3. BEFORE YOU BEGIN FARM SERIES EXTENSION TIER 15-48 WIDE-CORR GRAIN BIN 3. Before You Begin 3.1. Bin Design and Capacity Standard Westeel Grain Bins are designed for: 1. Non-corrosive free-flowing materials up to 55 lbs/ft 3 (880 kg/m 3 ) average compacted bulk density. 2. Maximum horizontal gusted wind speed of 94 mph (151 km/h) 3. Zero seismic activity Note Seismic resistance in grain bins varies with height and diameter. Many standard designs have significant seismic capabilities. Designs can be reviewed and/or modified to reflect local seismic requirements. 4. Roof loading capabilities vary with diameter, peak load and snow load. a. Peak Loads standard peak loads follow. Upgrades are available. Table 1. Peak Loads for Various Roofs Size Type of Roof Load (lbs) Load (kg) 15 to 24 non-structural 4000 lbs 1814 kg 27 to 48 non-structural 5000 lbs 2268 kg 51 & 54 non-structural 8000 lbs 3629 kg 48 to 108 structural 20,000 lbs 9072 kg b. Roof Snow Loads (RSL) at the above stated standard peak loads, standard RSLs vary with diameter and range from 16 psf (78 kg/m 2 ) to 49 psf (239 kg/m 2 ). Upgrades are available. Note The correlation between ground snow load (GSL) and roof snow load (RSL) for grain bin designs vary with jurisdictions. In the US GSL = 2 x RSL. In Europe GSL = 1.25 x RSL. In Canada the correlation between GSL and RSL varies and is site specific. 3.2. Foundation Design and Loads The foundations for the stiffened bin models are based on 4000 lbs. per sq. ft. (192 kpa) soil bearing capacity. All foundation designs use 3000 lbs. per sq. in. (21 MPa) ultimate compressive strength (after 28 days) for concrete and 43,500 lbs. per sq. in. (300 MPa) re-bar. The foundation designs included in this manual are suggestions only, and will vary according to local soil conditions. Westeel will not assume any liability for results arising from their use. Important Foundation should be uniform and level. Level should not vary by more than ¼" over a span of four feet under the bottom ring angle. Any variance from level must be shimmed under upright base assembly. If being utilized to support a full floor aeration system, this levelness requirement should extend across the complete floor area. 8 198864 R11

FARM SERIES EXTENSION TIER 15-48 WIDE-CORR GRAIN BIN 3. BEFORE YOU BEGIN 3.3. Site and Assembly Unless otherwise specifically provided in writing, Westeel does not take responsibility for any defects or damages to any property, or injury to any persons, arising from or related to any site or assembly considerations, including but not limited to: Bin location and bin siting Soil conditions and corresponding foundation requirements (note that the examples provided in manuals are for specifically stated soil conditions) Bin assembly (Westeel recommends the use of qualified bin installers; contact Westeel for information on installers in your area) Field modifications or equipment additions that affect the bin structure Interconnections with neighboring structures Compliance with all applicable safety standards, including but not limited to fall restraint systems (ladders or other systems). Local safety authorities should be contacted as standards vary between jurisdictions. 3.4. Methods of Installation The recommendations for assembling and installing Westeel grain bins must be closely followed to achieve the full strength of the bin and to achieve adequate weather sealing. The product warranty is void if: 1. Wall sheets and/or uprights not specified for a given tier are used. 2. Foundations are found to be inadequate or out-of-level. 3. Anchor bolts (cast-in-place, drill-in, chemical type or other) are found to be inadequate. 4. Off-center loading or unloading is used. (This does not apply to the use of approved side unloading systems.) 5. Materials stored are not free-flowing or have a compacted bulk density greater than 55 lbs/ft 3 (880 kg/m 3 ). If using bin jacks during assembly, always lift on an upright. Choose a hoist with a adequate capacity for the expected empty bin deadload. Make sure the rated capacity of the hoist is not exceeded. 3.5. Cutting Openings in Wide-Corr Grain Bins This section provides instructions for cutting openings to accommodate fan transitions, unloading augers and roof vents. General Rules for Cutting openings 1. Never cut any uprights, roof ribs, or wall sheet bolted vertical seams to create an opening. 2. Openings shall be located so equipment being installed won't interfere with any bin components/ accessories. 3. Openings shall be minimized as much as possible for structural integrity of grain bins. 4. Corners in openings shall be cut with minimum radius of 1/8" to reduce stress concentration. 5. Openings shall be sealed all the way around for all weather conditions. 6. Instructions shall be followed closely to avoid damage to bin structure. 7. Except cutting openings described below, any other modification to Westeel bins shall be approved by a professional engineer. 198864 R11 9

