Plan tender weather allowances with historical data
Estimate average weather-affected days for selected trade operations and project months at the proposed location.
Move beyond a generic weather allowance
Every project has a different location, season, sequence and combination of weather-sensitive operations. The Tender Planning tool uses ten years of historical information to estimate average unsuitable days for the operation assigned to each project month.
- Set the expected start month, year and duration
- Assign a trade operation to each project month
- Review ten-year average unsuitable days
- Compare adjacent months when considering acceleration or resequencing
- Download information for tender or programme narratives
A transparent planning workflow
Set the location and programme period
Start with the intended project location, expected commencement and duration.
Assign operations by month
Map the planned weather-sensitive trade or activity to each relevant period.
Review historical unsuitable days
Use the calculated averages as evidence for estimating and planning — not as a guarantee of future weather.
Consider programme choices
Compare adjacent months to inform possible acceleration, delay or resequencing decisions.
Planning limitation: Historical averages describe past conditions and do not predict the exact number of unsuitable days a future project will experience. Allow for contract allocation, site exposure, working methods, productivity, climate trends and project-specific tolerances.
