Slide 1.3 What is the Helipost?
Corrosion and Abrasion Measures
Galvanized in accordance with ASTM-123
Design corrosion rates conform with AASHTO & FHWA-RD-89-186 metal loss rates
Minimal abrasion in 50/6 soil (WSDOT)

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.

Common Helipost Applications
UASUniversal Anchoring Solutions
Slide 3.1 Common Helipost Applications
Introduction: Helipost Applications
Sound walls and noise barriers
Solar panels (ground mounted)
Highway signs
Light posts
Security walls
Cell towers (mono pole)
Steel buildings
Billboards
UASUniversal Anchoring Solutions
Helipost delivers 20 tons of axial load, therefore:
Supports walls up to 30 feet Supports high-mast lights up to 100 feet Supports large exit signs and cantilever lights Supports mono-pole cell towers Anchors even large solar panels
Slide 3.2 Common Helipost Applications
Performance Means Multiple Applications

Overview of the Helipost Site Engineering Process
Step 1 – Geotechnical ExplorationCategorize major soil units and determine index properties
Method A: Group soils according to soil classificationMethod B: Determine soil index properties through extensive field and laboratory testing
Step 2 – Wind LoadsDetermine shear and overturning moment based on structural attributes
Method A: Use AASHTO or ASCE7 wind chartsMethod B: Hand calculate wind loads using desired method (see appropriate code)
Step 3 – Helipost SizingDetermine required foundation size for wind loads
Method A: Refer to Helipost sizing charts for the appropriate soil categoryMethod B: Apply rigorous limit state and p-y analysis and check foundation strength
Step 4 – Bearing CapacityCalculate weight of structure to be supported and capacity of foundation
Method A: Refer to Helipost baring capacity charts for appropriate soil categoryMethod B: Calculate bearing capacity using traditional soil mechanics
Step 5 – Corrosion MeasuresRe-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 sizeMethod B: Determine corrosion losses and adjust
