Chase Environmental Group,
Inc. was responsible for the turn-key removal of approximately
6,000 square feet of flaking paint in the air return plenum
of a defense remanufacturing facility in Indianapolis.
Chase prepared the work
plan, and prosecuted the work during back shift hours so
that there would not be a disruption of factory operations.
The work was performed in the plenum approximately 16 feet
above the factory floor.
Chase installed fall protection
rigging and a solid floor, a ceiling access portal, a complete
negative air containment, a 200 amp temporary electrical
service, and job lighting in preparation for the paint and
rust removal. The containment entailed operating articulating
lifts in very close proximity to closely spaced and sophisticated
computer controlled milling equipment on the factory floor.
Once the containment was
erected and certified, Chase used dry ice blasting and hand
scraping to remove loose rust and paint. Following the paint
removal, Chase prepared the surfaces for painting using
detergent wipes. All surfaces were then primed and painted.
All loose debris was retrieved and the top surface of the
ceiling tiles were vacuumed using HEPA equipped vacuum cleaners.
All wastes were bagged and shipped to a facility permitted
to receive PCB contaminated materials.
The entire project, including
a change order that increased the scope of the project by
20 percent, was performed 3 weeks ahead of the schedule
promised for the base bid.
