Paris-Orly, a huge project

Re-building the runway at France’s second biggest airport is not an everyday occurrence… The renovation and upgrading of runway 3 at Paris-Orly airport, built soon after the WWII and extended in 1959, had become essential. Colas Île-de-France Normandie secured the contract for the project, as part of a consortium with Colas Projects, Spie batignolles valérian, JDC Airports and Cegelec.

Between July and December 2019, teams pulled off a technical, logistical and environmental feat. With an average of 33 million passengers per year and 627 flights per day, deadlines were tight. At the height of operations, 700 people were working on site, alongside more than 150 machines and heavy trucks. As part of a circular economy approach, the concrete removed from the former runway was recycled in situ and either re-used for the new runway or sent out for use on other sites in the Paris area.
