Some interesting info from last week ... I recognise that photo

Leadenhall provides City with another icon
JANUARY 21, 2013 by NSC in NEWS



Leadenhall, otherwise known as the ‘Cheesegrater’, is expected to reach its maximum height of 225m next month (February), as Severfield-Watson Structures erect the final pieces of the structure’s 18,000t of steelwork.

The use of structural steelwork has played a key role in the design and construction of the iconic tower. It has a unique building design, with an external mega frame structure providing the lateral stability, rather than a central core, with an offset self-contained service core located on the northern vertical elevation.

The northern core contains lifts, risers, and toilets, and allows the main building to have large open spans with only six internal columns needed for the larger lower levels.

With its distinctive tapering shape the completed building will appear to be leaning away from St Paul’s Cathedral. The structure’s floorplates will have a variety of sizes ranging from 1,500m2 on the lower levels to 550m2 at the top.

Ground floor to level five is known as The Galleria and will be an open public area linking into nearby St Helen’s Square.

Practical completion to the shell and core is scheduled for mid 2014, and the building is set to achieve a BREEAM ‘Excellent’ rating.

I do believe so.

[Maderz]

I would have thought the glazing would join snugly to the steels edges.

Exactly one year since the first steel appeared above the hoardings:

Same. It's a bit of a shame really, particularly over the yellow steel side. I quite liked the brightness of it and the glass seems to dull that down alot. Hopefully when the glass is cleaned the steel will become more visible...

This building is sexual.

A perfect combination of the ultra modern and the traditional. Yes, we do have a great engineering tradition in this country. The victorians would be proud.

The first in the series of lumberjacks pictures is really amazing.

I showed this thread to a frenchman while we were discussing london vs paris. He was insisting that la defense was far superior to the city/cw in style. Lumberjack's pictures shut him up pretty quickly

Sun... not great visibility and still not taller than the Gherkin, windy weather due this week which may delay mega columns going up

forgot to post this one... from monument at sunset hence the weird pink cast on the steel.

I love the diamond motif that features on so many the City's skyscrapers now. I'd love to see this motif repeated in the redesign for the Pinnacle. In fact, I wouldn't mind seeing an exact replica of Foster's 2WTC design in NYC!

[potto]

good point. NEO bankside across the river too. Would like to see a play on this for the new Pinnacle.

Lovely shot Gothic. Its curious that this latest megalevel is being constructed in half floor sections, and that the west side is completed while the east side floors are now starting to rise. I was expecting construction of the megalevels to speed up as floorplates shrank but this doesn't seem to be happening. Can anyone explain this change in construction technique?

this was due to the crane being in the way so the constructed half the floor while the crane was removed.

Sorry, tried to post the pic direct to this site but it didn't seem to work. Something about too many URLs.

The slowing down is also due to the fact that the last week or so has been too windy for safe use of the TCs

Thanks everyone for your responses, much appreciated.

As I was taking that photo I heard a voice mutter "View's better from the top, mate", looked round to see a hi-vis clad man strolling off towards a lorry rub it in why don't you mate

Looks like the wind is finally going to die down tonight and tomorrow so we might see some more progress on the steel work
