Every site investigation should begin with a desk study.
This is an
office- based exercise in collating all available published information.
initial walk over / site visit is made during the desk study.
The desk study includes :-
of historical mapping,
BGS borehole logs,
land / landfill directories,
Local library records,
Interviews with local sources,
Previous site investigation reports,
Regulatory bodies and the physical inspection / reconnaissance of the
site and environs.
Once the site has been seen and desk study information studied the ground
conditions are more readily visualised and a conceptual model of the site
can be built up. Any potential difficult ground conditions e.g soft and
variable drift materials, man-made caves, landfill gases, potentially
contaminative past activities that have taken place on the site etc. can
be better understood.
