Lakhta Center, St Petersburg, Russia

The Lakhta Center is a large mixed-use non-residential development featuring the first supertall skyscraper in St. Petersburg. The 87 floor, 462 metre superstructure consists of a cylindrical reinforced concrete core. Due to exceptional reinforcement volumes, Ancon reinforcing bar couplers and headed anchors were used extensively in the construction of the foundation raft to avoid unnecessary overlapping of bars and minimise congestion. Nearly 80,000 CXL32 couplers were used for the splicing of 32mm horizontal reinforcing bars, and over 45,000 CXL32HA and 6,000 MBT ETHA32 headed anchors were used at the extremities of the reinforcement at the edges of the raft.
