Before continuing, ensure you have completely read and understood this manual’s
Safety section, in addition to the safety information in the section(s) below.
5.1. Assembly Safety
• Do not take chances with safety. The components can be large, heavy, and hard to handle.
Always use the proper tools, rated lifting equipment, and lifting points for the job.
• Carry out assembly in a large open area with a level surface.
• Always have two or more people assembling the sealform.
• Make sure you have sufficient lighting for the work area.
• Tighten all fasteners according to their specifications. Do not replace or substitute bolts,
nuts, or other hardware that is of lesser quality than the hardware supplied by the
manufacturer.
• Stay away from overhead power lines and other obstructions during assembly. Contact with
power lines can cause electrocution.
• Do not work in high winds.
5.2. Site Selection and Preparation
1. Choose a firm, level, well drained site. Consult your grain bin installation guide for general site
considerations.
Important
The concrete form foundation may transfer up to 2500 lb/ft

to the soil. For general soil bearing
values see
Table 1 on page 16
. These should be used for comparative purposes only. The intended
site should be checked for adequate bearing capacity.
