CurNext
Structural health monitoring for strain, crack, tilt, and vibration
Trend structural movement before it becomes a claim. CurNext CN-SHM delivers site-integrated monitoring with alerts and evidence in the cloud.
In short
What is structural health monitoring on a construction site?
Structural health monitoring tracks movement and stress indicators such as strain, crack width, tilt, and vibration so teams can trend changes before they become claims. CurNext CN-SHM brings those signals into the same cloud project surface as other site readiness systems.
Why SHM on site
Structural confidence from construction through operations
Continuous watch on the points that matter - integrated into the same CurNext building stack as the rest of the site.
Continuous watch on critical points
Cores, transfers, and temporary-works interfaces get ongoing visibility - not a one-off survey photo.
Threshold events with a timestamp
Burst when limits trip, plus heartbeats for fleet health - so overnight movement is not silent.
Evidence in the project record
Trends and alerts land in CurNext cloud alongside curing, leak, and IAQ - one stack, one trail.
Built for engineering buyers
Site-integrated monitoring with a conservative voice - complements judgment, does not replace consultancy.
The challenge
Movement does not wait for the next site walk
Infrequent checks, thin logs
Crack and tilt rounds are sparse and poorly recorded when something later becomes a claim.
Critical elements go unwatched
Cores, transfers, and temporary interfaces lack continuous attention between site visits.
Loggers sit outside the stack
Standalone devices do not share the same secure path as curing, leak, and IAQ on site.
CN-SHM
Hybrid-cable structural health on the CurNext stack
CN-SHM is a Layer-1 hybrid-cable node for strain, crack width, tilt, and vibration. Battery LoRaWAN with threshold-triggered bursts and scheduled heartbeats. Data joins the CurNext building path for trends, alerts, and project documentation.
Disclaimer: CN-SHM complements engineering judgment. It is site-integrated monitoring within CurNext - not a replacement for structural consultancy or a certified laboratory SHM system, and not an earthquake early-warning product.

What we measure
Strain · Crack · Tilt · Vibration
The channels engineering teams ask for when critical elements need ongoing attention.
Strain
Load paths and member response where design needs ongoing watch.
Crack width
Opening trends on critical joints and interfaces over the project life.
Tilt
Rotation and settlement cues on cantilevers, cores, and temporary works.
Vibration
Dynamic events that static spot checks miss between visits.
How it works
From the member to a clear decision
01
Install
Mount the node and connect the hybrid sensor cable to gauges, crack / LVDT, or tilt-vibration packs per design.
02
Sense
Strain, crack width, tilt, and vibration on one L1 family - continuous enough for site decisions.
03
Connect
LoRaWAN uplink with threshold-triggered bursts and scheduled heartbeats into the CurNext building path.
04
Decide
Trends, threshold alerts, and evidence on curnext.app - for construction through early operations.
Burst + heartbeat
Events when it matters. Heartbeats when it does not.
Carry the events that matter without flooding the network when nothing moves.
Burst on threshold
When limits trip, the node sends promptly so overnight events are not lost.
Scheduled heartbeats
Regular fleet health checks keep the network trustworthy between events.
Built for the site
Industrial by design
- Hybrid cable topology
- Gauges and packs wired to one L1 node.
- Stable uplink
- LoRaWAN EU868 into CurNext.
- Field life
- 5-8 years typical, configurable sampling.
- Factory-fixed purpose
- Structural health - not a field reflash.
FAQ
Structural health monitoring questions
Direct answers for engineers and contractors researching site-integrated structural monitoring.
- What does structural health monitoring measure?
- CN-SHM monitors strain, crack width, tilt, and vibration with threshold-triggered bursts and scheduled heartbeats on the CurNext stack.
- Is CN-SHM a certified laboratory SHM system?
- CN-SHM is site-integrated monitoring within CurNext. It complements engineering judgment and does not replace structural consultancy or a certified laboratory SHM system.
- Can CN-SHM be used during active construction?
- Yes. It is designed for construction environments and joins the CurNext building uplink for trends, alerts, and project documentation.
- Does CN-SHM provide earthquake early warning?
- No. CN-SHM is not an earthquake early-warning product.
- Who should use CurNext structural health monitoring?
- Structural engineers, site managers, and contractors who need continuous movement evidence on critical points during build and early operation.
