034701 R28 13

4.3. Selecting a Bin Site Location

Considerations when selecting a bin site:

• Convenience in loading and unloading, and accessibility to existing and planned facilities

• Adequate drainage to prevent water accumulation around the bin

• Soil stability

Note

Standard foundation drawings and specs are furnished by AGI showing soil bearing pressures

required. It is the obligation of the purchaser to obtain a soil bearing test and ascertain that the

foundation has sufficient strength for a capacity filled bin. Unless the finished foundation is level and

true, and the site properly graded for water drainage, failure of the foundation could result. This is

not covered by the AGI warranty.

• Access to utilities

• Environmental conditions such as high wind and snow load

• Neighboring structures

Important

Consult with local authorities for site-specific requirements.

4.4. Pre-Plan Assembly

Before assembling:

1. Read and understand this manual.

2. Predetermine the locations for anchor bolts, sign sheet, ladders, platforms, manway, roof steps, roof vents,

and other auxiliary equipment.

3. Develop an assembly plan, with consideration given to the layout of accessories and auxiliary equipment.

Plan your construction in accordance with your assembly and layout plan.

Important

Installation of accessories or equipment on grain systems equipment/structures that overstresses the

bin in any manner will void the warranties.

In cases where additional loading is involved, if you do not already have specific recommendations from

AGI, contact AGI engineering department before installation begins.

4.5. Preparing a Foundation

Foundation details in this manual are of general nature and are intended only as a guide. It is the owner’s

responsibility to provide an appropriate site and foundation design for the adequate support of the grain bin.

AGI assumes no responsibility arising from these suggestions.

1. Prepare the bin site. Ensure that it is level, compact, well drained, and free of vegetation and/or debris.

12′ – 21′ (3.66 M – 6.40 M) HOPPER BINS – FARM HOPPER BIN 4. BEFORE YOU BEGIN

14 034701 R28

Note

Any fill used in leveling the site must be well compacted to prevent uneven settling from weight of

the foundation, bin and contents. After the site is completely level, use 1″ – 2″ (26 mm – 50 mm) of

fill sand to act as a cushion under the concrete slab. Ensure the soil is compacted in accordance with

your soil engineer’s specifications.

Remember

If your soil is not right, your foundation could tip and crack.

2. Drive a small pipe in the pad center. The top of the pipe should be the foundation height.

3. Use the pipe for a center pivot. Attach a chain with a sharp stake attached to the outer end. Scribe on the

ground the foundation diameter. (A board may be used instead of a chain).

4. Set up formwork and add reinforcement, as required. Pour the concrete.

Important

Make certain that the work is being done in exact accordance with your soil engineer’s

specifications. If your foundation is not right, your bin could fail.

5. After pouring the concrete, and while it is still soft, locate your anchor bolts.

a. Use the center pipe and chain again to mark the correct diameter to set the anchor bolts.

b. Use a measured chain (or chord) to get the correct spacing between holes. See Anchor Bolt section.

Note

The anchor bolts should follow a scribed circle with the correct chord dimensions between the

anchor bolts. This will help ensure that the hopper bin legs/columns rest firmly on the foundation

with absolutely no overhang.

Figure 3. Laying out the Foundation

ST-102413

Important

Anchor bolts should be to specifications and be set when pouring the foundation. Improper

anchoring will give you a weak structure.

6. Inspect the foundation for any defects. Allow concrete to cure for seven (7) days before beginning the tank

assembly and 28 days before filling the bin.

7. Backfill around the foundation, as necessary.

The foundation drawings on the following pages are intended as a guide only and are not to be interpreted as

“firm” instruction. If at a later date, the bin is increased in height, the foundation may not be adequate.

Note

• The foundation site should be well drained and free of vegetation and/or debris.

• Foundation(s) should be on undisturbed soil or engineered compacted backfill.

• A soil and foundation (geotechnical) investigation should be conducted for each site to confirm the

soil bearing capacity.

• Foundation design is based on the specified allowable soil bearing capacity.

