The Irish Concrete Society has recognised FCC for the design and construction of the M50 in Dublin in the Civil Works category.

These awards are given out annually for construction work performed in Ireland that uses concrete as the main construction material. The panel of judges noted that the structure was an innovative solution that combined in situ elements with prefabricated elements, with an especially complex geometry that involved one of the country's busiest junctions which remained open to traffic during the construction.

In 2007, FCC, in a joint venture with other companies, was awarded a 265 million euro contract for the construction and operation of the M-50 expressway in Ireland. The contract called for the design, renovation and operation of Dublin's M-50 bypass, including the widening of lanes along 24 km of the road and the operation and maintenance of another 19.3 km as soon as the contract was signed. The term of the concession is 35 years.

The expressway is operated using a free flow toll system. The concession holder is paid by the government for availability in consideration for the investment and services rendered. The payment is subject to penalties if lanes are closed, depending on how long they are closed, the days and times of the weeks when the closings occur, the number of lanes closed and the length of road that is closed.
