Bam Ritchies has been appointed to carry out the ground investigation of a ‘complex’ landslip in Gardenstown, a coastal village cut off since November 2017.
The landslip first occurred overnight on 28 November last year, depositing debris from the cliff to the road below.
The road has been closed since due to the risk posed by the insecure hillside. Temporary protection was put in place, and the road was reopened for a short time. However further slippages meant the road had to be closed again.

Investigation work will begin this week, and is expected to last four weeks, to find a permanent solution for the area. Borehole drilling will commence from Wednesday (14 February).
Once the ground investigations are complete, the stability of the slope will be modelled to estimate the volume of material which may still fail and inform the design of a solution.
Aberdeenshire Council head of roads Philip McKay said: “It is extremely unfortunate that the road layout in Gardenstown means closure of Harbour Road at this location prevents all vehicular access to the New Ground, the harbour area and Seatown.
“However, the slip is deep and extensive and unfortunately there is no quick or easy solution to a landslip like this.
“From time to time we have had to deal with landslips impacting on public roads across Aberdeenshire, but this one is perhaps the most complex we have had to deal with.
“Ground investigations are due to start, expected to take four weeks to complete. The information we gather from this work will be essential as we work towards a permanent solution.”
