PROJECT HIGHLIGHTS
– Excavated / backfilled seven test pits and two areas of pre-clearing for a total of ~1,300 cubic yards.
– Installed, than extracted, seven pairs of 50- and 60-foot steel sheetpiles for a total of 2,251 square feet.
– Placed more than 100 tons of stone rip-rap to stabilize the embankment.
– Placed and finished 625 square feet of concrete within an active concrete plant.
– Utilized an odor suppressant foam and spray during excavation activities and on stockpiles, and disposed of MGP-contaminated soils at an owner-approved facility.
– Provided vibration, air, dust and noise monitoring. – Installed environmental controls including silt fence and oil /
silt boom. – Demolished bulkhead and other concrete structures, and sized

CUSTOM SOLUTIONS
– When a high-powered vacuum truck could not clean out all of the soil in the sheet enclosures, Cashman collected the soil during sheet driving,
– Cashman designed a custom airlift powerful enough to get 50 feet deep, yet small enough to fit in the 3-inch gap in the enclosure.
