In August of 2018, SIS Ltd were commissioned by Tasiker Industrial, on behalf of Hertfordshire County Council, to undertake Remote Structural Vibration Monitoring along with Pre & Post conditional surveys of 5No. Private dwellings.

Our clients were installing a new sheet pile wall in close proximity of the dwellings and wished to obtain clear and precise vibrations level data with alarm monitors and beacons pre, during and post the installation.

SIS Ltd surveyors inspected all external and internal elements of all 5No. Properties and presented all data obtained, including photographic evidence, in clear and comprehensive reports.

For a short period prior to the installation works commencing, remote monitors, along with level alarms and beacons, were installed at all property locations in order to obtain base level readings. Monitors were left in place for the duration of the works with weekly reports submitted to the clients on levels obtained, including Velocity Acceleration (mm/s) and Frequency (Hz) of vibrations.

Following the completion of the installation, SIS surveyors returned to undertake a post conditional survey of all 5No. dwellings, recording any change to both external and internal elements. This data was again provided in clear comparison reports with photographic evidence.
