When construction takes place near existing structures, or an asset is showing signs of movement, you need reliable data. MatMap provides precise monitoring surveys that measure 3D movement and deflection over time, to millimetre level where needed. Our monitoring helps engineers, asset owners and contractors manage risk, prove compliance and act early if trigger levels are approached.
What we monitor
- Retaining walls, embankments and cuttings
- Bridges, culverts and highway structures
- Railway track and adjacent infrastructure
- Party walls and neighbouring buildings during excavation or piling
- Basements, temporary works and sheet piling
- Settlement of slabs, foundations and tanks
- Historic structures vulnerable to vibration or ground movement
Monitoring methods
Monitoring starts with stable reference points, located well outside the zone of influence and set up as part of a rigorous control network. We then take repeated precision observations to targets on the structure using high-accuracy total stations and precise digital levels. Where a full-surface comparison is more useful than individual points, we use 3D laser scanning.
Every epoch is processed, quality-checked and compared with baseline readings and your agreed trigger levels: green, amber and red. If movement approaches a threshold, we tell you straight away.
Monitoring reports
- Baseline and periodic monitoring reports
- Movement tables and time-displacement graphs for every target
- Trigger level (green, amber, red) alerts
- Plans showing target locations and movement vectors
- Data in formats to suit your engineer’s analysis
Sectors we support
Our monitoring surveys support infrastructure owners, construction contractors, heritage property managers and public sector estates.
