Contract Opportunity

*Update 5 Feb 2025 - This update provides the questions received along with the Government's response. This update also adds an attachment of site photos that show the locations of the existing units. Note: This requirement does not include installation. The Government will be performing the installation.

Question 1: Location 15400 Air Force Rd Brandywine, MD for delivery.

Can they specify where pick up is (Loudon or Capitol Office) is this a town? They also mention “Vertiv”. When we search those terms for dealers and towns it is not populating anything.

There are Vertiv dealers, however not in those two towns mentioned

Government Response: 15400 Air Force Rd Brandywine, MD is where the HVACs need to be delivered.

The Loudon and Capital Offices are two names for the local Vertiv offices which is located in Loudon County, specifically in Ashburn, VA.

Question 2:

Can you provide some details or photos of the existing site conditions? One important thing is site access, how the units will be moved throughout the facility, and where they are currently located. Also, are the units on a computer-raised floor?

Government Response: The Existing site conditions are good the old units are still installed and operational, the units will need to be offloaded preferably by the transporter, and we can then move the units with pallet jacks at the facility once they are offloaded from the Truck. The units are not on a computer raised floor, to access the site please contact 89CS/HVAC at (301)981-6129 SSgt McClelland or Tommy Jones can be reached and provide access to site, upon arrival we will need at least a 30min advanced notice to allow for commute time to site. Please see the new attachment with pictures of the existing Liebert units (Liebert PDX Air Cooled System Site Photos).

Question 3: Is this project for BOTH Purchase and Install of the equipment or just Purchase and delivery of the equipment and you will install yourself ?

Government Response: This requirement is to purchase and deliver the equipment. The Government will complete the installation.

Question 4: Is this to furnish and install (and remove old units) or will we simply be furnishing these for installation by others? It appears that we are to deliver only according to the delivery location paragraph on the document titled combined synopsis and solicitation December 2024.

Government Response: This requirement does not include installation or removal of the existing units. The Salient Characteristics specifies that this is to purchase and deliver the units.

Question 5

The SOW mentions the need for two (2) 5-ton heat pumps and two (2) 6.5-ton Liebert units. Could you confirm if the two heat pumps are indeed required? Additionally, would it be possible to obtain pictures of the equipment’s tags (model and serial numbers) for both the condenser and the air handling unit?

Clarification:

1. Is the intent to replace two computer room units along with their condensers rather than heat pumps?

2. If so, would a 6-ton condenser be acceptable for this application? These units are typically matched 1:1 with their corresponding evaporator.

Understanding this distinction will help ensure we are proposing the correct equipment. I appreciate your time and look forward to your clarification.

Government Response: The 5-ton heat pumps have already been installed, we would be installing (2) 6.5-ton Liebert units (2) Indoor and (2) condensers. The intents is to replace the two existing Liebert units with (2) new 6.5-ton Liebert PDX units with matching condensers.

Question 6:

If awarded the contract should a rep from my firm be on site to deliver the materials to you?

Government Response: Yes, we would need a rep to be onsite to offload the materials as we do not have the capabilities to offload.

All work must be completed IAW the Salient Characteristics (Attachment 1).
