TOLERANCE FOR FINISHED FORMED CONCRETE SURFACES
*Class A-HV, in the
direction of waterflow .......................... +0 in.
........................ -1/8 in.
perpendicular to the
direction of waterflow ......................... 1/8 in.
Class
A
............................................. 1/8
in.
Class
B
............................................. 1/4
in.
Class
C
............................................. 1/4
in.
Class
D
............................................... 1
in.
*Includes any high-velocity flow surface.
(3)
Gradual variation
Surface finish tolerances as measured by placing a freestanding
(unleveled), 5 ft straightedge for plane surface or curved
template for curved surface anywhere on the surface and
allowing it to rest upon two high spots within 72 hr after concrete
placement. The gap at any point between the straightedge or
template and the surface shall not exceed:
*Class
A
(including Class A-HV) ...................... 1/8
in.
Class
B
............................................. 1/4
in.
Class
C
............................................. 1/2
in.
Class
D
............................................... 1
in.
*Includes any high-velocity flow surface.
TOLERANCES FOR CAST-IN-PLACE, VERTICALLY SLIPFORMED
BUILDING ELEMENTS
(1) Translation and rotation from a fixed point at the base of
the structure:
For heights 100 ft or less .............................. 2 in.
For heights greater than 100 ft,
1/600 times the height but not more than ................ 8 in.
(2)
Lateral alignment
Between adjacent elements ................................... 2 in.
(3)
Cross-sectional dimensions
Wall thickness ........................................... +3/4 in.
........................................... -3/8 in.
(4)
Relative alignment
Formed surface slope with respect to the
specified plane .................................. 3/4 in. in 10 ft
