Though a general contractor or construction manager has not yet been named, Soletanche-Bachy is beginning work on the diaphragm slurry wall for a planned 1,970-ft-tall tower in Moscow, designed by Foster and Partners with structural consultant Halvorson and Partners. The 3.7-million-sq-ft mixed-use tower, which if completed as planned would be Europe’s tallest, has three tapered wings radiating from a central core. The structural system consists of a spine braced by expressed sloping concrete columns. The columns both prop the structural concrete core against wind loads and carry gravity loads. Completion is scheduled for 2012.
