Hammersmith Bridge Temporary Stabilization Works (Pedestal Strengthening)

London, UK · 2020–2022 (stabilization works) · Included in overall repair costs; specific cost for temporary stabilization not clearly separated but contributes to the £250m total.

The judgement call

Account-gated at launch

The temporary stabilization was a crucial step to prevent further deterioration and allow for future permanent repairs. - The use of bespoke concrete and external frames provided temporary support to the cracked pedestals. - The project highlighted the challenges of sourcing materials and managing complex logistics for urgent infrastructure repairs. - Discussions around a temporary 'double-decker' bridge or other temporary crossings underscore the urgent need for alternative solutions during prolonged closures of vital infrastructure.

Key engineering challenges

Stabilizing fractured cast-iron pedestals, critical components of the bridge. - Installing steel props and pouring bespoke concrete into the pedestals. - Working within the constraints of a Grade II* listed structure. - Overcoming delays in acquiring specialist materials (e.g., steel from Ukraine).
