The Canary Wharf estate is already home to a number of tall buildings – but rising out of the ground on the wharf’s western side, closest to the City of London, is a tower shaping up to be one of the most striking yet built on the site.
The 60-storey building will have an unusual irregular octagon-shaped concrete core, with a steel diagrid structure on the outside providing structural support and handily allowing the floor plates to have no internal columns.
The core is a number of storeys above ground during our visit, with the steel up to level two, and the diagrid structure set to begin installation shortly.
From a construction point of view, this project sees the steel and concrete subcontractors having to work hand in glove to make it a success, with the diagrid structure following the core closely and giving it structural stability as it rises. Expanded Group and VBH JV will have to work closely together to succeed.
Our tour is made up of a mix of local college and university students, people interested in construction, and some who are keen to hear more about this huge project.
Another complicating factor is the site’s location directly over London Underground’s Jubilee line tunnels – with piles for the tower installed in between and around the eastbound and westbound tunnels.
Lafia, a student in sustainable building, design and construction at Greenwich University, enjoyed the chance to see what a live site is really like.
“It’s good for students to see how a site looks,” she says. “It’s great to see more than just the theory.
“These events would be perfect for high-school students, too, to get them interested in the industry.”
The Canary Wharf Contractors team are clearly proud of the work done so far on this technically complex project – and with everything progressing as planned so far, it’s been an ideal team to throw open the hoardings and show the public what lies behind.
