15 September 2026

1. What will be your primary mover of this trailer?

Answer: Primary mover would be a Ford F-450, although this is dependent on the type of trailer/weight of trailer we receive.

2. Are there any sketches or drawings of your design idea?

Answer: There aren’t sketches, but the SOW accurately reflects the ideal layout.

Reference: 8.1.2 Design Approval of SOW

3. Do I have the liberty to change generator sizing and defined amperages of shore power and electrical panels?

Answer: Loads not defined will be limited to powering lights, charging computers, powering the TV display, and utilizing the on-board appliances.

Reference: SOW 5.2

a. The a/c and heat unit take up most of the 100-amp desired panel space in your defined environments and I don’t know what your electrical loads will be outside of the defined items related to trailer.

4. It does state gooseneck coupler which I believe to have a maximum weight rating of 30,000#s, and I am having some real concerns that my product built to these specifications could exceed that rating. Is this a hard requirement.

Answer: ** See #1. The gooseneck seems to be the most appropriate option for us. If there are other suitable options, we can look into them and see if they are viable. Reference SOW 3.3

a. Relates back to prime mover of the trailer above.

5. Safety Shower: The specification is asking for emergency shower and separate drain. I know the emergency shower requires 20gpm and a 15-minute time which would require 300 gallons of water.

Answer: Shower does not need to meet emergency shower requirements. Reference

SOW 6.3.7

6. Interior zone dimensional allocation: the SOW identifies approximately 12 ft for Zone 1, approximately 22 ft for Zone 2, and a minimum 14 ft clear garage for Zone 4, totaling approximately 48 ft before allocating separate space for the Zone 3 full bathroom/decontamination package, while total trailer length is limited to 46-50

ft. Please confirm whether the stated zone lengths are approximate design targets that may be adjusted during the approved CAD design phase, provided all required functions and the minimum 14 ft clear garage are maintained.

Answer: The dimensional lengths for the zones provided in the SOW are approximate design targets. The critical requirement is maintaining the minimum 14-foot clear garage space in Zone 4. Offerors may propose adjustments to the other zone lengths during the CAD design phase (SOW Section 2.1.2) to meet all functional requirements within the overall 46 to 50-foot trailer length. Reference

SOW 6.0

7. Curbside awning requirement: the exterior C2 workstation language calls for a motorized commercial awning with a minimum 15 ft length, while the tactical lighting section calls for one 25 ft motorized exterior power awning on the curbside. Please confirm whether a single 25 ft awning meeting with the integrated lighting requirement satisfies both provisions.

Answer: A single, 25-foot motorized exterior power awning on the curbside that features an integrated LED light strip will satisfy both the SOW Section 7.5.4 (Scene Lighting & Shelter) and Section 7.6.3 (Awning Lighting) requirements.

8. Nonmanufacturer Rule: FAR 52.219-33 is incorporated by reference. Please confirm whether the Nonmanufacturer Rule applies to this acquisition and whether an SBA waiver has been obtained. If it applies and no waiver exists, please confirm that the offered end item must be manufactured in the United States by a qualifying small business manufacturer.

Answer: In accordance with RFO FAR 19.104-3(e)(1), RFO FAR 52.219-33, and 13 CFR 121.406, the Nonmanufacturer Rule does apply to this acquisition. The requirement is set aside for small businesses, has been assigned a manufacturing NAICS code, and exceeds the Simplified Acquisition Threshold (SAT). No class or individual SBA waiver exists for this procurement. Therefore, in accordance with RFO 52.219-33(c)(1), any offeror that is not the manufacturer of the offered trailer must supply the product of a small domestic manufacturer or processor, or the quote will be deemed non-compliant and ineligible for award.

9. Wage determination / service labor: Please confirm whether any wage determination, prevailing wage requirement, certified payroll requirement, or other labor-rate requirement applies to delivery, setup, operator and maintenance training, or other on-site work under this acquisition.

