Weather intelligence built for the people who run construction projects — not for meteorologists.
Construction Weather is a specialist platform that translates raw weather data into construction-relevant decisions. Every tool on the platform is designed around the language and workflows that project managers, quantity surveyors, site engineers and contract administrators actually use.
The platform covers five areas: trade-level forecasting, historical data retrieval, EOT weather evidence, early warning notice drafting, and tender-stage unsuitable-day planning. Each tool connects directly to the same underlying weather dataset, so the numbers are consistent across your whole project record.
Construction Weather is an independent software platform. It is not affiliated with Cordulus or any on-site weather hardware provider.
Weather is one of the most common sources of delay disputes in construction, yet the tools contractors reach for — generic weather apps, spreadsheets, downloaded CSV files — were not designed for contractual use. They produce outputs that are hard to interpret, inconsistent with contract standards, and poorly suited to formal notices or extension-of-time claims.
Construction Weather was built to close that gap: weather data presented in the format that contracts, programmes and project teams actually need.
Five tools, one consistent dataset, built around construction workflows.
14-day forecasts mapped to 29 construction operations, with standards-referenced unsuitable-day thresholds for each trade type.
