Budimex, in consortium with Strabag, has built a 12-kilometre section of the S14 expressway, from the Łódź Lublinek junction to the Łódź Teofilów junction, which is the southern section of the western bypass of Łódź, in the “design and build” system. As part of the investment, 4 road junctions, 17 engineering structures and 10 culverts were built. The water supply network, sanitary sewage system, medium and high pressure gas network (length 5.7 km), LV, MV and HV power lines and teletechnical networks were also rebuilt. The biggest engineering challenge was to remove the collision of the new transmission networks in the right-of-way with the previously existing underground installations: water, energy, gas. At key moments, 220 units of construction equipment and nearly half a thousand people worked on the construction site.
