Direct Drive Launch Box GI
When Stockton Drilling realised they had water ingress issues in their Launch Box, they turned to Soil Engineering for a rapid turnaround Ground Investigation
Supplied with a detailed specification and high quality site information, our Estimator turned around the bespoke quote in a day, and we were able to be on site with in-house resources in under a week despite an already heavy workload across the country.
Our site team undertook rotary cored holes at both the launch pit and proposed reception pit locations to confirm ground conditions. The core was logged by our onsite Engineering Geologist, who also supervised the completion of packer permeability testing to improve the site hydrogeological model. Standpipes were installed in the majority of holes to allow continual monitoring during follow-on remedial works. Dynamic probe testing was completed at both locations to prove the consistency of the overburden deposits, whilst plate bearing tests were used to indicate the continued suitability of the ground for a crane platform.
In all a total of 8no boreholes were drilled to a maximum depth of 17m, whilst dynamic probes extended to 13m below ground level. Plate bearing tests were completed at ten locations to a maximum load of 620kPa. Data recovered from the investigation allowed the Stockton to put in place suitable controls to manage the groundwater issue in the launch box, and avoid a similar occurrence in the reception box. Data was issued daily throughout the works, and as both PDF and AGS format files on completion of the investigation.
