The Mariinsky Theatre in St. Petersburg is globally renowned as a symbol of Russian culture and artistic excellence. In an international architectural competition, Waagner-Biro Stahlbau AG was awarded the overall contract for the demanding new construction. The design by the renowned architectural firm Diamond Schmitt Architects (Canada) was selected due to its sensitive approach to the architectural heritage of St. Petersburg’s Old Town.

Commissioned by Waagner-Biro, NCA was entrusted with the implementation of numerous complex structural steelwork elements in the interior. Particularly noteworthy is the multi-story foyer with its impressive ceiling height, where several outstanding steel elements were realized.

The components realized by NCA include:
• a free-floating, cable-suspended oval staircase spanning several floors
• a 35 m long glass staircase that makes visitors appear to float between levels
• a VIP bridge for exclusive access to the gallery
• single and double-flight staircases
