfigured control panels inside the equipment shelter that provide lead/lag functions and override capabilities.
Q2. Would a Bard Heat Pump be considered in place of the Bard AC unit for this procurement. The Bard Heat Pump is the same size and dimensions as the Bard AC unit, with the exception that the heat pump would be the primary heating and cooling engine and the 9 KW electric heat kit would provide auxiliary heating?
A2. The model number identified is the one required by the DASR program office. Please reference solicitation Brand Name Justification document.
Q3. Current delivery time for Bard HVAC units is 12 weeks. Can the period of performance be extended accordingly?
A3. The Delivery Date for the requirement will be adjusted based on the date the contract is awarded.
Q4. Only the basic model number was provided. Will the Army require any additional options with the 4 HVAC units? Such as low ambient cooling, economizer sections, pressure sensors, filtration, etc.?
A4. 5-ton capacity air conditioner w/ 9KW electric heater, R410A refrigerant – no additional options are required.
Q5. The SOW states that this project is the removal and replacement of four (4) ECUs in a Digital Airport Surveillance Radar (DASR) shelter. The project involves removing two units of model Bard WA602-C09EXXXXV and two units of model Bard WL602-C09EXXXXV and replacing them with four (4) units of model Bard WA60AC- C09ZPXXXV.
In the Requirements section it states to provide four (4) new Bard WA602-C09EXXXXV. Can you please clarify which ones are needed for the project?
A5. The required units are W60AC-C09ZPXXXV.
