STATEMENT OF WORK (SOW)

EOD Nuclear Response Trailer

5 CES/CED Explosive Ordnance Disposal

Minot Air Force Base, North Dakota

Date: 21 September 2026

1.0 INTRODUCTION & MISSION CONTEXT

1.1 Scope of Requirement

The 5th Civil Engineer Squadron Explosive Ordnance Disposal (5 CES/CED) Flight requires one (1) custom-manufactured, weather-resilient, self-sustaining mobile operations and life-support trailer. This specialized vehicle will serve as a continuous, on-scene command and sustainment hub for Initial Response Force (IRF) and Response Task Force (RTF) teams during multi-day, full-spectrum nuclear accident or incident response operations.

1.2 Operational Environment

The trailer must operate reliably in the extreme environmental conditions characteristic of the northern and central North Dakota plains, including sub-zero winter temperatures down to -40°F, high winds up to 25 mph sustained, and heavy snow accumulations. EOD response operations frequently take place at remote Missile Alert Facilities (MAFs) and Launch Facilities (LFs) across the Minot Air Force Base Missile Complex, requiring up to two (2) hours of transit time each way over unimproved, washboard, or snow-covered gravel roads. Due to the critical nature of these operations and the projected 24-hour arrival timeline for external Department of Energy (DOE) support assets, the trailer must support continuous, independent field operations for a six-person EOD team for extended durations (+24 hours) without external utility connections.

2.0 CONTRACTOR ACQUISITION TASKS

2.1 Task 1: Engineering Design, Technical Approval, and

Production

2.1.1 Engineering and Fabrication: The Contractor must perform all necessary engineering, structural design, material procurement, fabrication, and quality control assembly to produce one (1) new EOD Nuclear Response Trailer meeting the technical performance requirements outlined in this Statement of Work.

2.1.2 3D CAD Submittal (Deliverable A001): Prior to initiating physical fabrication, the Contractor must deliver complete 360-degree, three-dimensional Computer-Aided Design (CAD) drawings and comprehensive system schematics (including structural, plumbing, HVAC, and electrical layouts) to the Government for review and formal approval.

2.1.3 Requirements Coordination: The Contractor must coordinate closely with the 5 CES/CED requirements team throughout the engineering phase to address and resolve design questions.

2.1.4 Design Review Authority: The Government's review of the design drawings is for compliance validation only and does not authorize or constitute a vehicle for unilateral scope changes. If the Government requires more than ten

(10) business days to complete its review, a day-for-day schedule extension will be bilaterally applied to the delivery timeline.

2.2 Task 2: Transportation and Delivery

2.2.1 Delivery Destination (Deliverable A002): The Contractor must transport and deliver the completed, fully assembled trailer to the 5 CES/CED EOD facility (Building 897, Minot Air Force Base, ND 58705).

2.2.2 Delivery Hours: The Contractor must schedule delivery during normal business hours: 0830 to 1530 Central Time, Monday through Friday, excluding federal holidays.

2.2.3 Base Access & Security Protocol: All Contractor delivery and setup personnel must comply with Minot Air Force Base security checkpoint requirements. This includes complying with the REAL ID Act of 2005 for identity verification and passing standard commercial vehicle gate inspections. The Government will provide entry routing information prior to delivery from the Commercial Vehicle Gate to Building 897.

2.3 Task 3: Technical Manual Requirements (Deliverable

A003)

2.3.1 Documentation Scope: The Contractor must provide comprehensive operator, maintenance, and system documentation covering all onboard mechanical, electrical, plumbing, and life-support systems for the EOD mobile facility/trailer.

2.3.2 Electronic Manuals: The Contractor must deliver complete electronic copies (searchable PDF format or Government-approved equivalent) of the operator and maintenance manuals concurrently with, or prior to, the physical delivery of the trailer.

Liability: Government review is strictly for compliance validation and does not relieve the Contractor of liability for structural or system performance.

8.1.3 Final Acceptance Inspection (Deliverable A002): The Government will inspect and accept the completed trailer at Minot AFB, ND, based upon a Contractor-furnished Certificate of Conformance (CoC) confirming full compliance with SOW specifications.

8.1.4 Latent Defects Protection: In accordance with RFO 52.212-4(o), acceptance of the CoC does not waive the Government’s right to seek non-cost repair, replacement, or equitable price reduction under latent defect provisions should thermal or HVAC systems fail to maintain outcome thresholds (+68°F heating at -40°F cold; +74°F cooling at 100°F heat) during field operations. The Contractor's warranty obligations must comply with RFO 52.212-4(o).

8.1.5 Testing Methodology: Physical "cold room" environmental chamber testing is excluded to mitigate commercial overhead. Thermal compliance must be proven via static engineering calculations and heat load modeling during design submittals.
