Work to Begin on London's "Cheese Grater" by Richard Rogers
http://archrecord.construction.com/n...chitecture.asp

Quote:
London's high-rise architecture has a culinary bent of late. First there was the “Gherkin” by architect Norman Foster; now there is the “Cheese Grater” by Rogers Stirk Harbour and Partners, London. The city's next major high-rise, mothballed for three years during the foundation stage but about to spring to life, got its nickname thanks to its silvery leaning south facade. Passersby likely will find the profile of 122 Leadenhall Street to be the building's most striking feature. But project engineers are more intrigued by the node connections within the structure's expressed structural-steel megaframe.

The 224-m-tall building, nicknamed Cheese Grater because of its one sloping facade and expressed structure, was mothballed three years ago.


Prefabricated nodes to ease construction and provide joints at Richard Rogers' 225 m tall "Cheesegrater" tower.

“The most interesting part of what we have been doing over the past several months has been the analysis and detail design of these nodes,” says Damian Eley, associate director with the project's structural designer, Arup Group, London. “It's visual engineering,” he adds.

Three competitors—London-based Skanska Construction U.K. Ltd.; Mace Ltd., along with Laing O'Rourke Construction Ltd., Dartford; and Sir Robert McAlpine Ltd., Hemel Hempstead—are due to bid on the construction contract soon. Co-developer British Land Co. PLC., London, with Oxford Properties Group, Toronto, hopes to get a contract signed this summer, aiming for shell-and-core completion around mid-2014, says Matthew White, construction executive with British Land. With contractors hungry for work, “it's the best time to secure a lump-sum, fixed-price contract,” he says.

Designed by Rogers Stirk Harbour, the 224-meter-tall, 56,700-sq-m building will rise from a roughly 60 x 50-m footprint. Rectangular floor plates will reduce in area from 1,950 sq m at the lowest level to around 560 sq m at the highest. The structural-steel core will be anchored to the main frame's vertical north side.

The design for a sloping south side was driven by the need to avoid blocking views of St. Paul's Cathedral, just over one kilometer to the west, says White. Unobstructed sightlines to the 17th-Century cathedral are an important zoning criterion in central London, he explains.

Having no central core, the building will be stabilized by external megaframes of inclined steel columns with H-sections up to 80 centimeters sq. The building's composite floors will incorporate 70-cm-deep steel beams spanning between vertical steel columns. The megaframe columns will intersect with the floor beams at nodes every seven levels.

“There has been a huge effort to develop [node] details,” says Eley. Using Tekla Structures software, the designers worked with steel subcontractor William Hare Structural Engineers Ltd., Bury, to develop buildable nodes. Shop fabrication will allow the nodes to be welded, rather than bolted, for increased strength, says Eley. “We took the bolted connections away from the joints,” he says.

Weighing a maximum of 30 tonnes each, the nodes will be up to 6 m tall and 3 m wide. Large threaded bolts, up to 7.6 cm in diameter, will connect ends of the nodes' arms to the rest of the building frame. To transfer the large bolt forces, box sections will be welded into the ends of the abutting I-section steelwork. These internally stiffened bolt boxes will be about 50 cm long.

British Land started foundation work on the Leadenhall Street building in 2007, with Bovis Lend Lease Ltd., London, as its construction manager. To accelerate construction, the previous medium-rise building was demolished concurrently on-site, with a large crash deck protecting construction workers below.

“We were getting on with procurement of the project as a whole when the credit crunch came along,” says White.

With about half the piling done and the basement box built, British Land terminated contracts and mothballed the site in spring 2008. Early last year, the developer negotiated a joint-venture agreement to share continuing development of the project with Oxford. It also re-engaged the original design team but not Bovis. British Land had developed the project sufficiently to secure robust construction bids and no longer felt the need for a construction manager, says White.

Chinese firm bidding for top Cheesegrater job
13 May 2011 | By Iain Withers

Yuanda wants its first UK skyscraper job

Chinese skyscraper specialist Yuanda is stalking a prestigious job on British Land’s Cheesegrater tower in London.

The bid by the cladding contractor would be its first UK skyscraper job.

If successful the Chinese cladding contractor would usurp long-term favourites for the job, Germany-based Gartner.

Gartner was appointed on the Cheesegrater in 2007 but was dropped when British Land shelved the scheme because of the recession.

Building understands Gartner and Yuanda have submitted tenders to the four contractors bidding for the main contractor role - Mace, Skanska, Sir Robert McAlpine and Laing O’Rourke.

The four contractors submitted their bids for the design and build job last Friday and a winner is expected to be announced in the first week of August.

However, one source close to the project said not all four contractors had incorporated the Chinese contractor’s tender into their bids to British Land.

Yuanda completed its first major job in the UK last year on the cladding for the Park Plaza hotel near Westminster Bridge.

It has also completed a number of other mid-sized contracts, and is currently working on a mixed-used development in Snow Hill in Birmingham and a Thames Gateway project.

Yuanda is the second largest curtain wall contractor in the world and has worked on skyscrapers in the USA, Australia and Middle East as well as on several of the 2008 Beijing Olympic stadiums.

Cormac MacCrann, executive director of Canary Wharf Contractors, said that manufacturing capability meant cladding was one of the main areas where Chinese contractors could compete in the UK.

“There are many Asian cladding contractors that would like to work here. There’s not much competition for major cladding projects - you’ve only got a small number of companies.

“It’s the one area where Chinese companies with their manufacturing capabilities can compete.”

Some nicknames are cool. Others will never catch on like Cheesegrater (at least I hope so).

It's been announced today that 122 Leadenhall has secured Aon as a tenant, they will take almost a third of the building. No going back for this now. This building is one of few in London that could compete with the Shard for the city's best designed skyscraper.

Cheese rush: City leaps at vacant space

A dash for office space among some of the City's major players was expected today as insurer Aon agreed to lease nearly a third of British Land's 47-storey Cheesegrater skyscraper



Des res: Aon has agreed to let out one third of the Cheesegrater

Aon - which has long been linked with the £340 million building in Leadenhall Street next to the Richard Rogers-designed Lloyd's of London building in Lime Street - has agreed heads of terms for 191,000 square feet when the tower is completed in 2014. Aon, at present based in nearby Devonshire Square, also has options over another 85,000 square feet.

The firm is one of several players, including fund manager Schroders and Spain's Santander, on the hunt for space but among the first to have made a commitment. Aon is thought to have paid around £55 per square foot although British Land might hold off on letting the remaining space to take advantage of rising City rents.

Liberum Capital analyst Daniel Horwood said: "The future supply of large-scale space for pre-leasing is limited, visible to potential occupiers and they are all aware of each others' requirements.

"Activity is often characterised like 'dominoes' - after periods of inactivity, once one occupier commits the others all take note."

In a separate deal, the West End's Marble Arch Tower overlooking Hyde Park changed hands for £80 million today as property investment firm Almacantar bought the 21-storey building from Orchard Street Investment Management. It is the firm's third major deal of the year after buying the Centrepoint building and being chosen to redevelop Lord's Cricket Ground in north London

They're doing a good job at embedding the nickname into people minds.

Excellent news today. I will look forward to watching the Leadenhall Building rise
