Replacement of Chemical Process Tanks

Description and Location of Work:

This in-house design-build project required the replacement of approximately 40 large (24’ x 4’ x 10’) chemical process tanks weighing up to 12,000 lbs, steel tank support structure, and support equipment in an existing Air Force electro plating facility. Work included removing and replacing six existing plating process lines, steel structure, PVC ventilation hoods and PVC ductwork, ventilation system, scrubbers, electrical, and plumbing systems. The new ventilation system was designed and installed by HHI’s own crew exceeding EPA, OSHA, and American Conference of Government Industrial Hygienists (ACGIH) requirements. The new system included new PVC fume hoods at 34 locations that ventilated to four mesh pad scrubbers. Controllable dampers, water softening system for automatic wash down, and automatic drain systems were also designed and installed by HHI. All testing was completed by HHI and confirmed by government bioenvironmental personnel. The work was accomplished while the owner continued to occupy and utilize the facility. The owner occupancy required close coordination & multiple temporary bypasses to keep the plating facility operational. HHI’s engineering staff designed the new structural steel support structure for the tanks and integrated the design of the new tanks and new ventilation system within the existing building. The work completed by HHI’s 29 CFR 1910.120 HAZWOPER certified crew included engineering, design, demolition, fabrication, and installation.
