A BUSY MAIN road in West Yorkshire, which links to the A1 and M1, has remained open during construction of a new motorway bridge, with help from shoring firm Groundforce.
Equipment was installed in two cofferdams either side of the relatively narrow Knottingley Road to support it during the building of piers for a bridge that will carry a stretch of the rerouted A1M.
The equipment included a modular mega brace, a maxi brace, HSK80 cross struts and KD6 heavy-duty trench sheeting. The required cofferdam was 39.8m long, 5.5m wide and 2.7m deep.
Main contractor for the Highways Agency project was RMG (A1) Construction joint venture, which designed the cofferdam size and loadings. Harrogatebased Groundforce designed the frame layout, which was installed by K Rouse Civil Engineering.
