A ground investigation was undertaken for Mistral Energy in connection with extension of the Burton Wold Wind Farm at Burton Latimer, near Kettering in Northamptonshire. The project comprised the construction of seven turbines with access routes for construction and maintenance traffic, an electricity sub-station and a temporary construction compound.
A desk study was carried out, which indicated that the majority of the site was underlain by glacial drift deposits overlying a succession of Middle Jurassic age limestone, sandstone and mudstone. Part of the north end of the site was shown to be covered by infilled ground and also coincided with an area of historical quarrying and mining for iron. One of the turbines was planned to be located in this area.
The site investigation comprised the drilling of eight light-cable percussion boreholes, eight machine excavated trial pits, four rotary cored boreholes, four seismic dilatometer tests and six cone penetration tests. The investigation provided information for the foundation design of the turbines and the sub-station.
