Purpose of non-structural topping over PC planks
Purpose of non-structural topping over PC planks
(OP)
I have a proposed floor with 10" pre-cast floor planks topped with 2" non-str conc topping. The arch asked if we could get rid of the topping and she can use a wood flooring instead as a finish. My response was that the 2" is nominal and it varies a bit across the span of the plank and is basically there to provide a leveled floor. Was I right? I always thought of this topping as a tool to provide a level floor in a plank that has camber/deflection.

WHY DOES YOUR ARCHITECT CARE?

Without the topping there will be irregular joints and a curved (cambered) floor level. Also, the topping is used as a cap and means of connecting the plank system to supporting walls.
Without the topping, the connection between wall and plank is more difficult.

Jed...the architect believes that taking out this topping will save money. She is unwilling to re-think about the arched (actually semi-circular) doors on both entrances and some other rather lavish features but removing topping is supposed to make up for that.
