PENNSYLVANIA CHEMICALS SHELL CRACKER PLANT PROJECT
Location: Pennsylvania, USA
Client: Fugro USA Land Inc
Installation Partner: Foundation Test Group
Constructed over 360 acres, Pennsylvania Chemicals, Shell Cracker Plant is one of the largest industrial construction projects in the USA. The plant will use ethane to produce 1.6 million tonnes of polyethylene per year.
The slope stabilizing work and the instrumentation was only done on the east side towards the palace (zone 1) and the south side facing the mosque (zone 2). To monitor performance before and after pressure grouting, rock bolting etc., instruments used included in-place inclinometers, piezometers, tiltmeters, beam sensors, borehole extensometer, temperature meters and an automatic data acquisition system.
The facility is built on the banks of the Ohio River in Potter Township, Beaver County, about 50 kilometres (30 miles) north-west of Pittsburgh. Several plant buildings were constructed on thick fill layers.
Rite Geosystems’ magnetic extensometers were installed to monitor the settlement under four buildings. The extensometers were installed in boreholes depths changing between 50 ft and 130 ft.
