We are undertaking detailed design of the refurbishment of the River Lea Crossing in East London. The bridge is a two-pinned arch structure comprising 16 riveted steel arch ribs.

Having previously undertaken a comprehensive programme of surveys, inspection and assessment we were able to demonstrate that refurbishment was a feasible option instead of replacement, drawing on the ‘build less’ approach in PAS 2080. The refurbishment scheme offers embodied carbon savings in the order of 50%.

The assessment included the mass concrete abutments to demonstrate their continued function and safety.  The design was managed in two phases: an ECI phase in which the refurbishment proposals were developed with the input of a specialist steelwork contractor, to ensure the proposals were buildable and to identify specific risks to the project; the second phase comprised the detailed design.

Our appointment includes fulfilment of the Principal Designer role and supervision throughout the  construction phase.
