Refurbishment of the Tower of London's Middle Drawbridge

Middle Drawbridge refurbishment.

ANG provided Cost Consultancy on the refurbishment of the Middle Drawbridge at the Tower of London.

Built in 1834 to allow munitions to be brought into the basement of the iconic White Tower from the wharf, the original drawbridge was in disrepair and in danger of collapsing. The Historic Royal Palaces, in partnership with English Heritage authorised the project to demolish and rebuild a new and strengthened drawbridge using mighty English oak.

The bridge has previously undergone various adaptations. The last time it was completely replaced was in 1915.

A fundamental element of the project was to ensure that the dimensions and original construction of the bridge were accurately replicated. A 3D laser scan of the bridge was executed before it was demolished.

The complexity of the work meant that the drawbridge could not be built off site, as had originally been considered.

Despite issues with heavy rain and flooding the bridge was completed on schedule.
