Costain has received two contracts worth £50m ($80.6m) for infrastructure upgrade works at two airports in the UK.
The company will deliver the contract for the BAA, which is the implementing agency for the projects.
As part of the first contract worth £18.6m ($30m), Costain will renovate Manchester airport's main runway as per an existing framework agreement.
The project will run through to September 2011, during which the airport will operate 24 hours a day by utilising the second runway.
The company also received a four contract worth £8m ($12.9m) per year, to act as one of the suppliers for the local project integrator framework at London Heathrow Airport.
Work on the contract will begin in March this year, according to constructionenquirer.com.
Costain chief executive Andrew Wyllie said the two contracts will help the airports to meet the increasing needs of passengers in the future.