• The concrete shall have a minimum compressive strength of 3000 psi (20.67 MPa) at 28 days.

• Concrete should be allowed to cure seven seven days before beginning the tank assembly and 28

days before filling the bin.

• Concrete should be kept level to ±1/8″ (3 mm) in 10′ (3000 mm) and 1/2″ (12 mm) across the

diameter. High spots or debris should be removed prior to setting the bin.

• Anchor bolts need to be properly located, based on the information provided, to keep the tank

round, and to ensure structural integrity of the bin while guaranteeing effective transfer of wall

forces down to the foundation.

1. Minimum recommended cast-in-place anchors for standard conditions shall be A307 9″ x 3″

(229 mm x 77 mm) hooked bolts of the required diameter:

– 3/4″ (20 mm) for commercial flat-bottom bins and commercial hopper tanks

– 1″ (26 mm) required for 60’ (18.29 m) and larger bins with a side draw

– 5/8″ (16 mm) for unstiffened grain bins

– 1/2″ (13 mm) for unstiffened hopper bins

2. The hook of the bolt must be placed below horizontal rebar for proper transfer of forces.

3. Alternatively, a hex-head bolt with flat washers or an epoxy adhesive anchor of equivalent

strength may be used. Check with epoxy anchor vendor or manufacturer for strength ratings and

for proper installation instructions.

• All reinforcing rod for concrete reinforcement shall conform to ASTM A615, Grade 60.

• Rebar should lap a distance equal to (rebar diameter x 24). Minimum allowable lap is 18” (450 mm)

- i.e: #6 Rebar has a diameter of 6/8″ (19 mm): 24 x .75″ = 18″, or an 18″ lap (24 x 19 mm = 450 mm,

or a 450 mm lap).

• Estimates for rebar do NOT include allowances for the lap.

• The stiffener and sidewall must be supported over tunnels.

• Concrete yardage figures do NOT include any allowances for aeration trenches or tunnels.

• Ring reinforcement must be continuous around the tunnels.

• To help minimize potential frost heave, the bottom of the footings should be at or below the frost

line. Alternatively, the footings could be supported on non-expansive fill materials (such as crushed

stone or gravel) which are not susceptible to frost heave, extending below the frost line; however,

some local building codes do require the footing to extend below the frost line.

• Foundation design is based on an allowable soil bearing capacity of 3000 psf (143.64 kPa) for

unstiffened grain bins and 3500 psf (167.6 kPa) for commercial stiffened bins.

• The foundation details in this manual are to be considered general in nature and are intended only

as a guide. This design is for standard external loading conditions: 90 mph (145 km/h) wind speeds

and seismic zone 0 earthquake loads. It is the owner’s responsibility to provide an appropriate site

and foundation design for the adequate support of the grain bin. AGI assumes no responsibility for

4.6. Critical Assembly Requirements

To ensure a successful, safe and reliable outcome you must comply with the following assembly techniques and

practices:

• Comply with all local code and jurisdictional requirements applicable to your hopper bin installation.

• Design and build foundations with the necessary strength for the loads they must support, and for local soil

conditions. AGI foundation guidelines are based on specific stated conditions and may not be applicable to

local conditions.

• Your foundation must provide uniform and level support to the structure being supported. Surface

imperfections causing gapping must be remedied. This may involve, but not be limited to shimming under

the legs of a hopper.

• Make sure that the proper hardware is utilized for all bolted connections. If a shortage occurs, do not

substitute. Take the necessary steps to obtain the proper hardware. Make sure nuts are tightened to the

required torque values as specified in the appropriate assembly manual.

• Before anchoring your structure to its foundation, make sure the structure is round. The maximum variation

from perfect roundness is 3/4" on the radius. Locate anchor bolts toward the outside of the anchor bolt

holes (away from the circle) to permit the incremental expansion that can occur with the initial filling.

• If extending an existing bin or tank, ensure that the foundation is adequate for the increased loads it must

support.

• Comply with all assembly instructions provided in the appropriate assembly manual to make sure your

whole hopper bin is constructed safely.

