Plumb deviation for a 50m steel chimney

[rubsy]

What is the acceptable out of plumb deviation for a 50 meter steel chimney. At the moment we are erecting 27 meter chimney is 5 inches out of plumb.

The CICIND code for steel chimneys specifies an out-of-vertical tolerance of 25mm or H/600, whichever is greater. For a 50m stack the out-of-vertical tolerance would be 83mm (H/600). By comparison, 5" in 27m is approximately H/200.

Refer to International Committee on Industrial Chimneys' webpage,

for more information.
