Leica RTC360 3D Laser Scanner
Automatically pre-register point cloud data in the field to quickly conduct quality control checks, improve productivity and make better-informed decisions on site
The new Leica RTC360 laser scanner makes 3D reality capture faster than ever before. With a measuring rate of up to 2 million points per second and advanced HDR imaging system, the creation of coloured 3D point clouds can be completed in under two minutes. Plus, automated targetless field registration (based on VIS technology) and the seamless, automated transfer of data from site to office reduce time spent in the field and further maximise productivity.
Small and lightweight, the Leica RTC360 scanner’s portable design and collapsible tripod mean it’s compact enough to fit into most backpacks, ready to be taken anywhere. Once on-site, easy-to-use, one-button operation makes for fast, hassle-free scanning.
Low noise data allows for better images, resulting in crisp, high-quality scans that are rich in detail and ready for use in a range of applications. Combined with Cyclone FIELD 360 software for automated registration in the field, the Leica RTC360 scanner offers outstanding precision that can be checked on-site.
As part of the RTC360 solution, the Cyclone FIELD 360 app links the 3D data acquisition in the field with the laser scanner and data registration in the office with Cyclone REGISTER 360. On-site the user can automatically capture, register and examine scan and image data. The user interface combines easy handling of complex calculations with a graphical user guidance that offers a remarkable user experience, also for novice users.
Leverage the power of laser scanning for construction validation, coordination, and planning
Building projects move fast, and you need a solution that can meet these demanding deadlines. Leica Geosystems has designed inclusive a hardware and software solutions to gather and process data quickly so you can make informed decisions and keep your site moving efficiently.
From the robust high-range P-Series scanners to the Leica BLK360 and the all-new RTC360 Reality Capture Solution, we aim to empower everyone to plan and execute projects with higher quality.
But good data is only the beginning. Whether you are taking a single scan to validate the work of a subcontractor or conducting a detailed as-built survey for planning and coordination, our industry-leading software solutions make it simple to create digital reality deliverables. Professionals, who may have regarded the barriers of entry as too high in the past due to affordability and learning curves, can now fully benefit from laser scanning.
When an international retail group approached the Australian surveying firm, Project Surveyors, about creating a survey-accurate architectural and structural Revit model for the country’s second largest shopping centre, the firm was excited to participate. When the deadline was set for only 90 days later, Project Surveyors knew while future centre customers may shop till they dropped, the firm’s seven qualified laser scanning surveyors would be doing the same with 3D laser scanning.
The Sydney shopping centre is currently undergoing redevelopment, and the client needed a fully-parametric Revit Building Information Modelling (BIM) model for architects, engineers and facility managers to accurately plan the work needed. Covering a space of 375,000 square metres with vari-ous dimensional obstacles, such as cascading floors, topographic level changes and add-on buildings of diverse sizes, Project Surveyors faced one of its most complex jobs in its 43-year history.
“The enormity and complicated aspects to the building meant that our surveyors had to be meticulous when documenting scan positions and on field notes to assist in the registration of scans,” said Andy Jackson, Project Surveyors’ BIM Spatial manager. “With our Leica Geosystems instruments and soft-ware, we could ensure this.”
Scanning, modelling with confidence
Project Surveyors used a variety of Leica Geosystems solutions to capture, model and analyse the data. Starting with the Leica ScanScations C10 and P20, the surveyors were able to capture minute details. The Leica ScanStation C10 was used for the external facades and inside for large structures, such as the parking garages, due to its long-range capability. Inside, the Leica ScanStation P20 was used for its quality of producing fast reliable data at low resolution.
“The fast scanning time of the P20 helped us improve site workflow, increasing the number of scans per day fourfold,” said Jackson.
