Protect your crews, keep your deadlines
Geolocated storm alerts site by site, not across the whole region. Decide to stop what must stop, and keep the rest running.
A storm on a construction site: safety first, productivity second
A construction or civil-engineering site is, by nature, one of the environments most exposed to storm risk. Workers operate outdoors, often at height, frequently near metal structures or conductive equipment. Cranes, aerial lifts, scaffolding, cables: every part of an active site becomes an aggravating factor when lightning threatens.
This isn't just common sense. It is a legal obligation.
French Labour Code, article L5424-6: the employer can and must stop a site when weather conditions make the work impossible or dangerous for workers' health and safety. The construction bad-weather scheme provides compensation for laid-off workers, covered by the Congés Intempéries BTP funds.
The problem with current alerts for site managers
An HSE manager running several active sites across several departments faces a structural information problem with the free tools available.
Alerts too broad
An orange warning over a whole department doesn't say which specific site is exposed. Stopping everything creates unjustified costs. Stopping nothing leaves you exposed.
Wrong timing
Lowering a 40 m aerial lift, securing a crane, sheltering materials: these take time. An alert at 15 km doesn't leave time to act.
No trajectory
Will it hit the Bordeaux site or drift north? Without a trajectory, the shutdown decision falls back on maximum caution, meaning unjustified stoppages.
What Storm Predict changes for construction
Site-by-site monitoring
Storm Predict lets you set up each active site as an independent monitoring spot. The platform tracks storm cells in real time and triggers an alert only when a phenomenon threatens a precise site, with accuracy under 10 km.
If you run six sites and a storm episode is approaching, you know in real time which sites are on the trajectory and which can keep working normally.
Alerts differentiated by phenomenon type
Immediate stop of work at height, shelter for personnel, parking machinery away from tall structures.
Risk to materials stored in the open, unprotected sensitive equipment, personnel without adequate protection.
Objects falling onto scaffolding, light materials shifting, risk to lifting equipment depending on wind thresholds.
Four hours of lead time to organize operations
With predictive trajectories up to 4 hours, Storm Predict gives you time to organize a safe shutdown without pressure. This window lets you plan the orderly lowering of aerial lifts, shelter sensitive materials, inform teams and subcontractors, trigger documented shutdown procedures in line with the construction bad-weather scheme, and reschedule deliveries planned during the risk window.
A planned, organized shutdown costs less than an emergency one. And it is incomparably safer.
Multi-site management and subcontractors
A centralized dashboard for the HSE manager
Storm Predict centralizes information in a single dashboard. Every configured site is visible at once, with its real-time risk status. A glance is enough to see which sites are in the danger window.
Co-activity and subcontractor coordination
A large site isn't run by a single company. When a storm threatens, the shutdown decision must be coordinated with everyone present. Storm Predict lets you designate several alert recipients per site: the site manager of the main contractor is alerted at the same time as the leads of the main subcontractors. Delivery is simultaneous, not sequential.
Site deadlines and the bad-weather scheme
The construction bad-weather scheme includes an often-overlooked mechanism: the option to request an extension of the works deadline equal to the number of bad-weather days actually recorded, on top of the foreseeable days set in the contract documents. Storm Predict provides a timestamped history of alerts for each configured site, useful to document the conditions behind shutdown decisions.
The economic case: stop what you must, keep the rest running
An unjustified shutdown has a real cost: crews paid to wait, schedule delays, possible penalties. A late or insufficient shutdown exposes you to accidents, regulatory procedures and costly material damage.
Storm Predict's value lies precisely in differentiation. By knowing which sites are genuinely exposed, the site manager makes the shutdown decision where it's needed and keeps activity going where the risk is nil. Over a season, this precision generates direct savings on non-productive hours and avoided losses.
Service limits
Storm Predict is not a substitute for official Météo-France records, which remain the regulatory reference for construction bad-weather declarations. It only addresses the weather side of site safety. A confidence index is shown on every predictive trajectory.
