Projects » Selly Oak Phase 1 Temporary Wall

Selly Oak is an area of Birmingham notorious for congestion and as part of the phase 1 bypass scheme, a new roundabout leading to the Phase 2 works and a replacement bridge were required over the Dudley No.2 Canal.

The new bridge over the canal was to be widened to accommodate four lanes of traffic.

The new bridge was constructed using a phased methodology thus ensuring that traffic could use the existing bridge. On a secondary bridge construction phase, live traffic was required to be transferred onto a newly cast section of the bridge.

Birse Civils Ltd commissioned PaSCoE to provide a number of temporary and permanent works on the project, including the provision of temporary wingwalls to a new section of bridge to support live traffic loading immediately behind the wall face.

PaSCoE detailed a number of temporary wingwalls for the 3 phases of the construction works including mass concrete and anchored earth. The third phase included the use of a reinforced earth design to create a wingwall over 5.0m high and was designed by PaSCoE to have a design life of 2 years taking into consideration UV degradation for the exposed geogrid reinforcement.

The temporary wingwall was used for over 6 months and was buried when the final section of the new bridge was cast and backfilled.
