  • Leica MS60 MultiStation Use on the Ordsall Chord Network Rail Project in Manchester

    The Ordsall Chord is a flagship Network Rail project in Manchester City Centre and involves the construction of 7 new spans, 300m of new track and the widening of existing Victorian viaducts.  At the centre of the project sits the iconic network arch bridge, the first of its kind in the UK, spanning 90m.  The new link will allow trains to run between Manchester’s Victoria and Piccadilly stations for the first time.

    SCCS – The Survey Equipment Company operates as a preferred supplier to Skanska and have worked in partnership on the Ordsall Chord to successfully deliver equipment, technical support and training. Since the preliminary stages of the project the team have provided assistance with commendable performance, regularly going the extra mile to meet the projects requirements at short notice.

    The use of the Leica MS60 MultiStation has added significant value to engineering and surveying procedures as well as delivering significant time savings on the Ordsall Chord project. Much of the design of the Ordsall Chord project adopts complex geometry to deliver architectural features such as fanned pier extensions. These complex structures meant traditional checking throughout the construction process which would have been challenging. The adoption of the Leica MS60 allowed us to develop an innovative process of scanning and verification/clash detection to reduce risk and streamline the QA process. The Leica MS60 even delivered time savings over modern dedicated laser scan systems, this is where there is a requirement for small amounts point cloud data regularly when captured in conjunction with traditional site engineering and surveying duties.

    On a rail project such as the Ordsall Chord, limited access to track means time on track is precious.  Having the ability to complete a quick scan with our multi station has delivered unforeseen benefits through as built point cloud information as previously additional track visits would have likely been required.

  • Collaborative CAD system workflows for large HDS data projects

    An interview with Phil Marsh on the advantages of using Leica JetStream to improve the transfer of data across numerous platforms.

    Hi Phil, please give us a short overview of yourself.

    I am the HDS manager at SCCS where I have been for 6 years, and as the specialist in laser scanning and 3D modelling for land and measured building surveying I provide sales and support to all of our customers. During my career I have gained experience with modern TPS, GPS and HDS surveying equipment and knowledge with topographical and internal measured building surveys using Leica laser scanning hardware such as the new ScanStation P30/P40 and the software Leica Cyclone, CloudWorx and 3DReshaper.

    Leica JetStream

     

    You’ve chosen to talk about the Leica JetStream software. Why?

    Leica JetStream is a streaming data server for HDS projects and in a nutshell it speeds up the scanning workflow. It allows scan data to be sent to other users and clients very quickly. As point cloud data is typically huge in file size, sometimes terabytes of data, trying to distribute this to multiple users via file transfer or manually by disk can be a real nightmare. Instead, Leica JetStream compresses and circulates the captured point clouds to other users who can then load and render instantly.

    So what are the benefits of Leica JetStream?

    Speed, definitely. When integrating into projects the work flow speeds up no end. As the indexed data gets optimised and reduced by up to 10 times in size so it’s quicker to work with. It also saves on storage space and as the data is managed from one location there’s no duplication or mistaking the information.

    This adds the obvious benefit of being easier to collaborate on projects and when working as a team. As I mentioned, the data is stored in one location such as a cloud services like Amazon and Google which can be accessed by multiple users at any time, across networks so ideal for unlimited sized groups.

    Also, it loads projects instantly and gives super-fast rendering for CAD users who really will appreciate the benefit. Full density point cloud rendering all done in real-time, which speeds up panning, zooming and other interactions. All users hate waiting for rendering to complete and JetStream slashes this. It also means it’s ideally suited for the advanced Leica P30 and P40 ScanStations.

    Any other advantages?

    Its scalability means it can accommodate single users to large groups and the extra available components are very affordable and on subscription, meaning users can be more flexible with adjusting their costs.

    Who can use Leica JetStream?

    Leica CloudWorx users and CAD companies mostly. Anyone using AutoCAD or anyone integrating a 3D point cloud data. Generally I suppose the entire CAD community.

    What makes Leica JetStream unique?

    I suppose its main unique pro is to be able to connect with all Leica CloudWorx plugins and in the future will be developed to connect with Leica Cyclone modules too.

    Thanks very much for taking time out to do this Phil.

    FAQs

     

    What separates the Leica DS2000 from other utility detection GPRs?

    The Leica DS2000 is a robust, user friendly system. It features two frequencies meaning that it’s able to comfortably look into both shallow and deeper ground at any one point. This means you’re able to clearly see both shallow and deeper services on the screen at the time of acquisition.

    ---

    On average in the UK & ROI, what would you say is the deepest you can see to effectively locate utilities?

    This is variable as ground conditions aren’t the same everywhere – however, on average I’d say anything between 1.5 – 2.5 meters.

    ---

    If I’ve used a DS2000 GPR on a project, does this mean I wouldn’t need to use an Ezicat & Genny or vice versa?

    No, in accordance with PAS128 these are two separate steps in utility detection. You can miss things with an Ezicat that you wouldn’t necessarily miss with a GPR – for example: plastic pipes that carry water or gas.

    ---

    Utility surveying is a new service provision to our company, we’re not in a position to invest in all of the kit until demand picks up. Is there an alternative to purchasing a system straight away?

    Of course, SCCS has a big rental fleet with competitive rates for both one off and long term hire periods.

    ---

    What do I need to know before if I purchase or hire a DS2000?

    Nothing necessarily, we can provide you with comprehensive product training and also give you an understanding of what different features look like in DS2000 data.

     

    Do you provide customer support for the?

    Yes, all you need to do is give SCCS a call or email for any queries on how to use the GPR.

    ---

    Our client hasn’t stated whether or not they want the services marked on-site or if they want a paper trail?

    No issue, any data recorded with a DS2000 is automatically saved to the tablet (PC). Once a GPR survey is finished you can print out a PDF survey report which will contain information on the completed survey.

    ---

    Can you use GPS with GPR?

    Absolutely, you can use the DS2000 with or without GPS. We can provide you with a GPS system that talks directly to the software. Alternatively, you can use your own system as long as it meets the minimum requirements ($GP GGA, serial port or Bluetooth connection, and a minimum of 5Hz).
