The Ground Investigation (GI) carried out by our geo-environmental engineers at Kingswood Parks provided detailed information to enable the redesign of flood defences and mitigation measures for a major residential development on the northern outskirts of Hull. The GI was planned in conjunction with other WYG services at the site including drainage and flood defence.
Kingswood is a proposed urban community consisting of a residential development for up to 18,000 people, employment and shopping facilities, a new primary school and a health centre. Its proximity to the River Hull defined the site as a high-risk flood zone requiring new flood defences, flood-proof building design and the integration of sustainable urban drainage systems (SUDS) into the masterplan.
We undertook extensive ground investigation along the existing flood embankment to provide information for flood mitigation design. The GI comprised Cone Penetarion Testing (CPT), window sampling and cable percussion boreholes.
The nature of the site presented significant access challenges which were exacerbated by inclement weather. To overcome this, WYG utilised a versatile track/truck CPT unit in conjunction with a lightweight window sampling rig to minimise damage to the embankment
We also installed gas and groundwater monitoring installations complete with water monitoring divers from which data was downloaded over a twelve-month post-fieldwork period. This data was then collated in our factual report with associated AGS 4 data.
Due to the ecologically sensitive nature of the site, which included water vole habitats, we applied and obtained an Environment Agency permit and provided an Ecological Clerk of Works with whom the GI team agreed access routes and supervised all plant movements throughout the works.
Our careful pre-planning and highly skilled workforce enabled all fieldwork to be undertaken below budget and within the agreed two-week period. Health, safety and the environment were prioritised throughout the works, in particular in overcoming the challenges of bad weather, soft ground, restricted access and minimising damage to the existing environment.
