Morrison will restart work next week on the £3m Saltoun Square project in Fraserburgh.
Work came to a halt last November when original contractor A.D. Walker went into administration.
The project was originally approved by councillors in 2016 and work began in May 2017 to renovate the Faithlie Centre.
Morrison is expected to complete the project by the end of October.
Chair of the Banff and Buchan Area Business Services Committee Cllr Jim Gifford said: “It is essential that we fulfil our commitment to this historic project, and I am pleased that we have a contractor in place who can complete the work this year.
“The impact of this on the public purse has been carefully considered and we are confident that this is the right approach in the circumstances. We look forward to watching this come to completion.”
