Will Some Of The New Buildings For Heathrow Be Built In Scotland?

It’s all explained in this article on the Offsite Hub website, which is entitled Heathrow To Offer Offsite Hubs To Other Mega Projects.

This is the first two paragrahs.

Airport says schemes such as HS2 and Hinkley could make use of planned offsite manufacturing hubs

Heathrow Airport has said it hopes its idea for a series of offsite manufacturing hubs to help with its £16bn expansion plans will be used by other major projects, including the new nuclear power station at Hinkley and the HS2 railway.

Sounds a good idea to me.

A few other points.

  • Offsite accounts for 10% of the construction industry.
  • Heathrow are aiming for between 25% and 40%.
  • It will reduce the peak on-site workforce at Heathrow.
  • Offsite was safer, cleaner and less weather dependent.
  • Four hubs are plans, with one definitely in Scxotland.

A few months ago I talked to one of the managers building Custom House station, which was largely built offsite in Sheffield.

He told me, that the quality was so much better, than if it had been built traditionally.

The quality certainly wasn’t traditional pre-fab either.

Could this be part of the solution to our housing crisis?

Should This Be Done On More Building Projects?

Buckingham Group are building the new West Hampstead station on the North London Line.

This picture was taken of the architect’s layout drawing of the new station, that was fixed to the hoardings.

I wasn’t the only person giving it a good study.

I think it is a good way to inform the public.

How To Build Railway Stations

With all the troubles caused by the failure of Carillion, it is good to report on a company, that is providing new and improved railway infrastructuresubstantially  on time and on budget.

This article on Rail Engineer is entitled VolkerFitzpatrick: Upgrading Stations.

This is the first two paragraphs.

With Network Rail’s comprehensive Railway Upgrade Plan well underway and the modernisation of Britain’s railways firmly in the spotlight, there is a growing need and expectation for first-class stations and infrastructure to accommodate growing numbers of passengers nationwide.

One business with a huge role in the modernisation programme has developed a reputation as an exceptional multi-disciplinary contractor, with extensive capabilities in civil engineering, building and rail, meeting the demands of a wide range of clients across multiple disciplines. It is this consolidated approach that has helped VolkerFitzpatrick deliver several high-profile UK railway station schemes in the last 10 years.

The article then goes on to describe how the company tackled the following stations.

It then goes on to detail the company’s omvolvement in the Lea Valley Improvement Program, which will deliver new stations at Tottenham Hale, Northumberland Park and Meridian Water.

Read the Rail |Engineer article, as it gives a good insight into design and construction.

How To 3D-Print Using Concrete!

All the 3D-printing I’ve seen has involved plastic, but Crossrail’s builders are using the technique to create complex shapes in concrete.

It’s all explained in this post on IanVisits, which is entitled How Crossrail Is Using 3D-Printing To Build Its Stations.

They don’t actually 3D-print the concrete, but a wax mould, that is then used to cast the actual piece required.

According to the post, the FreeFAB process has been used to create 1,400 unique moulds, which have then been used to create 36,000 different shaped concrete panels.

Ian’s post is a fascinating read and the mind boggles as to what will eventually produced using this technique.

Grayling On Crossrail 2

This is Chris Grayling’s thoughts on |Crossral 2 for this article in City AM.

I am a supporter of Crossrail 2 but given its price tag we have to ensure that we get this right. The mayor and I have agreed to work together on it over the coming months to develop plans that are as strong as possible, so that the public gets an affordable scheme that is fair to the UK taxpayer.

Following a successful outcome being reached I am keen to launch a fresh public consultation to help gather views to improve the scheme and clarify the position around the safeguarded route.

So perhaps, the line will get built after all.

Thoughts On The Tragedy At Grenfell Tower

As a family, C, myself and our three boys used to live in a tower block. Admittedly, Cromwell Tower was an upmarket tower in the Barbican. I wrote about the tower in Cromwell Tower.

Cromwell Tower was designed around a concrete core in a brutalist style in the 1960s, just like Grenfell Tower.

Cromwell Tower had a network of passages that allowed escape to the floors underneath. I suspect that Grenfell Tower had similar passages.

But there were differences.

  • Cromwell Tower had a higher standard of interior finish.
  • Every flat in Cromwell Tower has a wide airy balcony.
  • Cromwell Tower has no gas.
  • Cromwell Tower was designed for high net worth tenants, whereas Grenfell Tower was a Council block.

