Highlights of the current issue are:
- Leica Geosystems Protects Venice
The 20th century has certainly endangered Venice’s ability to keep itself above water in the Venetian Lagoon. The city ever more frequently falls victim to intensive flooding, which not only reduces the quality of life for Venetians but also causes considerable damage to their architectural heritage. Following the evaluation of numerous alternatives the “Mose” project, an ingenious protection system, which includes adjustable floodgates, is now being implemented. A machine automation solution with GPS from Leica Geosystems has been chosen to ensure their exact positioning.
- Swedish Underground
One of the main requirements during the construction of the new Citytunnel in Malmö is to ensure that the surrounding buildings do not settle as a result of the tunnel driving works – as so often is the case with underground railway projects. Therefore daily monitoring surveys are carried out to allow immediate action to be taken should any buildings show signs of movement.
- In the Middle of the Rhine
The German energy provider “Energiedienst” is undertaking an ambitious project at Rheinfelden on the Rhine river. By 2011 four 6.5 metre diameter bulb turbines with an output of 25 megawatt each will be installed in the new turbine house on the Swiss side of the Rhine. One of the challenges is underwater excavation in the bed of the Rhine.
- Non-stop Paving
Often operating around the clock, Belgian civil engineering and building firm Betonac is using Leica PaveSmart LMGS-S on two slip-form concrete pavers. Runways and motorways are their main areas of application.
- Leica Builder in the “Green Industry”
Garden and landscaping company Dukat is very pleased with its new Leica Builder Theodolite with electronic distance measurement combined with a PDA and seamless interface to Dataflor CAD and other specialist landscaping industry software. Enormous time-savings and the ability to create drawings even without specialist knowledge of surveying have convinced garden and landscaping expert Jürgen Dukat.
- Rising High with GPS Network
The Burj Dubai is the highest-rise building under construction in the world. When completed in 2008 it will be the world’s tallest building, nearly twice the size of New York’s Empire State Building and higher than the current title holder, the Taipei Financial Center (Taipei 101) in Taiwan. The final height is being kept secret. Not a secret on the other hand, is the unique monitoring system Leica Geosystems developed together with the Chief Surveyor of Burj Dubai.
- Russia goes for Leica ADS40
The Russian National Research Institute for Cadastral Surveying, VISKHAGI, has a long tradition in the fields of aerial photography and cadastral surveying. Formed in 1932 as the Agricultural Aerial Photography Authority, it has been taking and working with aerial photographs for 75 years. Recently it has been using two Leica ADS40 airborne digital sensors. Sergey Alexandrovich Loginov, First Deputy General Director and Chief Engineer, writes about his experience for the “Reporter”.
- Earth Dam Monitoring with GPS Survey
The Karkheh is the third largest river in Iran by water yield, after Karun and Dez. In the past its water richness was a constant danger for the west and southwest regions of the country. Seasonal floods and resulting extensive damage were characteristic of the Karkheh river forpeople living in the region. So when Karkheh dam was completed in 1995 it was a source of great relief and huge benefits to the people. Using GPS to monitor this huge structure, which is among the world’s 10 largest dams, was a task undertaken by MahabGhods Consulting Engineers Company, situated in Tehran. The last eight years MahabGhods provided an accurate yet cost-effective method for monitoring the Karkheh dam in Khuzestan Province.
- Keeping Track of Moving Structures
How does a floodgate deform relative to the water level? What is the behaviour of the vibrations of a wind turbine tower? The Geodetic Institute at Leibniz University, Hanover sought answers to these challenging questions with the help of a Leica HDS4500 laser scanner.
- Beyond Scanning
At the end of 2006, CADWorx fieldPipe for Leica fieldPro was presented by Leica Geosystems and the software company COADE. It was launched together with the newest version of the mobile CAD software Leica fieldPro and is specially designed to build 3D plant models of existing piping systems. As-built models are created in real-time, on-site, and without any post-processing. Customer David Danko, laser scanning project manager with Falk Engineering & Surveying in Indiana, was among the first to try out the system. He told the “Reporter” about his experiences with the new package.
- Keep Up With the Youngsters
Todd Gokey is project engineer for Barrett Paving Materials Inc., the oldest contractor in the nation, established in 1864. Today the Syracuse, NY, division he works for does airport and highway reconstruction work, and for the past three months Gokey has been working with Leica Geosystems GPS indicate systems on two dozers and an automatic system on a Cat G12 motor grader.
- Sharp Lines on Site
With its outstanding optics and proven Power Range Technology™ the new self-levelling precision line-laser Leica LINO™ L2 is a little sensation. Its strengths: precise and perfectly visible laser lines. |
