Built on René-Lévesque Boulevard, the Courtyard Mariott hotel is a 40-storey building, the first 12 of which consist of a hotel with a sports centre and swimming pool, meeting rooms and reception areas. The tower’s upper floors are dedicated to luxury apartments. The complex also includes 4 floors of underground parking with 243 spaces.
The main tower is 140 metres high and made of reinforced concrete. Due to its windy location, the main challenge was to create a structure that was rigid enough to limit movement and vibration due to the wind, in accordance with all requirements of current codes and standards. Half of the columns had to be relocated due to the presence of large conference rooms on the lower floors. These transfers involved the use of steel beams cast in concrete.
For this exceptional project in downtown Montreal, NCK provided all structural engineering services.