For survey control, Project Surveyors used the Leica TS15 and Leica MultiStation MS50. The Multi-Station was also used to scan windows for simpler capturing. Establishing a survey control network around the perimeter of the site and throughout the shopping centre at each level, these instruments ensured millimetre precision for aligning scans of the retrofitting construction. Laser scan targets were coordinated within the control network to maintain the accuracy of the overall point clouds.
A total of 3,700 scans from 55 days on site resulted from the project. The point clouds from these scans were cleaned and registered using Leica Cyclone 9.0. The entire process only took 20 days due to the addition of the auto-alignment registration within the software. Compared to point cloud-to-point cloud visual alignment, which would take around two minutes each to visually find common points, auto-alignment only takes 30 seconds to one minute.
“The time does not sound like much for a few scans, but when we’re talking about thousands of scans, this becomes a significant amount of time saved,” said Jackson. “With these savings, we were able to increase our productivity by at least 50 percent.”
The firm also used Leica TruView to provide the architects with the point cloud data so they could overlay in the model and have extra information, such as dimensions they needed to extract for accu-rate and realistic planning.
“Leica Truview images were a deliverable for the client, but they also helped the modeller to have a complete understanding of what they are modelling over,” said Jackson.
Autodesk Revit 2014 was used to model architectural elements while Autodesk Revit Mechanical, Electrical, Piping (MEP) was used to create pipes, plant, ducts and other services to create a partial MEP model of the loading docks. As the size and detail of this project would have taken one modeller 120 days to complete, Project Surveyors worked with a team of modellers in collaboration on one central model across a wired and large-data network.
Using the export option in Leica Cyclone 9.0, the surveyors exported the point clouds either separately as binary ptg files or unified as pts files. Autodesk Recap was then used to convert the files into Autodesk-compatible rcs files, which could then be inserted into Revit and modelled over. Using Leica Cloudwork for Revit, Jackson added that the exportation and conversion steps of the workflow would be eliminated, providing modellers with point cloud conversion tools as well as a single master data source rather than multiple files and versions of files to deal with.
“Using this laser scanning technology, we have won similar large projects, such as one in Sydney where we’re working with the same consultants who used this model as an example to the project owner of what they required as survey information,” said Scott Deveridge, Project Surveyors director. “Referrals to provide a similar service on another challenging project is the best feedback we can get.”
Lessons learned from HxGN LIVE
With attending HxGN LIVE 2014 in Las Vegas only a few months before the start of the project, Pro-ject Surveyors found the shopping centre project a valuable opportunity to put some of the lessons it learned at the international conference and exhibition to practice. Using these new ideas, the firm real-ised an approximate time savings of 75 percent.
Using scan-to-scan registration and auto alignment, the firm decreased its dependence on targets for every scan. The surveyors also used a lower resolution, kept the scanner operating between setups, and created a wheeled-transport tripod to relocate the scanner faster.
“Whereas before we were only able to collect about 16 scans per day, using what we learned from HxGN LIVE, we can now collect anywhere between 60 to 80 scans per day,” said Jackson. “We are also registering about 30 scans per hour, twice as much as before. This translates into significant efficiency gains, and therefore cost savings, for us.”
Returning to HxGN LIVE 2015 in Las Vegas, the project took top honors in the annual Leica Geosys-tems High-Definition Surveying (HDS) Plan Contest. A panel of 11 qualified judges evaluated 24 en-tries based on the completeness and usefulness of the plans, the creative use of point clouds and models, and overall appearance. Project Surveyors took first place with the project in the Build-ings/Heritage category.
“Our team has worked hard, and we are always looking for innovative ways to improve our business,” said Jackson. “Winning this award confirms our commitment to the profession and our dedication to the clients.”
A prime example
Another aspect of the Sydney shopping centre project is the innovative use of HDS in BIM. Through the use of a variety of HDS techniques in the field and in the office, Project Surveyors was able to organise and collaborate building information across an accessible platform.
“Using laser scanning in BIM helps us to have a complete understanding of what’s already there, what needs to be done, and how well the building process took place,” said Jackson. “Using laser scanning in BIM allows us to provide value-added deliverables to our clients.”
