Proving or As Built Surveys
  
Where construction is underway or just completed, we can provide an independent check and validate either existing survey work or the position and level of construction.

This validation work can be on:
  • Building sites
  • Checking verticality of steel
  • Slab or finished floor levels
  • New boundaries
  • Earthworks volumes
  • Site Boundaries
  • Survey control station coordinates

For validating existing survey plans, we would advise a 100% visual content check, followed by a 10% re-survey to check dimensions, alignment, survey control and discrepancies in height.

Proving surveys may also be combined with an update survey where we check and continue survey work started by ourselves or others. Some projects require a monthly, yearly or periodical re-visit to re-observe the same area. This is usually the case where sites are under constant development, or have shifting earthworks that require tracking for volumes of cut and fill.

On request, a comprehensive survey report can be compiled to detail the results of the proving survey.

Please call us to discuss your requirements.

Examples of relevant experience include:

  • Proving survey of M6 junctions 11 to 17.
