Building company Lagan Construction has won contracts worth £16m to redevelop three airports in Scotland, England and the US.
The deals mark a growing expertise in the airport field for the Northern Ireland company, said CEO of Lagan Construction Group Colin Loughran.
"Having completed projects on over 50 airports across five continents, airport infrastructure works are a core part of our business and our teams are experienced in providing the engineering skills and technologies necessary to deliver both airside and groundside support facilities," he said.
Work at the Minot Air Force Base in North Dakota will consist of placing 45,000 tonnes of gravel and 35,000 tonnes of concrete on the runway.
The £8.2m four-month contract is expected to start in May.
The £3.7m St Mary's Runway Resurfacing contract on the Isles of Scilly will involve runway resurfacing and reconstruction which includes the upgrading of airfield ground lighting, drainage and apron reconstruction.
The contract is due to start in March/April to last some six months.