Answer: This acquisition is primarily for a commercial commodity. Delivery, standard setup, and commercial orientation/training are incidental to the supply item (FAR Part 12 / 29 CFR 4.117). However, standard on-site Contractor escort and base pass requirements apply. No certified payroll or Davis-Bacon / DBA requirements apply. If Service Contract Labor Standards (SCLS/SCA) apply to incidental training labor, prevailing local wage determinations will govern.

10. Functional zones: Section 6 states the interior must be partitioned into three distinct functional zones, while Sections 6.1 through 6.4 identify four areas, including a separate bathroom/decontamination area and rear tactical garage.

Section 8.1.2 also refers to all three partitioned zones. Please confirm the intended number and arrangement of partitioned functional zones.

Answer: The trailer comprises four (4) distinct functional spaces, typically divided into three primary physical structural compartments: Reference SOW 6.0

• Zone 1: Front Habitation & Wet Zone

• Zone 2: Zone 2: Mid-Ship Command & Culinary Zone

• Zone 3: Zone 3: Full Bathroom Package & Decontamination Routing

• Zone 4: Zone 4: Rear Tactical Garage & Auxiliary Living Zone

11. Past Performance Information Form: Page 19 of the solicitation states that an attached Past Performance Information Form (PPIF) may be used, but the attachment list identifies only Attachments 1 through 4 and no PPIF was posted.

Please provide the PPIF or confirm that past performance information may be submitted in the contractor’s own format.

Answer: Will do an Amendment PPIF will be Attachment 5.

12. Product literature and photographs: Because the required trailer is a custom-manufactured one-off configuration, please confirm whether representative photographs of similar completed builds, component literature, and a technical compliance/design narrative are acceptable to satisfy the product literature and clear photograph requirement at quotation stage.

Answer: Representative photographs of similar custom builds the offeror has previously completed. Product literature (cut sheets) for all major Original Equipment Manufacturer (OEM) components to be used (e.g., generator, HVAC system, axles, etc.). A detailed technical narrative that cross-references the proposed design and components directly to the requirements in the Statement of Work (SOW) to demonstrate how the proposed trailer will meet all specifications.

This package will be used to determine technical acceptability in accordance with the evaluation factors outlined in the solicitation. Reference SOW 2.0

13. CLIN 0003 pricing: The solicitation identifies CLIN 0003 Operator & Maintenance Training as “Not Separately Priced,” while Attachment 4 contains a price field for On-Site Training & Manuals. Should the Quote Sheet show $0.00 for CLIN 0003 with the training cost included in CLIN 0001, or should a separate amount be entered on Attachment 4?

Answer: CLIN 0003 is Not Separately Priced (NSP) The cost for operator and maintenance training, manuals, and warranty support must be integrated into the unit price of CLIN 0001. If Attachment 4 contains a separate line for training, enter "$0.00 / NSP" so that total price evaluation aligns directly with CLIN 0001.

14. DD Form 254 / security clearance applicability: Attachment 2, Section 4 states that the contract includes a DD Form 254, but a DD Form 254 is not included in the posted attachment list. Please confirm whether a DD Form 254 applies. If it does, please provide it and identify any facility or personnel clearance requirements. If it does not, please confirm that no DD Form 254-related clearance requirement applies to performance.

Answer: A DD Form 254 is not required. The reference to DD Form 254 in Attachment 2 was an administrative template artifact. All work on Minot AFB will be performed in unclassified areas under standard visitor/escort protocols.

15. Building number for on-base work: The SOW identifies the 5 CES/CED EOD facility as Building 897 for delivery and training, while Attachment 2, Contractor Access, references work in Building 555. Please confirm the correct building/location for delivery, training, and any other contractor work requiring base access.

Answer: Building 897 is the correct control facility for all physical delivery, inspection, and on-site training (5 CES/CED EOD Facility). The reference to Building 555 is if a long-term base pass is required, this contract shouldn’t require long-term base pass.

