3. PRE-ASSEMBLY
3.1. SITE SELECTION
3. Pre-Assembly
Before continuing, ensure you have completely read and understood this manual’s
Safety chapter, in addition to the safety information in the section(s) below.
3.1. Site Selection
The selection of the site is very important. The following must be adhered to when
choosing a bin site:
• Choose a firm, level, well-drained site, so that snow/water cannot collect near the
grain bin.
• The soil on the site needs a bearing capacity adequate for the bin foundation design.
Refer to a qualified soil engineer for analysis of soil bearing capacity. Always consult
with an engineer who is familiar with local soil conditions.
• Bins should be clear from power lines or electrical transmission equipment. Contact
your local power company to obtain recommended equipment clearance information.
• Ensure that there is sufficient power available to operate any aeration or unload
equipment that is to be installed.
• Orientation: Consider loading equipment direction and unloading equipment direction when choosing a site.
• Hopper bins must not be located next to high buildings that may cause snow to buildup unevenly on the bin roof or cause uneven wind pressure. Both can result in bin
damage.
3.2. Site Conditions
Access routes to the site and within the site should be given on a site plan showing
dimensions and level of access routes, level of the prepared working area for site traffic
and plant, and areas available for storage.
Construction of the bin shall not start until the following site conditions have planned for
and evaluated for safety:
• provision and maintenance of hard standing surfaces for cranes and access equipment;
• access routes to and within the site should be included on the site plan;
• soil conditions affecting the safe operation of the structure;
• possible settlement of erection supports for the structure;
• details of underground services, overhead cables or site obstructions;
• limitations on dimensions or weights of components that can be delivered onto the
site;
• special environmental and climatic conditions on and around the site;
• particulars of adjacent structures affecting or affected by the works.
ENM-18908 R2
15
3. PRE-ASSEMBLY
3.3. SITE PLAN VERIFICATION
AGI - 27’ HOPPER BOTTOM
3.3. Site Plan Verification
Before beginning to assemble the grain bin, a site plan must be completed. The
complexity of the site plan will depend on the size of the installation (a single bin vs
multiple) and should include the following details, where applicable:
• hopper bin location(s) clearly and accurately identified;
• hopper bin features such as ladder locations are also clearly marked, as well as the
location of roof features (e.g. indicate where inspection panels, vent panels, and roof
ladders will be located);
• any hazards (such as low electrical lines) must be identified clearly.
3.4. Foundation
Before assembling the bin, the foundation must be completed.
When constructing a foundation for the grain bin, local code and jurisdiction requirements that apply to the grain bin installation must be adhered to, as well as the design
and construction requirements listed in this manual.
Foundations must be designed for the highest loads that they are expected to support,
given the local soil conditions. Foundation guidelines are provided for a set of minimum
soil conditions that may not be applicable to all local conditions.
The bin foundation must be built on a site with good drainage, prepared by removing top
soil and organic material and replacing this with granular fill (gravel).
The AGI 27’ Hopper Bottom models are designed to be used with a suitable concrete
pad or concrete piles.
3.4.1. Concrete Specifications
The concrete must have a minimum compressive strength of f'c = 3000 psi (20 MPa) at
28 days. Construction errors or imperfections that cause high or low spots may require
level removal of concrete or shimming under support legs.
A layer of compacted gravel and supporting soil with a minimum bearing capacity of
3500 lb/ft2 (168 kPa) must first be prepared, on top of which the concrete pad must be
poured or through which the concrete piles must be poured.
3.4.2. Foundation Tolerances
The foundation must provide uniform and level support for the grain bin. Before assembling a grain bin, ensure that the bin foundation meets specifications for levelness and
correct dimensions. Construction errors or imperfections that cause high or low spots
must be remedied.
The foundation must remain level before and after loading. Any outof-level condition on the foundation will cause deformation or failure
of the bin sidewalls and hopper components.
