Canada faces an acute civil infrastructure dilemma. Construction activities consume 50% of materials extracted from the earth’s crust and generate nearly half of the total solid waste, while the built environment accounts for about 40% of greenhouse gas (GHG) emissions. In chorus, civil infrastructure continues to deteriorate prematurely. Deferred maintenance has created a colossal backlog of aging structures, inflicting a veritable drain of national wealth and an infrastructure deficit evaluated at $125 Billion. Such a situation looms to stifle economic prosperity; stark reminders of the perilous condition of our civil infrastructure (e.g. collapse of Montreal’s Concorde Viaduct) continue to emerge.

加拿大面临着严重的民用基础设施困境。建筑活动消耗了从地壳中提取的50%的材料，产生了近一半的固体废物，而建筑环境约占温室气体（GHG）排放量的40%。与此同时，民用基础设施继续过早恶化。延期维修造成了大量积压的老化结构，造成了名副其实的国家财富流失和基础设施赤字估计为1250亿美元。这种情况隐约可见，扼杀了经济繁荣;我们的民用基础设施的危险状况（例如蒙特利尔的协和高架桥倒塌）的鲜明提醒继续出现。
