Project Case Study
Naval Air Facility (NAF) -- Imperial, CA
Client: Western Pump, Inc.
Owner: US Navy -- NAVFAC EXWC
Subcontractor: Westcon Construction Services, Inc.
Project Overview
Westcon Construction was selected by Western Pump to deliver structural concrete upgrades and modifications at the Naval Air Facility (NAF) in Imperial, CA. This work supported Defense Logistics Agency (DLA) fueling system upgrades under NAVFAC EXWC oversight.
The project required specialized structural concrete work for fueling facilities, containment systems, and safety infrastructure, ensuring durability, compliance, and mission readiness for a critical U.S. Navy installation.
Scope of Work
Westcon's subcontract covered the complete structural concrete package including:
- Curb & Gutter Replacement -- Matching existing site standards.
- Patch-Back Paving -- Restoration at oil dispenser areas.
- Structural Foundations & Bases --
- Headwalls
- EFSO station footings
- 24" and 18" diameter pipe support bases - Safety Bollards -- Installation of 26 concrete-filled protective bollards.
- Concrete Utility Placement Pads -- 8" PCC sections for utilities, 4'x4' pump pads.
- Containment Systems --
- CIP Containment Basin
- CIP Refueler Truck Containment Pad
The scope also required compliance with prevailing wage laws, NAVFAC technical specifications, and all federal and environmental regulations.
Key Challenges & Solutions
1. Federal Standards & Compliance
All work had to meet strict NAVFAC and DLA design standards. Westcon implemented enhanced QA/QC protocols and provided submittals for approval before mobilization.
2. Operational Sensitivity
The project took place on an active Naval Air Facility, requiring strict security coordination, sequencing to avoid operational impacts, and adherence to Navy safety requirements.
3. Specialty Concrete & Safety Features
Containment basins and refueler truck containment pads required jet fuel-resistant waterstop, precision doweling, and strict slope tolerances (minimum 1% grade for drainage per special conditions).
Results & Impact
- Delivered structural concrete improvements to mission-critical fueling facilities.\
- Enhanced fuel handling safety with reinforced containment pads and protective bollards.\
- Ensured compliance with Navy, federal, and environmental standards.\
- Supported the Navy's operational readiness with durable infrastructure upgrades.
Conclusion
The NAF Imperial project highlights Westcon's ability to perform high-security, specialized structural concrete work for federal clients. By meeting stringent NAVFAC standards and collaborating closely with Western Pump, Westcon successfully delivered infrastructure that improves safety, compliance, and reliability for U.S. Navy fueling operations.
