Contract-Ready Weather Claims Evidence
Automated, auditable evidence packages for NEC4 compensation events, JCT extensions of time, and FIDIC climatic conditions claims. Accepted by adjudicators.
Weather Claims Fail Without Proper Evidence
Contractors lose weather claims not because the weather wasn't bad enough, but because they can't prove it was. Manual weather data collection is inconsistent, easily challenged, and rarely meets the contemporaneous evidence standards that adjudicators require.
By the time a claim is prepared, the evidence trail has gaps. Site diaries are incomplete, weather station data doesn't match the project location, and there's no systematic comparison to contractual baselines.
How It Works
Four steps from automatic recording to adjudicator-ready evidence packages.
Automatic Recording
WeatherWise records weather conditions at your site daily from the moment your project starts. No manual input required.
Threshold Flagging
The system automatically flags days when conditions breached your activity thresholds, building a continuous record of weather-impacted days.
Generate Evidence
Generate evidence packages on demand: daily records, threshold breach reports, historical comparisons, and 1-in-10 year baseline analysis.
Export for Disputes
Export auditable PDF evidence reports formatted for adjudicators and arbitrators under NEC4, JCT, FIDIC, and ICC frameworks.
Key Features
Everything you need to build and defend weather claims under major contract frameworks.
Automated Daily Recording
Continuous, automated weather data capture at your site coordinates. No reliance on manual site diaries or distant weather stations.
NEC4 Compensation Events
Evidence formatted for NEC4 Clause 60.1(13) weather compensation events, including 1-in-10 year baseline comparisons at your site location.
JCT Adverse Weather
Analysis supporting JCT Clause 2.29.9 extensions of time for adverse weather conditions, with statistical evidence of conditions being exceptionally adverse.
FIDIC Climatic Conditions
Evidence for FIDIC Sub-Clause 8.5 unforeseeable climatic conditions claims, with historical baseline comparisons demonstrating conditions beyond reasonable expectation.
1-in-10 Year Baselines
Automatic comparison of actual conditions against 1-in-10 year baselines calculated from 45+ years of ERA-5 data at your exact site coordinates.
PDF Evidence Reports
Generate professional, auditable PDF reports on demand. Formatted for adjudicators and arbitrators with clear data visualisation and statistical analysis.
