Projektowanie i budowanie przy użyciu wirtualnych modeli (BIM)
In 2008 the Rzeszów branch of the General Directorate of State Roads and Motorways started modernization of a state road in the Podkarpacie region - the largest in its history. The project valued at almost PLN 600 mln was divided into four parts and consisted in reconstruction of 55 km of state road No 4 between Machowa and Łańcut. State road No 4 is currently the busiest road in the Podkarpacie region. Road No 4 connects the west and east borders of Poland and has international meaning as a part of both domestic and trans-european communication network TEN-T. In the future it will function as an alternative for the currently realized A4 motorway.We were entrusted with modernization of the technologically most difficult and the longest -over 23 km - section of the state road No 4 between Pilzno and Ropczyce. This section starts right at the end of the Pilzno by-pass realized by us in 2005 and ends at the outskirts of Ropczyce, where it joins the by-pass.The investment realized by our company was a considerable challenge due to the length of the modernized section, vast scope of construction works and the necessity to provide continuous traffic in both directions on the busiest of the roads in the Podkarpacie region. Completed construction works were valued at more than PLN 302 m gross. It was the largest ever project our company realized on the territory of Podkarpacie. In summer 2009, at the peak point of investment realization, construction works were realized by almost 430 people and 160 machines and transport trucks. The modernized, over 9-km section between Ropczyce and Nagawczyna was handed over to the investor in April 2010, whereas the works on the 14-km section of the same state road between Nagawczyna and Pilzno were completed in April 2011.
Realization of the investment resulted in the increase of capacity of both the road as well as the adjoining engineering facilities for more than 20 ooo drivers who cover this route everyday. The contract included realization of a series of solutions and conveniences improving considerably the safety of all traffic users, i.e. reconstruction of crossings, erection of more than 160 traffic routing hatched areas, pedestrian lines and islands. We reconstructed 13 pedestrian crossings and - on aluminium supporting structures -installed active road signs with pulsators and lightening. The investment contributed to the decrease in the number of road accidents thanks to the fact that additional overtaking and turning lanes were sectioned, grade line and lane curves were corrected and almost 10 km of protective barriers were installed. We also installed 1150 new road signs and more than 10 000 point reflecting elements. We erected two lighting panels with variable content which provide the drivers with current information about weather conditions on the road.

Segment rynku: Roads, Bridges
Within the realization period of 34 months we reconstructed the following objects: 23 km section of road, 6 bridge facilities, 34 culverts, 34 crossings with voivodeship and local roads and 20 bus bays. We erected 5 km of acoustic screen panels, 2 roundabouts, 16 km of sidewalks and 5,5 km of service roads. Within the investment we also reconstructed gas, sewerage systems, water supply, power supply and communication networks. We installed 5 storm rain water purification separators and planted 5,7 000 trees and bushes. All the works were realized on a functioning state road.The contract included reconstruction of two crossings in Dębica: with Wielkopolska, Krakowska and Gumniska streets, on which two roundabouts were realized. The roundabouts are 50 m and 40 m in diameter and they will facilitate access to the state road; they are also equipped with special lanes for oversize vehicles.Reconstruction of viaduct and 5 other bridge facilities was a signiicant part of this investment. Construction of a new 187-meter carriagewy over the Wisłoka river in the town of Łabuzie near Pilzno was the most difficult technological part of engineering works. Two parallel bridges were realized with the use of cantilevering method, which was implemented for the first time ever in the Podkarpacie region. This method consists in realizing the so called starting segment first and then building the remaining sections of the bridge on both sides simultaneously.In the town of Latoszyn on the Ostra river we realized another two parallel bridge facilities, each of them 49 meter in length. We also reconstructed a 30-meter bridge over the Zawadka river in the town of Zawada and a 43-meter viaduct over Gajowa street.While realizing reconstruction works over the Gajowa street, we executed a temporary facility which enabled to preserve continuous traffic operation on the state road.
