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.
