Ground Investigations Completed
1. 14 boreholes sunk were showing very significantly varying elevation in
granite bedrock surface over the site.
2. Those boreholes that struck rock did so between 4m and 17m below the
project’s formation level.
3. A number of boreholes were terminated 33m below the project’s formation
level without encountering rock.
4. A program of seismic survey was executed with the objective to
bridge/interpolate between the point information at the boreholes for
producing a seamless map of the bedrock surface variation over the project
site.
5. 3 seismic traverses were made.
