Geotechnical Observations (GeO) has been delivering structural and geotechnical monitoring solutions for more than 10 years. The company has worked on many high profile construction projects such as Heathrow Terminals 2 & 5 and the new Wembley Stadium. GeO can offer geotechnical knowledge and instrumentation know-how, which combine to enhance our client’s understanding of the projects being monitored.

Geotechnical Observations is the Exclusive Distributor of ShapeAccelArray (SAA) in the UK and Ireland.


SAA are manufactured by Measurand Inc of Fredericton, Canada.

We also sell SAA on behalf of Measurand in Qatar and United Arab Emirates.

ShapeAccelArray (SAA) is a displacement and vibration monitoring system and it arguably the most exciting recent development in instrumentation and monitoring. An SAA is a string of rigid segments separated by joints that can move in any direction but cannot twist. MEMS gravity sensors measure tilt in two directions. Processors transform the position (e.g. X,Y & Z) of each sensor to produce shape and change of shape. Each SAA comes wrapped around a drum and is then placed into a small (27mm ID) uPVC tube. There is no joining of individual sensors to be done in the field, which makes the installation of Shape Arrays exceptionally quick. Displacements can be recorded onto a datalogger, directly onto a computer using a USB interface or onto an Android mobile phone using an SAA Field Power Unit. Vibration data can calso be gathered using a computer.
