This document contains responses to pre-proposal inquiries (PPIs) regarding the replacement of Air Handling Unit (AHU) #3 above Room 39 in Building 3030 at Naval Station Oceana. The Naval Facilities Engineering Command issued solicitation number N4008523R2780 for this project with a PPI cut-off date of July 21, 2023. PPI #1 requests as-built drawings showing the location and specifications of the electrical panel feeding AHU #2 and AHU #3, as well as the circuit breaker sizes. It notes the power to both units comes through the same feed. PPI #2 advises both units will be out of service at the same time during replacement of AHU #3, and the contractor must coordinate the outage with the building activity point of contact.

1 ETOLIN STRAIT ASSOCIATES 7.13.23
during the site visit we observed that the power feeding AHU 3 come thru a pitch pocket inside AHU 3 then feeds to a junction box which then connects to another junction box mounted on the outside of AHU 2 and feeds power to that unit. The B3030 user and the ET tried to locate the panel where the power feed is coming from for AHu's 2 and 3 but could not locate the panel. Please provide as-built drawings showing the location and mfg/capacity of the panel feeding these AHUs. We also need to know the breaker sizes for the circuit(s) feeding the AHUs.
As-builds drawings for this area are not available. Here is the info for the Power.
Motor Control Panel MCP-R Room – 34
AHU-2 CB11
AHU-3 CB12
2 ETOLIN STRAIT ASSOCIATES 7.13.23
The scope of work states to disconnect/reconnect the power from
AHU 3 so it can be removed and replaced. At the site visit it was observed that one feed is providing power to both as describe in PPI #1.
This is not a question but more of a notice that both units will be out of service at the same time for the same duration. Please advise if the govt has a different plan.
Contractor will have to coordinate with the
Building/Activity POC for this action.
