The Job

Asbestos removal and demolition of three office blocks, opposite the Guildhall and surrounded by other office buildings.

The 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.

Demolition complete, the main archaeological excavation had to be carefully programmed to facilitate a complex temporary works scheme; wholesale excavation would have undermined adjacent roads and foundation. There were three distinct phases and as the Museum completed their work, we 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.

Environment

Suppression methods were utilised to combat dust pollution and quieter concrete crackers were used instead of noisy breakers.

Delivery of Services

Demolition was completed within the 64 week programme and within the £3,500,000 contract sum.
