Job #578: Harris County Pollution Control Services – Air Monitoring Specialty Vehicle Remodel

Project Overview

Clegg Industries successfully completed a comprehensive turnaround and structural retrofit of a mobile monitoring laboratory vehicle for Harris County Pollution Control Services. The project transformed an existing platform into a highly optimized, safe, and efficient mobile command and laboratory environment tailored for advanced air quality tracking.

Key Remodel Highlights

  • Structural & Exterior Upgrades: * Removed all existing side windows, structural retrofitting with continuous aluminum sheeting, and added vertical ribs on 16-inch centers to house upgraded insulation.

  • Replaced the rear emergency door and old windows with solid, insulated, sound-dampening panels built to withstand over-the-road travel.

  • Installed a custom bulkhead-isolated, exterior-access compressed gas cylinder cabinet capable of safely holding three A150 cylinders with interior-controlled stainless steel purge systems.

  • Power & Mechanical Systems:

  • Fabricated a custom, soundproofed rear generator compartment featuring a heavy-duty sliding service tray to house a high-capacity 12 kW diesel generator.

  • Integrated a 2,000 CFM dual-sided ventilation system and high-performance soundproofing to maintain main cabin noise levels well below 65 dBA.

  • Upgraded the shore power inlet and converted the entire vehicle electrical footprint from a 15-amp system to a fully compliant, robust 20-amp configuration.

  • Routed multiple dedicated delivery circuits to handle hardwired air conditioning, primary laboratory instrumentation, and dedicated UPS battery-backup systems.

  • Custom Interior Fabrication & Ergonomics:

  • Lined the cabin interior with durable plywood and finished with professional gray/black wall carpet.

  • Built a custom stainless steel workbench (300 lb. capacity) featuring integrated cable management, vibration-isolated under-desk laptop mounts, and dual VESA wall-mount monitor configurations.

  • Installed customized floor-to-ceiling cabinetry featuring heavy-duty drawer glides and secure positive-locking latches for transit.

  • Integrated space-saving overhead storage compartments in the over-cab area for crew personal gear.

  • Mission Safety & Equipment Integration:

  • Mounted a standardized 19-inch electronics equipment rack using specialized vibration isolators to protect critical analysis instruments.

  • Incorporated critical environmental safety systems, including digital continuous-read Oxygen and Carbon Monoxide sensors with configurable alarms.

  • Strategically installed recessed 1,000 lb. capacity tie-down points across the cargo floor and engineered custom rear storage bays to securely organize specialized field gear, including a 22-foot articulating ladder, infrared cameras, and an unmanned aerial vehicle (UAV) drone.
