Drawing Validation Surveys

Check surveys for cost effective CAD plan validation

Where plans exist but their accuracy is in doubt or where change management has been poor, a check survey can be a very cost effective way to bring them up to date.

Measured Check

We are able to compare distances on the drawing with dimensions taken on site and produce a report indicating where any inaccuracies lie. 3i Surveys can report on percentage variation between drawing and situation on the ground as well as any changes in the buildings layout. We can then update the plans accordingly.

Visual Check

Where dimensional accuracy is of low priority, we can carry out a quick walk-through of a building to determine whether changes to the layout of the building have been made and, if so, survey any changes. Drawing Conversion Where only paper drawings exist and where finished quality is not a major issue, we can convert them quickly and inexpensively into AutoCAD format either by vector conversion, scaling or scanning and over drawing.
