Ground investigation, foul & surface water, and foundation design services for a new 115,000ft2 distribution centre and 5,000ft2 office building.
Although the site was a green field site, it had an approximate fall of around 5m across it. The phase I report indicated that the underlying strata were likely to be variable so initially we undertook the investigation using trial pits to determine the competency of the soils, and recover sufficient soils for contamination testing and then followed this with a series of deep boreholes to determine the soil strength and other geotechnical properties.
PRP also designed the foul and surface water systems and designed the foundations for this scheme.
With the recovered soils from deeper depths we commissioned rigorous analysis and concluded that the soils could be compacted thus avoiding substantial construction costs associated with suspending the floor slab and supporting it on piles.
