Geophysical information can be used to identify geological features, some of which may be a problem during the planning, design or construction of a new development. The location of magnetic dykes, the investigation of buried channels, or of landslips, the determination of the thickness of drift deposits or the identification of natural or man-made cavities are all problems which can be studied by geophysical surveying methods on both a regional or local scale. The information obtained can then be incorporated into factual or interpreted engineering geological maps for use by planners or engineers.

In this paper, the contribution that geophysical surveying methods can make at the planning, design, construction and monitoring stages of a development is examined and illustrated with a number of case histories.
