GEOTECHNICAL OBSERVATIONS LIMITED

What are inclinometers and how are they used? Inclinometers are used to measure displacements in ground and in structures that lie below ground level (e.g. retaining walls). To make inclinometer measurements a plastic (ABS) tube (the inclinometer casing) is installed in a borehole (for ground measurements) or a void former (for measurements inside a concrete structure) and the annulus between the ground or the concrete structure is filled with a cement/bentonite grout. At Geotechnical Observations we read each inclinometer casing twice with two independent inclinometer probes and we compare the results for each pair of readings to ensure that they lie within the random error associated with the survey. One probe is then used for all of the subsequent readings and the other probe is used as a back-up in case the routine probe is subsequently unavailable or if the subsequent readings with the routine probe require checking. All of our inclinometer measurements are examined for sources of systematic error such as bias, changes in alignment of the sensors and depth positioning. Adjustments are applied if required and noted. Our reports and presentations also include details of the ground profile and construction progress where appropriate.

Last week, two members of our team had the pleasure of attending a careers fair at one of our local secondary schools, where they spent a day talking to the pupils, trying to inspire them to consider a career in civil engineering. During the presentation our team showcased some of our most recognisable products, including the Measurand ShapeArray and the ElastiSense Sensor Technology sensors. Great conversations were had with some of the students, who were very keen to learn more about the opportunities that a career in civil engineering can offer. A big thank you to the students and staff for hosting us, we hope the day was enjoyable and informative. #civilengineering #careerinengineering #education #knowlegesharing

Talk to us about Remote Monitoring... Remote monitoring is where data is recorded locally on a datalogger, recovered using a telemetric connection and is normally presented on the internet. This form of monitoring is ideal for comparing the collected values, against thresholds that trigger alarms, which can be automatically issued as SMS or email messages. Our team can set up remote monitoring systems for most forms of structural and geotechnical instrumentation, with results presented in reports or on our online platform, Geodaisy®.

Flashback Friday Indeed! Heathrow Airport Terminal 5 was one of our early projects. As specialists in measuring soil suctions / negative pore water pressures, we were involved from a very early stage, measuring suctions in compacted samples to assess the material that would be used beneath the taxiway. When excavation commenced, we were there again to measure negative pore water pressures in the ground (due to the unloading) using our unique flushable piezometers. The results were consistent to those predicted by the analyses and helped improve confidence levels in this innovative construction process. 10 years later we were appointed as the monitoring consultant for the construction of Terminal 2B and we used the same approach and instruments to monitor the in situ negative pore water pressures in the London Clay cut slopes, as well as monitoring retaining walls and terminal buildings. If you want to know more about how to measure suctions and in situ negative pore water pressures visit our website www.geo-observations.com #piezometers #geotechnicalinstrumentation #geotechnicalmonitoring #geotechnicalengineering #geotechnicalmonitoringconsultant

FLASHBACK FRIDAY| M25, Godstone... In December 2000 a major landslide occurred to the north of the M25 at Godstone, just east of junction 6. The movement mobilised about 90,000 m3 of the slope and closed the hard shoulder. Geotechnical Observations has been monitoring the escarpment since November 2002. Since that time we have installed inclinometers and piezometers. We have also helped a number of the operators to understand the behaviour of the slope and implement a number of remedial solutions. Our work continues at this location and we are still making monthly visits to the site.

Monitoring Excellence at Hinkley Point C Hinkley Point C is a nuclear power station located in Somerset, England. It is currently one of the largest infrastructure projects in Europe and is expected to be the first nuclear power station to be built in the United Kingdom in over two decades. Geotechnical Observations has been involved in this project since its inception, with a dedicated team on site, providing a full suite of instrumentation and surveying services.

FLASHBACK FRIDAY | Elan Valley Aqueduct... Constructed between 1896 and 1906 the Elan Valley Aqueduct carried water from reservoirs in mid Wales to Frankley water storage works to the west of Birmingham. Leakage and a requirement for additional capacity requires the route to be updated with a series of by-passes. Geotechnical Observations is monitoring the existing structure, whilst cofferdams are installed to enable tunnelling to be undertaken. We are doing this using horizontal and circular SAAs to measure displacements, triaxial geophones to measure vibration and crack gauges.
