tolerance without sign means plus or minus. Where only one signed
tolerance is specified, there is no limit in the other direction.
1.4.1
Conventional Concrete Surfaces
The definitions of the terms used in the following tables shall be as
defined in ACI 117.
TOLERANCES FOR CAST-IN-PLACE, VERTICALLY SLIPFORMED
BUILDING ELEMENTS
(1)
Vertical alignment
Translation and rotation from a fixed point at the base of
the structure:
For heights 30 m or less ................................... 50 mm.
For heights greater than 30 m,
1/600 times the height
but not more than ......................................... 200 mm.
(2)
Lateral alignment
Between adjacent elements .................................. 50 mm.
(3)
Cross-sectional dimensions
Wall thickness ........................................ plus 19 mm.
....................................... minus 10 mm.
(4)
Relative alignment
Formed surface slope with respect
to the plane shown in the drawings .............. 18 mm in 3000 mm.
TOLERANCES FOR CONCRETE STRUCTURES OTHER THAN
BUILDINGS
(1)
Vertical alignment
Visible surfaces ........................................... 30 mm.
Concealed surfaces ......................................... 65 mm.
Side walls for radial gates and
similar water-tight joints .................................. 5 mm.
(2)
Lateral alignment
Visible surfaces............................................ 30 mm.
Concealed surfaces.......................................... 65 mm.
(3)
Level alignment