16. Trailer dimensions and layout: Does the 46–50-foot length include the gooseneck? The approximate habitation, command, and garage lengths total 48 feet. Where should the bathroom fit within those dimensions, and is a preliminary floor plan available?

Answer: The dimensional lengths for the zones provided in the SOW are approximate design targets. The critical requirement is maintaining the minimum 14-foot clear garage space in Zone 4. Offerors may propose adjustments to the other zone lengths during the CAD design phase (SOW Section 2.1.2) to meet all functional requirements within the overall 46 to 50-foot trailer length. The Contractor must submit complete 3D Computer-Aided Design (CAD) drawings and layouts for Government review and approval prior to the start of fabrication.

(Deliverable A001). Reference SOW 8.1.2. The 46–50-foot length is not including the gooseneck. Reference SOW 6.0

17. HVAC configuration: Section 4.3.3 permits a 36,000-BTU mini-split or equivalent rooftop system, while Section 4.3.7 requires three 15,000-BTU rooftop units.

Which requirement governs? May we propose an engineered heating solution to achieve the required 68°F interior temperature at −40°F ambient?

Answer: The government permits and encourages bidders to propose custom-engineered heating and thermal management solutions. While the SOW baseline outlines specific equipment configurations, alternative systems are fully acceptable provided they are accompanied by verified engineering calculations, thermal modeling, or manufacturer performance data demonstrating the system's capability to maintain an internal temperature of 68F at an extreme exterior ambient temperature of -40F (ND Winter Heating Target). Reference SOW 4.3.3

18. Air filtration: Section 6.3.6 is titled “Positive Pressure Prep” but calls for an installed HEPA/CBRN system. Please confirm whether a complete operating system is required and identify the required filtration standard, airflow, positive-pressure target, and acceptance criteria.

Answer: The Habitation (Zone 1) and Command & Control (Zone 2) areas must be protected by a permanently installed, self-contained CBRN filtration and positive pressure system designed to prevent the ingress of airborne radiological, chemical, and biological contaminants.

6.3.6.1 System Components: The system must consist of a high-static-pressure blower, sealed filter housing, dedicated intake/exhaust ports, and a combination filter cartridge.

6.3.6.2 Filtration Performance: The filter cartridge must be a combination HEPA/activated carbon type, providing a minimum filtration efficiency of 99.97% for airborne particulates of 0.3 microns in diameter and incorporating a carbon bed for gas-phase contaminant absorption.

6.3.6.3 Positive Pressure Performance: The system must deliver a minimum of 120 CFM of filtered air to the sealed crew zones. When active, it must generate and maintain a continuous internal positive pressure of +0.20 inches W.C. (water column) above the external atmospheric pressure.

6.3.6.4 System Control & Power: The system must be controlled by a dedicated switch on the main interior control panel and wired to a mission-critical circuit that is never shed by the Energy Management System (EMS).

6.3.6.5 Acceptance Testing: As a key performance parameter, the system's ability to achieve and hold the specified positive pressure must be demonstrated and verified with a digital manometer during final acceptance at the delivery location.

19. Weight and vehicle loading: Please confirm the required payload capacity and any maximum GVWR or loaded gooseneck weight. What towing vehicle will be used, and what are the dimensions and loaded weight of the UTV or other largest equipment to be transported?

Answer: The SOW has been amended in Section 3.3.1 to establish definitive weight and vehicle loading parameters:

• Maximum GVWR: The trailer's fully loaded Gross Vehicle Weight Rating (GVWR) shall not exceed 30,000 lbs. under any operational configuration (including all fluids, maximum rated equipment, and cargo payload).

• Towing Vehicle & Interface: The primary towing vehicle is a Government-Furnished Ford F-450. The trailer must utilize a heavy-duty, adjustable height 2-5/16-inch gooseneck coupler compatible with a standard bed-mounted hitch.

• Gooseneck Pin Weight: The loaded pin weight on the gooseneck coupler shall not exceed 6,000 lbs. (20% of the maximum 30,000 lbs. GVWR) to protect the F-450 rear axle rating (GAWR).

