A total of 835m3 was supplied to contractor Sacyr, Wills Bros Ltd, Somague Joint Venture for the bridge deck of an overpass bridge over the A6 road as part of the DfI Roads’ ongoing A6 dualling project from Dungiven to Derry/Londonderry.

Due to the scale and nature of the deck pour, it had to be delivered and installed in one continuous pour. FP McCann worked closely with SWS JV to put a detailed plan in place to ensure the job went smoothly.

In total, 104 loads of concrete were delivered on time and to specification. On the day, the lorries clocked over 7,000 miles and were able to keep up with the demanding supply rate, completing the pour in approximately 12 hours.

A fleet of 26 of FP McCann’s own truck mixers including 6 wheelers, 8 wheelers and units were used on the day. This scale of delivery was needed to keep up with two concrete pumps at a reach of 55m and 48m continuously pouring the deck.

FP McCann utilised two of its batching plants; Knockloughrim in Magherafelt and Bradley’s in Kilrea. The Ready Mix Concrete used was a 50N designed mix, incorporating GGBS, which helps to control the curing process of the concrete and is a more environmentally-friendly mix.

John Diamond, Structures Agent, SWS JV, said: “Organising the pour of the bridge deck posed certain logistical issues as it needed to be completed in a continuous pour. We liaised with FP McCann, who confirmed they had a large fleet of vehicles able to service the 12-hour pour, as well as batching plants capable of producing a large quantity of concrete to specific design requirements. We worked together with FP McCann ahead of the pour date, ensuring everything was in place for the day. Despite wet conditions, the concrete was supplied on time and to specification, with the whole pour running smoothly from start to finish.”