Hopper bottom support legs must be laid out on a common circle, bolted in place on the
common radius within ±10 mm (3/8”). Adjacent support legs must be equally spaced
within ±10 mm (3/8”) measured by a chord between column centers.
A concrete pad used to support a hopper bottom bin must be flat, smooth, and level
within ±5 mm (3/16”) as measured across opposite sides of the pad.
16
ENM-18908 R2
AGI - 27’ HOPPER BOTTOM
3. PRE-ASSEMBLY
3.5. CHECK SHIPMENT
Concrete piles must be collectively level within ±5 mm (3/16”) as measured across pile
pairs that are furthest apart.
Note:
For both concrete pads and piles, differences in level between adjacent support legs can
be addressed with metal shims if it is still ensured that the overall tolerance is not
exceeded.
3.4.3. Anchor Bolts
Support leg anchor bolts must conform to ASTM F1554 (minimum), Grade AB36 Galvanized, and must also be sized appropriately (diameter, overall length, embedment depth,
thread length) by a qualified professional engineer.
Anchor bolts are not supplied by AGI.
For the 27’ Hopper Bottom model, each support leg baseplate requires at least 2
anchor bolts of 5/8” diameter minimum (placed in diagonal holes).
For the 27’ Hopper Bottom Seismic Zone 2B model, each support leg base plate
requires 4 anchor bolts of 5/8” diameter minimum.
3.5. Check Shipment
Unload the parts at the assembly site and inspect them thoroughly while comparing the
packing slip to the shipment. Ensure that all items have arrived and that none are
damaged.
It is important to report missing or damaged parts immediately to ensure that proper
credit is received from either the manufacturer or from your distributor/dealer, and to
ensure that any missing parts can be shipped quickly to avoid delaying the assembly
process.
Note:
Do not attempt to assemble or install a damaged component.
3.6. Storage of Materials
Many hopper bottom parts are made of galvanized steel (coated with zinc to provide
protection from rust).
If moisture (rain or condensation) gets in between the materials, or is allowed to
accumulate on materials, and is not dried immediately, “white rust” can form, reducing or
removing the zinc layer that protects the steel from destructive and structurally
dangerous “red rust.”
3.6.1. Long-Term Storage of Materials (Indoor Only)
• Store all materials in a dry indoor environment where there is no risk of leaks or
flooding (wall-sheet bundles, roof sheets, bin-boxes, ladder boxes, and hardware
boxes).
• If there is any risk of leaks or flooding at an indoor storage location, cover with a wellsecured water-proof tarp that is wrapped to provide venting (allows a protected
exchange of air to prevent build-up of moisture under the tarp).
• Raise all materials 6” to 8” (152 mm to 203 mm) above floor level.
• Elevate hopper sections 12” (305 mm) at the narrow end of the sheets during longterm storage.
ENM-18908 R2
17
3. PRE-ASSEMBLY
3.7. LIST OF TOOLS AND EQUIPMENT
AGI - 27’ HOPPER BOTTOM
3.6.2. Temporary Storage of Materials (Indoor and Outdoor)
• Temporary indoor storage does not require special concern, apart from storing in a
dry environment where there is no appreciable risk of leaks or floods.
• Temporary outdoor storage (i.e. on site, or associated with transport) requires all
parts to be covered with a waterproof tarp that is wrapped to provide venting (allows
a protected exchange of air to prevent build-up of moisture under the tarp). Raise all
materials at least 6” to 8” (152 mm to 203 mm) above ground or floor level.
3.6.3. If Parts Become Wet
To prevent white rust, follow the instructions below.
• Open bundles as soon as possible.
• Separate and stand materials upright, wipe dry, and let stand for a minimum of 24
hours to ensure dryness.
Brace materials properly to avoid damage or injury from material
falling when in storage.
• Wipe down wall sheets and apply petroleum jelly or food-grade oil with a clean, lintfree cloth.
Do NOT use oil or petroleum jelly on roof or ladder materials.
• If left uncared for, white rust can turn into red rust, which can be a structural concern.
Immediately replace any part with red rust on it.
