A look at the huge HS2 viaducts located at the northern tip of the Delta junction, Curdworth, Sutton Coldfield. The River Tame West single-track viaduct is the first completed viaduct in the West Midlands.

00:00Daniel Wharton with the Express and Star, so as you can see around us we're standing

00:11inside of the HS2's Delta Junction viaduct which is currently being built.

00:18So we've obviously taken loads of photos, spoken to a few of the site managers around

00:22here.

00:23It's an absolutely impressive structure that obviously as you can see inside, you can see

00:27all the way down the bottom, there are currently press down there as well, the press media.

00:30But yeah, it's an absolutely fantastic structure, we were talking to them about the innovative

00:34technologies that was being developed and that's also been brought in to help construct

00:40this mammoth sized project with one of the most important being a safety structure, so

00:47like an innovative bit of safety technology which sees all the major equipment equipped

00:53with sensors that stop dangerous things from happening on site, so the minute they sense

00:59danger they all switch off and you can't override them.

01:01So it's an absolutely fantastic project that's using a lot of innovative technologies.

01:07But yeah, it's an absolutely fantastic thing to look into and it's quite a mammoth sized

01:13project.

01:14So we are going to walk on the River Thames single track, the first completed viaduct

01:18of the Precast Segmental Viaduct at the north of the Delta Junction.

01:22Yeah, so if you just talk a little bit about, just describe a little bit about what the

01:26machinery that we can see in front of us, around us, if you don't mind.

01:29So yes, we have the mast and tool crane which allow us to build our Precast Segmental Viaduct

01:34and it's a piece of kit that is efficient and versatile so we can cover all the specificity

01:42and constraints of our project.

01:45That's fantastic.

01:46So obviously there's a lot of, we were talking a little bit over there about innovation,

01:50you described quite a few innovative techniques that's come up from this, like we were talking

01:53about VR.

01:54I believe these, did you say these are tailor made as well, these machines here?

01:59That's tailor made for the project, so it's been designed and built just for this project,

02:04but within our company we use them in the past.

02:07And yes, as I was mentioning earlier, we use the lesson learned and the experience from

02:11the past to redesign and improve the quality and the efficiency of the tool.

02:16That's fantastic.

02:17So what other innovative techniques are being used on site if we can talk about that?

02:21So the main, there is many innovative here on this project, many, but one of the most

02:27best ones is the VR training, so we have developed a virtual training which, so before the operative

02:34come and walk inside at height, we sat them in the meeting room and they can literally

02:41see the entire environment with the height of the mast, the two-wall crane, all the

02:45plants surrounding them, but inside the safe meeting room.

02:49That's one of the innovations, so when they arrive on site, they already know what to

02:53expect.

02:54And so what's the main difficulty with handling a job of this size?

03:00So the main difficulty I would say is the environment itself, so there is a lot of constraints,

03:06as we were explaining, there is the river frame, there is the minors conduit, there

03:09is two railway, we have 400 kV overhead cable, there is the Lichfield road, there is the

03:14motorway, the M42, M6, and all of that create us a big challenge because we have a lot of

03:21interface and we have a lot of interface.

03:25Absolutely, and obviously it's one hell of a thing to plan, isn't it really, I suppose,

03:30you know, it's a gigantic thing to plan.
