WHY IT EXISTS

Why This Tool Exists

The Problem

Construction teams manually estimate weather risk using generic forecasts and past experience, missing specific activity-level impacts. This leads to unrealistic schedules, schedule disputes, compensation claims, and costly weather-related delays that are difficult to prove and justify.

The Solution

Quantifies weather risk with 92.3% accuracy by running 45+ years of location-specific climate data against project schedules. Provides day-by-day weather calendars, probabilistic delay distributions (P50/P80/P95), and forensic evidence for contract compensation claims under NEC4, JCT, and FIDIC frameworks.
