Know your site's air, moisture and gas — from slab to handover.
A construction site changes week to week, and so do its risks — gas where services are cut and capped, moisture where walls are closing in, and a handover where the record usually disappears. It's as true of a bridge pour or a tunnel fit-out as it is of a tower. SapienOS monitors the build as it happens, and hands the operator the data along with the keys.

The risks move with the programme
Gas on a live site
Services get cut, capped and rerouted constantly — on building sites and civil works alike — and methane doesn't wait for the next handheld sweep. Periodic checks tell you about the moment of the check — not the hours in between.
Moisture sealed into the fit-out
Wet trades, weather and programme pressure mean slabs and frames get lined before they're dry. The mould claim that follows arrives years later, with no record of what was sealed in.
Handover without a record
The operator gets manuals and warranties, but the building's actual conditions during construction vanish — right when defect-liability questions need them most.
Monitoring that follows the build
Gas monitoring, industrial heritage
SapienOS grew out of industrial methane sensing, and it shows: continuous methane monitoring with alerting to site management — backing up your safety procedures between formal checks, never replacing them.
Moisture through the fit-out
Temperature and humidity tracked in the zones being closed in, so you know what was dry before it was lined — and can hold the programme where it wasn't. The same record follows a civil pour: conditions around curing concrete, measured rather than assumed.
A handover data pack
The building's measured record — gas, moisture and environmental conditions through construction and commissioning — packaged for the operator, with every reading authenticated with a per-device key and signed at the gateway.
Structural monitoring
Vibration and structural health monitoring on the same platform is in development — on the roadmap, not available today. Instrument a site now and the modular hardware is built to grow into it.
In developmentLive during the build, evidence after it

Live site dashboard
Gas and environmental conditions across the site in one browser view — what's normal, what's drifting, and what tripped an alert.
Alerts that find the site manager
When methane trends up or a zone drifts, the alert carries the location, the readings and the AI's advisory context — so the response starts informed.
Evidence that outlives the build
When the mould question or the defect claim arrives, you open the pack: per-zone moisture history, the gas event log and conditions at commissioning — timestamped measurements, not recollections.
