2. Safety
Proper Storage of Grain Bin/Silo Materials Prior to Construction
Wet storage stain (rust) will develop when closely packed bundles of galvanized material, such as sidewall and roof sheets, have moisture present. Inspect roof and sidewall bundles on arrival for any moisture. If moisture is present, it must not be allowed to remain between the she ets. Separate the sheets or panels immediately and wipe them down. Spray with a light oil or diesel fuel.
If possible, sidewall bundles, roof sheets and other closely packed galvanized materials should be stored in a dry, climate controlled building. If outdoor storage is unavoidable, the materials should be stored so that they are raised above the ground and vegetation. Any stacking an d spacing mat erials sho uld not be corrosive or wet. Be sure to protect materials from the weather, but permit air movement around the bundles if possible.
Storing roof bundles and sidewall sheets at a slight incline can also help minimize the presence of moisture. Storing the bundles with the center of the dome up (like an arch) is one option for minimizing moisture during storage. Sidewall bundles can also be stored on edge but must be secured so that they do not fall over and cause injury.
If “white rust” or “wet storage stain” occurs, contact the manufacturer immediately about ways to minimize the adverse effect upon the galvanized coating.
2. Safety
General Information
Read this manual carefully. This manual will provide instructions on building the sidewall and stiffeners. You will also need to consult other instructions in building the tank. These include, but may not be limited to:
A stiffener and sidewall gauge layout chart. If such a chart is not included with this manual, contact GSI. Roof instructions must be followed. The roof construction manual (PNEG-1092) will contain instructions
for 60' diameter and smaller bins. See appropriate individual diameter instructions for other diameters. Ladders, roof stairs, roof handrails and other products are covered by separate instruction manuals.
Consult the appropriate accessory manual. Aeration systems and transitions are to be installed according to the instruct ions provided with the system
or transition. Anchor bolt placement details are provided in the GSI Concrete Recommendation Manual (PNEG-318).
See this manual.

2. Safety
Construction Procedures and Lifting Jack Usage
NOTE: The roof and top ring or 2 rings will be installed prior to the beginning of bin lifting/jacking
procedures. Reference all other procedures on sidewall and stiffener installation prior to the start of construction.
1. Consider the starting location of the bin, relative to the location of doors and other accessories. Proper placement of lifting jacks in relationship to anchor bolts could make a difference in final locations. Note that the sidewall sheets will be staggered.
2. The bin is lifted by the use of lifting jacks. Lifting jacks are used to slowly and evenly lift the bin during construction. Lifting jacks must be properly sized and designed to carry all dead and live loads and job site conditions associated with the construction of the bin.
The number of lifting jacks required is best determined by personal experience and expertise. Factors such as bin size, jack design, construction conditions, support surface, etc., are all to be considered when deciding how many to use. If in doubt, use one jack on every sheet. The lifting jack must be adequate to carry all loads. Heavy duty jacks, generally hydraulic or electric powered in the case of large bins, should be used for commercial installation. All jacks should be secured with braces or otherwise maintained in a stable condition.
Lifting of the bins should not be done under windy conditions. Follow the jack manufacturers recommendations on capacity and operations.
3. Lifting brackets must be attached through the stiffener bolt holes. Normally you will need to attach to at least four (4) bolts per stiffener.
4. Raise the bin just high enough to assemble the next ring. When lifting the bin, all jacks must lift at an equal rate. Monitor the lift to ensure even lifting is occurring.
5. To the inside of the first ring, bolt the next ring. Be sure to stagger the sheets and select the proper gauge material.
6. Lower the bin onto the foundation after assembling and tightening bolts on the new ring or rings.
7. Attach stiffeners to the body sheets every two (2) tiers (on the external surface of the bin). You may want to leave sheets loose to make the attachment of the stiffeners easier.
8. Now re-bolt the lifting brackets to the lowest ring in place thus far. Continue ring additions by repeating Steps 5 and 6.
9. Add inside and outside ladders as you continue to raise the bin. (Refer to the manual supplied with the ladder.)
10. Lower the tank and secure to the foundation before leaving the job site.
11. At the completion of the tank, set stiffeners over the anchor bolts and measure the ta nk to ensure it is in a round condition. Consult with GSI for questions on tolerances.
NOTE: For 2 ring doors or vehicle traffic doors special placement issues may apply. Consult the special
instructions provided with 2 ring doors or vehicle traffic doors for these options.
Roof Damage Warning and Disclaimer
Excessive vacuum (or pressure) may damage roof. Use positive aeration system. Make sure all roof vents are open and unobstructed. Start roof fans when supply fans are started. Do not operate when conditions exist that may cause roof vent icing.
DC-969
CAUTION!
The manufacturer does not warrant any roof damage caused by excess ive v acuum or internal pressure from fans or other air moving systems. Adequate ventilation and/or “makeup air” devices should be provided for all powered air handling systems. The manufacturer does not recommend the use of downward flow systems (suction). Severe roof damage can result from any blockage of air passages. Running fans durin g high humidity/cold weather conditions can cause air exhaust or intake ports to freeze.

A strip of caulking 10" long, should be placed along the horizontal seams. Before bolting the next ring into place, apply one strip of caulking 10" long on the front of the underlapped sheet at each joint. Also, a 10" strip of caulking is to be placed along the lower horizontal edge of lapping sheet at every vertical seam.
