It’s simple, reliable, powerful and really does live up to its ‘New Generation’ tag

As the smallest and lightest receiver in its class, the Trimble R10 is all about increased productivity, combining powerful features and innovative technologies including:

Trimble HD-GNSS - ground-breaking addition that provides a more accurate assessment of error estimates than traditional GNSS technology, especially in challenging environments. The result - vastly reduced convergence times that, in turn, reduce your occupation time when collecting high position and precision reliable data.

Trimble SurePoint - provides users with faster measurements, increased accuracy, and greater quality control thanks to an electronic bubble that appears on the Trimble controller display.

Trimble 360 - supports signals from all existing and planned GNSS constellations and augmentation systems - an unparalleled 440 GNSS channels.

Trimble xFill - continue surveying without interruption, even if you temporarily lose connection to your base station or Trimble VRS due to working in poor signal areas or challenging environments. A worldwide network of Trimble GNSS reference stations and satellite data-links ensure that Trimble xFill works to seamlessly ‘fill in’ gaps in your RTK or VRS correction stream.

The R10 is also featured in this issue’s KOREC customer story on Mark Humphrey of Land and Satellite Surveys and his work at London Gateway as the project’s ‘on call’ surveyor. nnn

SnakeGrid supported in Access SnakeGrid was originally developed by Dr Jonathan Iliffe and his team at UCL’s Department of Civil, Environmental and Geomatic Engineering to overcome the surveying issue of the effects of scale factor and height distortion when applied to linear coordinate systems, sometimes many hundreds of kilometres long. This problem is particularly noticeable in the rail environment when surveyors and engineers are using different positioning systems such as Total Stations, GPS/GNSS, Lasers and to coordinate control and measure engineering and asset information.

Effectively Total Stations and digital survey and design data work in scale factor 1 and GNSS does not; SnakeGrid bridges

that gap. It allows survey control measurements from GNSS and Total Stations to be combined

into a single project file. This means that when any measurement professional is working on that project, they can all use the same coordinate system with a 1:1 relationship between digital data and measurements on the ground.

There are many SnakeGrids across the UK rail network and many projects have it written into the specification. For more

information please visit www.snakegrid.org

The great news is that if you need to measure in RTK mode live on a SnakeGrid site you now can with Trimble GPS/GNSS as Trimble Access now supports the SnakeGrid parameter file. Anthony Mills from Trimble explains:

“SnakeGrid is now implemented in Trimble Access and can be used right

now. It can also be used in conjunction with Trimble VRS Now. Although SnakeGrid is suitable for Roads, Pipelines and Rail, we see it very much as something for rail and a great

example of a tailor made application for a specialist market and of particular relevance for UK users. Trimble is the first company to implement SnakeGrid into a field solution.” nnn

Drowned TSC3Trimble TSC3 logger survives 6 day immersion!

We’re always delighted to hear from you about your surveying experiences first hand. This issue, it’s thanks to Paul Haydon of Brunel surveys for the finest kit ‘survival’ story yet!

“Last week one of our members of staff was about 75% of the way through a 2 day survey of a farmyard. One boundary was a large stream, in flood, and about 1.5metres deep. Needing something from his van, he lent the detail pole against a fence.

The detail pole slipped, fell into the water and was last seen floating down stream complete with a 360 prism and Trimble TSC3 datalogger. The job had yet to be backed up.

A week later another surveyor went to the site armed with waders, life jackets etc to re-do the survey and look for the missing kit. By now the stream was only about 6 inches deep and the kit was quickly spotted and rescued. On the off chance, our surveyor tried to Bluetooth the wet datalogger to his own. Lo and behold it worked and he extracted all the data before carrying on with his own kit to finish his survey.

One day later he took the drowned datalogger, turned it on and connected it to an instrument - it worked perfectly. There you are, a TSC3 can stand immersion for 6 days in water up to 1.5metres deep!

