OF SUCH RECOMMENDATIONS.

1.SELECTING THE PROPER SITE
The selected site should be level, firm, and free from underlying debris. The bin can be installed satisfactorily
on slopes, but as the slope increases, additional labor and materials are required for the foundation. The
concrete foundation surface must be level. If some fill is required, it should be watered and tamped
thoroughly to prevent uneven settling from the weight of the bin. Naturally, the site must allow convenient
access for easy loading and unloading, plus provide additional space for future units. Also, consider the
positioning of handling equipment, availability of electricity, and the placement of fans, heaters, and gas
tanks.

2.SCRIBE THE DIAMETER
Having determined the center of the site, drive a small 2 x 4 in the ground to mark the center point of the
foundation. The top of the stake should be the same height as the finished foundation will be. Using one large
spike, nail a straight 2 x 4 (approximately 2 feet longer than the radius of the bin) to the top of the center stake.
This will enable it to swivel. Along the opposite end at a distance given in the foundation layout table, attach
a sharply pointed stake. The swiveling 2 x 4 will act as a compass, enabling you to scribe the correct diameter
of your foundation and later locate the anchor and stiffener bolt locations. (NOTE: Making the 2 x 4 two feet
longer than the radius will allow the 2 x 4 to also be used as a leveling device and for pulling concrete.)

3.PREPARE THE FOUNDATION
Having scribed the diameter of your foundation, proceed by digging the footing of the foundation. This
consists of a large circular trench dug just inside the foundation line. (Refer to foundation details for necessary
information.) Once the footing has been dug, you are ready to build the forms. It is important that your form
be rigid enough to hold its shape against the poured concrete. Also, the foundation must be flat. Sloped floors
cannot be used in drying bins. A carpenter’s level placed on top of your 2 x 4 will enable you to set the top
of the forms to match the top of the center stake. Check the form work with a transit to ensure a uniform
elevation for the entire foundation.

OCTAGONAL FOUNDATION FORM

There are two styles of foundation forms commonly used. The first is the circular form depicted in Figure
#2. The second style can be made of 2" x 8" boards set into a square with corners blocked off to form an
octagon. (See Figure #3 below.) This eight sided form will approximate a circle and can be constructed quite
easily.

When the foundation form is completed install reinforcement rods by either welding or wiring in place. Place
2" of compacted sand on the inside level of the foundation. The sand is then covered with a 4 mil plastic
moisture barrier. 6" x 6" wire mesh (2 mats), covering the entire area of the foundation, completes your
preparation of the bin’s foundation. You are now ready to begin pouring concrete.

NOTE: ALL CONCRETE IS TO HAVE A MINIMUM COMPRESSIVE STRENGTH OF 3,000 PSI
@ 28 DAYS.

NOTES:

•Foundation site should be well drained and free of vegetation or debris.

•Foundation design is based on a minimum soil bearing capacity of 3,000 lb/ft2. If soil bearing capacity
is in doubt, contact a local soil testing engineer.

•Concrete shall have a minimum compressive strength of 3,000 PSI at 28 days.

•Requirements for reinforcement do not include overlap.

•Lap all circumferential bars 35 bar diameters and stagger all laps in plan 3'-0".

•All material used for back fill inside the ring wall should be a clean, well graded, crushed stone or sand­gravel mixture. Back fill should be placed in 6" lifts and well compacted.

ANCHOR BOLT LAYOUT

Refer to following diagram for proper bolt layout.

Having poured and leveled the concrete, use the center stake and straight 2" x 4" again to find bolt circle radius
for the outside stiffener bolts. Select a starting point and stretch a pre-measured chord along the imaginary
circle formed by the bolt circle radius. Consider the placement of these bolts so as not to interfere with the
positions of bin doors and transitions.

Work both directions from first anchor bolt location, this will help eliminate possible error in laying out
anchor bolts. On larger bins sight across starting anchor bolt and center pin and place anchor bolt on opposite
side of anchor bolt radius. From this point you can work both directions from both anchor bolts.
