Use the Iowa Deflection Formula (modified by ASCE 20-96): Δy (%) = (DL * K * Wc * 100) / (144 * PS + 0.061 * E') Where E' is the soil modulus of reaction (depends on bedding type). The standard provides lookup tables for E' values. Use the Iowa Deflection Formula (modified by ASCE

| Parameter | Tolerance | |-----------|-----------| | Plumbness (vertical piles) | 1% of length (max 2 inches per 10 ft) | | Horizontal alignment | 3 inches at cut-off elevation | | Tip elevation (friction piles) | ±4 inches | | Tip elevation (end-bearing) | ±1 inch | : Provides methods for determining the strength requirements
