Fundamental Bench Mark: Duncansby Head FBM (Duncansby Head FBM)

The Ordnance Survey Geodesy Team have asked to be notified of any development proposals which meet the following criteria: 1) If an FBM falls inside the boundary, or within 30m of the boundary of a proposed development upon completion. 2) If an FBM falls inside the boundary, or within 30m of the boundary of the "construction area" or any other temporary area of a proposed development. They also wish to be notified in any other case where an FBM may be at risk of disturbance. Should an FBM be threatened they will create a new one nearby at their own expense before the threatened one is lost. This is to ensure the continuing integrity of this vital network.
