When a structure is identified as being at risk from subsidence, it is important that a framework is promptly put in place to begin monitoring the direction & magnitude of movement. Monitoring can be preventative or investigative and examples of use include insurance risk assessment; pursuit of a claim; or as a dataset to inform expert advice.
An initial survey will provide a baseline and then monitoring will be carried out at predetermined intervals. By quantifying any significant movement, a monitoring survey will help the client assist with the planning of preventative or remedial work.
Examples of monitoring surveys that we have undertaken include property subsidence; above ground pipe sinkage; retaining wall movement & bulging; pile & foundation level monitoring.
An assessment of requirement usually incorporates an on-site meeting with the client further to which suitable methods & timescales will be proposed & agreed. At each monitoring interval a report can be compiled to the client requirement incorporating a summary of the survey data presented in an appropriate format.
