Overview

Based on DDC methodology (Chapter 2.2), this skill integrates open construction datasets from various sources like government databases, industry benchmarks, weather services, and geospatial data.

Common Use Cases

Fetch Material Prices

integrator = OpenDataIntegrator(region="US")
Get material price indices
result = integrator.fetch_data("material_prices", {
    "materials": ["concrete", "steel", "lumber"]
})
print(f"Fetched: {result.records_fetched} records")
for record in result.sample_data:
    print(f"  {record['material']}: index={record['current']}, trend={record['trend']}")

Enrich Project Data

project = {
    "name": "Office Building",
    "materials": ["concrete", "steel", "glass"],
    "trades": ["carpenter", "electrician", "plumber"],
    "location": {"lat": 40.7128, "lon": -74.0060},
    "start_date": date(2024, 6, 1),
    "end_date": date(2024, 12, 31)
}
enriched = integrator.enrich_project_data(project)
print(f"Sources used: {enriched.sources_used}")
print(f"Confidence: {enriched.confidence:.0%}")
print(f"Material indices: {enriched.enrichments.get('material_price_indices')}")

Assess Weather Risk

risk = integrator.get_weather_risk(
    lat=40.7128,
    lon=-74.0060,
    start_date=date(2024, 6, 1),
    end_date=date(2024, 8, 31)
)
print(f"Risk Level: {risk['risk_level']}")
print(f"Rain Days: {risk['rain_days']}")
