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 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.
