TERMINAL 1 AND 2, LESTER B. PEARSON INTERNATIONAL AIRPORT

Originally built in 1964, by the early 2000s, Terminal 1 had outlived its usefulness. Its circular design, with a parking lot on top, was once a marvel of engineering but left no room for expansion.

Due to the project’s immense size and complexity, the project’s priority was focused on safety. Safety perimeter fence, demolition sequence, utilities and services decommissioning, water supply, and fire watch were the main safety considerations items stipulated in the demolition Plan.

The Old Terminal 1 was a combination of two main structures, the outer ring structure and the centre 9 level parking structure. While demolition took place, the airport remained in use and existing airport features were protected. PDI operated under height restrictions and obtained additional permits for equipment and high reach machines to ensure we would not interfere with aircraft sightlines.

PROJECT HIGHLIGHTS

This project was valued at $21 Million

Scrap metals totalling 24,000 tonnes were processed and stockpiled on-site into their own categories; weighed and shipped offsite to be recycled at appropriate steel brokers and vendors locations. 253,000 tonnes of concrete from columns, beams, slabs and walls were weighed, shipped and processed within the site. Asphalt weighing 10,000 tonnes removed from the parking garage and roads within Old Terminal 1 was shipped to be recycled at local asphalt plants. 1,500 tonnes of brick rubble, 110 tonnes of drywall, and 2,900 tonnes of waste were recycled at various recycling and disposal services

100% of scrap metals, concrete and brick rubble, 99% of asphalt and drywall, and 95% of the other waste was recycled. Overall, an average of 98% of the demolition materials was recycled which met and exceeded GTAA’s ISO 14001 mandate and target of 80% recycling

This project commenced in November 2003 and was completed by November 2004

PDI IN ACTION

“The Terminal 1 job was the project that was a turning point for us in being able to bid larger projects without being afraid of actually doing them.”
