Slab Cut Voids should be within the BUA outline for habitable floors and within the parking polyline for parking floors.
Slab Cut Voids drawn within a floor plan are considered to be at the floor level, not the ceiling level, for all floors except the lowest basement.
For the lowest basement, voids are considered at the ceiling level and are not deducted from the gross parking area.
All Slab Cut Voids in the basement floor plan should be aligned with those in the floor plan immediately above ground level. Example: If there is a stilt floor above the basement floors, a Slab Cut Void polyline should be aligned with the Slab Cut Void polylines in the basement floor plan.
Slab Cut Void area will be considered in the calculation of the total basement ventilation area.
