A historic north-east pier which collapsed last year could be restored using some of the original granite blocks.
The council is looking for a contractor to complete the £75,000 restoration of the Railway Jetty at the Banff marina.
A section collapsed last year due to heavy rain and temporary repairs were carried out so sailors could continue to use the facility.
Gabions filled with smaller rocks have been placed on the collapsed section as a temporary measure.
Now the local authority wants to bring in a firm to finish off the project.
Many of the blocks that fell into the water were successfully recovered and have been kept at a council depot near Macduff.
An Aberdeenshire Council document going out to potential contractors said initial repairs were carried out with gabions last summer and the unstable section of the jetty was demolished.
The local authority commissioned the British Geological Survey (BGS) to carry out a building stone assessment on the material recovered.
It said it would be “prudent to carefully examine” the state of the stones to make sure they were fit for purpose.
The document said it would be possible to find matching stone from different quarries around the country.
It said: “Several quarries in Scotland produce grey granitic-rock and several others produce dark grey metamudstone; any of these should provide a reasonably close match for the two main stone types in the Railway Jetty at Banff Harbour.
“All of these quarries generally supply crushed stone for use as aggregate, not building stone, but it might be possible to obtain blocks suitable for building on request.”
Last night, Banff Councillor John Cox welcomed efforts to restore the jetty.
He said: “It was unfortunate circumstances that lead to the collapse and I was glad nobody was hurt.
“Obviously this is the final phase for the pier and it will be reinstated back to the original construction of the harbour.
“I hope there’s not too much disruption to boat users during the construction.”
An Aberdeenshire Council spokesman said: “The repairs are the culmination of a series of ongoing work to restore Banff Railway Jetty to its former glory after part of it collapsed last year.
“A number of interim measures have been put in place to ensure that the Grade A listed structure is safe, but we are now in a position to reinstate it as it was before the collapse.
“The tender will allow us to work with a partner in seeing how best to complete the repairs.
“It is intended that the ground investigations will begin later this year and construction works in Autum 2019. We hope they will completed in spring 2020.
“We have planned for the work to be carried out during times that will keep disruption to our customers to a minimum.”
