About this file
This file is a Questions and Answers (Q&A) document for a Request for Information (RFI) related to the EMI Chamber B HVAC Replacement project (Solicitation Number W91ZLK-25-Q-0019). The Q&A document addresses multiple technical aspects of the HVAC replacement, including control systems, equipment specifications, and project scope. Key clarifications include confirmation that relative humidity should not exceed 60%, no bid bond is required, and Automated Logic BAS can be proposed if it meets specifications. The project involves replacing HVAC equipment, with specific notes that exhaust fans and motor-operated dampers are excluded from the contract. Manufacturers will need to provide technical specifications for proposed equipment, with flexibility in control system configuration and integration with the Building Automation System (BAS).
The solicitation is issued by the Department of the Army Materiel Command Army Contracting Command at Aberdeen Proving Ground. Vendors are advised that new equipment must be provided, and the proposed RTU (Roof Top Unit) should include detailed technical specifications. The Q&A document indicates that certain project details, such as airflow measuring stations, sequence of operations, and specific equipment features, will depend on the manufacturer's proposed equipment. Potential bidders are encouraged to carefully review the technical requirements and submit proposals that meet the specified performance parameters.

| C | Please confirm the need to monitor and control Humidity from the BAS. Specifically, around 4.2.10 on the SOW. | Relative Humidity (RH) is not to exceed 60%. It is understood/acceptable that during winter the RH will be less than 40%. The RTU is not required to increase the RH. |
| D | Can you please clarify what information is required to be provided in Factor 1: Technical? | The technical specifications of poposed equipment. |
| E | Is a bid bond required with our Price Volume? | No. |
| F | Is the RTU to come with Packaged controls or will these be field installed controls? | Depends on the equipment you specify in your proposal. |
| G | Can replace, in full, the existing control panel in lieu of replacing just the backplane and not the entire enclosure | I'm not certain what the 'backplane' is referencing. |
It is preferred to utilize the existing blue control panel.
| H | Sections 4.2.6 indicates a Schneider product while 4.2.5 indicates an open BacNet system. Can we bid Automated Logic BAS | Yes, providing it satisfies the specifications. |
| I | What items on the RTU, if any, are being furnished & shipped loose by the unit manufacturer | Depends on the equipment you specify in your proposal. |
| J | Are the (3) exhaust fans called in the sequence being replaced as part of the project as well, or if any of the MODs/Fans are to remain. | All of the exhaust fans & motor operated dampers are excluded from this contract. |
| K | Are the VFDs for the project to remain or will be provided as new. | The new equipment shall be new. |
| L | Will the unit manufacture for the RTU be providing the entire sequence of operations or if we need to provide this in the field. | Depends on the equipment you specify from the manufacturer. |
| M | Will the unit be provided with Airflow measuring stations from the manufacture. | Depends on the equipment you specify from the manufacturer. |
| N | Will exhaust fan 1 and vehicle Exhaust fan 1+2 be required to be placed on the BAS due to the way the sequence reads. | All of the exhaust fans & motor operated dampers are excluded from this contract. |
