What a  Deformation and Settlement Monitoring Survey Covers

Deformation  monitoring is the practice of measuring a structure, slope, or asset over  time with the same survey methodology, comparing successive measurements to  detect movement, settlement, tilt, or shift. The deliverable is typically a  series of survey reports showing each monitoring period's results, the  difference from baseline, and the rate of movement. Monitoring is used during  construction (adjacent excavation impact, dewatering effects), as part of  geotechnical risk management (active landslides, retaining walls), for  structural health (historic buildings, distressed structures), and for  compliance with permit conditions. We perform monitoring with the same field  crews and instruments that perform our other survey work, providing  consistent results across long monitoring campaigns.

Common  Reasons Clients Request a Deformation and Settlement Monitoring Survey

•  Construction monitoring of adjacent buildings during excavation, shoring, or  dewatering

• Active landslide or slope monitoring

• Retaining wall monitoring after construction or during  distress investigations

• Historic or distressed structure monitoring

• Bridge or tunnel monitoring during adjacent construction

• Permit condition compliance requiring monitoring reports to  the agency

• Pre- and post-construction documentation to establish  liability baselines

• Subsidence monitoring (oil/gas extraction, groundwater  pumping, settlement)

• Lawsuit or insurance documentation of structural movement

What’s  Included in a Deformation and Settlement Monitoring Survey

• Monitoring  plan development including monitoring points, frequency, accuracy targets,  and reporting

• Establishment of stable reference benchmarks outside the  influence area

• Installation of monitoring targets or prisms on the  structure or asset

• Baseline survey establishing initial position of all  monitoring points

• Periodic monitoring surveys at the agreed frequency (weekly,  monthly, quarterly, event-triggered)

• Comparison reports documenting movement at each monitoring  period

• Trend analysis and threshold notifications

• Stamped monitoring reports for agency or permit submittal

Common  Deformation and Settlement Monitoring Survey Add-Ons

• Crack  monitoring on building walls (crack gauges and width measurement)

• Tiltmeter integration for high-frequency angular monitoring

• Photographic documentation of monitored conditions over time

• GPS-based monitoring for long-term slope or landslide  tracking

• Specific threshold alerts triggering immediate notification

What We  Need to Start Your Deformation and Settlement Monitoring Survey

• Project  address and the asset being monitored

• Reason for monitoring (construction, geotechnical,  structural, compliance)

• Monitoring frequency required (one-time, weekly, monthly,  event-driven)

• Accuracy and threshold targets (any specific movement that  requires notification)

• Reporting format and audience (engineer, agency, attorney,  insurer)

• Duration of the monitoring campaign

• Site access details and any safety considerations

• Any existing baseline survey or monitoring data

Our  Deformation and Settlement Monitoring Survey Process

1. Monitoring  plan. We develop the plan with monitoring locations, frequency, accuracy, and  reporting in coordination with your engineer or geotechnical consultant.

2. Reference benchmarks. We establish stable reference points  outside the influence area.

3. Baseline survey. We install monitoring targets and survey  them to establish the baseline.

4. Periodic surveys. We return at the agreed frequency and  re-survey all monitoring points using consistent methodology.

5. Comparison and reporting. We compare each period to  baseline (and prior periods), document movement, and issue the report.

6. Threshold notifications. If movement exceeds defined  thresholds, we notify per the agreed protocol.

Deformation  and Settlement Monitoring Survey Deliverables

• Monitoring  plan document

• Baseline survey report

• Periodic monitoring reports comparing each period to  baseline

• Movement trend graphs and tables
