Two Cork brothers who were based in the UK have sold their construction empire in deals worth an estimated €510m euros.
Tim and Tom O'Connor have never courted the limelight, even though they have regularly featured on the Sunday Times Rich List for Ireland.
They founded O'Connor Utilities in 1994, consolidating and growing a huge construction and services operation, specialising in work for major utilities in the north of England, including electricity, gas, water and telecoms.
