Steel underway for latest City landmark tower

Posted on by in Weekly News

Structural steelwork erection is underway on the 50-storey 8 Bishopsgate project, the City of London’s latest landmark high-rise development.

Featuring a host of sustainability credentials, the EPC A rated building is set to be the UK’s tallest structure to achieve a BREEAM ‘Outstanding’ rating. It will also have 30% less structural embodied carbon than London tall building benchmarks.

The completed building will offer 52,900m2 of office space in what is said to be the UK’s most sustainable commercial tower.

Working on behalf of main contractor Lend Lease, William Hare is fabricating, supplying and erecting 8,500t of steelwork for the project.

Bespoke fabricated steel sections, which have been optimised for individual unique loads, are being used throughout. Project architect WilkinsonEyre said by rationalising the building’s frame, the design needs 25% less steel, which saves approximately 5,000 tonnes of carbon.

Another initiative to make sure the steel frame meets the project’s high sustainability goals is to leave the majority of it exposed within the completed structure.

“The exposed steel frame provides the building with a modern industrial-looking office environment, but importantly we use less materials, which is good for sustainability, to enclose the columns and beams,” said Lend Lease Project Director Paul Gransby.

Starting at ground floor level, the steel frame incorporates three distinct blocks that are stacked-up to form the overall building.

A low-rise block extends up to level 11, a mid-rise one, which actually sits behind the lower block, starts at sixth floor and goes up to level 26, and then a slim high-rise block tops out at floor 48. A three-storey pavilion is then positioned above this floor, incorporating a public viewing gallery and a plant zones.

8 Bishopsgate is due to be complete by the end of 2022.
