Structural Building Monitoring Surveys London, Brighton, Sussex, Surrey and surrounding areas
Movement monitoring on a building or structure.
Type 1 (Standard Monitor).
A number of retro targets will be strategically glued/positioned to the building/structure faces. Precise monitoring will take place with a number of closed loop traverses and measurements to the targets in order to provide a mean set of coordinated results which will be used as a base and comparison for further visits.
Returning to site at requested intervals to re-survey the targets and produce reports on any movement in the building.
These will be shown by positive/negative values in a spreadsheet format. An example can be seen below.
The photo above shows the retro targets fixed to the building face, this is where the monitoring surveyors take various survey measurements to be able to create the monitoring report to show any movement on the building.
Type 2 (Precision Monitoring).
This process is similar to Type 1 standard monitor but involves using a 'mini prism' type target which are fixed to the structure/building and use of a 00.1" survey instrument, this also includes re-traversing all monitoring control. A mini prism can be seen below. Please note that there is a cost implication with this method of survey.
What is a Structural Monitoring Survey?
A Structural Monitoring Survey is a specialized surveying technique that involves the continuous or periodic monitoring of structural elements, such as buildings, bridges, dams, towers, or any other infrastructure, to assess their behavior, stability, and integrity over time. The survey aims to identify and track any changes, movements, or deformations that may occur in the structure.
Structural monitoring surveys typically involve the use of various sensors, instruments, and data acquisition systems strategically placed on or within the structure being monitored. These sensors can measure parameters such as:
- Displacement: Measuring the movement or displacement of specific points or areas of the structure.
- Strain: Monitoring the stress and strain levels within structural components.
- Load: Monitoring the applied loads or forces on the structure, such as wind, vibration, or traffic loads.
- Vibration: Assessing the dynamic response and vibration characteristics of the structure.
- Crack Monitoring: Monitoring the development or widening of cracks in structural elements.
The collected data from the sensors is recorded and analyzed over time to identify any changes or anomalies that may indicate structural issues, deterioration, or movement beyond acceptable limits. This information can help engineers and stakeholders make informed decisions regarding maintenance, repair, or reinforcement strategies to ensure the safety and longevity of the structure.
Structural monitoring surveys are particularly valuable for critical infrastructure, high-rise buildings, historic structures, and areas prone to seismic activity. They provide real-time or periodic insights into the structural behavior and performance, allowing for early detection of potential problems and the implementation of timely corrective measures.
The surveying methods used in structural monitoring may vary depending on the specific requirements of the structure and the desired level of monitoring detail. These methods can include geodetic surveying, remote sensing, strain gauges, tiltmeters, accelerometers, and other specialized sensors and instruments.
