The owners of the 222-metre (734ft) “Cheesegrater” building, the second tallest building in the City of London, are to replace dozens of long bolts on its structure after it was revealed that another one had fractured.

The bolts, among 3,000 on the building’s 15,000-tonne frame, are each just under a metre long. Two snapped in November, with some debris falling to the ground from the fifth floor. Nobody was hurt, but an area below the tower is still cordoned off. — theguardian.com

No-one was injured but an area around the 47-storey Leadenhall Building in the city has been cordoned off.

It fell from the fifth floor to the ground at the side of the building - another bolt also broke off but was contained within the skyscraper.

It is understood the bolts are about the size of an arm and the piece that fell was about the size of a hand. — bbc.com

Someone has told the bouncers to be nice. It is now standard for architectural anoraks like myself to find ourselves challenged by smile-less security as we go about our blameless business – no loitering, no photography, no looking, as if al-Qaida scouts would do their dastardly work in this way or as if, years after the invention of the camera phone, photography can be controlled as it could in the age of the tripod. But not at the base of the Cheesegrater. — theguardian.com

The series of videos below offers a fascinating insight into how this generation of "starchitects" behaves under pressure, as they each pitch to win one of the most high-profile competitions in recent years: a new tower for L&L Holding Company on Park Avenue in New York. The site has such daunting neighbours as Mies van der Rohe's Seagram building, and it will be the first full-block office tower to be built on the street in almost half a century. — guardian.co.uk

"It might have been easier to completely rebuild it," Rogers tells me. "It was a very weak structure with very thin walls. We had to shore the facade, then almost completely rebuild it inside. But the thing they insisted on, and I think they were proven right, was keeping the circular form, the historic form. It's not just a building – it's a piece of Barcelona." — Guardian
