# Settlement Calculator Skill

## Purpose

The Settlement Calculator Skill calculates foundation settlements including immediate (elastic) settlement, primary consolidation, and secondary compression using established geotechnical methods.

## Capabilities

- Immediate (elastic) settlement
- Consolidation settlement (1D theory)
- Secondary compression
- Time-rate of consolidation
- Differential settlement analysis
- Tolerable settlement checks
- Settlement beneath rigid foundations
- Stress distribution calculations

## Usage Guidelines

### When to Use
- Estimating foundation settlement
- Evaluating differential settlement
- Time-rate predictions
- Tolerable settlement verification

### Prerequisites
- Soil compressibility data available
- Foundation loads defined
- Groundwater conditions known
- Soil stratigraphy established

### Best Practices
- Use appropriate stress distribution
- Consider soil variability
- Account for adjacent structures
- Verify with field monitoring

## Process Integration

This skill integrates with:
- Foundation Design
- Geotechnical Site Investigation

## Configuration
