Asbestos removal and demolition of three office blocks, opposite the Guildhall and surrounded by further office buildings.
Scope of Works
- Having removed and disposed of the asbestos, the floor by floor demolition commenced.
- Concurrently however, access was required for the Museum of London to investigate basement areas, as the site was known to be of significant historic value.
- The main archaeological excavation had to be carefully programmed to facilitate a complex temporary works scheme.
- Wholesale excavation of the site would have undermined adjacent roads and foundations, therefore the project was split into three distinct phases.
- As the Museum completed their work, John F Hunt revisited the site to remove old foundations and obstructions prior to handing the site to Sir Robert McAlpine and the piling rigs.
- Although the demolition was relatively conventional it was the careful liaison and integration with the archaeologists that is particularly worthy of note.
- The temporary scaffold structure offering protection to the excavation was the largest ever erected in the city to date and covered nearly an acre.
- Suppression methods were utilised to combat dust pollution and quieter concrete crackers were used instead of noisy breakers.
- Demolition was completed within the 64 week programme and within the £3,500,000 contract sum.
