Steel frame set to complete Broadgate development

Work is progressing on 2 Finsbury Avenue (2FA), which is the final phase of a 10-year redevelopment of the Broadgate Campus in the City of London.

The biggest phase to date, on what is the capital’s largest pedestrianised neighbourhood, 2FA consists of dual office towers, sat on a 12-storey podium. The towers will top out at heights of 100m and 170m respectively, helping the scheme to deliver more than 75,000m2 of workspace.

2FA will be an iconic addition to London’s skyline, as the towers will be instantly recognisable landmarks, characterised by innovative triangular patterns combining a solid and glazed sawtooth-shaped façade.

Working on behalf of the client British Land and main contractor Sir Robert McAlpine, William Hare is fabricating, supplying and erecting 10,000t of steelwork for the project.

Space is at a premium on the site, with little or no room for material storage. Steelwork is delivered either via Sun Street or Wilson Street, along the site’s north and western boundaries, and is placed adjacent to the erection area.

Highlighting the site’s constraints, the eastern end of the plot does not offer a suitable location for a tower crane as the boundary sits close to some existing buildings. To solve this challenge, a steel-framed gantry (see picture), weighing more than 50t and connected back to the east core, cantilevers out over Sun Street supporting one of the project’s tower cranes.

The steel erection programme is due to finish at the beginning of 2026, while the entire 2FA project will complete in June 2027.
