Strength through innovation
The DLR Three Car Capacity Enhancement project specified extensive strengthening works to original concrete and steel viaduct structures.
Working closely with Gifford, we used strain-gauging to determine actual, rather than theoretical, stresses at the bid stage. This process enabled us to show that the residual life of the existing structures was greater than originally thought.
It also reduced the extent of the strengthening works, provided significant cost savings, and helped to mitigate the environmental noise impact of the contract.
