9.10.14.5.(12)

Intent 1:

To exempt heavy timber and steel columns from the requirements of Sentence 9.10.14.5.(1), which would otherwise impose certain minimum construction requirements relating to fire-resistance rating and type of construction, if certain conditions are met, on the basis that:

• the limiting distance is sufficient to limit the probability of severe fire exposure of the columns in the event of a fire outside the building, and
• the columns are outside the building and protected from exposure to a fire in the building by the exterior walls.
