The first presentation at the BIM breakfast held in early February was by Vladimir Bazhenov from the company VTM Dorproekt, which designs road infrastructure: highways, pedestrian crossings, overpasses, bridges, etc.

Reconstruction of a street in a city with a population of over a million
Project Features
Reconstruction of Solikamskaya Street in Perm: what made this project stand out? A length of 10 km in a densely populated city, dozens of junctions, about a hundred kilometers of reconstructed utility lines, two reconstructed bridges and an overpass over the railway.
Vladimir noted separately that any major road project begins with mathematical modeling of traffic flows. He presented to all visitors of the BIM breakfast a macromodel of the city of Perm, created, among other things, thanks to dozens of students who assessed traffic at checkpoints. Based on this array of data, VTM Dorproekt specialists built a forecast of traffic flows. As Vladimir admitted, as a result, they realized that the reconstruction of even a separate section of the road affects the traffic of the entire city. He also stated that the development of such a model is simply necessary for the correct design of roads.
Tools used
Several software tools were used to create the digital information model: the road part was made in TOPOMATIC Robur, IndorCAD and partially Civil 3D. The consolidated model was assembled in Nawisworks 2020, and artificial structures were created in Tekla Structures 2020.
Then Vladimir Bazhenov told how such programs as Plaxis and midas Civil were used for calculating structures and solving geotechnical problems, noting that without calculation models it is impossible to obtain adequate technical solutions for artificial structures, for a road, for pipes and even for lighting poles. Especially if the linear object is located in complex geological conditions.
Approach to a major city
Some construction industry experts may ask: what is difficult about building a road? After all, it is not an industrial building with a dozen different production lines. As an answer, Vladimir gives an example of a linear facility project near the city of Podolsk:
"We simply "turn" the city project inside out and see that it is always a large number of utility lines. And each utility line has its own balance holder, who has its own technical conditions and its own vision. They all need to be connected to each other so that there are no intersections, much less the impossibility of placing the facility."
How projects live for years
The project for the construction of a road, noise barriers and an overpass in the city of Dedovsk was created in VTM Dorproekt back in 2016. The overpass model was created using Tekla. And now, several years after the commissioning of the facility, the Ministry of Transport of the Moscow Region has a requirement to build an overpass instead of the liquidated ground one.
The designers of VTM Dorproekt took the project developed in 2016, received the executive documentation, brought the design model of the overpass to the executive one and placed the overpass in it.

Final words
Vladimir Bazhenov concluded his speech by enthusiastically noting how the consistent use of information modeling in the past has been beneficial in working on current projects. He also expressed hope that in the future there will be more information models that will be suitable for use in conjunction with several projects or even related companies.
