Drainage, lighting, and repair work on existing fencing, installation of a megadome (temporary) and a reservoir at Sept-Îles Airport

Hydro-Québec wishes to carry out work on land at the Sept-Îles airport. The new developments are required to meet operational needs and consist of:

- Constructing a drainage ditch

- Carrying out lighting work

- Installing a temporary 120-foot by 60-foot megadome

- Repairing an existing fence

- Installing a slab and a 2,359-liter oil tank

This work will require the use of conventional machinery (excavator, wheel loader, road roller, forklift).
