Che dire complimenti, 🎉🎊 ottima tecnica, qui avrebbero interrotto la linea ferroviaria per anni e poi avrebbero scavato e fatto tutto il resto... ovviamente li bisogna quantificare i costi aziendali di cantiere di costruzione e sovrapporli con i costi della azienda ferroviaria, aggiungendo i disagi dei viaggiatori... ma qui in Italia contano solo i costi delle aziende costruttici!!!

Being relatively local to Filton and Patchway, I've just commented on the Filton Bank Blockade time lapse and asked whether the forthcoming replacement of Gypsy Patch Lane bridge might also be getting similar treatment. In respect of the replacement of the Gypsy Patch Lane bridge, I have been told it is a requirement that the line, which is the main line to south Wales, can only be closed for a maximum of eleven days. In answer to the comment that what we see here was a very expensive way of building a bridge, I must assume that a similar constraint was placed on the work.

Further to my previous comment, I've been puzzled by the title of this video. as I believe it shows the construction of a new bridge to take the A4174 South Bristol Link Road under the Great Western Railway main line between Bristol and the south west. In this case, minimal closure time of the line would have been a primary requirement of the contract. This should answer once and for all the critical comment made about the expensive manner of construction.

12 months to make a simple tunnel

@jim2lane 3 жыл бұрын

Well, when you consider that they had to create the tunnel under an existing railway, and had to keep the amount of time that railway could be unusable to a minimum, which required them to build the new bridge in situ and then slide it over into place, and also perform all of this construction adjacent to a much older tunnel/bridge and not damage them - it really doesn't sound that simple in the end 😉

i couldn't work out what they were doing. after watching the whole thing it became obvious. then my brain started devising all the other ways this could have been done. moving all that dirt would have been a great percentage of the cost. if engineers spent more time on tools, or any time on tools, before graduating, they might have devised any of the better ways to do this job.

@vsvnrg3263 3 жыл бұрын

@@johnm2012 ,i had to watch it again to remind me why i made the comment. that massive amount of dirt that was moved in to provide a stable base for the slide-in indicates to me that there are going to be many different ways to do this while maintaining traffic on the lines. so i wouldn't do that slide-in bridge. how about a single section placed next to the line on whatever sort of temporary support after the abutments have been done. then a big dig out of one existing track and base just enough to slide or lift the new piece in. and another thing use bigger excavators. they move more dirt faster. i'd do the new bridge section in steel only. then put the new section of track straight on it. then do the other side. it sounds easy from my armchair. a useful piece of equipment that anyone who does this sort of stuff needs to know about is called a "non-intrusive crossover". they're made in scotland. its patented but i have reason to suspect it is a repackaged old idea probably not worthy of a patent. if the slide-in was to bugger up and couldn't be completed overnight then the "nic" could be used temporarily to maintain services. call it the plan b that every engineering job requires. but omg, all that dirt!

@xaiano794 5 жыл бұрын

it only took that long because they were having to build the bridge beneath an active railway line - it would probably cost 5 times less to simply shut down the line and dig the stretch out, you could likely have it built in a couple months, but because our rail network is so overcrowded we can't close a line like this for a couple of months so we instead have to build it like this.

@adelesexton5975 5 жыл бұрын

I agree. I saw them put a 4 lane freeway under an active railroad and they did not build a pile of dirt to do it. They dug under the tracks while temporarily supporting the tracks and then build the supporting bridges. No waste of adding dirt just to remove it again.

@@adelesexton5975 to install the temporary bridge structure underneath the tracks requires shutting down the tracks to do it, I don't think you realise how much traffic uses UK railroads - where in the US you're talking about 4-5 trains per day, in the UK it can be as many as 30-40 trains per hour on most main routes (and yes that's 2-track)

@@xaiano794 You also have to consider that the cost of shutting the railway and the lost revenue associated with it would likely cost more than the extra cost involved in a scheme like this. Cost, speed, quality, pick two. You can have a quality structure with minimal disturbance but it will be expensive. You can have a cheap, high quality structure but you'll have to shut the railway down for months. You can have a cheap, low disturbance structure but it will be low quality. People will complain In any situation. If you don't maintain a structure or add/improve infrastructure people complain. If you close down infrastructure to maintain or improve it people complain. If you find a way of maintaining or improving infrastructure with minimal interference people complain that It costs too much.

@catrachocolo 4 жыл бұрын

Here is your "more to the story": Do it the "traditional way" and you have to close down that railway line for weeks, if not months. This way you're down to a handful of days at most. And shutting down an important transport axis for an extended period of time is going to cost a lot more than the additional construction expenses. It is pretty simple, actually.
