Plate Load Testing in Historic Bath


Constructive Evaluation (CE) were instructed recently by Stress UK as part of structural reinforcement works. The works were relating to the development of improved access to an underground vaulted space which will form part of a new Clore Learning Centre for the Roman Baths in Bath. The scheme will also include essential road repairs. The project is under the overall management of Bath & North East Somerset Council.

To provide wheelchair access to the underground areas of the new Centre an existing Victorian stone pillar needs to be demolished and replaced with a new column nearby – however, the site for the proposed column is underlain by Roman archaeology, including a recently discovered Roman stone lined drain which served a Roman plunge bath.

It is crucial for the scheme to form a sound foundation for the road above that performs under load, but also respects the Roman archaeology and does not compromise the integrity of the natural hot water sources below. To facilitate this CE carried out in situ Plate Load Testing which provided necessary design assurances to allow the construction of a new cantilever column to support a reinforced ceiling beam, this in turn supports the road above. The plate testing work required prior approval by both Historic England and the Environment Agency.
