GBA led the creation of a world-class facility for Canada Post. This flagship project resulted in the redevelopment and master planning of one of the major federal employment nodes of Ottawa — a development program of over 2.5 million square feet. As a key member of the development team, GBA developed a business case which determined the funding and development model for this large-scale public-private project. The role included the complete master planning of Confederation Heights, where the headquarters is situated.