3. BEFORE YOU BEGIN FARM SERIES EXTENSION TIER 15-48 WIDE-CORR GRAIN BIN Openings for Fan Transitions of Aeration Floors 1. Consult aeration floor installation instructions for information on Planning floor layout. 2. Openings shall be centered to a wall sheet in horizontal direction. 3. Opening shall be cut as tight as it can be for the transition to go through and shall have no more than 1/4" gap on any side to the section of a fan transition going through a bin wall. 4. Opening height for fan transition shall be limited to 12.5" inches from bottom edge of a bottom wall sheet. 5. Opening width shall not exceed 46.5" for stiffened bins and 72.5" for unstiffened bins. 6. Vertical support shall be required to support load above opening. 7. Bottom angles may be cut flush to the sides of an opening to form part of opening. Openings for Unloading Augers of Wide-Corr Bins with Full Floor Aeration 1. Consult aeration floor installation instructions for information on Planning floor layout. 2. Openings shall be centered to a wall sheet in horizontal direction. 3. Openings shall be cut as tight as it can be for unloading auger to go through and shall have no more than 1/ 4" gap to auger flange section on any side. 4. Opening height for any auger shall be limited to 12.5" from the bottom edge of a bottom wall sheet. 5. Vertical flange of a bottom angle may be cut flush to sides of an opening to form part of opening. Openings for Roof Vents in Roof Sheets 1. Openings shall be centered between roof ribs and have 2.5" minimum distance between edge of opening and base of a roof rib. 2. Openings can be square, rectangular, or round. 3. Openings shall be the same size as the inlet opening of a vent being installed. 4. Any side of a square/rectangular opening shall have a maximum length of 18" and a circular opening shall have a maximum diameter of 24". 3.6. Critical Assembly Requirements To ensure a successful, safe and reliable outcome you must comply with the following assembly techniques and practices: 1. Comply with all local code and jurisdictional requirements applicable to your extension tiers installation. 2. Design and build foundations with the necessary strength for the loads they must support, and for local soil conditions. Westeel foundation guidelines are based on specific stated conditions and may not be applicable to local conditions. 3. 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 a) grouting under the bottom ring of a non-stiffened bin or tank, and b) shimming under the uprights of a stiffened bin or tank, or under the legs of a hopper. 4. 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. 10 198864 R11

FARM SERIES EXTENSION TIER 15-48 WIDE-CORR GRAIN BIN 3. BEFORE YOU BEGIN 5. Comply with all assembly instructions provided in the appropriate assembly manual to make sure your whole extension tiers is constructed safely. Important: Do not deviate from the wall sheet and upright layouts provided. 6. 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. 7. When installing roof stiffening rings, if it is necessary to shorten the stiffening ring tubes, shorten them as little as possible. Initially the nuts on the expanders should be centered and as close together as possible. When tightening, share the amount of take-up between expanders such that the nuts remain centered, and the amount of engagement between all expanders on the same ring is equalized. 8. If extending an existing bin or tank, ensure that the foundation is adequate for the increased loads it must support. 9. If installing an existing bin on a hopper, make sure the bin is designed for a hopper application, and that the foundation is capable of withstanding the substantial point loads that the hopper legs apply. If uprights are present, make sure that they are supported. 10. Make sure that an integral end-to-end connection exists between all mating uprights. Successive uprights must not overlap. 11. Vertical tolerances between uprights and wall sheets are tight. This can be affected by jacking techniques, which can allow the tolerance to grow or shrink depending on the technique used. The gapping between successive uprights must be monitored to ensure that upright holes align with wall sheet holes. 12. If catwalks are being installed on the structure, upright catwalk upgrades are likely required. The upgraded stiffeners must be installed in the correct locations to support the intended catwalk loads. Also, the structure must be properly oriented to ensure the eventual correct alignment between the catwalks and the supporting uprights. Finally, the connectors that tie into the uprights and support the catwalks are best installed during assembly of the structure. See the catwalk assembly manual for additional details. 3.7. 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 2 on page 12.) 198864 R11 11

