Luzerne County, PA
This 175-acre reclaimed mining site in Wilkes-Barre was developed by Northpoint Development, LLC, based in Riverside, Missouri, and includes multiple warehouses totaling greater than 2,000,000 SF. Previously, the site was deep and shallow mined. It was reclaimed by a non-profit organization by backfilling with coal mine waste, soils, and rock.
GTA provided subsurface explorations, laboratory testing, geophysical (ERI and EM) surveys, and geotechnical evaluation, and construction observation and testing services for this redevelopment project. Subsurface operations included 32 test pits, 50 site wide SPT test borings, and several deep borings to confirm properties of the previous wash pond, and to evaluate underground mine subsidence potential. Due to the various conditions encountered on the site, GTA’s geotechnical recommendations included dynamic compaction (over 2 million SF) and shallow foundations, deep surface compaction, and slope reconstruction.
GTA provided full service construction observation and testing services including soil, concrete, and structural steel for the three warehouse buildings 808,160-SF, 842,880-SF 358,498-SF and site improvements including utilities, stormwater management, parking and drive areas. These buildings were constructed concurrently.