This project is an ideal demonstration of making the real digital world. As HDS captures the most current and accurate situation, professionals can then implement that data into software programs, such as Leica Cyclone or Autodesk Recap, to produce the realistic workable models. Exact adaptions can then be made so that when work is carried out on site, intelligent information is clear and error-free.
“The technology of HDS provides the tools and workflows needed to accurately and definitively cap-ture digital assets in minutes.” said Faheem Khan, vice president, business development manager for Leica Geosystems HDS. “Being able to capture, manage and deliver information and knowledge to all stakeholders underpins our strategy to provide the fastest, cleanest and most reliable hardware as well as a software portfolio that scales for all project sizes, disciplines and users.”

3D digital models with integrated functional characteristics has changed the way in which individuals, businesses and governments plan, design, construct and manage buildings and infrastructure. Building Information Modeling (BIM) has changed the way professionals in the architecture, engineering and construction industries improve coordination and reduce rework thanks to 3D intelligent models that are accurate, accessible and actionable.
Sertogal SL used Leica Geosystems’ laser scanning solutions to create a BIM model that will guide the remodeling and expansion of the electrical substation of Mera in the Spanish province of Ourense. This project is part of an ambitious initiative that will partly absorb the energy production generated by 17 new wind farms planned in the region.
To plan the remodeling and expansion of the substation, the first step was to measure its distances, angles and areas, with millimetric accuracy. Sertogal SL captured the substation with the Leica ScanStation C10 and georeferenced the point cloud obtained with the Leica Viva GNSS technology.
“We have worked for a long time with a wide range of Leica Geosystems equipment due to its great reliability and precision. The C10 ScanStation was no exception – it can be easily adapted to scan buildings, substations or electrical high-tension towers,” said Sergio Rodríguez, technical industrial engineer at Sertogal SL. “The laser scanner allowed us to capture the substation without entering in dangerous high voltage areas with risks.”
“The great precision and lack of noise in the generated point clouds permitted us to work in a complex structure with metallic elements and grids to obtain a BIM model that is a true representation of reality,” said Rodríguez.
The post processing, modeling and managing of the point cloud was done with Leica Cyclone, the market leader point cloud processing software. The rich as-built point cloud data from the substation was imported to Autodesk Revit to create the BIM model, and Autodesk Navisworks was used to insert and catalogue the elements into the BIM model.
The 3D intelligent as-built model Sertogal SL obtained from the point cloud of the substation:
This created the preliminary plans for the substation and the surrounding environment.
“The great volume of data obtained made possible a very accurate modelling of the elements and structures that are part of the substation,” said Bruno Sánchez Ucha, BIM expert at Sertogal SL.
The delivered BIM model of the substation allows stakeholders to take a digital tour that offers a complete outlook of the captured reality plus the visualisation of its different parts and elements with linked information.
Wires, tubes, isolators, circuit breakers and so forth, were embedded as intelligent elements and grouped in systems. This enables all parties involved in the remodeling to review how the projected substation developments will look like and how changes will transform the current space.
This intelligent model-based design process will help to start the renovations and manage operations in the future, and will drive workflows with accuracy and in a more productive way.
An increasing number of companies around the world understand the value and benefits of BIM across the lifecycle of building and infrastructure projects.
The rising demand for BIM projects has convinced Sertogal SL of the opportunity to position itself as a pioneer in Spain, offering BIM services for several maintenance and renovation projects.
Governments around the world, such as the Ministry of Public Works in Spain, are recommending, encouraging or mandating BIM, recognising the value and benefits it delivers:
Professionals have to be equipped with a laser scanner that delivers outstanding precision, rate, speed and data quality to create a BIM model. Leica Geosystems laser scanning technology helps create such a model that provides the right insights so managers can understand risks and make informed decisions to deliver projects responsibly despite time constrains.
