Note: :
1.
Reduced foundation concrete volume and steel reinforcing may be possible when
site-specific geotechnical data is available. Standard foundation designs are
based on ANSI/TIA-222-G presumptive clay soil parameters which may be
conservative for many site locations. Larger foundations may be
required
for unusually weak site-specific soil conditions. Contact ROHN for
site-specific foundation designs when geotechnical data is available for a
site.
2.
Foundation details are provided for illustration purposes only and are not for
construction. Complete foundation details, anchor rod layout details and
foundation specifications are provided with the assembly drawings for each
tower.
3.
The purchaser must verify the suitability of a standard foundation design based
on actual site conditions including the strength of soil, sloping grade, frost
penetration and the potential for expansive or corrosive soil, etc. Foundation
design modifications may be required based on site-specific conditions.
4.
A site-specific investigation is required for Structure Class Ill towers per
ANSl/flA-222-G.
