ABSTRACT
The construction of the Second Stage building of the State Academic Mariinsky Theatre (SAMT-2) has become a unique event in Saint Petersburg’s construction field. For the first time a 12 m deep triple layer underground storage of a large area was constructed in the historic centre of the city. The process was aggravated by compact soil area and densely builtup surrounding area, the immediate vicinity of the Kryukov Canal and the main theatre building, difficult geotechnical and hydrogeological conditions. Such kind of construction presupposed the application of special engineering and design methods, new structures and materials, management technologies and methods allowing a large number of construction companies and their employees work simultaneously.