Important

The product warranty is void if:

– Wall sheets and/or uprights not specified for a given tier are used.

– Foundations are found to be inadequate or out-of-level.

– Anchor bolts (cast-in-place, drill-in, chemical type or other) are found to be inadequate.

– Off-center loading or unloading is used. (This does not apply to the use of approved side

unloading systems).

– Materials stored are not free-flowing or have a compacted bulk density greater than 50 lb/ft3

(800.9 kg/m3), 62 lb/bushel, maximum.

4.7. Product Storage

Rust on Galvanized Parts

1. White rust forms when moisture is allowed to collect on galvanized surfaces that have yet to develop the

durable zinc oxide layer. This zinc oxide layer naturally occurs as the surface interacts with carbon dioxide,

and is characterized over time by the dull grey appearance that weathered galvanized surfaces get.

2. Parts that are not well ventilated or well drained can collect water between surfaces and develop white rust.

3. White rust is not a structural concern if its development is stopped in the early stages. A light film or

powdery residue can occur after a period of heavy rainfall or a short time of improper storage. If white rust

has started to develop, separate parts and wipe off any moisture. Next, using a clean cloth, apply a thin

layer of petroleum jelly or food-grade oil to the entire part.

4. If moisture is left on parts, this white rust can become more aggressive and turn into red rust. Red rust can

cause degradation in the material and become a structural concern. Any parts that have red rust should be

replaced immediately.

Storage Guidelines

• Keep all bundles dry before assembly of the bin.

• Start assembly as soon as possible.

• Do not lay bundles on the bare ground. Raise all bundles 6" to 8" off the ground on wood blocks or timbers.

(See Detail A in Figure 10 on page 19).

• Store curved wall sheets ‘hump-up’. (See Detail A in Figure 10 on page 19.)

• All other bundles material should be placed so that they are well sloped to promote good drainage. (See

Detail B in Figure 10 on page 19).

• Roof sheets must be elevated at least 12" at the small end of the sheets. (See Detail B in Figure 10 on page

19).

• Temporary storage can be provided by erecting a simple framework supporting a waterproof tarp. (See

Detail C in Figure 10 on page 19).

• All bin boxes, ladder boxes and hardware boxes should be stored inside. These are not waterproof, and will

deteriorate in normal weather conditions, allowing moisture to contact the parts inside.

If Parts Become Wet

1. If goods become submerged or wet, the

bundles should be opened as soon as possible,

sheets or material separated and dried. Keep

separated until assembly. Brace goods

properly so as to avoid damage or injury from

material falling when in storage.

2. Any boxed goods that become wet should be dried and stored in a new box that is free of

moisture.

3. In addition to wiping down wallsheets, a food-grade oil can also be applied with a clean,

lint-free cloth. This will assist in preventing any further moisture from contacting the

galvanizing on the steel. Due to safety concerns with installation and use, Westeel does

not recommend the use of oil on other parts such as roof sheets and safety ladders.

4.8. Grain Bin Use

• Fill the bin through the center roof opening only.

• Do not overll the bin roof area! This may cause roof damage or failure.

• Do not off-center unload a grain bin. It is imperative to unload from the center of the bin first, until as much

grain as possible has been removed, and only then proceed to unload from the next closest unload gate to

the center. Continue utilizing the unload gates in succession from the center towards the outside. Gate

control mechanisms should be clearly marked and interconnected to prevent an external gate from being

opened first.

• The only exception to center unloading is when a properly designed and installed side draw system is

utilized. However, as bins tend to go out of round when employing side draws, the bin must be completely

emptied before refilling.

• When unloading a bin with a mobile auger through a properly designed auger chute, the entry end of the

auger should be pushed into the center of the bin before the auger is engaged. Slower rates of flow are

preferable and should not exceed the capacity of an 8” auger.

• Ensure that the inner door panels of grain bin doors are completely closed and latched before filling the

grain bin.

• Never enter a loaded grain bin for any reason. Grain can be a killer.
