FEN was awarded the decontamination work of a large manufacturing plant, which consists of 1.3 million square feet under roof. Completion time of the project is three (3) months, utilizing multiple crews and a fleet of equipment.

The building had previously been used in the manufacturing of steel parts and, as a result, the site was blanketed in oil.

All floor surfaces, basements, tunnels, trenches, underground piping, underground tanks, above ground tanks, required cleaning by removal of standing oils, greases, industrial sludges, and manufacturing-related oil-soaked debris and by-product (example: grinding swarf (mixture of coolant and metal fines)).

In addition, many sections of the building contained an extensive network of shovel – wide 24” deep trenches (utilized to catch by product from machines that previously existed) that contain standing oils and oil soaked debris.

Also required is decontamination and cleaning of the onsite wastewater treatment system.

The majority of the cleaning work is performed via 10,000-20,000 PSI hydro blasting pumps, hot water and steam cleaning units, and via industrial vacuuming (trucks). Other equipment also utilized: Floor sweepers, bobcats, forklifts, jet – rodding trucks, and pipeline inspection equipment.

Multiple crews work simultaneously, six (6) days weekly for three (3) months.
