Know which days your crews can pour, lift and work at height
Weather is the biggest cause of delay on site. weatherAI.io turns the forecast into a go/no-go for each task, with the hours that work and the risks that don't, so you can plan pours, lifts and roof work days ahead and move crews before the rain arrives.
What you can do
- Schedule concrete pours around frost, rain and fast-drying heat
- Plan crane lifts and work at height around wind and gusts
- Warn site managers the evening before when tomorrow turns bad (alerts)
- Set your own limits, e.g. gusts under 38 km/h for a specific crane (custom rules)
Activities in this pack
Pouring concrete
activity=concrete-pour · windows of 6 h or moreA pour and the first hours of curing: air above 5°C (no frost), no rain, not too hot or windy (fast drying cracks the surface).
Crane lifts
activity=crane-lifting · windows of 2 h or moreLifting with mobile or tower cranes: mean wind and gusts decide (wind is stronger at height than these 10 m figures), then storms, ice and poor visibility. A planning guide only: always follow the crane's and the lift plan's wind limits.
