A key safety issue in the operation of any nuclear reactor or nuclear waste management site is the control and containment of radioactive material, making risk assessment and management by means of regular inspection a vital element as much as a regulatory requirement.

Given the challenges of working in radiation controlled environments and with limited choice of non-contact, remote examination techniques available, visual inspection has so far been most widely used technique despite its limitations to the detecting of obvious flaws, requiring good eyesight and illumination, and findings are often subjective and dimensionally uninformative.
In recent years, remote deployment of laser scanners in contaminated environments has allowed acquisition of more precise survey data. By the systematic emission of millions of laser beams, a 3D Laser Scanner (e.g. FARO’s Focus3D) collates accurate measurements of distances to objects, producing a 3D model often referred to as the “Point Cloud”.

The German industrial manufacturer Siemens is well equipped with a number of FARO arms to speed quality control and increase production flexibility in the Large Drives Business Unit.
The German-based industrial multinational Siemens needs no introduction as a global leader in drives, automation, transport, building technology, lighting and industrial solutions. Within the Drive Technologies Division, the Large Drives Business Unit makes motors and the associated transformers and control components that are found in railway locomotives. Further products include drive systems for machines used in the textile, packaging and printing industries.
About 210 employees are involved in the unit’s mechanical manufacturing department on Vogelweiherstraße in Nuremberg. Supporting them is a team of 8 metrologists in the quality control / measuring department. In 2005, they acquired their first FaroArm Platinum, to replace a conventional 3D coordinate measuring system and a range of manual methods. Excited by the substantial timesavings, Siemens added another four FARO arms when the Quantum became available.
Construction monitoring is one of the key applications of the 3D laser scanner. Starting with the inspection of the foundation excavations through to the weekly monitoring of the building shells, the laser scanner enables time and cost-efficient working. Any discrepancies between the building under construction and the existing plans are monitored. In this article we show how the laser scanner helps with construction monitoring and the advantages that are offered by the laser scanner compared with conventional measuring instruments.
Monitoring the progress of an office building using the 3D laser scanner
A job in the construction industry might involve monitoring the progress of an office complex. The excavation for the foundations has already been completed. The client requires weekly documentation and monitoring of construction progress for legal and technical documentation. The property is a modern design with lots of free-form surfaces. Conventional measuring instruments cannot measure it comprehensively. Laser scanners are predestined for this purpose. They are also suitable for documenting any discrepancies between the existing building and the planning documents. Laser scanning saves time and money. With the appropriate software it is also possible to produce new plans if necessary.
Building Information Modelling is the biggest change in the construction sector, since CAD replaced hand drafting. Existing Building Information Modelling (eBIM) is the first step in the BIM workflow for retrofit & refurb projects.
BIM was developed as a way of managing the full development lifecycle of a building project. Used to facilitate new designs, build changes and communication amongst contractors and design teams, it has provided significant cost savings and efficiency gains. As these methods have become more robust, companies have looked to apply these techniques to a range of projects. Combined with the current downturn in the new build sector, many firms have seen the majority of their construction work switch to retrofit and refurb projects instead of new build. [Read more …]
Phil Harding goes face to face with the FARO Laser ScanArm!
Discover in this astonishing video one the many applications of the FARO ScanArm: the live scanning of a human face. Phil Harding is a prominent British field archaeologist who has become a familiar face on the Channel 4 television series Time Team. This series features a team of specialists carrying out an archaeological dig in three days and explaining the process in layman’s terms.
Paleontologists from the Sam Noble Oklahoma Museum of Natural History are working towards reconstructing the anatomy of missing bones of a juvenile Apatosaurus. With approximately only 15% of the bones collected, scientists look to digitally reconstruct the rest of the bone structure using the model of the adult Apatosaurus currently on display in the Museum. Reverse engineering the large skeleton would be the best solution.
