Structural movement monitoring using Leica total stations and fixed monitoring targets.
What Our Movement Monitoring Surveys Provide
Our structural movement monitoring surveys deliver millimetre-accurate 3D data, clear trend analysis and engineer-ready reporting to keep construction and refurbishment projects safe and compliant.
Precise 3D movement data
Millimetre-accurate 3D movement data referenced to a stable control network.
Baseline comparisons
Settlement, rotation and lateral movement identified against baseline readings.
Trigger & alarm thresholds
Pre-agreed trigger and alarm limits defining safe working boundaries.
Clear tables & graphs
Movement tables, vectors and trend graphs for easy interpretation.
Engineer-ready reporting
Reports structured for engineers, project managers and stakeholders.
CAD, PDF & data exports
Outputs supplied in CAD, PDF and data formats for records and BIM.
All monitoring is coordinated to OS or project grid and delivered in formats suitable for design teams, structural engineers and compliance records.
Structural Movement Monitoring Workflow
Scope & Monitoring Strategy
We agree the structures, frequency, trigger levels and reporting format with your team — aligning the monitoring regime with project risk and regulatory requirements.
Installation of Monitoring Points
Survey-grade reflective targets are fixed at key locations on façades, retaining walls and slabs, establishing stable reference points for repeatable measurement.
Regular Site Visits
Our surveyors attend at the agreed interval — weekly, fortnightly or monthly — capturing readings with Leica total stations using consistent, repeatable methods.
Data Processing & Analysis
Readings are processed against the baseline to identify settlement, lateral displacement and rotation across all three axes, flagging trends and potential issues early.
Reporting & Alerts
A clear report is issued after each cycle. If movement exceeds trigger levels, we notify the project team immediately so action can be taken without delay.

When Structural Movement Monitoring Is Required
Movement monitoring is a key control measure on a wide range of construction, refurbishment and asset management projects, including:
Construction near existing buildings and party walls
Monitoring manages the risk of movement to neighbouring properties and supports party wall processes.
Excavations, underpinning, basements and piling
Deep excavations and groundworks often require monitoring of adjacent structures and retaining elements.
Refurbishment of older or sensitive structures
Historic or fragile buildings benefit from tracking movement during refurbishment and strengthening works.
Bridges, retaining walls and temporary works
Critical infrastructure and temporary works are monitored to ensure performance within design parameters.
Buildings with cracking or instability
Monitoring provides an objective record of structural behaviour where cracking or movement is present.
Party wall, insurance and compliance requirements
Movement monitoring supports party wall awards, insurance requirements and statutory compliance.
Monitoring provides evidence-based assurance that structures remain within acceptable limits during and after works, supporting developers, engineers, contractors and property owners.
Reporting & Data Standards
All monitoring reports are professionally structured for immediate use by structural engineers, project managers and stakeholders.
Tabulated readings for every cycle
Clearly referenced and dated readings for each monitoring point and cycle.
Movement in 3D
Easting, Northing and Height movement values reported relative to baseline.
Displacement vectors and plots
Optional vectors, sections and elevation plots to visualise movement across the structure.
Trend graphs over time
Clear trend graphs showing movement behaviour over successive monitoring cycles.
Trigger and alarm summaries
Each report highlights trigger and alarm status and any exceedances clearly.
CAD, PDF and data exports
CAD, PDF and CSV/Excel exports aligned to OS or project grid for records and BIM.
Reports are issued promptly after each monitoring cycle so design and site teams can interpret movement quickly and make informed decisions.

Frequently Asked Questions
A baseline is the initial set of readings taken from all monitoring points before any works begin. Every subsequent visit measures movement relative to this baseline, so it is essential that it is established accurately and in a stable, undisturbed condition. Without a reliable baseline, it is impossible to distinguish real structural movement from measurement variation.
Trigger and alarm levels are pre-agreed movement thresholds that define when action is required. A trigger level typically prompts increased monitoring frequency or a review by the structural engineer; an alarm level indicates that works should pause while the situation is assessed. These thresholds are normally set by the structural or geotechnical engineer and agreed with the project team before monitoring begins — we incorporate them into every report so status is clear at a glance.
If a reading exceeds a pre-agreed threshold, we notify the project team immediately — we do not wait for the next scheduled report. The alert includes the affected monitoring points, the magnitude of movement and a comparison against all previous cycles, giving the structural engineer the information needed to make a prompt decision.
Monitoring frequency is agreed at the outset based on the type of works, structural sensitivity and project risk. Typical programmes run weekly or fortnightly during active construction, stepping down to monthly as works complete. Frequency can be increased at any point if movement trends or site conditions require it.
Yes — our monitoring reports are produced to a standard suitable for use as evidence in party wall proceedings. The data provides an objective, third-party record of structural behaviour throughout the works, which can be relied upon by party wall surveyors, engineers and, if necessary, in dispute resolution. Reports include clear references, dated readings and a full movement history for every monitored point.
Using Leica total stations with survey-grade reflective targets and a stable control network, we routinely achieve measurement precision in the order of 1–2 mm in 3D. Readings are taken using consistent instrument setups and procedures on every visit, so that changes between cycles reflect genuine structural movement rather than variation in method.
