goCapeBreton.com did an article on the amount of construction planned and occurring in the area. They call it "The Big Build", and are doing a series individual articles on some of the developments mentioned.
The Big Build — Billion-Dollar Construction in the CBRM
NSCC Marconi Downtown Campus Rendering
NSCC Downtown, CBRH Expansion, Glace Bay Hospital Renovation, New Waterford Community Hub, Northside Health Center, Sydney Fire Station are listed in the article, as well as a seventh section for "other projects" to be expanded upon in later articles. This would presumable be things like Horizon Acheivment Center; the library development with the associated hotel, apartment, parking garage, and office building project on the waterfront; the Jasper's development (apartments on George/Dorchester); and the train station development, as well as others I'm probably missing.
