Erith were employed by Sellar Property (London) to carry out the demolition of Fielden House, a 1950’s office building situated in London Bridge less than 200ft from London Bridge Station. Demolition works paved the way for a new 180,000 sq ft, 26 storey luxury residential block designed by Shard architect Renzo Piano.
Fielden House was situated within extremely close proximity to the Shard and London Bridge Station, with a footfall of 180,000 people passing through the station daily.
The scope of works included:
- Drain down, purge and isolation of mechanical and electrical plant
- Asbestos removal
- Top down demolition
- Soft strip
- Break out of ground bearing slabs and grubbing of below slab
- Pile probing to pile locations
- Installation of pile mat
- Weather proofing to exposed party wall
- Scaffold erection
- Temporary works
- Archaeological attendance
Throughout the duration of the works, noise, dust and vibration controls were implemented in order to mitigate any nuisances and safeguard the public whilst the works continued.
Due to a number of sensitive receptors posed by the location of the project, Erith implemented a number of provisions to ensure the smooths continuation of the works. Provisions encompassed:
- Monarflex sheeting – to ensure all debris fell within the fabric of the structure.
- Traffic Marshals and traffic management plans – protecting the public and ensuring the most efficient routes with regards to access and egress as well as mitigating CO2 emissions.
- Hoarding erection – ensuring no access to unauthorised personnel.
- Intricate demolition techniques – mini machines hoisted to highest level to work in a sequential top-down controlled fashion, working from the plant room to formation level.
- Implementation of a Neighbourhood Liaison Officer – ensuring all surrounding stakeholders are aware of the works and were able to have any queries answered.
Furthermore, the Museum of London Archaeology advised that the ground below the existing buildings was a 17th century burial ground used by Guys Hospital and there could be up to 1,000 bodies buried within the site grounds. We are advised that many of the bodies were donated to Guys Hospital for research by poor relatives of the dead who could not afford funerals. The hospital would then lay the bodies to rest following the research.
Demolition works were carried out via mechanical means. Plant used to demolish the building included 360 degree excavators fitted with pulverisers and a series of 13 tonne excavators. The machines utilised were best fitting for the nature and location of the works.