As both blocks were designed around the same time, I suspect that they were designed to the same set of regulations.

So why did Grenfell Tower catch fire?

These are possible reasons.

Gas

I don’t like gas, as one thing I remember from working at ICI in the 1960s, is that how powerful a gas explosion can be.

Naked gas flames also are a major cause of asthma, as they create oxides of nitrogen.

But if wee had had gas in Cromwell Tower and there had been a leak, the escape passages would have been an ideal way for the gas to spread through the tower.

For these and other reasons, I believe strongly, that all multiple occupancy housing should not be connected to a gas supply.

I’ve also heard that view from a Chief Fire Officer in Suffolk.

The Design And Execution Of The Upgrade

Was it done to high enough standards.

The Cladding

\Suspicion is falling on the cladding of the building.

Smoking

How friendly was the building to smokers?

Have we really learned the lessons of the past?

The Summerland Disaster

In 1971, over fifty people were killed in a fire on the Isle of Man in the Summerland Disaster. This is Wikipedia’s summary.

The Summerland disaster occurred when a fire spread through the Summerland leisure centre in Douglas on the Isle of Man on the night of 2 August 1973. Between fifty and fifty-three people were killed and eighty seriously injured

I know it wasn’t a tower block, but I think that there are common issues.

Under Background this is said.

Summerland was opened on 25 May 1971. It was a climate-controlled building covering 3.5 acres (1.4 ha) on Douglas’s waterfront, consisting of 50,000 sq ft (4,600 m2) of floor area at a cost of £2 million. The building’s hull and the interior were designed by two different architects—they did not match their planning to each other and thereby created a venue with significant fire risks that were only to become apparent later.

So did the architects of the upgrade do a proper job? Did they have any co-operation with the original architects.

The same Background section also says this.

Summerland was designed to accommodate up to 10,000 tourists and comprised a dance area, five floors of holiday games, restaurants and public bars. It was a 1960s concrete design incorporating advanced controlled internal climate, built with novel construction techniques using new plastic materials. The street frontage and part of the roof was clad in Oroglas, a transparent acrylic glass sheeting.

Note the use of Oroglas cladding, which is still made today.

At the time of the Summerland disaster, I was working at ICI Plastics, who made a similar acrylic sheet called Perspex. As I look around my kitchen, I see various applications of this or similar plastics.

In several places in one ICI chemical works, Perspex windows were used, as there was the occasional small explosion and you didn’t want to shower people in glass fragments.  But they were clearly marked Perspex Window – Fire Hazard.

So the problems of acrylic were clearly known at the time and yet, acrylic sheet was used to clad the building. One ICI Perspex expert told me, that Perspex shouldn’t be used to clad buildings.

So was the cladding itself a fire risk at Grenfell Tower because an inappropriate material was used, just as at Summerland?

Under Fire, this is said.

The fire started around 7:30 p.m. on 2 August 1973, and was caused by three boys who were smoking in a small, disused kiosk adjacent to the centre’s miniature golf course.

So was smoking, one of the causes of the fire, just as it was in the Summerland disaster?

We don’t seem to have learned much from the Summerland disaster.

Conclusion

I’m led back to gas being the cause of the original fire, as there is nothing energetic enough to cause such a fierce fire.

It is also stated in various media articles, that there were problems with the gas.

Heathrow Plan To Build Third Runway – On Stilts Over M25

This is the title of an article in the Business section of the Sunday Times.

Apparently, three viaducts would be built over the M25, with a wide one for the runway and two narrower ones for the taxi-ways.

Sounds fine by me!

I also feel that the technique of using stilts could be applied to build new housing and commercial properties over roads and railways.

Look at all that space over some city centre stations!

I Can Clearly See Through The Hackney Wick Subway

A couple of days and they’re really pushed on at Hackney Wick station.

It looks like after the May Bank Holiday, they may have opened up the subway for pedestrians, as barriers seem to be ready to create a walkway.

The Subway Is Finally Exposed

These pictures show the subway and a few other things at Hackney Wick station.

It looks to my untrained eye, that now, the builders can get on with putting in the stairs and lifts and then fit out the station ready for opening.

This visualisation shows how the station will look on completion.

Hackney Wick Station South Elevstion

I do hope they leave the approach to the station clear, as in the visualisation.
