Stroygazmontazh was initially founded in 2008 by Russian businessman and oligarch Arkady Rotenberg after he purchased five companies under the control of Russian oil and gas giant Gazprom.[1] Rotenberg is a close friend of Russian President Vladimir Putin, which has led to the S.G.M. Group and other firms under Rotenberg's control accepting a number of Russian government contracts.[7]


Crimean BridgeEdit

In 2016 and 2017 it was reported that Stroygazmontazh, with evident ties to Russian President Vladimir Putin, had accepted a contract in January 2015 to construct a bridge providing a railway link between Russia and Crimea by crossing the Kerch Strait, and that it had proceeded to begin construction.[1][8][9][10] The Russian government stipulated that Stroygazmontazh is to complete the railway link by August 1, 2019, and fully complete all works on the bridge by December 1, 2019.[1][11] Stroygazmontazh has never built a major bridge before.[12] Because of the risk of sanctions, no international insurance company has underwritten the potential $3 billion loss if the project goes wrong. So a small Crimean insurance company has underwritten it.[12]
