This investigation was commissioned to allow our client to assess the potential this former inert landfill has for residential development and was undertaken to gain both geotechnical and geoenvironmental data.
The work comprised of:
- Five cable percussion boreholes.
- Two machine excavated trial pits.
- Three TRL DCP probes.
- Insitu geotechnical and geoenvironmental testing and sampling.
- The installation of seventeen combined gas and groundwater monitoring standpipes.
- Subsequent groundwater and ground gas over two months.
- A suite of geotechnical laboratory analysis.
- A suite of chemical laboratory analysis.
- Production of an interpretative report.
The site investigation fieldwork took place over the period 27th August to the 13th September 2019, ground gas monitoring is ongoing.
five boreholes to 20.00 mbgl, along with two machine-dug trial pits to 2.50 mbgl, in order to gain an understanding of the strata beneath the site with respect to foundation design. TRL DCP probes were also performed to test the strength of the ground closer to the surface, in preparation for the car park’s lower level.
The site investigation fieldwork was completed on schedule, and with the current car park in operation throughout the works.
