STG Built 20% of Frunzensky Bridge within a Year
29 November 2016
Project news
The construction of the Frunzensky Bridge commenced in Samara a year ago. The project’s general contractor, JSC Stroytransgaz, working 24/7, has maintained appropriate work rate and accomplished 20% of the project, as scheduled. It is planned that in 2017 the crossing is to be completed by 80%, and in 2018 the builders will have only 20% of the scope of works left to perform.
Vladislav Pototsky, the Director of the Infrastructure Construction at JSC Stroytransgaz, emphasized: “In 2016, we have worked in close cooperation with the client and the partners, i.e. subcontractors and Samara local suppliers. Despite the abnormally high flood, the first year has been quite successful for the project. Most of the work is to be done in 2017; the scheduled project financing gives reason to believe 80% of the bridge will be completed. We will have to finalize construction of the remaining river piers and complete launching of superstructure on the bridge across the Samara River. After that, the Frunzensky Bridge will take visible shape, so one could imagine its final appearance”.
The Governor of Samara Region Nikolay Merkushin stressed the facility importance more than once: “The Frunzensky Bridge will definitely attract the global traffic flow for decades ahead. We must to do everything to make the region a center of the intersection of the continent’s two key trunks connecting Europe and Western China”.
According to Ivan Pivkin, the Minister of Transport and Motorways of the Samara Region, the construction works on the bridge crossing are at a fast pace: “The contractor strives for getting out of the water throughout the winter to ensure construction and assembly works continue”.
Construction progress
By now, the 80-meter long reinforced concrete bridge across the boggy lake Bannoye, one of the basic elements of the Frunzensky bridge crossing, is almost completed. It firmly rests on the seven piers holding its superstructure. All four land piers for the main 667-meter long bridge connecting banks of the Samara River are finished; construction of the four river piers is underway.
On the river’s left bank, the builders construct the base line of the motor road using the sand dredging technology, which considerably reduces time for erection of the earthwork embankment of the future road. At some sections the embankment height exceeds 12 meters. These works require huge amount of sand - 430,000 cubic meters have been already laid now, and this is only 43% of the overall scheduled amount (1 mln cubic meters). The sand extracted from the bottom of the Volga River by the Samara River Port Company is delivered to the construction site on barges and, mixed with water, is put into the embankment mass via dredging pipe (the hydraulic fill technology).
Two traffic interchanges are being constructed at the same time: preparatory works and anti-deformation activities are held on the eight interchange ramps connecting to the Shosseynaya Street; the same work pace is kept at the Frunze Street interchange, where bored piles of the C-9 ramp sustaining walls are being currently arranged.
Extensive piling works have been performed over the past year. The builders have already made 379 bored piles and inserted 76 reinforced concrete driven prismatic ones. By the end of the project, foundations of all engineering structures of the Frunzensky bridge crossing will rest upon 2,081 piles. As a reminder, these structures include bridges across the Samara River and the Bannoye Lake, two traffic interchanges, six sustaining walls made of cast reinforced concrete, and the 70-meter long flyover to be located at the ramp over the primary traverse road.
Almost one third of the overall amount of concrete has been already laid down (about 14,000 out of 46,000 cubic meters), and one third of metal structures has been assembled (3,000 out of scheduled 9,500 tons).
