Environmental Geotechnics is now of course considered on the
majority of projects both before and during development and for a number of
projects risk assessment relating to potentially contaminated land has been
undertaken and included in the interpretative reports. Two projects where this
have been a significant issue are summarised below
| The work at the former Butterley Engineering works,
Ripey,
Derbyshire comprised several phases of work. The first was to look at mining close
to the collapsed Cromford canal tunnel, which passes at depth below the site.
Further
phases of work were undertaken to determine the nature and extent of the made
ground and the conditions further afield. A final round of work was undertaken
to allow precise location of the tunnel, by drilling holes at close
centres through which a video survey could be undertaken. |
| At the site of the former Deakins Mill, Edgerton ground
investigation field work was undertaken to determine the nature and extent of
material filling a former mill pond, mill race and basement. In addition further
ground investigation, monitoring and slope inspections were undertaken to assess
the stability of the slopes adjacent to the river, which comprised made
ground, in order that a safe "no-build" zone could be established. |
