We are pleased to announce that Jonathan Gammon has joined Geotechnical Observations as a Non-Executive Director. Jonathan is a Chartered Civil Engineer and a Chartered Geologist with over 40 years of experience on a wide range of UK and international projects such as Crossrail, HS2, West Rail in Hong Kong and the Dublin Metro North project. He has a very strong background in Instrumentation and Monitoring, and has been involved in the specification and procurement of I&M throughout his career.
Until recently Jonathan was Technical Director for Tunnels and Geotechnics at the global consultancy CH2M, so we are very excited that he will be joining us and look forward to receiving the benefit of his experience.
Geotechnical Observations is pleased to be sponsoring the drinks after the joint BGA / BTS meeting at the ICE on 22nd October.
We are very pleased to announce that GeO's Northern Line Extension team has been shortlisted for an NCE Tunnelling Award in the Community Engagement category. This is for the work done in the Kennington area of south London, where they installed, read and decommissioned over 300 survey points to protect 73 properties. Access was negotiated with 123 different people and required dedication and professionalism. Well done team!!
We are pleased to announce that we will be sponsoring the Chalk 2018 conference. The conference is being organised by the British Geotechnical Association (BGA) and will be held at Imperial College London (IC) on 17th and 18th of September 2018. Geotechnical Observations has a very long relationship with BGA and IC, so we are proud to be associated with this prestigious event. We are sponsoring students at the event and will be putting up our exhibition stand.
Our Head of Geomatics, Bruno Norberto, will be giving a presentation at GEO Business on 23rd May, about the networked system of total stations that we installed for the Northern Line Extension Project in London.
Pictured are rods for settlement plates, ready for shipping from our warehouse. They will be installed this week on a new project to monitor settlements during surcharging.

A new standard has been published on inclinometer measurements. This is the third in a series of standards that are the work of the ISO TC182 WG2 committee. The first two standards were on General Rules and Extensometers. The Working Group is currently drafting new standards on piezometers and total pressure cells. You can purchase the inclinometer standard from BSI at the following URL:
Mohamed (Instrumentation Engineer at GeO) being trained in how to calibrate an inclinometer probe using our UKAS certified rotary table.
All of our inclinometer probes are examined and cleaned after every site visit. They are put through a static tube test every week, to track the check-sums under repeatable conditions. This identifies any changes, such as worn bearings, at an early stage. They are checked using our rotary table every three months and a new calibration certificate is issued if any adjustments are done. A full calibration is carried out every 12 months.
We believe this process helps us deliver high quality inclinometer measurements in piles, retaining walls and slopes. Contact us if you want to hear more about how we do this.
SAAV is the newest and most advanced ShapeArray model.
Inspired by direct feedback from customers, SAAV uses a new, unique, off-the-reel cyclical installation system, which inserts the ShapeArray in a zigzag pattern into casings from 47 mm to 100 mm in diameter. The SAAV is then locked into place with a Spring Box assembly.
SAAV is ideal for using in existing conventional inclinometer casings or for new installations into smooth casings such as reservation tubes in piles and diaphragm walls.
SAAV is available with 500 mm long segments and in total lengths of up to 150 metres.
