Solutions for Monitoring - Man-Made Structures
Leica Geosystems' surveying solutions are used worldwide for the monitoring of man-made structures such as bridges, dams and buildings, during construction as well as after.
Safety on the High Seas
Government awareness of the need for increased safety on offshore works is increasing worldwide. Russia has a strong interest in offshore safety and is in the process of preparing a bill concerning “protecting the seas of the Russian Federation against oil pollution”. There are currently two oil-drilling rigs in operation, both belonging to “Lukoil” Ltd. The bill is not yet ready or obligatory, but Lukoil’s directors have already initiated geodynamic monitoring systems on a maritime, ice-resistant platform over the Yuri Korchagin oil deposit to ensure safe operation and to protect workers from unexpected occurrences on the high seas. more
The Shard: London's New Skyline
Byrne Bros is both one of the UK’s and the world’s leading formwork construction companies. They were appointed by main building contractor Mace to carry out the concrete substructure and superstructure works for Europe’s tallest building – The Shard in London – in a contract worth more than 64 Mio. Euro (78.5 Mio. US Dollar). In the summer of 2009, Leica Geosystems was approached by Byrne Bros to develop a real-time slip-form rig positioning system, used to construct the central concrete core of The Shard. more
Cochem Tunnel: A Tight Fit
Trains have been running through the Kaiser-Wilhelm Tunnel under the center of the historic town of Cochem on the Mosel in Germany for 130 years. Renovations are now being carried out on this tunnel, while at the same time work is in progress on a second tunnel. The new tunnel is 4,242 m (2.64 mi) long and scheduled to open to rail traffic in 2016. The 200 Mio. Euro (261 Mio. US Dollar) tunnel construction project is part of the Deutsche Bahn plan to extend the Coblenz/Trier line and bring its infrastructure up to current safety standards. Due to critical geological conditions, an automatic monitoring system was developed to transmit measurement data to the shield driver on the tunnel boring machine in real time. more
Yesterday’s Negligence Becomes Today’s Problem
The level of pollution at the Schnepfenmatt site in Zuchwil makes it one of most contaminated pieces of ground in the Swiss canton of Solothurn. Although the pollution threatens two of Solothurn’s public drinking water sources, it has not been possible to successfully remediate the land until now. Emch+Berger is working on the remediation of this contaminated waste site. more
Structural Monitoring of Michigan’s Highway Bridges
The State of Michigan (USA) is surrounded by the largest source of fresh water in the world, the Great Lakes. Lakes Superior, Michigan, Huron, Ontario, and Erie play tremendous environmental and economic roles, and are of vital importance to Michigan and the United States in terms of shipping, fishing, tourisim, and a clean water source. Between the Great Lakes, their associated watershed, and the State’s extensive highway system, there are also a significant number of highway bridges that require service, maintenance, and reconstruction in order to ensure and maintain safety to the motoring public. more

Arbizelay´s bridge, 380 meters long, 6 spans high, 5 pylons and 12 meters wide is part of the AP-1 Vitoria - San Sebastián Motorway and is located near the city of Mondragon. Thanks to Leica GNSS technology, it was possible to successfully complete the manoeuvre of incremental launching of the bridge´s deck over the pylons with an error of less than 3 centimetres. more
GNSS Guide System for Pile Embedding Port of Cádiz, Spain
The new Bridge in the Bay of Cadiz, known as "Puente de la Pepa" (1812 Spanish Constitution), was the highest bridge in Europe in 2010. Its 3.1 km length, 180 metres height and 540 metres span makes it a true surveying challenge. more
Railway Bridge Monitoring Kirchtobel, Switzerland
The extension of the railway line between St. Gallen – Arth- Goldau is part of the integration of Eastern Switzerland with the New Railway Link through the Alps (NRLA). There are several engineering projects associcated with this enlargment, such as the building of the new railway bridge close to St. Gallen. As the new bridge will be built close to the existing one hundred year old brigde, the project is complex as the old bridge is made of natural stone and the foundation of its pillars are not accurately defined. This means that construction work can affect the old bridge in the forms of settlement and torsion. A permanent monitoring system is required to monitor these movements and inform the key people in the railway service "SOB Südostbahn" in any case of emergency. more
Monitoring a dam wall in a Polish Copper Ore Enrichment Facility, Poland
