Form of Contract
NEC 3 Option B

The A635 Holmfirth Road (Rowgate Junction) had suffered long term ground movement (65 years) which caused repeated carriageway and retaining wall failures, leading to partial closure of the road for many months. The project works were designed to rectify this.

The works involved:

  • Installation of contiguous piled retaining wall (12m long, 450mm diameter) reinforced concrete piles at 750mm centres
  • Construction of a reinforced concrete capping beam (1.4m x 1m)
  • Installation of rock anchors comprising of 20m long, 20mm diameter anchors declined at 55° terminating in a steel bearing plate cast into the reinforced concrete capping beam
  • 60m of road and foot path were reconstructed including new kerbing and a new masonry parapet wall
  • Replacement and reinstatement of surface drainage affected by the original slippage

The A635 Holmfirth Road is a main transport route and therefore it was vital that the road remained operational.  Despite restricted working areas, we maintained traffic flow using traffic lights which minimised disruption to the local community.

 

Excavations were undertaken in a phased and controlled manner to mitigate any collapse.  The piling choice was also carefully considered to prevent localised wall overloading and potential failure.