Red rust has the potential to become a structural concern. Failure to
immediately replace any part with red rust may result in the collapse
of structure. Failure to protect against the effects of moisture will void
your warranty.
3.7. List of Tools and Equipment
Use correct, quality tools and equipment.
3.7.1. Tools Required
• electric or pneumatic (air) impact tools
• power drill and drill bits
• metal cutting saw
• measuring tape (100’) (30 m)
• sockets (multiple 1/2”, 9/16”, and 3/4” sockets recommended)
• large-pocket pouches for nuts and bolts
• 8” metal punches (for aligning bolt holes)
• step and extension ladders, construction grade
• 6-point wrenches (imperial, box end)
• scaffolding
• adequate powered lights as required

3. PRE-ASSEMBLY
3.8. BEFORE YOU BEGIN
3.7.2. Minimum Safety Equipment Required
First-Aid Kit
• Have a properly-stocked first-aid kit available for use should the need
arise, and know how to use it.
Other
• cable, chain, or rope to tie-off bin or jacks in case of wind
• electrical connections which are protected with ground fault circuit interrupters
(GFCI’s)
3.8. Before You Begin
• Before beginning assembly, familiarize yourself with all the sub-assemblies, components, and hardware that make up the equipment.
• Have all parts and components on hand, and arrange them for easy access.
• Separate the hardware (bolts, nuts, etc.) and lay them out into groups for easier
identification during assembly.
Note:
When options or more than one configuration is available for the equipment and the
assembly information varies, additional instructions will be included.
3.9. Bolts and Bolt Tightening
All the bolts that are required to assemble the bin are supplied.
Bolts and nuts used in AGI bins are specialty hardware that are an inherent part of the
overall bin design, and cannot be reliably replaced with different hardware, including
those that might by specification appear to be of equivalent design or strength. If
additional bolts or nuts are required for any reason (e.g. replacement/repair or insufficient supply during construction), contact your AGI dealer.
When tightening bolts, tighten the nut on the bolt until a “snug -tightened condition” has
been achieved, as defined in Specification for Structural Joints Using ASTM A325 or
A490 Bolts (Research Council on Structural Connections: June 30, 2004), which states:
“The snug-tightened condition is the tightness that is attained with a few impacts of an
impact wrench or the full effort of an ironworker using an ordinary spud wrench to bring
the connected plies into firm contact.”
All bolted connections in the bin must be tightened to a snug-tightened condition, and
any mention in this manual of tightening bolts indicates tightening to a snug-tightened
condition.
All assembly crew members must be made aware of this requirement, and must know
how to achieve a snug-tightened condition using common bin-building tools.

4.3. ASSEMBLY OVERVIEW OF HOPPER BOTTOM
AGI - 27’ HOPPER BOTTOM
4.3. Assembly Overview of Hopper Bottom
AGI recommends the following assembly method:
1.
Inspect the foundation that has been constructed for the hopper bottom, and ensure
that it meets or exceeds the specifications in Section 3.4. Foundation on page 16 as
well as the design specifications for the site-specific installation.
2.
Determine the placements for the support leg anchor bolts using the measurements
provided in “Placement of Support Legs” on page 24.
a. Use accurate measuring equipment (e.g. a transit and surveyors rod) to identify
high and low areas before placing the support columns on the anchor bolts.
b. Always attempt to determine level based on the highest support leg position that
has been established.
c. Place steel shims (not provided) between the concrete and support leg baseplate
to compensate for low areas.
d. When level, fasten each support leg baseplate loosely in position with suitable
anchor bolts (see “Anchor Bolts” on page 17 for anchor bolt specifications).
3.
Assemble the horizontal braces and cross-braces between support legs (see
“Assemble Support Legs and Bracing” on page 26). Bolt braces in place loosely; do
not tighten until step 9.
a. If desired, install optional A-frame brace(s) in accordance with Section 4.6.1. on
page 28.
4.
Assemble the ring beam (see “Assemble Ring Beam” on page 32).
5.