In December 2008 the first monitoring project in Poland for the KGHM Polska Miedz SA (Polish Copper) Company was started. Located in western Poland, KGHM Polska Mied SA (Polish Copper) is the largest company in the region, employing approximately 18000 people. At present it is the 10th largest copper producer in the world. more
Monitoring of Excavation Slopes in an Open Pit Mine
The Bełchatów is a large brown coal mine in the centre of Poland, 150 km west of the capital, Warsaw. Bełchatów quarries brown coal in open pit mining with a surface of over 30 sq. km. The operator is the Polish Energy Group – Open Pit Mine Bełchatów. Due to the increasing demands for mine efficiency and slope stability in the excavation area, the customer decided in 2006 to implement an automatic monitoring system combined with a mining control system. more
Monitoring Along the Construction Site of the Warsaw Metro Line 2
The Warsaw Metro (Metro warszawskie) is a rapid transit system serving the city of Warsaw, the capital of Poland. Currently it consists of a single north-south line (Line 1) that links central Warsaw with its northern and southern suburbs. The first section was opened in 1995 and then gradually extended until it reached its full planned length in October 2008. The construction for building the initial section of the second, east-west line (Line 2) started in August 2010, with completion planned for late 2013. This section will be 6.1 km long (including a tunnel under the Vistula River) and has 7 stations, one of these a transfer station shared with Line 1. The transfer station Swiętokrzyska’ also connects the center of the city via its Central Railway Station (Warszawa Centralna) with the National Stadium for the Euro 2012 championships. Then, at the second junction (Stadium station) the line divides in two parts, one running toward the North-East (Bródno) and the other toward the South-East city region (Gocław). The completion and operation of Line 2 is planned for 2015. more
Monitoring Bridge Structures Under Static Loads
The Maria Skłodowska-Curie Bridge (Polish: Most Marii Skłodowskiej-Curie, formerly North Bridge) is a road bridge over the Vistula River in Warsaw, Poland. The road bridge in the capital of Poland links the northern suburbs of Białołęka and Bielany and opened on 24 March 2012. The total length of the bridge is 795 m (the main river span is 160 m). The applied precise Nivel220 inclinometers network makes it possible to measure the deflections of a bridge construction under static loads without the necessity of using external reference points. The project has been implemented in cooperation of the Road and Bridges Research Institute in Warsaw, Leica SU Poland and O.N.T Krakow. more
Monitoring System for Hong Kong Airport Express Line
The Kowloon Southern Link (KSL) will be a 3.8 km connection between the East and West Rail in Hong Kong. The construction of the $8.3 billion KSL is scheduled for completion in 2009. The Kowloon-Canton Railway Corporation (KCRC) in Hong Kong acquired an Automation Deformation Monitoring System from Leica Geosystems in December 2005 for continuously monitoring settlement and overall deformation of a section of existing Airport Express Railway. more
Monitoring Rail Tracks during Construction of Noise Barriers, Hong Kong
As one of the busiest and most crowded rapid transit system in the world, MTR (Mass Transit Railway, Hong Kong) operates high frequency train services from early morning until midnight. Due to the noise of the trains, areas where trains operate outdoors, like Tai Wai, suffer significantly from noise pollution. Serving as the busest interchange station in New Territories, connecting Ma On Shan Line to East Rail Line, Tai Wai Station and Depot are also one of the busiest hubs for train operation. As resdents move into the newly built residential buildings above Tai Wai Depot, the noise pollution problem is expected to affect an increased number of people. more
Monitoring System at Tsuen Wan West Station, MTR West Rail Line
The TW7 area in Tsuen Wan West Station Hong Kong, is the planned location for the development of a new urban infrastructure. Since the construction is very close to an existing MTR (Mass Transit Railway, the rapid transit railway system in Hong Kong) tunnel and station, an automatic deformation monitoring system (ADMS) must be installed for security, because any deformation to the MTR could threaten the lives of thousands of passengers. more
Monitoring of the Central-Wanchai Bypass During Construction
