The detail

The ambitious DBFO 1 project involved the upgrade of the motorway network into Belfast from the North and South, as well as the enhancement of the A12 Westlink. Split into four schemes, the 45-month programme was delivered by almost 500 people over 2.4 million ‘man-hours’ and featured the management of 141 suppliers and 80 sub-contractors. Completed five-months ahead of schedule, with each key milestone similarly achieved early, the project was notable for its high quality design – achieved through our effective coordination of multi-discipline engineers. Inclusive of two underpasses, four replacement bridges, one steel footbridge and six bridge strengthening works, the DBFO 1 project also incorporated the installation of £10 million of motorway communication systems and £7 million of services diversions. In addition, significant online widening, from two lanes to three of the existing motorway, plus widening exercises at the M1 Junction, M2 Junction and A12 were prominent components of this complex civil engineering project.
