We have just completed a Phase 2 geoenvironmental ground investigation for a new industrial development on Tyne Tunnel Trading Estate for a developer client.
The investigation comprised a series of cable percussion boreholes sunk to 10m bgl to provide information on ground conditions and to allow in situ testing to be undertaken (SPTs), and to enable samples to be collected for laboratory analysis (geotechnical and chemical). In addition, a series of trial pits were excavated across the site using a JCB 3CX Sitemaster, the trial pits were sunk to the maximum reach of the machine (4.5m bgl).
The investigation was designed using a 35m grid non judgmental sampling strategy, a cost effective approach for an initial investigation.
The final data once received back from the testing laboratories will allow foundations for the new units going on the site to be designed, and it will also allow a Phase 2 report to be prepared for the site, inclusive of human health and controlled waters risk assessments (Generic Quantitative Risk Assessment) to support final planning condition discharge for contaminated land.
We are also preparing a similar investigation for a new industrial facility in Darlington, it is good to see confidence returning to the marketplace and seeing clients taking sites forward again to create employment in the region.
