The benefits of automated monitoring to inform and control construction and built assets is examined in this state-of-the-art review. Robotic imaging systems, new telecoms infrastructures, software algorithms, GNSS, patch scanning, wireless mesh, the cloud and other technologies can all play a part in delivering real-time 3D monitoring. The session is includes real world projects in the tunnelling, road, rail and infrastructure sectors.

An automated total station system for the Northern Line extension
Bruno Norberto , Head of Geomatics, Geotechnical Observations
NLE is the first major extension on the London Underground network since the Jubilee Line in the 1990s. The scheme consists of two 5.2m internal diameter, 3.2km long tunnels starting at Battersea Power Station, passing through Nine Elms Station and on to two shafts at Kennington. Two sprayed concrete lining (SCL) tunnels advance the TBM tunnels to a section of the Northern Line called the Kennington Loop. The SCL tunnels connect to the existing tunnel through two step plate junctions (SPJ) with new stations at Battersea Power Station and Nine Elms.
Geotechnical and structural monitoring have been deployed.. The presentation will focus on 24/7 automatic monitoring using automatic total stations supported by manual readings from BRE sockets and barcodes used to monitor buildings.
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 Novaâ€¦) 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.

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). Skilled in Monitoring, Telecommunications, Power supply systems, Strong operations professional with a BS focused in Telecommunications from Politecnico di Milano Marco is also expert in Big Data and IoT technologies.

Automated patch scanning and data integration drive better monitoring solutions
Matthias Gropp, Head of Monitoring, Murphy Surveys
Murphy Surveys Monitoring Department provides sensor equipment and manual monitoring services.Using examples from actual and past projects we will show our multi-technology approach to monitoring design, where sensor integration allows faster and more accurate data interpretation and increases the overall solution resilience and reliability.While modern software platforms allow results comparison, Murphy Surveys is working to bring the integration to a deeper level where the data are integrated from the computation stage to produce better results including GNSS data trends to improve Robotic total station networks where stable points are not available.
Matthias Gropp, Head of Monitoring, Murphy Surveys. Studied Surveying/Geomatics at University of Applied Science in Dresden, Germany. Worked as Surveyor and then Survey Manager in Berlin at a large survey company during the boom years 1996/2006 on projects like the Berlin Hauptbahnhof and Potsdamer Platz. Relocated to Ireland in 2006 to work with Murphy Surveys on Luas Line Extension, Limerick Tunnel, Grand Canal Theatre, National Maternity Hospital, Dublin M1, Corrib Gas, Intel Leixlip Upgrade.
Carrier developed from Senior Surveyor to Technical Manager, Operations Manager, Special Projects Manager, then Monitoring Manager. Change over to Murphy Surveys UK in spring 2015 after commuting for 3 years for Murphy Surveys monitoring on Crossrail C430 and C410. Now Head of Monitoring, building up the Monitoring Department to one of the main monitoring competitors in the UK. Murphy Surveys monitoring teams currently work on around 70 monitoring projects in London and across UK and Ireland.

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.