The Sam Noble Oklahoma Museum of Natural History is home to one of most extensive paleontology collections of prehistoric specimens. Much of the scientific research for the museum is conducted by the Center for Shape Engineering and Advanced Manufacturing (SEAM). SEAM is a multi-university collaboration that has pooled together engineering resources to focus on creating and disseminating innovation. As one of SEAM’s members, the University of Oklahoma has been recently working with the Sam Noble Oklahoma Museum of Natural History in a very unique application.
The paleontologists of the museum were tasked to reconstruct the anatomy of a juvenile Apatosaurus. Since only 15% of the bones had been collected, the remaining fossils would have to be anatomically created by the team of scientists. Traditionally, sculpting clay models by hand has always been common practice. However, using this process is extremely time consuming, often inaccurate and highly irreproducible.
As part of SEAM the University of Oklahoma assisted the museum’s paleontologists by providing an alternative solution. The university’s objective was to provide individual prototypes of each individual bone of the juvenile Apatosaurus for the paleontologists to create castings for the display model. The team decided to reverse engineer the current adult Apatosaurus skeletal model so they could proportionally create the missing bones of the juvenile dinosaur.
Congratulations to Corvette Racing for their historic victory in the most grueling race of the season, the 24 Hours of Le Mans! The win came as Chevrolet celebrates its 100th anniversary and the 10th anniversary of Corvette Racing’s first Le Mans victory in 2001.
FARO is a proud sponsor of Corvette Racing and a long-time partner with Pratt & Miller Engineering. Corvette Racing, which is run by Pratt & Miller, has used FaroArms in the design, quality control and race-specification compliance of their vehicles; the Gage validates parts in their precision machine shop; and the ScanArm reverse-engineers components. This allows the company’s engineers and technicians to accurately and efficiently produce everything from small, individual components and sub-assemblies to complete turnkey road and race cars.
Pratt & Miller used the FaroArm, FARO Gage and FARO Laser ScanArm in order to design, construct and analyze ‘virtual’ components, CFD (computational fluid dynamics), systems, and complete cars – every facet of a project from initial conception to the finished product. The combination of Pratt & Miller team’s expertise and FARO’s portable, computerized measuring technologies offers a total design solution, so Pratt & Miller has unmatched time and cost efficiencies, accuracy, and performance.
Architects and civil engineers require millimetre-precise survey data for their work. With traditional measuring devices the measurement of a building or site is a tedious and complex process. Modern 3D laser scanners are time-saving and cost-efficient – and not only in the field of architecture. In our blog we will introduce you to this innovative technology.
3D laser scanners: tomorrow’s survey technology
For a long time yardsticks, spirit levels and theodolites were the only option for measuring buildings or sites. Surveying was simplified by laser measuring devices that indicated the distance between two points. With modern 3D laser scanners it is now possible to measure a real building and construct a virtual model in just a few steps. The leading laser scanners record up to one million data points per second. Within a few minutes they create a complex image of their surroundings. Architects’ drawings, floor plans and elevations etc. can be created with the survey data. The 3D laser scanner technology is quicker and more cost-efficient than conventional methods of documentation.
This is the conclusion of a study delivered by Professor Schulmeister, laser safety expert from Seibersdorf Laboratories in Austria. The FARO Laser Scanner Focus3D is classified as Class 3R under IEC 60825-1 Ed 2.0. An analysis of the exposure levels of the eye for realistic as well as unrealistically conservative exposure conditions shows that the exposure is below injury threshold levels for the retina. It can therefore be concluded that exposure of the eye that can be expected to occur would not induce ocular injury. [Read more …]
The use of enhanced reality has rapidly become part of everyday life. This new technology, which enables the superimposition of virtual elements onto reality, is rapidly gaining in popularity. In the cultural heritage sector and museums, it opens up new options for presenting sites and works of art. It is thus possible to display missing or lost elements, to provide complementary information, and to reconstruct historical scenes and décor in a manner that is at once spectacular, playful and educational. ART GRAPHIQUE ET PATRIMOINE (AGP) uses FARO for exceptional presentations. One example is the enhanced reality replication of the study of Charles V, at the Château de Vincennes, as it was in the 14th century.
