The 116-year-old Halifax Armoury may soon get major cosmetic and structural improvements, to revitalize and strengthen the building's west-facing wall.

The work is expected to cost $15 million, according to an advance procurement notice issued Thursday by Defence Construction Canada.

The project hinges on funding from the Department of National Defence.

If approved, the process to find and hire a contractor would begin in June 2016.

The construction would "include the deconstruction and reconstruction of the armoury's masonry west wall, including the removal and reinstatement of an interior mezzanine," the procurement document states.

The Halifax Armoury originally opened in 1899 and has aided in many Canadian wars. It is currently used by the military's Princess Louise Fusiliers, a reserve regiment.

The building — also referred to as the Halifax Drill Hall — received designation as a National Historic Site in 1989.