The Island Eastern Corridor is a major expressway connecting Causeway Bay to Chai Wan, which was completed in the 1980’s. In February 2011, a bridge abutment supporting the slip road was found to have unusual structural movements, causing the temporary suspension of underground works and soil stabilization and measurements to be taken immediately. As further settlement is still possible and construction work needs to continue, which could potentially threaten the safety of road users, further monitoring of the bridge structure is required to provide real time deformation information to the engineers, so that they can make a correct decision to ensure the highest degree of safety. The automated deformation monitoring system (ADMS) was initially set up temporarily to automatically operate round the clock, providing precise deformation measurements. However, in March 2011, the system was turned into a permanent system. more
Slope Monitoring at Adaro Tutupan Coal Mine, Indonesia
Tutupan mine is one of the largest open cut coal mines in Indonesia, situated in the South Kalimantan province 300 km from Banjarmasin. The mine has a total coal production of over 40 million tons per annum. The Tutupan’s pit dimensions are approximately 16,000 x 2,500 x 250 m. more
Concrete Dam Monitoring in Montereale Valcellina, Italy
The Ravedis dam is located in the municipality of Montereale Valcellina (PN), in the area where the Cellina torrent, (tributary of the Livenza river) runs from the mountain section to the valley section, spreading out over the Friulian plain in the province of Pordenone. It is a mass gravity concrete dam, measuring 68 m high with a reservoir storage volume of 22.6 million m3. The primary function of the basin is to detain the overflow from the Livenza river, its secondary uses are irrigation and hydroelectricity. more
Chemical Plant Monitoring
The plant is located in the center of Italy and is a chemical plant for the production of high explosive chemical liquids. Maintenance work inside the plant by a construction company making some consolidation works (like micropiles, etc.) is required. To avoid any effect and to maintain the plant’s activity, the customer is obliged to monitor the pipes during all the construction operations. Any unforeseen deformation of the pipes causes a total stop of the prodution, which costs approximately 1.000.000 EUR per hour. more
Rail Tunnel Monitoring in Sochi, Russia
A railway tunnel near Sochi in the Russian Krasnodar region is being monitored as part of the construction preparations for the 2014 Winter Olympic Games. The tunnel is part of the only rail line for all passenger traffic to the Sochi resort area from central parts of Russia and for cargo traffic supplying construction sites in Sochi. Due to the planned construction of two road tunnels above the railways, the decision was made in 2011 to set up an automatic monitoring system for the existing tunnel. more
Heavy Loads on Weak Foundations
The newly opened D-Runway at Tokyo International Airport Haneda was a complex structure to build, as it is located on reclaimed land. Heavy airplanes weighing hundreds of tons each, take off and land on the newly constructed runway daily. Continuous monitoring is important for safe operation, as large movements can influence the safety of the runway. more
Controlling The Bow
The Bow, with construction costs at an estimated 1.5 billion Canadian dollars, is the largest office space in Calgary and the tallest building in Canada outside of Toronto. During the construction of a skyscraper as complex as the Bow, the structure will temporarily lose its exact verticality and the building will tilt, contract, and expand. To ensure the functionality of such a complex and innovative design, MMM Geomatics, Ledcor Construction, and steel fabricators/erectors Supreme Walters Joint Venture, established an innovative “neutral” building control network that combined leading-edge technologies, advances in geomatics methodology, and rigorous quality control and quality assurance procedures to deliver precise real-time data. more
Monitoring Europe’s Tallest Building
Renzo Piano, the architect for The Shard, considers the slender, spire like tower a positive addition to the London skyline. The sophisticated use of glazing with expressive facades of angled panes is intended to reflect light and the changing patterns of the sky, so that the form of the building will change according to the weather and seasons. The Shard London Bridge will tower 306m (1,017 feet) into the sky and will be the tallest building in the European Union and the tallest building in the United Kingdom. When completed in 2012 it will soar more than 70 floors above London. more
Swiss Bridge, Visible World-wide
A bridge over the Rhine near the village of Diepoldsau, not far from the headquarters of Leica Geosystems AG, is one of the most thoroughly monitored bridges in the whole of Switzerland. However, it is not about to collapse at any moment. The reason for this is the cantonal highways department gave Leica Geosystems permission to install any number of sensors and convert the cable-stayed bridge into a “test structure”. The canton benefits from this arrangement, as do (potential) customers, university students and last but not least, the Leica Geosystems product specialists. more
