Introduction
CORE was awarded a remediation contract by Lovell Homes, for a large new residential development site at Lakeside near Doncaster. The enabling works included re-engineering the road corridor, installation of a capping layer to the proposed road, earthworks cut & fill, formation of a piling platform and installation of piling mats.
The site remediation and earthworks package included:
- Topsoil strip
- Excavation of made ground beneath the road footprints to a depth of around 1.5m and removal of a band of peat which varied in depth from 300mm to 1m, engineer the made ground back into the road footprint to form the road sub formation.
- Re-grading of the site and laying stone pile mats (for the plots) together with haul roads
- Installation of the compound for Lovell with associated works
- Testing carried out to satisfaction of Doncaster MBC
- Total volume of peat excavated and disposed off site circa 6,400m3
- The highways authority would not accept the peat below the road corridor, therefore the peat overburden was removed. The overburden was subsequently re-engineered back in place as part of a site-wide cut and fill, bringing the road corridor to underside of capping layer.
The peat was taken from site to a licensed landfill due to its chemical composition. CORE’s scope also included cut and fill to the remainder of the site to form development plateaus.
