The DSO Stroitel was established in 1936 as the sports club exclusively for construction workers of heavy industry of the "Center" - i.e. industrial heartland of the USSR. Later, it absorbed several other trade union sports clubs of construction workers. The club was dissolved in 1957 during the reorganization of Soviet sports movement.
