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.
