02.
SUBSTRUCTURE
This element includes the enclosing horizontal and vertical elements required
to form a basement, together with the necessary mass excavation.
At level B it is subdivided into:
- Slab on Grade
-
including all underfill, foundation
drainage, trenches in slab, pits
and bases.
- Basement Walls
-
including required moisture
protection.
The section does not include any suspended structural slabs and supporting
interior walls and columns contained within basements, which are to be carried
in section 03.
In cases where slopping site conditions create variable basement levels, note
that only basement walls below grade are to be carried in this section. All
other walls above grade are to be included in section 04.
The items included in this section can perhaps best be described by the term
"bath tub", comprising essentially basement walls.
In cases where no basements are present, then only slab on grade is included
in this section.
