Pulkovskoe Shosse and Dunayskiy Prospekt. One of the most congested intersections in the city will soon become at two-layer one. 11,000 tons of metal - that's how much it took to build a new fly-over at the city's landmark highway. Despite heavy presence of construction gear, only the assembler is able to piece all parts of metal into one solid body. Vitaliy Alekseev is a chief assembler in the crew, which is building a new object in the city, block by block, like a constructor toy.

That's right. You need to make it straighter, Vova. 

Yes yes yes. 

Is the protective layer OK? 

Well, go on if it's OK.

Even if you're driving past, it's always pleasant to say I worked here. That's about any building.

Stop, stop. We should make it higher. Don't need it? Is that OK? Make sure you don't hit the bolt off. The crane!

Pulkovskoe Shosse and Dunayskiy Prospekt. One of the most congested intersections in the city will soon become at two-layer one. 11,000 tons of metal - that's how much it took to build a new fly-over at the city's landmark highway. Despite heavy presence of construction gear, only the assembler is able to piece all parts of metal into one solid body. Vitaliy Alekseev is a chief assembler in the crew, which is building a new object in the city, block by block, like a constructor toy.

Considering that the whole intersection, in principle, is made of metallic parts-it turns out that the assembling, the joining together of elements lies on the shoulders of an ordinary assembler.

This safety measure is number one in my life. The safety belt. I simply have no right to work without it.

Vitaliy Alekseev, assembler of metallic and concrete parts at “Pylon” JSC: “An assembler must monitor every lifting of a cargo, every turn of a cargo, everything. Because. Well, we don't have a lot of time to relax. We are almost always tense. Because everywhere there on tractors, dear, cars. You have to be very attentive, be very aware.

The plates must all be well-sanded before installation, so that there's no rust or anything. This is how we connect every bolt junction. Here, have one. So you take the bolt and i connect it, ok?

Yes, yes, yes.

Well OK.

Alexey Orlov, work supervisor at “Pylon” JSC: “Choosing the right gear for unloading - you need an assembler. Attaching the slings - also need an assembler. So, you cannot do anything without assemblers - starting with the usual unloading of a beam.

Vitaliy Alekseev, assembler of metallic and concrete parts at “Pylon” JSC: “If I cannot play I guitar or sing songs, not every person similarly can be an assembler. First and foremost, you have to fall in love with this profession.

Before building the exit at the intersection of Pulkovskiy and Dunayskiy, specialists counted the passing traffic. According to the norms, a new level is necessary if there are more than 4000 cars per hour. It turned out that the intersection was congested two-fold - 8000 cars every hour.

Olga Shvaika, head of construction and reconstruction department at St. Petersburg’s transport infrastructure development committee: “Considering the intensity which existed in that part when we made the decision to blueprint and construct, we just could not allow the traffic to stand still. That's why this exit will act as a pathway from the south, also we will liquidate the time losses from the vehicles standing still. We are unloading the inter-district transport flows, which is very important for the city's transport infrastructure.

This fly-over is one of the objects which are necessary for St. Petersburg holding the 2018 World Cup. In order for guests of the city to reach the central part from the airport, not spending a lot of time in traffic jams, at six-lane pathway, 1321 meters long, was built over Pulkovskoe Shosse. It has 21 exits and five underground pedestrian crossings.

Vitaliy Alekseev, assembler of metallic and concrete parts at “Pylon” JSC: “This grandiose junction from Predportovyi and there - and from Dunaiskiy and Moskovskiy - will certainly help. There will be less traffic jams, I think.

This is the foundation for the wall. The wall will be builthere later, and in the middle there will be sand, so this will serve as the continuation of the bridge with an exit further on. So every reinforcement is made by an assembler. Is that right, Vova? It is not an easy task to build a bridge. Every junction must be put together. We used to weld it, but now it has been banned - because corrosion is the eventual result ofwelding. They banned welding the reinforced parts, so now we can only join those together with brass threads. We split it in half, take it around a reinforced junction, crisscrossed, connect it to a hook, and bend it like this. Now all three are together. And tighten the string. That's it. It is better than welding.

Vitaliy Petrovich is one of those assemblers, not only urges his entire crew to work hard, but also encourages other managers. With him nearby, even the laziest workers work hard. So we don't have the lazy ones here.

