📋 Tender Overview
The Ministry of Construction of Russia has updated the set of rules SP 46.13330.2012 SNiP 3.06.0491 Bridges and Pipes SP 46 which regulates the performance and acceptance of work during the construction of new reconstruction and overhaul of existing permanent bridges and pipes under the embankments of railways metro lines and tram motor roads on the streets and roads of cities towns and rural settlements. Amendment No. 2 to JV 46 entered into force on September 3 2021.The development of the construction industry in Russia requires a wider use of effective and modern materials including polymer composites the use of which in bridge structures is especially important for the regions of the North and mountainous areas. Amendments to SP 46 are necessary for the centralized generalization and standardization of the requirements for polymer-composite bridges and culverts ensuring the operational reliability of structures as well as for mutual coordination with the current national standards said Deputy Minister of Construction and Housing and Communal Services of the Russian Federation Sergey Muzychenko.The main advantages of using composite materials in bridge construction in comparison with steel bridge structures are resistance to corrosion and corrosive environments seismic resistance low weight which allows to reduce the cost of transportation installation and construction of support elements and a decrease in operating costs with a service life of at least 100 years. When developing amendments to the set of rules the experience of construction and operation of polymer-composite bridges in Russia and abroad was taken into account.Amendment No. 2 to SP 46.13330.2012 SNiP 3.06.0491 Bridges and Pipes allows at the state level to implement a unified approach to the design of composite bridges creates conditions for passing the State examination of projects establishes uniform quality criteria in the field of composite bridge construction which will ensure reliability and will contribute to the dynamic improvement of domestic standards through the accumulation analysis and the possibility of comparing technical information on the facilities in operation. Development of the project Amendment No. 2 to SP 46.13330.2012 SNiP 3.06.0491 Bridges and Pipes was organized by FAU FCS and executed by JSC TsNIITS.
