FRC provided round-the-clock inspectors and
geologists to monitor excavations in the borrow
area for a runway safety improvements project at
Pittsburgh International Airport. The borrow area
contained soil; mine spoil; decomposed and
non-decomposed municipal waste; and residual and
hazardous industrial waste. A total of 750,000
cubic yards of soil, mine spoil, and decomposed
municipal waste was analyzed and qualified to meet
specific PADEP requirements and excavated and
placed in a ravine adjacent to a runway.
Approximately 125,000 cubic yards of
non-decomposed municipal waste was excavated and
consolidated in a lined, temporary stockpile. A
total of 1,200 cubic yards of industrial residual
and hazardous waste was consolidated in roll-off
boxes, tested, and properly disposed of. FRC
performed a subsurface investigation in one area
where a significant volume of waste remained. If
remediated under that contract, it would have cost
the owner $3.4M. FRC recommended that it be taken
out of the contract and rebid by itself. That
resulted in the area being remediated for $0.6M
instead, for a savings to the owner of $2.8M.