If you don't have a team, then you won't be able to do a thing. Everyone understands me. I have the first chain, second, third. I walk over to a senior and tell him what to do. Tomorrow, for instance, its concrete. We have to get everything ready. You have to be friendly with people, talk to them, understand every person. One person needs to be praised, the other one needs directions. You have to know approach to every single person.

What are you thinking of? To connect it and reinforce it as quickly as possible, that's it, so that cars can start driving here quicker, and there would be no traffic jams in the city.

St. Petersburg first saw the necessity of flyovers when initial railroads were built. In 1895 the first beam flyover of 60-meter length was built over a railroad connecting St. Petersburg and Moscow - where nowadays Prospekt Alexandrovskoy Fermy is situated. The first bridges over other roads were built due to safety concerns, but today those are built because of growing traffic.

The active traffic flow has to be considered in the process of construction. That's why while the new flyover at PulkovskoeShosse is being built, traffic is only partially suspended. The bridge itself-weighing 750 tons-was first assembled on the side, and then installed over the highway.

When we got down to construction, we worked out thescheme of traffic flow, which entailed partial suspension of traffic - including on Pulkovskoe Shosse. When we were installing the pillars - which had to be in very close proximity to the highway - we were forced to partially suspend the traffic. But those were short-term suspensions. We never completely shut down Pulkovskoe Shosse. The fullshut down was not even considered during the blueprinting stage.

Another peculiarity of the flyover junction is the part with anchor roosts. Four symmetrical pylons - 30-meter high -were installed for it. According to architects, this part will not only support the flyover, but will also make the southernentrance to St. Petersburg prettier.

Konstantin Bobkov, head of construction at “Pylon” JSC: “We have built the flyover at Pulkovskoe Shosse, it's a very long one, so we could not build pillars made of concrete right in the middle of the road. That's why we used the anchor roost system. Put two pylons and connect them with beams, which hold the middle of the flyover.

Alexey Orlov, work supervisor at “Pylon” JSC: “You can say this is the arc into the city, a portal to St. Petersburg. And this part with anchor roosts will become something of a  gateway, welcoming all guests into our city.

Preparations for the installation of the anchor roosts system is also something assemblers are responsible for. The connecting element, the anchor, is put into a so-called shell, situated inside the pylon. Beams are then connected to every hole in the anchor. Depending on the load, there can be between 19 and 39 of those.

This shell will house 19 anchor roosts. And from that side.You did assemble it from that other side, Igor? Here, the big anchor is on its way. We will now assemble it into the shell - right where it belongs. Do not screw the bolt. You have to correct those things. See, you inserted them wrongly.

While the anchor roost system has not yet been installed, temporary foundations are supporting the flyover at PulovskoyeShosse. Only after anchor roosts are installed will the bridge see tarmac laid on it.

These spikes serve to connect the reinforced parts and the concrete. These are Nelson’s reinforcements-it is a parallel beam. It connects two main beams with bold junctions. Everything is connected through these bolts and that's it. Then we clean it, put reinforcements around it, and through it as well. After which we pour concrete, as well as waterproofing, and then liquid tarmac - 6 cm thick. After which we put the road tarmac for the cars to drive on-eight or ten cm thick, I don't remember exactly.

It is much easier to build the new, than renovating the old. Although renovating work is much more interesting - simply because today there are no such projects as our fathers and grandfathers had. The old bridges - Dvortsovyi and Troutskiy - were built using rivets. You won't see rivets like that these days-only bolts and junctions, that's it. While in the old days they build everything using rivets. And applied force to it too. When we were replacing all this - cutting out vintage parts - it hurt inside.

In 15 years working as an assembler, Vitaliy Alekseev not only participated in reconstruction of St. Petersburg's oldest bridges, but also in building the Western Speed Diameter, Sofiyskayatransport junction, a fly-over at Prospekt Kosygina. But his dream project is still somewhere in the future.

Vitaliy Alekseev, assembler of metallic and concrete parts at “Pylon” JSC:  “I would also want, maybe, to build and a newbridge over Neva. I have indeed taking part in building the 19th anchor roost bridge, but I have not built anything over the river yet. And this is something I would like to do.

Dreaming of new projects, while making the city better every day. The Southern gates of St. Petersburg. We are the ones deciding what to bring here or what to take from here. We are building our city together. Every single one of us is building St. Petersburg.

Vitaliy Alekseev, assembler of metallic and concrete parts at “Pylon” JSC: “If we do not invest a part of ourselves into our work, we will not achieve anything in this life. Only if every person tries hard, will manage to build something together.
