The company, part of Lagan Construction Group, will carry out work in Gibraltar and Cyprus for Defence Infrastructure Organisation - with the work valued at a combined £31m.
It is also Florida-bound after winning a deal with the US Naval Facilities Engineering Command for runway repairs at a field in Milton in the state.
The contracts are the latest in a long line of big-money airfield and runway deals for the business - now regarded as an international specialist in airport jobs.