• Largest Equipment (UTV): The trailer's rear tactical garage is engineered to transport an EOD-configured UTV weighing up to 3,500 lbs. fully loaded wet weight (e.g., Polaris MRZR or equivalent) and heavy EOD robotic platforms (e.g., L3Harris T7, weighing up to 710 lbs.).

• Mandatory: In accordance with SOW Section 3.1.1.1, the contractor must submit a Finite Element Analysis (FEA) or certified structural engineering report prior to frame fabrication to mathematically verify frame deflection remains within the skin adhesive manufacturer’s allowable tolerances under a full 30,000 lbs. load.

20. Exterior material: Section 3.1.3 specifies minimum .040-inch screwless blue fiberglass sheets. Please confirm the intended material and thickness, and whether aluminum or composite exterior panels are acceptable alternatives.

Answer: The exterior skin must be screwless, weather tight, and finished in Ultramarine (Air Force) Blue Sheets. To ensure structural integrity in extreme, cold environments, the Government will accept either of the following options:

• Composite Panel: Minimum 3mm-4 mm thickness, screwless bonded commercial-grade panels.

• Aluminum Composite Material (ACM): Exterior: Heavy-duty metal, minimum .050, screwless bonded.

• All proposed materials must be engineered to withstand extreme thermal expansion/contraction from -40 F to +100 F without buckling, cracking, or delaminating from the trailer framework. Standard fiberglass/FRP panels are not acceptable due to cold-weather brittleness and impact risks at sub-zero temperatures. Reference SOW 3.1.3

21. Slide-out and awning: Please confirm the required extension depth of the 244-inch slide-out. May one 25-foot powered awning satisfy both awning requirements, and are separate awnings required?

Answer: A single 25-foot motorized power awning with an integrated LED light strip will satisfy both awning requirements. Reference SOW 7.5.4 and 7.6.3

22. Electrical operation: With the specified 50A shore connection and 20 kW generator, is load management permitted? Which systems must operate simultaneously, and what generator runtime must be demonstrated using the specified 60-gallon fuel capacity?

Answer: The generator system and dedicated 60-gallon fuel supply must demonstrate a minimum of 24 continuous operational hours without refueling under a simulated steady-state mission profile averaging 70% rated continuous load (14 kW) in ambient temperatures down to -40 F. Load Priority Hierarchy: The Contractor shall configure the electrical distribution sub-panels and the EMS logic to adhere to the following load-shedding priority levels:

• Priority 1 (Life/Mission Critical – NEVER SHED): Command center workstations, communications/radio systems, mission equipment charging outlets, positive-pressure CBRN air filtration system, primary HVAC blowers, and interior operational/emergency lighting.

• Priority 2 (Operational Comfort – STAGED SHED): Secondary HVAC heating elements/compressors, main cabin wall outlets, and vehicle battery bank charging systems.

• Priority 3 (Auxiliary/Discretionary – FIRST TO SHED): Electric water heater element, galley appliances (including microwave), and exterior scene/perimeter lighting.

Reference SOW 5.2.6.4

23. Training: Section 2.3 requires training at Minot AFB concurrently with delivery, while the deliverables table references training at the contractor’s facility within 15 days after delivery. Please confirm the required location and timing.

Answer: The SOW has been amended in Section 2.3.1 and Section 8.2 (Deliverable A003) to establish a single, consistent training requirement:

• Training Location: All hands-on system orientation and operational training shall be conducted on-site at the Minot AFB EOD Facility in North Dakota. Training at the contractor’s facility is not acceptable.

• Training Timeline: The training shall be executed within fifteen (15) calendar days following the final physical delivery and initial Government inspection of the trailer.

This provides the Government with a brief window to complete receiving inspections before formal training begins.

• Manuals: Electronic operator and maintenance manuals must be delivered concurrently with the physical trailer, with finalized physical manuals provided at the start of the training course.
