Key Takeaways
- Site Conditions Matter: Geotechnical investigation prevents foundation problems.
- Access Requirements: Truck and equipment access affects layout.
- Utilities Availability: Power, water, and drainage connections.
- Regulatory Compliance: Zoning, environmental, and safety requirements.
- Future Expansion: Reserve space for potential growth.

Site Assessment
A cement plant in Peru built their silo on what appeared to be solid ground. After installation, they discovered it was fill material that settled 40mm differentially. The $200,000 foundation repair could have been prevented with a $10,000 geotechnical investigation. That experience taught us: never skip the site investigation.
Site investigation scope: Geotechnical borings to determine soil bearing capacity. Groundwater level assessment. Topographic survey for drainage planning. Environmental assessment for contamination. Archaeological survey if required by local regulations.
Layout Considerations
Truck access: Design roads for 40-ton truck traffic. Provide adequate turning radius (minimum 12m). Plan for queuing space during peak delivery. Consider weighbridge location. Ensure all-weather road surface.
Equipment access: Allow space for maintenance vehicles. Provide crane access for component replacement. Plan for emergency vehicle access. Consider future expansion equipment needs. Maintain clearances for safe operation.
Infrastructure Requirements
Electrical power: Calculate total connected load (motors, heating, lighting). Determine supply voltage and phase requirements. Plan for backup power if needed. Include 20% capacity margin for future loads.
Water and drainage: Fire water supply if required by code. Stormwater drainage from site. Washdown water supply if needed. Oily water separation for equipment areas. Connect to municipal systems or provide on-site treatment.
Regulatory Requirements
Planning and zoning: Verify silo is permitted in zoning district. Check height restrictions and setback requirements. Obtain building permit before construction. Address any neighbor concerns early.
Environmental compliance: Dust emission controls per local regulations. Noise limits for equipment operations. Stormwater management plan. Waste disposal during construction. Environmental impact assessment if required.
Frequently Asked Questions
Q: How deep should geotechnical borings go?
A: Typically 10-15m depth or 2x the silo diameter, whichever is greater. Poor soils may require deeper investigation.
Q: What is the minimum distance between silos?
