From bid to final account
Price it accurately at tender. Plan safely on site. Protect the programme with early warnings. Recover the costs when adverse weather delays the works — including P&G overheads and liquidated damages exposure.
Four stages. One platform.
Construction weather affects every role from the estimator setting the tender allowance to the QS compiling the EOT claim months later. Every stage is connected in a single location-based workflow — so the evidence you build on day one supports the claim at the end.
Use ten years of location-specific historical data to calculate realistic unsuitable-day allowances by trade and project month. Avoid underpricing weather risk — and the P&G overruns that follow when the allowance runs out mid-programme.
Tender team guide →Check whether tomorrow's conditions are suitable for the planned operation before the crew mobilises. Green, Amber and Red advisory grading across 20+ trades — concrete, craneage, roofing, earthworks and more — with a 14-day outlook.
Site manager guide →Issue contractual early-warning notices before adverse conditions arrive. Maintain the contemporaneous weather records that underpin any future delay claim. A 14-day forecast benchmarked against historical norms keeps you ahead of the programme.
Project manager guide →Benchmark the affected project month against a five- or ten-year historical average, identify qualifying weather events, and frame the evidence around the contract clause — NEC, JCT or FIDIC. Build the EOT claim that recovers delay costs and defends against liquidated damages.
QS guide →Most construction weather tools stop at the forecast. Construction Weather is designed around what happens next: the contractual notice, the programme impact, the delay claim. Every output — advisory, early warning draft, EOT evidence pack — is structured for construction decision-making and contract administration, not general public use.
Built for every role on site
Construction weather affects every person on the project — from the site manager planning tomorrow's crew to the QS compiling delay evidence months later. Construction Weather is designed to be useful at every stage and for every role.
Check whether today's or tomorrow's forecast conditions are suitable for the planned operation before mobilising the crew. Green, Amber and Red grading across 20+ trades — concrete, craneage, roofing, earthworks and more.
Daily trade planning →Protect the programme with a 14-day trade forecast, issue contractual early-warning notices before conditions arrive, and maintain the contemporaneous records that support any future delay claim.
Early warnings →Price weather risk accurately at tender using 10 years of location-specific historical data. Build benchmarked, contract-ready EOT evidence when adverse weather delays the works — and recover P&G costs and liquidated damages exposure.
EOT evidence →Built for contractors
Rain, wind, heat and cold affect construction activities differently. The platform connects forecast conditions with selected trade operations, presents Green, Amber and Red advisory levels and provides mitigation guidance.
Integrated tools
Each tool addresses a different point in the project lifecycle — and all share the same location, project and historical dataset so nothing needs to be entered twice.
Construction-oriented risk grading across more than 20 trade operations.
Trade advisories →Review daily and hourly weather records for selected locations and dates.
Historical data →Benchmark weather and organise qualifying events for review — structured around contract wording to support EOT and P&G recovery.
EOT evidence →Compare historic unsuitable-day allowances across project months. Price weather risk accurately so it is in the contract, not absorbed as a loss.
Tender planning →Generate an editable Word draft using project and forecast information — ready to issue before adverse conditions arrive.
Early warnings →Platform outputs support project decision-making and document preparation. They do not determine contractual entitlement, replace programme analysis or constitute legal advice.
Live rain radar
Animated rain radar centred on your approximate location — the same data available inside the platform. Colour intensity shows rainfall rate from light drizzle through to heavy rain. Use it as an instant site check before opening the full construction weather tools.
