Completing the Place Ville Marie Complex at the time of its construction in 1969, 5 Place Ville Marie was then a 14-storey building closing the west side of the square. Four floors were added to the building in 1981, completing it as we know it today and bringing it to a height of about 68 m. Originally known as the IBM building, the architecture of the façades is a replica of the computer cards of the time, the location and opening of the building’s windows acting as a reproduction of the punch codes of a computer card. In addition to being a challenge for the structural engineer, the addition of the four new floors was completed without interrupting operations and without inconveniencing the occupants.
For this project, NCK provided complete structural engineering consulting services.
