It was very noisy at the site today, lots of people looking around wondering what all the noise is. Not much difference since last update.

well thats pretty cool lol.

the thing which i think is also cool is the fact that after they are built london will have 3 clusters. and others dotted around, the only other city i can think about which has more then 1 cluster is NewYork lower manhatten and mid manhatten or where the ESB is.

But there are loads of cities with more than one cluster.... Hong Kong, Shanghai, Tokyo, Istanbul to name just four that immediately come to mind.

This is a rendering I haven't seen before. Includes Heron Plaza, Heron Tower, 100 Bishopsgate and the Pinnacle. It creates a "wall" effect, but I think it looks quite cool -

The height of office-space sophistication

The Pinnacle in the City of London poses challenges in demolition, core construction, piling and its glass 'skirt'

Project: The Pinnacle, London
Client: Pinnacle One
Project manager: Mace
Piling contractor: Bachy Soletanche
Cost: Estimated at £1.2 billion
Completion date: August 2011





There is no doubting the scale of the Pinnacle tower office development. The scheme on Bishopsgate in the City of London is huge.

When finished it will be the tallest tower in the City of London. With estimates of the total project cost reaching a dizzying £1.2 billion, it will be one of the most expensive, complicated, projects attempted in London.

Everything about it is impressively big - from its 300 m height to its 10,000 sq m of floor space, from its 6,000 identical glass panels to the cast of thousands working on the ground.

The Pinnacle's proposed height marks the City's build ceiling. Any higher, and it would represent a danger to planes flying into City Airport.

Such a distinctive building creates a set of distinctive problems - the difficulties of working at extreme height on a congested site, to create a building with 65 individually designed floors, in the heart of one of the world's biggest cities, served by narrow medieval roads.

And all without making any noise for most of the day, in order to please neighbours in nearby flats and offices.

Yet despite these problems, the Pinnacle project appears to be rolling ahead at considerable pace.

The project is currently at the demolition stage, which is expected to carry on until February 2008 when work begins on the superstructure.

The site was previously occupied by two office buildings, the latter of which has been found to contain about twice as much concrete as anyone suspected - all of which had to be removed without making any noise.

"It's right next to insurance company Hiscox's building so we're having to be extremely careful," says Mace's project manager Jeremy Wilkins.

"It's an extremely congested area with a lot of influential people. But the City of London is on our side. The powers that be in this area want the Pinnacle to be built, and that makes a big difference."

Given the building's height, the piling phase is also set to be among the biggest such jobs ever undertaken in the UK.

Contractors Bachy Soletanche will sink 60 main 2.4 m piles, each reaching 60 m deep, through 50 million years of rock to the Thanet Sands beneath.

Each pile will need 13 hours of continuous concrete pouring to fill, but the Pinnacle team is confident that the job can be done within noise limits.





Medieval approach roads

Another major issue is access - not just for piling rigs, but for all site vehicles. The site is served only by the ancient and narrow roads of Bishopsgate and Undershaft, and these must also support other large construction projects.

"We've limited our access mostly to Bishopsgate to allow other schemes access to space on Undershaft.

"But the road is one of the busiest in the city, so that creates its own problems," Mr Wilkins says.

"Access is a nightmare, especially because there are so many other building projects going on around us.

"It's not just us who are building here, other people also need to access the site. Companies working around here have issues with too many vehicles coming and going," he adds.

To cope with this, the team is storing much of the material at staging posts on the edge of London, with the aim of bringing it to the site at the last possible moment.

It is because of issues of space that the decision was taken to construct the building's core - containing the lifts, cables, stairways and storage rooms - from concrete, with a steel outer frame.

But the Pinnacle's innovative design has made designing the core a challenge. Each floor is different. There is no set pattern that can be repeated.

"That means the core has had to narrow through each level - so it gets more difficult to fit in the cables, lift shafts and ductwork and pipework as the building rises," says Mr Wilkins.

The Pinnacle was designed with a steel core, partly to reduce this problem, but the project team decided on concrete because its greater rigidity provides better support for the four tower cranes which will be brought onto the site and winched upwards as the building grows.

"Our plan is to use a slip-form method which is adjusted at each level," Mr Wilkins says. "But we haven't ironed out the details; we're looking to the successful subcontractors to provide a lot of input.

