An automated total station system for the Northern Line extension

Bruno Norberto , Head of Geomatics, Geotechnical Observations

The NLE is the first major tube extension on the London Underground network since the Jubilee Line Extension. The scheme consists of two 5.2m internal diameter, 3.2km long tunnels starting at Battersea Power Station, passing through Nine Elms Station and onto two shafts at Kennington. Two SCL tunnels used to advance the TBM tunnels to a section of the Northern Line called the Kennington Loop, connecting to the existing tunnel through two step plate junctions (SPJ).  A network of automatic total stations (ATS) was used to monitor buildings above the SPJs 24/7, supported by manual readings from BRE sockets and barcodes.  Several logistical and technical challenges were encountered during the ATS system planning, setup and operation and were overcome without compromising the quality of the data or the client’s needs.

Bruno Norberto’s professional experience was built working almost exclusively in the Instrumentation and Monitoring (I&M) sector. He is widely experienced in the design, installation, monitoring and reporting of many forms of geotechnical and structural instrumentation. Bruno completed a degree in Topographic Engineering in 2001 and joined Tecnasol, a renown geotechnical company in Portugal. In 2013, he moved to TÜV SÜD Bureau de Projetos, the leading I&M company in Brazil, working on projects related to the Olympics in the Rio de Janeiro region. In 2016, Bruno joined Geotechnical Observations as the Head of Geomatics and is also currently employed on the Northern Line Extension as the Assistant Project Manager. Bruno has worked on major geotechnical and structural monitoring schemes both in the UK and abroad, on tunnelling projects, rail infrastructure and road infrastructure as well as slope stabilization, compensation grouting and several construction projects.

Imaging total stations – static and dynamic monitoring without prisms

John Brewster, Managing Director, Imetrum Ltd

What if you could use a robotic total station (RTS) for monitoring, without prisms? Imagine the savings in set-up time and access costs. What if this device could also give you multipoint monitoring data at 100Hz? With the integration of cameras into many high end Total Stations (Trimble SX10, Leica Nova…) and advances in image processing, this is not so far-fetched. Surveyors are already using images for improved reporting, identifying targets during DR measurements, and for measurement (photogrammetry). Trimble’s Vision whitepaper identifies a bright future ahead, as does European research. Paul Waterfall will discuss the current state of the art for monitoring using an image assisted RTS, and the potential impact on prism and laser-based tracking.

Over the last 10 years John Brewster has taken Imetrum from an embryonic start up to a mature global business that has a presence in many of the leading high technology companies around the world. Imetrum® is a globally recognised leader in the field of non-contact video measurement systems. Its patented sub-pixel pattern recognition technology, Video GaugeTM delivers fast, ultra-high resolution measurement of displacement, rotation, strain and extension on any material or structure. John created the early relationships with several of our key distributors and has more recently been a major contributor to our prototype for a new structural monitoring technology (VG360).

Automated monitoring in the digital era

Marco Di Mauro, Segment Manager, Leica Geosystems

Automated monitoring solutions have been driven not only by advancements in measuring technology but also by the availability of new telecomms or computing solutions. Thanks to the power of modern hardware and new software algorithms, automated scanning processing and real-time surface comparison are now possible, opening the door to monitor in real time any structure virtually without the need of prisms. High-resolution imaging is now possible thanks to faster telecomms infrastructures saving time and money for site inspections and visual checking, which can now be done remotely in the field via wireless mesh and computed in the cloud.

Marco Di Mauro is a monitoring expert and passionate since more than 15 years. Segment Manager for Leica Geosystems in UK with proven experience in designing and delivering monitoring solutions in several countries using optical, geotechnical, dynamic and environmental sensor for a total of over 150 projects in Europe, Middle East and Asia including CrossRail (UK), TAV (Italy), Dniepr 4 major dams (UA), Metro Doha and Son Lah big landslide (Vietnam).

Automatic 3D monitoring and the use of network adjustment on the railway

Dominic Kisz, Head of Operations , Datum Monitoring

Since its introduction, automatic 3D monitoring has developed into an extremely fluid and practical solution to better understand risks and impacts to railway infrastructure. This talk discusses the key developments and hurdles that the method has faced over the years whilst also considering the importance of adjustment packages in the search for more accurate data. Examples from projects will demonstrate the improvements in efficiency and reliability of modern monitoring solutions compared with the past. Solutions are continuously improving, sometimes faster than project specifications, the presentation aims to stimulate debate on the state of the art in the monitoring industry.

Dominic Kisz is a graduate from Birmingham University in Geology who then studied an MSc in Hydrogeology at the same university. He began work as an environmental consultant for WSP before starting his monitoring career as a project engineer on C300 Crossrail. He then moved to Datum where he has been working as the Operations Manager for the last year. He looks after the delivery of all southern survey, structural monitoring and geotechnical works.

The 4th industrial revolution, where monitoring data meet BIM

Marco Di Mauro, Segment Manager, Leica Geosystems

Modern monitoring systems are good examples of the ‘Internet of Things’ where sensors are smart and able to communicate with each other and share results over the web to present computed and filtered data as information for decision makers. This optimisation of risk management is part of the proven effectiveness of adopting BIM, a solution with the aim of reducing the risks of delivering a project not being on time or on budget through implementing a more connected data strategy. This presentation will show where monitoring data can fit into the BIM process through possible and future integration.

Addressing the supply chain: the true ROI of UAV survey services

William Tompkinson, Principal, Insightful Dimensions

Reasons for utilising UAV surveys are discussed in terms of speed, accuracy and sensor choice. However, this can be a very short-term and insular view to whether UAV surveys are bringing benefit to customers. There is typically little discussion of the implications on supply chains. Drawing upon experiences of Canadian UAV survey company, Sumac Geomatics, in undertaking monthly volumetric monitoring contracts, this presentation will expand the scope of how we assess the impact of these activities. It will illustrate how when monitoring stockpiles, there can be technical decisions made by the UAV provider that will directly influence supply logistics and just-in-time strategies.

Surveying in Antarctica – blue ice runways for large Jets

Ian Stilgoe, Vice President Geopositioning Europe, Topcon

The utilisation of Blue Ice in Antarctica for landing aircraft is not a new concept. But with glaciers on the move and changing sea ice conditions it brings new demands and challenges for servicing scientific bases and visitors in this remote continent. The extreme climate makes for special requirements when undertaking surveying and research to determine the potential suitability of a site for use as a “certified runway”.

Desktop studies by Antarctic Expeditions and Logistics had identified potential sites from satellite imagery and radar data and an area of interest was defined for closer inspection and surveying as a potential new runway for large jet aircraft.
