Dunn spent 32 years with BAM Construction, where he was influential in the significant growth of its north east business and brought in £2bn of work in his last 16 years with the contractor.
He left Bam and took a commercial director post with C Spencer in April before accepting the job to return home to Scotland to run Miller’s Construction operation.
Chris Webster, Miller chief executive, said: “We are delighted that Charlie is joining our senior management team.
“Charlie is a well-respected industry figure, who knows how to deliver successful projects for clients.
“Scotland is an important region for our business and I have every confidence that Charlie will be instrumental in delivering our services as we progress with our strategy of providing ‘end-to-end’ services for our clients across the UK.”
Dunn said: “Over the last 12 months, there have been a number of high profile appointments to the senior management team and I very much look forward to playing my role in Miller’s growth story.”