KOREC Rail New: Trimble GEDO Scan SystemKOREC is delighted to be selling the Trimble GEDO Scan System, a modern, efficient tool to collect detailed information about track and surrounding features. With Trimble GEDO 2.0 Scan you can quickly gather precise, high-resolution data for use in track clearance assessments and facilities management.

How it works

The Trimble GEDO 2.0 Scan system utilises a Trimble TX5 3D laser scanner to collect rich datasets of 3-dimensional points. The scanner is mounted on the new, lightweight GEDO 2.0 TMD, which collects 3D track geometry information including cant and gauge as it is pushed along the track. The track and scan data can then be combined to produce detailed 3D models of structures including tunnels, overpasses and stations as well as other important features like vegetation, embankments and general rail infrastructure where detailed information is needed for railcar clearance and asset management.

The Trimble GEDO Scan Office software combines data from

GEDO Rec and GEDO Scan field software to produce a fully rectified 3D point cloud. This 3D data can also be shared with Trimble RealWorks and other design systems.

Key features include:

n New lightweight, easy to use, self-contained TMD used for Trimble GEDO Scan and other GEDO applications including alignment stake-out and tamping

n Helical scanning mode captures 305 degrees of data in cross-section allowing ceilings, walls, track and even ballast to be surveyed and highly accurate 3D models of tunnels, overpasses and other infrastructure to be created

n GEDO Scan Field software runs on the rugged Trimble Tablet controller. This user-friendly field software controls scanning operations and data collection from the scanner, TMD and GNSS or Total Station. The system can be used as a stand-alone to capture relative 3D point clouds or combined with a Total Station or GNSS to capture fully geo-referenced 3D point clouds.

n The workflow and user interface are consistent with other GEDO systems to reduce training and increase system productivity and return on investment. The modular nature of the system lets you use the Trimble TX5 3D laser scanner for other survey work too, improving flexibility.

Customer story

A New Port for LondonConstruction on England’s new seaport requires rapid response to a multitude of surveying needs. Here’s how Mark Humphrey of Land and Satellite Surveys handled the load with his new Trimble R10

Just east of London, on the north bank of the Thames Estuary, lies a newly formed piece of England.

Thanks to a massive offshore operation that includes a dredger sucking up sand and silt from the Thames riverbed, a parcel of new land has been created on the north bank of the Thames Estuary 40 km east of central London. And it’s on this new land that the UK’s first 21st-century major deep-sea container port—and Europe’s largest logistics park—is currently being built.

Owned and operated by DP World, London Gateway is a brownfield development that will create a completely new, state-of-the-art facility for shipping and distribution. With a projected cost of £1.5bn (US $2.35bn), the new port will feature six berths and the capability to handle Ultra Large Container Ships. These massive ships can carry over 14,000 twenty-foot equivalent units (TEU) of containerized cargo. (A TEU represents the volume and dimensions of a single standard 20-foot shipping container.) The port and newly dredged river channel will offer the terminal infrastructure that the immense vessels demand, including channel and berth depth, bridge height, quay crane height and boom length, and inland and terminal logistics networks. The new port will dramatically increase the container handling capability of the Port of London, and is projected to attract new businesses and jobs to its modern logistics and distribution facilities. London Gateway will use a multi-modal approach to connect deep-water shipping to the UK via smaller ships, rail and roads.

Looking after London Gateway’s land and engineering survey requirements on the inland “Park Side” of the site is long time KOREC customer, Mark Humphrey of Land and Satellite Surveys (L&SS). The primary focus on the Park Side of the site is to prepare the area for roads, rail and buildings. L&SS is contracted to support the many divisions of London Gateway. On a daily basis Mark can undertake anything from setting-out and volumetric surveys to as-built surveys or preparing CAD drawings and machine control models.

