"by stumping £74m for a three-coat paint job similar to that used on oil rigs and which will last for up to 40 years."

So how much does it cost for a few guys, couple tins of paint and a brush? Surely not £74m over 40 years!

Confused on the business case for this one! :S

Can they do that paint in Toyota code 8G2 so I can rid my 1992 Carina II of it's rust and slap some of it on her?

2.4 million man hours of paint and they still haven't finished. Bloody consultants.

Mines the hi-vis jacket.

£74m is only a 1000th of what the Labour Government have stolen from its tax payers to bung into Northern Rock.

Unfortunately, it looks like Balfour Beattie are using the urban legend to advertise theirselves.

It's totally untrue that the Forth bridge was painted continually. That would be a logistical nightmare.

The frequency of the trains and the amount of safety equipment required to do such a job makes it a very slow process. But if they did do that, you would never see the bridge without tonnes and tonnes of scaffold hanging off of it.

True, there may have been frequent patchwork over the years, but its first big paint job since the day it went up was in the early 90's.

I know, I was there. I worked for the company that did that job.

...over 6 years? I'm pretty sure there's only 52,560 hours in six years. If your working day averages 8 hours, and you don't work on Sundays, then there's only around 15,000 working hours in six years. That means 2.4 million working hours is nearly 960 working years. So by my calculations they were at it for 842 years before the bridge was even completed! I _suppose_ they could have meant "man hours". In that case they had an average of just over 159 and four fifths of a person working on it at any one time...

in the same way that broadband is measured in "up to" units as well? Can we expect therefore that if the bridge is busy, it will be capped to maybe 2 years lifespan?

The powers that be should listen to Tom Stoppard's "Albert's Bridge" before embarking on such a strategy. It will avert disaster I tells ya.

Considering the Surface Area of the bridge is estimated at around 45 Acres I dont think that they would get very far with a few tins of paint and a solitary brush.

There is obviously a business model for this!

What, only £1.85m per year, not taking into account inflation? It's easily more than that. More than five times as much, in fact. See http://news.bbc.co.uk/2/low/uk_news/scotland/2808567.stm

...I hope that the first is a proper undercoat this time, and that they prime the surface properly before they start. I'd have done it for £300, 20 Bensons and a cuppa char. I quoted for that Channel Tunnel too back in the 80s but got turned down, even though I gave them a discount on 2x 26mile RSJs.

The 2.4million hours quoted in the post would have already cost somewhere in the region of £43m for labour alone and that was just for a period of 6 years. Another 34 on top of that plus inflation....well you do the math.

I happen to know that a skilled tradesman (which im guessing they would be to work over a bridge...could you see a chav in his burberry hat hanging off the forth? you might want to but that's not the point) are charged at around £18 per hour...about 1/3 of which they actually get paid (if they're lucky).

So financially it does make sense, perhaps the saving can help pay for Northern Rock...you know until it folds and we have to bail it out with our taxes.

Nice to see that Yahoo ran the story but with a picture of the Forth Road Bridge

If they have been painting for 100 years but the paint only lasts 40 years then the paint at one end of the bridge should have had the next repaint started 60 years ago surely?

If the bridge is 100 miles long and it took you a year to do a mile you'd only get 40 miles in before you had to start painting the first mile again.

So you get a second team in who start at the beginning and the first team does the next 40 miles.

The first team is now at 80 miles and the second team is at 40 so you need a third team to start the first mile again.

Now it gets tricky see because the first team can do the last 20 miles and the first 20 miles and the second team is at 80 and the third is at 40

I'll just get my coat and go now....

Actually it's not quite as simple as "a few guys, couple tins of paint and a brush". You have to remember, the bridge is over water, it's a long way up and the wind blows right up yer kilt! It's a real swine if you climb all the way out and then realise you to need to take a p***

As someone who has travelled over the road bridge a few times, I can assure you that anyone who is crazy enough to climb up and paint those things earns their pay.

There is a huge surface area (I estimate 6.0 sq Kilometre for 1 coat and at 30sq m per tin around 200,000 tins, but I could be miles out). I doubt that there is any single component small enough to be painted with a single tin of paint.

You can't just apply with a brush - the wind would blast it off before the paint had dried. Apart from that, it rains occasionally!

Well, if it's anything like the usual with these civil engineering contractors, it'll be done in 2020, cost 10x the original quote and three bolts will be missing at the end of it - resulting total collapse whilst a passenger train is crossing... Of course it'll all be the fault of the little cheese sandwich eating foreman whose name no-one will be able to remember.

Paris 'cos she's wondering what happend to the first, second and third bridges!

Only 53 "Ambitions"

Furthermore, Seán, there are continuously updated webcams pointed at a variety of interesting struts and joins, so the three-layer paint process can be inspected online by the public as the sunlight-accelerated solidification process gets underway. I hear it's fascinating.

Train-spotting has nothing on this.

