Construction environmental monitoring

Keep the neighbours — and the regulator — on your side

Roadworks and building sites shake, dust and roar. Regulations set hard limits on vibration, dust and noise, precisely so nearby homes don’t crack and people aren’t harmed. Senmos watches all three live, across every neighbouring property, and raises the alarm the instant a limit is approached.

One rulebook, three limits

Compliance and protecting your neighbours are the same job. The thresholds in the regulations exist to stop nearby buildings cracking and to spare residents from harmful dust and noise — so staying under them keeps you legal and keeps the people next door safe. Senmos turns that one rulebook into live, per-property limits with automatic alarms.

“We are personally using this platform and it’s impressive what it can do, hopefully much more to come.”

How a construction zone is instrumented

Picture an active construction zone with the 5–10 nearby properties around it. Every property carries the same monitoring point — vibration, dust and noise together — so you watch all three sensor types at once. Impact falls off with distance from the works, so the closest, most vulnerable buildings get the tightest limits.

CONSTRUCTION ZONE closest · highest impact furthest · lower impact Every property measures all three: Vibration – PPV (mm/s) Dust – PM10 / PM2.5 Noise – dB(A) faint rings = falling impact with distance from the works
Figure — A plan view of the works: the construction zone on the road and the nearby properties around it, each carrying the same vibration + dust + noise monitoring point. Closer buildings get the tightest limits.

Sensor-to-screen, live at every property

Triaxial vibration sensors (PPV)

Measure peak particle velocity in mm/s on or beside each building — the number that tells you whether the structure is at risk.

Dust / particulate sensors (PM10 / PM2.5)

Track airborne dust concentration in real time, so air-quality limits are met and complaints can be answered with data.

Sound-level meters (dB(A))

Continuously log noise at the property line against the permitted day/evening/night limits.

Per-property thresholds + automated alarms

Each property gets its own limits based on distance and building type, streaming live into Senmos — an alert fires the moment a limit is approached.

Why each one matters

Three simple stories, one platform. Each measurement protects something specific — and each one trips an alarm in Senmos the moment it crosses the limit.

VIBRATION cracks open between the bricks ground-borne vibration PPV limit exceeded DUST fills the air – air quality & health PM10 limit exceeded NOISE from heavy equipment on site limit exceeded Live level vs limit – same logic for all three 0 limit alarm the live trace climbs; the moment it crosses the red limit, Senmos fires the alarm and logs it
Figure — Three things to watch, one safety logic. Vibration shakes the ground and opens cracks between the bricks of nearby walls; dust drifts off the works and fills the air; heavy equipment fills the area with noise. Each is measured at the property and, the moment it crosses its limit, Senmos raises the alarm — exactly where the live trace meets the line.

What this looks like in Senmos

The dedicated environmental demo — vibration, dust and noise across a street of properties — is being built. The views here come from live Senmos demo projects, and the platform behaviour is the same. In Senmos you can:

See every monitored property

The street map with all 5–10 properties pinned, each showing its current vibration / dust / noise status.

Track vibration against its limit

Open one property’s PPV history and see exactly how close it has come to cracking risk.

Follow dust & noise trends

Particulate and dB(A) trends over the day, against the permitted limits.

Review the alarm log

Every threshold breach, when it happened and at which property — your audit trail for the regulator.
