BUILDING & ADJACENT ASSET MONITORING
Building Geotechnical Monitoring Singapore
Track building settlement, tilt, cracks and vibration during nearby excavation, tunnelling and redevelopment, with traceable baselines and engineering review.
INTRODUCTION
Monitoring Buildings During Adjacent Works
Building monitoring addresses how a structure responds to excavation, tunnelling, vibration and changing ground conditions. A responsible programme records pre-existing condition, separates normal environmental response from construction effects and provides information the appointed engineer can act upon.
PROJECT RISKS
What Monitoring Must Resolve
Measurement programmes need to answer the real construction and asset questions, not simply produce instrument readings.
Pre-existing movement and cracks
A visible crack is not necessarily new. Condition surveys, datum checks and credible baseline readings are essential.
Different structural systems
Shophouses, high-rise buildings, industrial structures and houses may need different monitoring points and review criteria.
Access and disturbance
Occupants, fragile finishes and site interfaces affect sensor placement, protection, frequency and documentation.
ENGINEERING APPLICATIONS
Where the Monitoring Matters
Monitoring scopes are selected from the mechanism of ground or structural change and the consequences for the assets concerned.
Settlement and angular distortion
Precise levelling or survey prisms on representative structural elements to reveal differential movement.
Crack width and tilt
Crack gauges, displacement transducers and tiltmeters on selected locations, with temperature context.
Vibration-sensitive occupancy
Vibration monitoring where appropriate for construction activities and sensitive buildings or equipment.
Neighbouring excavation or tunnelling
Instrument sets selected against predicted deformation, groundwater effects and programme stages.
INSTRUMENT SELECTION
Typical Instruments and Parameters
Illustrative options only. Instrument location, quantities, frequency and action levels require project-specific engineering assessment.
| Engineering situation | Parameters / methods | Practical monitoring consideration |
|---|---|---|
| Differential settlement | Levelling points / ATS | Control stability and pattern across elevation |
| Crack behaviour | Manual gauge / electronic crackmeter | Crack orientation, temperature and pre-existing width |
| Building rotation | Tiltmeter / survey | Sensor orientation and influence of daily cycles |
| Construction vibration | Vibration monitor | Work method, time history and selected criteria |
PROJECT DELIVERY
From Project Scope to Useful Engineering Evidence
GEOUE works with contractors, consultants and project owners to clarify technical responsibilities and establish practicable workflows.
Baseline condition
Record cracks, finishes, structure type, reference marks and instrument installation details.
Monitoring arrangement
Specify measurement points and instruments based on expected deformation mechanism.
Quality and event log
Check accuracy, reference stability, survey method and construction activity correlations.
Professional response
Transmit verified movement trends and anomalies to the appointed competent engineer.
ENGINEERING PERSPECTIVE
Separate building monitoring from compliance inspections
The details below are project-design considerations; final requirements are determined from each site and approved specification.
Construction impact monitoring
Typically tracks movement during adjacent works to assist project engineering decisions. It does not determine overall building safety in isolation.
Periodic structural inspection
BCA’s PSI regime uses appointed qualified structural engineers; project monitoring data can be a useful record but is not a substitute for the mandated inspection.
Heritage and shared walls
Old masonry, timber and party-wall systems may require more careful baseline documentation and limits on invasive installation methods.

Building monitoring is not the same as BCA’s statutory Periodic Structural Inspection or Periodic Facade Inspection. Those inspections must follow the appropriate regulatory regime and qualified-person requirements.
