Bam Nuttall’s geotechnical contractor Bam Ritchies has completed ground investigations for the Hampstead Ponds scheme in north London.
The contractor drilled 140 exploratory holes at the site, ranging from 3m to 15m in depth. A lightweight modular pontoon was used to carry out overwater boreholes on the model boating pond (pictured).
The results of the ground investigation will be used by the client the City of London Corporation to design the £15M Hampstead Heath Ponds flood prevention dams project.
There are about 30 ponds on the heath, most of which are formed by dams up to 300 years old that are currently at risk of failing in severe weather.