Monitoring Toronto’s Union Station
Downtown Toronto’s Union Station is Canada’s busiest rail terminal, handling about 65 million passengers annually. Built from 1915 to 1920, it’s considered to be a masterpiece of Beaux Arts architecture, expressed in the ornately colonnaded front and the 76 x 27 m (250 x 90 ft) Grand Hall, which is famous for its marble floor, soaring arched roof, and four-story windows at each end. more
Accurate GNSS Everywhere with SmartNet
Ten years ago, RTK surveys typically involved two GPS receivers (a base and a rover), a lot of batteries and cables, two radios, a tripod, a pole, and a backpack to carry it all. Today users can choose between a GPS or a GNSS receiver, and a radio or a mobile phone, and it all fits on the pole. With the establishment of RTK networks, they can also choose to work with an RTK rover within these networks instead of setting up their own base-station. Leica Geosystems SmartNet gives users easy access to precise Network RTK data, where they experience the best availability, reliability, and traceability using internationally recognized standards, combined with flexible and affordable subscription options that meet the needs of the local market. more
A New Network for a Town Torn in Two
The town of Staufen in the Black Forest has literally been torn apart: following failed geothermal borehole drilling, the ground on which the town and its 7,800 inhabitants stand has risen by up to 40 cm (15.7 in) in the last three years. This has had serious consequences for some of the houses in this historically listed town, some of which have cracks running through them that are up to 10 cm (3.9 in) wide. The town council commissioned surveying engineers Weber to set up a geodetic deformation network to monitor the continuing rise of ground levels. more
Automated Deformation Monitoring Apollo Bridge, Bratislava, Slovakia
The Apollo Bridge is one of five road bridges across the Danube in Bratislava, connecting the centre of the city with the district Petržalka. The traffic load and temperature changes cause deformation of the bridge structure. In addition, the use of the developed automated measurement system (AMS) for long term monitoring allows the Department of Surveying of the STU Bratislava to determine actual information about the deformation of the main structure in real time. more
Slope Stability Monitoring Brown Coal Excavation, Czech Republic
Severočeské doly a.s. is the largest producer of brown coal in the Czech Republic. The company was established by the Czech National Property Fund in 1994 by merging two major brown coal producers - the Bílina Mines and the Nástup Tušimice Mines. The company's business line includes mining, processing and selling brown coal and associated by-products. The company's domestic market share in 2008 was 46.87%. The Nástup Tušimice mine is the most important mine for brown coal excavation in the Czech Republic. In 2010, approximately 12.3 million tons were extracted, and in 2011 more than 15 million tons are expected. Since 1979 the mine slopes have been monitored with Leica Geosystems equipment. In September 2011 Severočeské doly a.s. decided to renew its monitoring equipment for the latest Leica Monitoring Solution. more
Gateway to Korea
The Yeong-Jong New Airport Highway Bridge, a steel, double deck, box-girder suspension bridge, links Incheon International Airport to Seoul city as a real gateway to Korea. It is the world’s first 3D self-anchored suspension bridge servicing a highway on the upper/lower decks and a railway on the lower deck. The bridge crosses the sea between Yeong-Jong island and Incheon city and lies between Kyeongseo-dong (Changdo) and Unbuk-dong (Yeong-Jong island) of Incheon city on the Yellow Sea. Leica Geosystems was invited by the New Airport Highway Company to perform a load test with GNSS RTK technology. Equipment and software completed the test smoothly, achieving impressive accuracies in the range of 1 cm. This load test convincingly vindicated the superiority of GNSS based bridge monitoring. After the test the upgrade and modification of the structural health monitoring system was completed using a GNSS monitoring system from Leica Geosystems that focuses on monitoring the girder geometry and the displacement of e bridge towers. more
Tunneldrive Scanning with Leica HDS6000
3D laser scanning has become established in many applications over recent years due to its potential for rapid, non-contact data capture at a high scanning density. That this process can also be used successfully for the investigation of deformations of large surfaces is demonstrated by a research project at the Technical University Munich, Germany (TUM). The Leica HDS6000 laser scanner proved to be a success when scanning the area around the working face of an extension tunnel to the underground railway system in Stuttgart. more
