Construction weather tools across the project lifecycle
Price weather allowances, interpret operational risk, notify project parties and assemble historical weather evidence from a consistent location-based workflow.
Five integrated tools
Each tool addresses a different project decision while reusing location and project information where the application supports it.
Historical data
Retrieve past conditions for a selected project location and export supporting records.
Historical weather data →EOT evidence
Compare a selected month with a five- or ten-year benchmark and organise identified events.
EOT evidence →Tender planning
Estimate average unsuitable days by project month and assigned trade operation.
Tender planning tool →Why weather risk matters at tender →
Early warnings
Create an editable notice draft containing forecast conditions, anticipated impact and proposed mitigation.
Early-warning notices →Live site conditions
Wind, rain and snow at your location — right now
The map below shows animated wind flow and current precipitation at your approximate location using live weather data. The same overlay is available inside the platform for any project site worldwide — helping site teams understand the immediate environment around their site before committing crews.
- Animated arrows show live wind speed and direction
- Rain streaks and snow flakes animate when precipitation is active
- Powered by Open-Meteo real-time data, refreshed hourly
- Works for any construction site location worldwide

Configurable thresholds
Set alert conditions to match your project specifications
Every project has different operational limits — defined by the crane manufacturer, the welding procedure specification, the coating product data sheet or the contract method statement. The notifications system lets you configure project-specific alert thresholds so the platform flags the conditions that matter for your work, not generic defaults.
Wind and gust alerts
Set the wind speed and gust limits relevant to your crane configuration, scaffold design or structural welding procedure — and receive notification before forecast conditions reach your threshold.
Rainfall and humidity alerts
Configure rainfall intensity alerts for planned concrete pours, earthworks compaction, pipeline installation or coating application windows. Set humidity and dew point alerts for blasting, painting or waterproofing work.
Temperature alerts
Set minimum or maximum temperature alerts for concrete placement and curing, mortar setting, coating application or any temperature-sensitive site operation referenced in your specification.
A connected process
Tender. Plan. Notify. Evidence.
Weather risk changes as a project moves from estimating to delivery. A connected workflow reduces the need to reconstruct the story after a delay has occurred.

All sectors
Works across all construction sectors
Weather-related delays and EOT entitlements are not unique to building construction. Civil and infrastructure contractors face identical exposure — and the same contract mechanisms to manage it.
- Building construction — concrete frames, precast erection, structural steel, fitout and finishing trades
- Civil and earthworks — fill placement and compaction suspended by rain, cut-and-fill programmes, roading subbase and kerb work
- Pipeline and utilities — temperature and precipitation limits for joint welding, pipe coating and trench backfill
- Industrial plant — large-scale civil pours (tank bases, reactor foundations), structural welding under wind and humidity constraints
Weather-related EOT entitlements apply to civil contracts under any standard form — NEC4, FIDIC, JCT, AS 4000 or NZS 3910 — in exactly the same way as building contracts. The platform's threshold library covers earthworks, road surfacing and pipeline operations alongside standard building trades.

Not sure which type of platform you need?
Construction weather tools span four distinct categories — field workability apps, on-site hardware stations, enterprise alert systems and contractual workflow platforms. Each solves a different problem for a different user at a different stage of the project.

Common Questions
Platform FAQ
What construction contracts does Construction Weather support?
Construction Weather is designed for use on projects let under NEC3, NEC4, JCT and FIDIC contracts, where adverse weather clauses create entitlement to extension of time or additional cost. The platform's trade thresholds and EOT evidence tools are aligned to how adverse weather is assessed under these standard forms. It is equally suitable for bespoke contracts that reference adverse or exceptional weather conditions.
What tools are included in the platform?
The platform includes five integrated tools: a 14-day trade forecast with operation-specific Green, Amber and Red advisories; a historical weather data retrieval tool; an EOT Evidence Generator that benchmarks a project month against five or ten years of historical data; a Tender Planning tool that calculates average unsuitable days by operation and project month; and an Early Warning Notice generator that produces editable draft notices from forecast data.
How is Construction Weather different from a standard weather app?
A standard weather app tells you it will rain. Construction Weather tells you whether that rain — or wind, frost, heat or humidity — stops the specific operation you have planned. Every tool is built around construction trade operations and contract processes rather than general weather presentation. Outputs are structured for construction decision-making: operational advisories, early warning notices and EOT evidence documents, not forecasts designed for the general public.
Does Construction Weather cover all types of construction trades?
The platform covers more than 20 trade operations including crane and lifting, scaffold erection, steel erection, concrete placement, structural welding, painting and applied coatings, blasting and surface preparation, roofing and waterproofing, masonry, earthworks, road surfacing, piling, glazing and timber framing. Each trade has its own weather threshold set derived from published British Standards, NEC and JCT contract conventions, and CIOB and RICS guidance.
Is Construction Weather available on mobile?
Yes. Construction Weather is a web-based platform that works on any device — phone, tablet or desktop — without downloading an app. It can be added to your phone's home screen in one tap for quick site access.
