British Land has launched a full investigation into the breakage of two steel bolts at its recently completed 122 Leadenhall Street building, popularly known as the 鈥楥heesegrater鈥.

In a statement the developer said two steel bolts recently broke on the tower, the City of London鈥檚 tallest building.

No one was injured in either incident and there is no risk to the structural integrity of the building, British Land said.

The investigation will be carried out by the building鈥檚 contractor Laing O鈥橰ourke and structural engineers Arup and an examination is being undertaken of the remaining bolts.

British Land said the bolts connected the nodes on the megaframe, but said the design of the structure 鈥渁llows for isolated events of this type and do not affect the structural integrity of the building鈥.

One part of one of the bolts that broke became dislodged and fell to the ground at the side of the building within the hoarding line, British Land said.

An area has been cordoned off around the base of the building while this process is ongoing and the building control department has been notified. 

In its statement British Land said 鈥減ublic safety is our number one priority鈥, adding that 鈥渁n update will be provided as soon as we are able鈥.
