As architects, engineers, and builders push toward using sustainable, ‘green,’ and cost-effective building materials, National Building Code of Canada’s (NBC’s) tight framework with regard to combustible construction is coming into the spotlight. Combustible and non-combustible construction, and combustible elements in buildings required to be of non-combustible construction, are terms with which most industry professionals are all too familiar. Materials permitted for use in construction depend on the occupancy, height, and area of the proposed structure.

Most construction site fires can be prevented. However, for those that do occur, the impact can be significantly lessened with knowledge, planning, and diligence. Understanding and addressing hazards and risks for each construction site requires education and training, as well as preparation and perseverance.

A comprehensive moisture management plan for any construction detail must include moisture-resistant materials (e.g. dampproofing, water-resistant barriers [WRBs], and waterproofing) and a slope-to-drain—a designed elevation change to direct liquid water to a desired low point away from, off of, and out of the construction detail. It also involves an unobstructed pathway/void for liquid water to exit the construction detail.
