Abstract: Marseilles’ new high rise tower, La Marseillaise, is currently erected, surrounded by two concrete highways viaducts and nearby post-industrial harbors docksides. The tower is part of an urban piece composed of three other projects, architectural key players in the renewal of Marseilles waterfront skyline, within larger Euro-Mediterranean framework. The facades are composed of UHPC (Ductal®) prefabricated elements that participate in building’s envelope (air and watertight sealing), in thermal insulation, in solar control (sun-shades and lateral partition grids inclusion), in the building maintenance (cantilevered outgrowth of a peripheral gangway), in fire partitioning (high-rise towers regulation), as well as in sustainability (resistance to salt spray due to Mediterranean Sea proximity). The building site being extremely constraining, facades erection has been highly simplified by the condensation of technical functions into monolithic and repetitive precast elements. UHPC made this multi-technical nature of the envelope come true thanks to its various inherent properties: leak-tightness, fire stability, ductility, durability, high mechanical performances in flexion and compression.
