WeatherWise by the numbers
Construction is Still Running on Gut Feel
45% of all construction projects are delayed by weather, costing billions in overruns, disputes, and margin erosion. Yet most contractors still guess at weather risk with arbitrary percentage allowances.
You pad your programmes with round numbers. You argue about what counts as 'exceptionally adverse.' You lose claims because you can't prove what the weather should have been. There's a better way.
Weather Intelligence That Speaks Construction
WeatherWise doesn't give you weather forecasts. It gives you construction answers.
Weather Calendars
Day-by-day working/non-working logic for every activity on your programme. Know exactly which days are workable based on 45+ years of data.
Learn more →QSRA Integration
Probabilistic delay distributions that drop straight into your Acumen Risk or Safran Risk model. Weather becomes a calibrated input alongside your other risks.
Learn more →Claims Evidence
Time-stamped exceedance records that prove exactly when conditions breached your thresholds. Ready for NEC4, JCT, and FIDIC disputes.
Learn more →Forecasting & Alerts
14-day lookahead forecasts calibrated to your activity thresholds. Know which days will breach your limits and resequence before the weather hits.
Learn more →Monte Carlo Modelling
Move beyond deterministic schedules. Generate P50, P80, and P95 completion scenarios with probabilistic weather simulation.

Real Results from Real Projects
27 days saved, ~£59M impact
£4B HVDC transmission link. WeatherWise + Acumen Risk integration identified hidden risks and enabled schedule compression from ECI stage.
108 additional risk days identified
Hospital in Canada's Far North. First EHAB-Safran integration pilot shifted P80 end date by 4 months, protecting both parties.
New QSRA weather standard adopted
Multi-billion pound motorway programme. WeatherWise established the standard for quantifying weather in QSRA across 6+ tier-1 contractors.
34% of time risk attributed to weather
15 projects across Transportation, Water, and Aviation. Weather risk quantified, justified, and accepted by clients for the first time.
What Construction Leaders Say
"EHAB is integral to our risk management, guiding decision-making from preconstruction through delivery. Saves days of manual weather analysis."
"We use EHAB in QSRA sessions to model weather risk precisely, giving greater assurance on milestones and helping explore ways to de-risk."
"EHAB's weather model is the Rolls Royce of weather risk management. For schedule risk analysis, this is the way to go."
"Makes it easy to assess historical, current, and forecast weather data against contract terms—leading to more economical programmes."
"EHAB taps into weather data to provide consistent downtime analysis. A prime example of new tech we're using at BAM."
"Helps us assess and mitigate weather risks using extensive historical data and location variables—critical for accuracy."
