CTBUH - 2009 Best Tall Building Europe

The Broadgate Tower is the first developer-led speculative office tower to be built in the City of London and presents a model for the next phase of development of the City cluster. Its striking structural form, born out of an innovative design response to site constraints, is reflected in the major facades. The Broadgate Tower creates a landmark for the northern gateway to the City. The side-mounted cores provide clear and open floor plates. They are reached via Destination Hall Call Control double deck elevators—the first such combined installation in Europe.

At ground level, the covered Galleria delivers units for shops and dining, high quality public space and creates a route through from Broadgate to the north and east. The site was created by building a 2.3 acre raft over the existing rail tracks running into Liverpool Street Station. The structure was developed in response to the need to span these tracks, whilst the form is specifically designed to maintain the St. Paul’s View Corridor, which bisects the site.

The Broadgate Tower allows British Land to increase the diversity of tenant space in Broadgate, provide more ground floor space for public use, maximize the potential of a site near a major transportation hub and create a new pedestrian route across the site.

Sustainability was an integral part of the design approach from the inception of this project, which lead to an efficient building without compromising on operational cial grated pits sunk into the surface of the Galleria and Plaza and there will be a “green” wall at the southwest of the Plaza designed to screen the three-storey wall performance. The landscaping at The Broadgate Tower provides quality urban spaces and amenities. 23 trees planted inside and outside the Galleria will add to the relaxed atmosphere of this development. Up to 13 meters (43ft ) tall, these trees will sit in speof Broadwalk House.

Another note, CTBUH measures it at 178m. Is this reliable or just a mistake?

179m to be exact

[wjfox]

It looks super-slim from this angle -

Finally got around to visiting Broadgate one slack Friday evening the other week. Stunning, just stunning.

But why don't the warning lights flash anymore? It added a bit of 'Tokyo-chic' to the London skyline at night! CAA again?...

I think the locals complained.

[jandow77]

Oh, well I understand their sentiments entirely, what with all those 150m+ resi blocks around Broadgate looking directly across to the roof......Jesus wept!

Hi, I was looking to see if I can get someones insight in to Broadgate tower.
I'm a Structural Engineering student doing a project, one small part of which requires an analysis of lateral stability of a structure illustrated using a case study. I choose Broadgate tower for two reasons, the facade emphaises the steel structure behind and that the A frame struts on the east face sit outside the footprint of the building its self.
I just want to verify want I have reserached so far is correct, or if I have missed anything obvious.
As I can gather, when the wind load hits the face of the building it is transfered throught the facade by bending to the hortizontal trusses located on every sixth floor. The horizontal trusses then under go bending to transfer the load to the X bracing, rather than the membrane action of the floor? I believe the vertical tube truss around the building provides stability rather than bacing to a central core? Has the X bracing been designed for just tension or for both tension and compression? In such a large structure I would expect both tension and compression, that would require very heavy members. For the X bracing and struts, what column/beam and HSS sections were used?
I do apologise for all the question, any insight at all would be great help! Thanks.

i like it, could be taller though

[ferge]

It shouldn't be taller, it is on the very outskirts of the city cluster - any taller and it would have completely unbalanced what we have now.

I found this video the other day on Youtube, whilst searching for 100 Bishopgate flyovers. I don't recall seeing it at the time, but it is nice to watch all the same and gives a nostalgia kick.. doesn't seem that long ago that we were waiting for them to break ground on this one.



It is also amazing to look at the changes that have happened in such a relatively short amount of time.
