We are often asked what points (on a building etc) we actually survey; and whilst this may seem to be a trivial matter experience has told us that ‘the devil is in the detail’ and so I will, over the next few updates, outline the critical features that we survey.

Gutters; we endeavour to always survey the top lip of the gutter using our laser theodolites as shown in the photo below left. We have found that this can be consistently and accurately surveyed without the need for offset measurements etc that can introduce errors.
