February 2021 update

A procurement exercise is currently underway to appoint a steelwork contractor competent in assessment and inspection of historical wrought iron structures.  The contract will require the contractor to design a series of temporary works systems to allow separation of the chain links and hangers in various locations for further inspection and assessment.  A programme and methodology of in-situ non-destructive testing will also be developed.  It is a critical requirement of this phase to understand how fatigue has compromised aspects of the structure over the 190-year life.

The investigation and testing contract will be developed alongside an accredited Conservation Engineer who will assist in ensuring the methods proposed are acceptable to Historic England.  Before the works can commence on site, Scheduled Ancient Monument consent will be required once the testing plans are developed.

Tenders are due back for the Investigation and Testing design contract on the 26 February 2021.
