Slide 2.1 Concrete vs. Helipost
The Problems with Concrete:
Complicated - Labor intensive and equipment heavy, with
multiple crews necessary to complete the installation process.
Expensive – Inefficiencies due to the common logistical
challenges, materials, and equipment used for concrete
installation add both time and money to the project costs
Slow – The curing period required before concrete piers and
anchors are ready to accept the above-ground unit adds days or
weeks to project schedules.

Slide 4.1 Overview of the Helipost Site Engineering Process
Site Engineering Process Steps
Step 1 – Geotechnical Exploration
Categorize major soil units and determine index properties
Method A: Group soils according to soil classification
Method B: Determine soil index properties through extensive field and laboratory testing
Step 2 – Wind Loads
Determine shear and overturning moment based on structural attributes
Method A: Use AASHTO or ASCE7 wind charts
Method B: Hand calculate wind loads using desired method (see appropriate code)
Step 3 – Helipost Sizing
Determine required foundation size for wind loads
Method A: Refer to Helipost sizing charts for the appropriate soil category
Method B: Apply rigorous limit state and p-y analysis and check foundation strength
Step 4 – Bearing Capacity
Calculate weight of structure to be supported and capacity of foundation
Method A: Refer to Helipost baring capacity charts for appropriate soil category
Method B: Calculate bearing capacity using traditional soil mechanics
Step 5 – Corrosion Measures
Re-adjust sizes if needed to account for corrosion losses over design life
Method A: Observe corrosion chart and adjust size for corrosion category by matching moment and shear while maintaining or increasing size
Method B: Determine corrosion losses and adjust
