The increase of air traffic and of passengers connecting in Montreal prompted ADM to build a new centre dedicated to connecting passengers in transit. It is a building of some 5,000 m², with areas for customs clearance and passenger redirection. This new centre enables passengers in transit between flights to bypass the large customs hall and to be redirected simply and easily to their boarding lounge for their next flight. This project also helps to reduce congestion in the large customs hall.

Some very complex technical challenges had to be met for the structure, including a structure with a span of more than 17 metres to free up the circulation path for the refuelling vehicles that travel under the transit centre and the design of a huge pyramid-shaped skylight measuring 30.3 m by 17.5 m on the roof of the new space. During construction, a carefully orchestrated phasing enabled operations to be maintained, while continuing the activities of a temporary transit centre.

For this major project at the airport, NCK provided all structural engineering consulting services from design to construction supervision.