3. BEFORE YOU BEGIN FARM SERIES EXTENSION TIER 15-48 WIDE-CORR GRAIN BIN Store curved wall sheets hump-up. (See Detail A in Figure 2 on page 12.) All other bundles material should be placed so that they are well sloped to promote good drainage. (See Detail B in Figure 2 on page 12.) Roof sheets must be elevated at least 12" at the small end of the sheets. (See Detail B in Figure 2 on page 12.) Temporary storage can be provided by erecting a simple framework supporting a waterproof tarp. (See Detail C in Figure 2 on page 12.) 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. Figure 2. Product Storage A B C D If Parts Become Wet 1. If parts become submerged or wet, the bundles should be opened as soon as possible, sheets or material separated and dried. Keep separated until assembly. Brace parts properly so as to avoid damage or injury from material falling when in storage. (See Detail D in Figure 2 on page 12.) 2. Any boxed parts that become wet should be dried and stored in a new box that is free of moisture. 3. In addition to wiping down wall sheets, 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. 3.8. Grain Bin Use 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. 12 198864 R11

FARM SERIES EXTENSION TIER 15-48 WIDE-CORR GRAIN BIN 3. BEFORE YOU BEGIN 3.9. Important Notes Westeel does not provide a foundation design for this product, and is not liable for any damages or injuries related to inadequately designed or constructed foundations. Customers must contract professional services for all foundation design and construction work. For information on foundation design requirements, refer to Section 3.2. Foundation Design and Loads on page 8. In order to maintain your wall sheets in good condition separate sheets and allow air circulation between them. Store sheets in a dry place. Do not store sheets with sheet ends pointing upwards. To keep an even pressure on walls, the bin must always be unloaded from the centre. Contact local power officials for minimum power line clearance. See Section 3.6. Critical Assembly Requirements on page 10 for mandatory siting and assembly requirements. Store only non-corrosive, free-flowing materials up to 55 lbs/ft 3 (800 kg/m 3 ) average compacted density in Westeel bins. Tighten all bolts to the recommended torque settings. Do not locate grain bins close to high buildings, which might cause snow to fall onto or build up on the roof of the grain bin. Consider future expansion and allow space for loading and unloading of the bin. Your dealer and local government agricultural consultants can help you plan your storage system for maximum efficiency. 198864 R11 13

4. PREPARATION FARM SERIES EXTENSION TIER 15-48 WIDE-CORR GRAIN BIN 4. Preparation 4.1. Check Shipment Unload the parts at the assembly site and compare the packing slip to the shipment. Ensure that all items have arrived and that none are damaged. Report damaged parts or shortages immediately to the delivering carrier, followed by a confirming letter requesting inspection by the carrier, if required. Order any replacement parts immediately to ensure that assembly will not be held up by missing parts. All parts will be charged for and credit will be issued by party at fault. No credit will be issued if freight bills are signed as received in good condition. 4.2. List of Tools and Equipment Use quality tools and equipment. Use them safely, and correctly, for their intended use. Tools for this application should include: Tools Electric or pneumatic (air) impact tools Power drill and drill bits Sockets (multiple 9/16" and 1/2" sockets recommended) Large-pocket carpenter pouch 8" (20 cm) metal punches (for aligning bolt holes) Step and extension ladders, construction grade 6-point wrenches (Imperial, box end) Metal-cutting saw suitable for cutting roof rings and wind rings Scaffolding Centre-post bin stand Crane and/or bin jacks Minimum Recommended Safety Equipment A properly-stocked first-aid kit Eye, foot, head, and hand protection (safety glasses, steel-toed boots, hard hat, work gloves) Cable, chain, or rope to tie-off bin or jacks in case of wind Body harness and lifeline (for use where falling hazard exists) Ground fault interrupt protected electrical hook-ups 4.3.