Sorry to be boring, but there was a programme about it a while back and this time the process of repainting is much more than just painting over the top. Sections of the bridge are carefully sealed against the elements, old paint is shot blasted to bare metal and the metal is primed asap with a decent (etching?) primer with corrosion protection - I was told once by a shotblaster (person) that bare steel starts to oxidise quickly once being exposed to air and getting the primer on asap is important.

The primer is cheked with some sort of handheld scanning device to ensure it has coated/stuck/taken properly to the metal else it gets blasted off and they start again that area again.

Hopefully this will last or they can build a new one in stainless (if there is that much chromium around...)

I wasn't too impressed by the discussion til I saw a picture of this beast.

Yikes.....

It takes so long because you get to the top of ladder, splash a bit of paint about then your can's empty, so you have climb back down to the bottom, pop round to B & Q, but they clean out of that shade, so you have to start again with a different colour.

I tell you, it's like painting the forth bridge this is...

So in 2013 , the Brits will have to create a new song about a non London bridge 'all falling down' !

I'm sure your family in St Queensferry can see the Fourth Bridge from their house, but this story is about the Forth Bridge, which is more easily seen from South Queensferry. :-)

"It's the bloody Fourth Bridge. There is no structure named the Fourth Rail Bridge. Why would they have called it the Fourth Rail bridge when that was the only bridge over it at this point at that time?"

Um - not being from there...

BUT BEING ABLE TO READ....

http://en.wikipedia.org/wiki/Forth_Rail_Bridge

http://en.wikipedia.org/wiki/Forth_Road_Bridge

I would say that there are both a 'rail' and a 'road' bridge...

PH because I think that even she speaks English...

They don't make 'em to last like that anymore. If you haven't seen the bridge, I suggest you make the trip. Amazing!

It takes 100 years to paint, but the paint only lasts for 40 years?.

Paris, because she's had a brush with the law.

It's more usually called 'The Forth Bridge' locally.

Remember from 1890 till the mid-sixties it was the only bridge at this point - if you wanted to get your car across, you used the ferry...!

The only time here (Edinburgh and Fife) it's referred to as 'The Forth Rail Bridge' is on traffic reports, when they have to differentiate between the two.

Here's one of my pics of the bridge, showing how long even the support viaducts are...

for our American cousins. When a new gas loading terminal was being built on the Forth near to the bridge back in the early eighties, one yank "engineer" was apparently giving the standard "We built this, we built that, bigger, better yadda, yadda, yadda" speech to some of the locals. One large Fifer, puts his arm around the yank and pointing at the Forth Bridge says "See that, well WE built that while you were still fighting the f**king indians!" Bragging session OVER!

The big difference in the paint job this time, unlike the last 'high-tech' paint job, is that they're taking the structure (cast iron) back to bare metal, not just slapping it over 100 years worth of 'red lead' paint. When they did that, back in the 90's (correct me if I'm wrong Mark M!), they sealed in all the moisture and the bridge started rotting under the paint, with some fairly large bits falling off!!

As for the 'lifespan' of this latest paint job, I'll just wait and see.

One question though, is the 20 years being measured from when the first sections were completed, or the last, as there'll be about a 10 year period between the two?

Mine is the "Craig & Rose" red one!

This reminds me of when employees of British Layland all had Maxi Orange bathrooms!!

Will the employees painting the bridge all have 40 year proof painted houses??

LOL

I feel every day we slip into an era of mindless squabbles over cash. When the Luddites where in the factories and smashed those darn machines, making weaving the first job to take away manual labor. Then years later motor companies really ditch massive numbers of workers in favor of robots to carry out the work. Now many workers who spend decades of whats become a national tradition now put out by wonder paint. I agree mechanical weaving has made better clothes, and robots do build better cars, which are safer etc. But its the same old same old one day your employer pats you on the back and says good job and then feels notes in his pocket, tomorrow that same employer pats you on the back and says "good job but i have to let you go". How soon will it be before we live in a totally automated world. Visions of 1984 that film of The Final BIG BROTHER spring to mind. EEEeeeekk

PS take Big Brothers (the CH4 show) and Princess Nikki, now you see how manual labor is an extra hassle for some folk...

I think people should think before they comment, 160 workers, working at approx 15,000 hours over 6 years does infact equal 2.4 million man hours. So please do pull your heads out of the clouds and do the math.

That, sir, is a great photograph.

Well done that man.

The paint relies upon a "sunlight-accelerated solidification process".

In Scotland.

Isn't there a rather fundamental flaw in this plan?

@Liam O'Flaherty

No.

They make it but won't retail it. It would screw up the DIY paint business model.

From what I remember of recent history, N.R. are not exactlyTHE best at maintenance are they....

Better check thats not Dulux emulsion hadn't we boys :-)

Memo to self: Dont travel beyong Edinburgh by rail, or else take life jacket.......

Just wrap the whole damn thing in plastic and apply heat. Turns it into a nice water proof tunnel plus the tension of the plastic will strengthen the bridge and keep any pieces from falling off.

Hey! At least let me get my coat before you rush me out the door!