"They will be involved in decisions on the mix and strength of the concrete. Those decisions are still under discussion."

At 6,000 sq m the tight site has little spare room for cranes. They will have to be removed well before the site is completed, to make room for the neighbouring 15-storey building which will provide a service facility and separate entrance to the lower floors - known on site as the Sliver - and for the innovative glass 'skirt' which will encircle the Pinnacle around its third storey.





Wrapped in a skirt

The skirt - consisting of thousands of glass panels Đ will reach out 10 m, covering almost the entire site and is intended to protect those at street level from the downdrafts generated by the Pinnacle and other high-rise buildings.

Experts from Arup have worked for months modelling different wind conditions around the tower, assessing the shape of the skirt and the size and arrangement of the panes, to work out how the air-flow will best be broken up.

However, the wind watchers are also putting their faith in a more low-tech solution - trees - an idea that will also add to the building's green credentials.

The site has several inbuilt sustainability features. Giant photovoltaic cells will produce 10 per cent of the building's energy and surround the top of the tower in a maintenance collar wide enough to walk around. And the inner panes of the triple glazed windows will open to allow natural ventilation.





Up in the clouds

The higher the floor, the more exclusive the office, the more difficult the build. Of the Pinnacle's 65 floors, three will be sub-ground basements, with space for storage and parking. Though there will be space for 600 bikes there will only be bays for six cars.

At ground level it will feature two lobbies, one in the Sliver and another in the main building, with access to a selection of lifts, depending on the height at which you work. A new pedestrian thoroughfare and arcade of shops will pass between the Sliver and the Pinnacle, running from Bishopsgate to Undershaft and through to St Mary Axe.

Above that, 10 floors of open-plan office space, each around 2,700 sq m, should be ready and pre-let well before the completion of the building.

Above that, office floors get ever-smaller and more exclusive, until by the time they reach floor 47, every office comes equipped with its own balcony, with spectacular views.





Making way for the new

Demolition has been hampered all the way along by the concrete-heavy design of the original buildings.

"I don't know why there's so much concrete in there," says project manager Jeremy Wilkins. "But the building was originally built to house two banks, and they were probably quite security conscious.

"It was also partially rebuilt after bomb damage during the 1990s, which could have seen more concrete added. And an atrium was put in. That rebuild also led to more concrete."

The site team, including project managers Mace and demolition contractor Keltbray, looked at several methods of taking down the concrete silently, including injecting chemicals into the walls to dissolve the concrete from the inside. They settled on using diamond-tipped drills and saws to cut the concrete into small pieces.

Once it is cut into manageable pieces, it is shipped to Keltbray's East London base for recycling. However some pieces of concrete defied this tactic.

At the front of the building a single concrete bar, supporting the front of the atrium and weighing 250 tonnes, could not be demolished by conventional methods.

Instead, the site team cut the 15 m bar into 3 m sections, each of which was removed individually by a 31 m tower crane.

To do so, they had to close the enormously busy pedestrian thoroughfare of Bishopsgate entirely from midnight until 7 am, on Saturday 1 December – a move which took weeks of negotiation with the City of London.





TIMELINE TO COMPLETION

May 2007-Feb 2008 Demolition and piling

Feb 2008-Feb 2009 Substructure

Feb 2009-August 2011 Superstructure, early fit out on floors 1-10

August 2011 Superstructure complete; fit out begins on floors 11-62

"A verdict on whether demolition work can continue at the Pinnacle on Bishopsgate, in the City, is expected this week. Insurance firm Hiscox, whose building neighbours the Pinnacle, is seeking an injunction against developer Arab Investments and demolition subcontractor Keltbray over site vibrations."

i think they will let it get demolished it would be silly not to maybe they might change the hours to night time demolition who knows but the demolition shouldn't stop

If a planning permit has been granted involving demolition, conditions can be agreed, but the permit holder has the right to demolish and it is well understood that construction will cause some problems to adjacent owners - the issue is that the contractor should do all that is reasonable to mitigate problems including making necessary arrangements with adjacent owners, particularly if construction involves going onto their property for access, working space etc. However piling works during the day would likely be considered to be a reasonable need of a contractor, but it may be agreed to do works immediately adjacent to Hiscox at more limited hours.
