Dundee City Council said in its latest announcement that the preparation works for the Broughty Ferry Flood Protection Scheme started this week.
Contractor BAM Ritchies will be at various points between Douglas Terrace and Beach Crescent between 8am and 5pm for four weeks, said the council.
Investigations operations, which officially started yesterday, will consist of exploratory investigations to determine ground conditions and ground water levels.
The results arising from the investigations will inform the structural design and construction method of the final flood prevention scheme.
It is expected that 80% of the funds required will be supplied by the Scottish Government Capital Grant for Flood Schemes. The remaining 20% funding has been included within the Dundee City Council Capital Plan 2016-2021.
During early 2016, the council sought the views of the communities affected on the preferred option which is a set-back wall solution which will comprise of a one meter high wall to the rear (roadside) of the footway.
Enhancements to the footway will be carried out alongside the wall works.
According to the council, the wall will include openings to allow for public access with gates that can be drawn over should a risk of flooding occur.
