Wire Sawing Procedures deployed to remove a reinforced Bank Vault in the basement of a Grade 1 Listed Building in London
Many older buildings in the major cities in the UK are routinely renovated and refurbished for private residential use. The example illustrated here is a Grade I listed building in the centre of London. The conversion necessitated the deconstruction of a heavily reinforced concrete basement which housed a former Bank of England holding vault. Being Grade I listed, strict constraints were imposed on the method of its removal. Diamond sawing and drilling proved to be the only acceptable way of completing the job on time and to the satisfaction of the client.
Whilst the walls and the roof of the building were built during the 16th and 17th centuries, the concrete walls and ceilings of the vault were added much later and were tied into the existing structure in the majority of areas. Operational Constraints The Project Engineer insisted that all work within the building should be non-percussive in order to preserve its structural integrity - this applied even to f ixing holes. The only method that was approved was diamond cutting since this gives the advantages of minimum vibration and noise and also reduces dust and debris.
