plate girders and at bearings
where b is width
of the member
b) at other places 0.015 b to a
maximum of 4 mm
where b is width of
the member
8. Deviation from squareness of L/1000, where
flange to web of columns and
L is nominal length

above
12. Ends of members abutting at joints 1/600 of depth of
through cleats or end plates,
member subject to
permissible deviation from
a maximum of
squareness of ends

If the sub-structure and the superstructure are built under separate contracts, the Employer
will provide the substructure, constructed to correct lines, dimensions and elevations
properly finished and will establish the lines and the elevation required for setting steel.
