Tender review
Understand historical seasonal conditions at the proposed project location.
Project weather records
Historical weather data for construction projects
Retrieve location-based weather records for selected dates and use exports, charts and report outputs to support project reviews.
Build a traceable weather record
Historical records help project teams test recollection and fragmented site evidence against dated, measurable conditions. Select a project location and period, then review the available daily or hourly observations and derived analysis.
- Location and date-range selection
- Daily and hourly weather detail where available
- Rainfall, wind, gust, temperature and snowfall information
- Excel exports for further analysis
- PNG graphics and formatted report material
Useful across project stages
Project records
Supplement site diaries, photographs and daily reports with dated weather information.
Delay analysis
Identify weather dates for comparison with the programme, affected work and contract thresholds.
Evidence should retain its context
When using historical weather in a formal project process, record the selected location, source, period, units, time zone, available observation resolution and any missing information. Confirm whether the contract requires a particular station, source, threshold or statistical method.
Weather records establish conditions, but do not by themselves establish contractual entitlement or critical-path delay. Combine them with notices, contemporaneous site records and programme evidence.