FARM SERIES EXTENSION TIER 15-48 WIDE-CORR GRAIN BIN 5. ASSEMBLY 5. Assembly 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 extension tiers. 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. 198864 R11 15

5. ASSEMBLY FARM SERIES EXTENSION TIER 15-48 WIDE-CORR GRAIN BIN 5.2. Prior to Construction To maintain your extension tier wall sheets in good condition, separate sheets and allow air circulation between them. Store sheets in a dry place. Do not store sheets with sheet ends pointing upward. Check foundation and soil capacity for suitability of the proposed extension. Refer to the Foundation Design section in the Wide-Corr Grain Bins Farm Series Manual 198862. Plan for the required accessories which will be affected by the extension eg., longer ladder, longer auger, larger aeration fan, additional aeration floor supports etc. In addition to the extension tier parts, be sure to order additional sheets and/or bottom ring angles, if necessary, to replace any damaged or previously modified components, eg. cut for aeration transition. Check the Door Installation section in the Wide-Corr Grain Bins Farm Series Manual 198862 to see if the planned extension puts the bin in an auger chute restricted size. If you are extending to a 2408, 2706, 2707, 2708, or 2709 and your present bin has an auger chute you will have to order Door Board 235126 (if original bin is from 2004 and earlier) or Door Board 236831 (if original bin is from 2005 and later) and replace the auger chute. 5.3. Installation Instructions 1. Re-construct the bin to its final form, matching the appropriate layout shown in the Wide-Corr Grain Bins Farm Series Manual 198862. The Wide-Corr manual is found in the WC Extension Tier Hardware Pail 235017. 2. Install the new sheets as shown in the Wall Sheet and Bottom Angle Assembly section of the Wide-Corr Grain Bins Farm Series Manual 198862. 3. Remove the old caulking around the door and the re-used short sheet. 4. Clean the surface and re-caulk. 5. Use the 3/8 x 1 bolts for all wall sheet seams. 6. Use the 3/8 x 1 ¼ bolts from the WC Extension Tier Hardware Pail around the door. 7. Use the 3/8 flat washers to re-attach the bin to the bottom angle. Because of design changes over the years, you must use the new short sheets provided in the extension kits, even if you have an existing short sheet with the same part number and gauge designation. Current wall sheets are manufactured from higher-grade steel than used prior to 2001. In the case where only one short sheet is provided and it is to be used with an existing short sheet of the same gauge, the new short sheet must be installed in the bottom tier. Important If the horizontal bolts in the bottom sheets of the existing bin are spaced at 9 3/8 and you are extending up to 12 gauge sheets or heavier (p/n 194685) you need to consider the bottom angles and sealform connection. If you haven t replaced the 2004 or older bottom ring angles (slots spaced at 3 1/8 ) with the 2005 or newer bottom ring angles (slots spaced at 4 11/16 ), you will need to drill through every second hole of the bottom wall sheet horizontal seam into the old bottom angle with a 7/16 drill bit. The spacing after drilling should be 4 11/16. Fill the holes with 3/8 hardware. You will have to drill out a 2004 and older sealform and thrust ring in the same way. 16 198864 R11

5. ASSEMBLY FARM SERIES EXTENSION TIER 15-48 WIDE-CORR GRAIN BIN 5.6. Bin Roundness It is imperative that the bin be as round as possible. The following steps describe how to ensure the bin is round. 1. Verify that the foundation meets all the requirements of the installation. 2. Scribe the bin circumference onto the foundation as follows: a. Anchor a string to the exact center of the concrete foundation. b. Consult the following table to find the scribe radius for the size of the bin being assembled. c. Using the required string length, scribe the bin circumference onto the foundation. The radius values given in the chart are 3/4 inch smaller than the wall sheet radius at the bottom. This ensures that the scribed circle can be seen during assembly. A perfectly placed ring of sheets should be 3/4 inch on the outside of this scribed circle. 3. After the first ring of wall sheets has been assembled, check the position and roundness of the ring: a. Verify that the maximum amount that the bin is out of round is no more than 0.75 " on the radius, when measured from the center of the bin. b. Verify that the wall sheets form a smooth circle with no flat spots or cauliflower shaped curves. c. Before anchoring the bin to the foundation, re-check to ensure that the bin is round and within tolerance. Correcting for roundness becomes much more difficult the longer you wait. 4. Locate anchor bolts towards the outside of the anchor bolt slots (away from bin) to permit the incremental expansion that can occur with the initial filling of the bin. 5. When setting jacks, make sure they are also set round and that they are anchored to the concrete. Table 5. Scribe Radius 15 to 54 Bins Nominal Bin Dia. Scribe Radius Nominal Bin Dia.
