VIASANT has recently completed initial site remediation activities at the country’s most notable/prestigious fine porcelain manufacturing facilities. The scope of work included the excavation and offsite disposal of over 8,000 tons of TPH and liquid asphalt impacted soils form two (2) separate source areas on this multi-acre manufacturing complex. To allow access to part of the source material, a former boiler building was demolished prior to the start of excavation. VIASANT managed the ACM survey and abatement of the structure prior to demolition.
The source removal work required the complete underpinning of two active manufacturing facilities. To ensure stability of the foundation VIASANT installed over fifty (50) helical piles to a depth of 15 feet bgs using angle iron bracketing on the entire foundation due to its deteriorated condition.
All excavation work occurred within the groundwater table (GW is at 1.5 to 3 ft) requiring continual water management and waste material handling/drying for excavations ranging from 4 to 6 feet bgs.
VIASANT avoided well point dewatering and costly large volume water disposal by performing all excavation services in the “wet”. VIASANT excavated each AOC in smaller sections of 200-300 cubic yards and backfilled to the GW table daily with QP stone. Post-Excavation bottom surveying was accomplished by utilizing a modified settling plate system with PVC tubes to full depth allowing accurate readings even after backfilling to final grade. A high strength geotextile layer was installed between the QP and DGA to limit material lose and settlement during compaction. Final restoration of the site included a 1 acre 6” asphalt cap. Work at the site will continue in the spring of 2010 pending wetlands delineation work.