Faced with the need to be mobile and ready to work at short notice on any part of the 2 km-long site, Mark elected to carry just one survey instrument – a Trimble R10 GNSS system supplied by KOREC. By using the R10 system with either a local RTK base station or the local Trimble VRS network for RTK corrections, Mark gained the versatility, accuracy and reliability he needed for the array of tasks he would perform. He has used Trimble VRS for all of the project’s high-accuracy work including control, checking and verifying other contractors’ control. The L&SS base station—one of six on the site—is used for machine control. In addition to L&SS, multiple contractors on site use Trimble equipment for construction activities.

Site Challenges

While part of the project will be built on the new land, much of it will be built on reclaimed salt marshes. In this

area, the existing site needed to be raised by 2 m throughout in order to lift it above the flood plain. The required fill material has been taken either from an old refinery site on the project or from the river during the dredging process. In both cases, a large part of Mark’s work involves volumetric surveys.

It’s a dynamic site, and delays are costly. As Mark moves around a stockpile (each volume survey typically calls for 1,000 points or more), the size of the stockpile sometimes interferes with the radio link to the base station. When this occurs, the R10 GNSS system with Trimble xFill™ technology can kick in automatically to “fill in” the gaps, allowing him to continue RTK surveying without interruption. Humphrey credits the xFill technology with keeping survey downtime to a minimum.

An additional challenge has emerged from the area’s previous life as a Shell oil refinery. Dotted 1,500-acre site are more than 80 old petroleum tank bases, many of which are buried. In each of these bases are anywhere between 600 and 1,500 piles, each with a diameter of 60 cm. In preparation for future building piling and construction, L&SS needs to measure and record each pile’s elevation and position to 20 mm accuracy

Undeterred by the lack of information on the locations of the tank bases, Mark used Internet research to discover an old post-war drawing of the refinery. He overlaid this data into his design software and adjusted it to fit an Ordnance Survey grid.

The end result was a huge boost to the search for the tank bases, with the new drawing proving to be accurate to within a couple of meters. Concentrating on eight of the tank bases in the most prominent positions, Mark needs to operate as quickly as possible. To do so, Mark configured his system to use Trimble SurePoint™ technology to automatically record a point when the pole is plumb and steady. This approach utilizes the system’s eBubble, an electronic level sensor that replaces the traditional liquid vial. The eBubble senses the pole position and displays an electronic “bubble” in the Trimble Access field software running on Humphrey’s Trimble TSC3 controller. “The light weight of the R10 means that I can manage it easily with one arm,” Mark said. “The eBubble shows me clearly when an accurate

measurement is possible. I’m operating on my own and I now have a free hand to operate the spray paint I need to mark each recorded pile because the point has been recorded automatically for me. This has hugely accelerated what is a long and repetitive task.” Mark estimates that the eBubble feature of the Trimble R10 has sped up the survey of the piles by more than 30 percent.

The site is also challenging in that no up-to-date mapping exists. As a result, it’s not unusual to discover obscure objects, areas of contamination and unknown pipe work. Using the controller, Mark emails coordinates of these “surprises,” along with a photograph taken with the controller’s built-in camera, as soon as he finds them. The rapid information flow allows London Gateway to react quickly and cut downtime that might result from the discoveries.

As an “on call” surveyor, Mark sees the seamless data flow between himself and the engineers at London Gateway as critical to his work.

“I’m here to collect, deliver and verify data and I can’t afford to have downtime. London Gateway appreciates a fast service and on all of these jobs, the data I collect need to be reliable and gathered quickly. The site has a number of quirks and the xFill capability and communications technology of the R10 has helped me out on many occasions. However sometimes it’s the simple things that really matter. With full days on a site of this size, the R10 has made it possible for me to move around the area quickly. I can work all day without the normal aches and pains of carrying kit around – definitely a first after a long day of surveying!”

The first phase of London Gateway is scheduled to open in the fourth quarter of 2013 with an initial capacity of 1.6 million TEU and will pave the way for 36,000 jobs to be created. nnn
