Montréal Data Center

Clients : Urbacon / Fonds de solidarité FTQ

ELEMA designed this cutting edge data centre which is located in the Ville-Marie bourough in downtown Montreal in the block bound by Montfort, St-Jacques and de l’Inspecteur streets.  This project included the construction of a new 10-storey data hall structure that was directly adjacent to an existing four-storey building with a floor area of 1,780 m² (19,140 ft²) that was converted into office space.  A new two storey electrical power station was added over the existing building. 

The new tower includes a 5.4 m (18 ft) cantilever at its north extent to prevent the building’s foundations from interfering with the Ville Marie Expressway tunnel located below the cantilever. 

The new $70M complex provides a total floor area of 24,775 m² (266,671 ft²).

TECHNICAL CHALLENGES :

  • Heavy floor design loads of up to 12 to 17 kPa (250 to 350 lbs/ft2).
  • Construction of the building cantilevering over the Ville Marie Expressway access tunnel.
  • Construction of an electrical power station 15 m (48 ft) above an existing building.
  • Seismic upgrading of the existing building.
  • High 5 m (16,4 ft) storey heights with a 10 m (32.8 ft) high upper storey.
  • 9.2 m x 9.2 m (30 x 30 ft) spans.
  • Floor consisting of concrete flat slabs using 300 mm (12 in.) drop panels.
     

NOTABLE SOLUTIONS AND INNOVATIONS :

  • North end of the building is cantilevered 5.4 m (18 ft) across the Ville-Marie tunnel, allowing the installation of 8 additional server bays. A bracing wall is supported on the cantilevered transfer at the SS1 level.
  • Design of steel seismic connectors linking the new structure to the existing building, the floor elevations of which did not match.
  • Construction of a 14.6 m (48 ft) clear height power plant above the existing building to allow delivery of the lower spaces of the building before completion of the upper floors.
