Deadlines-SoON Federal Opportunities: HVAC repairs (site visit), USACE surveying events, DLA sources sought, and last-call RFQs

Executive takeaway

Several of these notices are effectively “act now or stand down” due to very near (or already elapsed) response deadlines. The most actionable, scope-defined requirement in this batch is the US Coast Guard Desert Air system repair (compressor skid and heating coil/heating element replacement) because it spells out removals/replacements and explicitly requires a site visit before bidding. The USACE Caribbean District items are engagement opportunities (industry/outreach events) that can shape an upcoming IDIQ for surveying and mapping. The DLA item is a sources sought—use it to get on the radar if you can manufacture/supply the specified NSN/part number.

What the buyer is trying to do

USCG: Restore a specialized outdoor-air HVAC “Desert Air” unit for UPH

The Coast Guard needs to remove and replace compressors and heating coils/elements on a specialized HVAC unit that controls humidity and conditions outdoor air to protect facilities/equipment and improve indoor air quality. The notice emphasizes refrigerant recovery, removal of existing components, and installation of new compatible replacements—with field verification via a required site visit before bids.

USACE Caribbean District: Line up A-E surveying/mapping capacity for future civil works tasking

USACE is signaling an upcoming A-E effort for topographic and hydrographic surveying and mapping services supporting planning, design, construction, and O&M across Puerto Rico and the Antilles (and, in a separate outreach notice, Puerto Rico and the U.S. Virgin Islands). These notices are positioned as market research/outreach (not awards).

DLA Land: Identify sources for a specific howitzer mount NSN

DLA is seeking sources capable of providing NSN 1015-01-705-7922 (Mount, Howitzer), part number 13067705, with an estimated quantity and delivery window stated. This is informational and not a solicitation.

Other “deadline-now” items: MAS and a USCG sliding chassis

Two “Multiple Award Schedule” notices are listed without descriptions, and a USCG “Sliding Chassis for Cooler” appears with a same-day deadline and no snippet detail. These may be administrative postings or require immediate attachment review to determine suitability.

Who should bid / who should pass (bullets)

Bid if…

• You are an HVAC mechanical contractor with demonstrable experience on specialized outdoor-air/humidity control units and can handle refrigerant recovery and component change-outs (USCG Desert Air).
• You can attend and support a required site visit quickly and turn around a compliant RFQ response immediately afterward (USCG Desert Air).
• You are an A-E surveying/mapping firm (or a prime with surveying subs) operating in Puerto Rico/USVI/Antilles and want to shape/track an upcoming USACE IDIQ pipeline.
• You are an OEM/qualified manufacturer or authorized supplier for NSN 1015-01-705-7922 / part number 13067705 and can engage DLA’s source approval process.

Pass if…

• You cannot schedule the required field verification/site visit before pricing the Desert Air repair scope (risk of noncompliance and mis-quoting).
• You are not positioned to work in the Caribbean geography referenced by USACE, or you lack survey/hydrographic capability and would be starting from zero.
• You cannot support defense supply chain expectations for the DLA item (traceability/qualification) and have no path to source approval.
• The notice shows a deadline that is already in the past (several in this batch) and you cannot confirm an amendment or reposting in the attachments/portal.

Pricing & strategy notes (how to research pricing; do not invent pricing numbers)

USCG Desert Air repairs

• Use the site visit to lock down quantities and compatibility (the notice explicitly requires field verification before bids). Your pricing accuracy will hinge on what you confirm in the field.
• Build your estimate around the major cost drivers implied by the notice: refrigerant recovery, removal/disposal logistics, compressor skid procurement, heating coil/element procurement, and labor to swap components and return the unit to service (verify performance/acceptance requirements in the SOW).
• Research comparable federal HVAC repair awards by searching historical postings using the solicitation number 31040RFQ260000158 and related PSC/NAICS in your internal price library (if available), then sanity-check against current component lead times.

USACE surveying/mapping IDIQ positioning

• Because these are outreach/industry-day style notices, focus less on price and more on how you will present capacity (crew depth, equipment, and ability to surge across Puerto Rico/USVI/Antilles) tied to the listed survey types.
• Track the anticipated IDIQ shape described (one-year base with options; maximum order limit mentioned) and use it to decide whether you want to be a prime, a specialist sub, or both (confirm details in the full notice text/attachments).

DLA sources sought (NSN/part)

• Do not “price” a sources sought response unless asked; instead, emphasize qualification, traceability, and your pathway through the source approval program referenced in the notice.

Subcontracting / teaming ideas (bullets)

• Desert Air repairs: Pair an HVAC prime with a specialist supplier for compatible compressor skids/heating elements if you do not stock/procure these routinely; ensure the prime can still control refrigerant recovery and on-site work.
• USACE surveying/mapping: Team a surveying prime with niche subs for inland hydrographic surveying and/or geodetic control—especially if you want to show breadth across the full list of work types.
• DLA howitzer mount: If you are not already approved, consider teaming with an authorized/qualified manufacturer or distributor who can support the source approval pathway referenced.

Risks & watch-outs (bullets)

• Several response deadlines in this dataset appear already elapsed relative to the posted date (or are same-day). Treat these as “verify immediately” and check for amendments, time zone differences, or reposts in attachments/portals.
• Desert Air repairs: Site visit is stated as required. Missing it (or failing to document field verification) can make your quote nonresponsive or inaccurate.
• Desert Air repairs: The notice uses both “heating coils” and “heating elements” language—confirm exactly what the unit has and what is to be replaced during field verification and in the SOW.
• USACE events: These are not awards; do not over-invest in proposal writing. Use them to position for the future IDIQ and to clarify acquisition strategy.
• DLA sources sought: This is not a solicitation. Overpromising delivery/capability without a realistic source approval path can backfire.
• Water well drilling: The snippet is high-level; confirm scope, location specifics, and all performance requirements in the Statement of Work before deciding bid/no-bid.

How to act on this

1. Pick one: (a) USCG Desert Air repair RFQ, (b) USACE Caribbean surveying/mapping pipeline, or (c) DLA howitzer mount sources sought.
2. Open the attachments and verify deadlines and submission instructions—several notices in this set show deadlines that may already have passed.
3. If pursuing Desert Air: schedule/complete the required site visit immediately and document field verification for your quote.
4. If pursuing USACE: register for the outreach/industry engagement and prepare a tight capability narrative tied to the listed survey types and geography.
5. If pursuing DLA: submit a capabilities response aligned to the NSN/part number and the referenced source approval pathway.
