Lidar Point Cloud Segmentation

A Novel Framework for Processing Terrestrial Lidar Data
Terrestrial Lidar data has great potential to produce measurements for as-built building information modelling (BIM). Unfortunately, processing hundreds of millions of points, often contaminated by substantial noise, can be tedious and time-consuming. Normal variation analysis (Norvana) segmentation is an automatic method that can segment large terrestrial Lidar point clouds containing hundreds of millions of points within minutes. Thanks to the high speed, point density and accuracy of modern terrestrial laser scanning (TLS), as-built BIM can be conducted with a high level of detail. But TLS captures not only useful geometric information but also unwanted objects, such as people, animals or... (read more)

Interoperable Data Exchange – A Key Factor for BIM

Interoperability is key in the building information modelling (BIM) context. Data diversity and interfaces, as well as possibilities for combining different data in BIM projects, are outlined in this article. Hardly any other topic dominates the digitalization of the construction industry with such intensity as building information modelling (BIM). The pressure to reduce costs and to plan and build more complex buildings faster and more safely is increasing due to international competition. Interoperable data exchange between systems and players is a key factor for BIM. Previously used data formats have to be brought together with newer formats that are constantly... (read more)

British Partnership to Deliver Detailed BIM-ready 3D models

Landmark Information has announced a partnership agreement with AccuCities, a 3D city models expert, to provide its 3D terrain and mapping models as part of a new subscription service. This will extend Landmark’s flagship mapping and location data service, Promap. The partnership enables architects, planners and developers to access highly detailed BIM-ready 3D models of UK-wide locations via a new 3D subscription service. The AccuCities 3D models are available in five layers – from a base model that offers an affordable option that is accurate to 200cm in all axes. This includes the main roof shapes of buildings in addition to... (read more)

Topcon Supports Improvement Works in Large UK Shopping Park

Situated on the southern edge of Leicester, Fosse Shopping Park is one of Britain’s biggest out-of-town shopping parks, attracting thousands of visitors each year. As part of a £155 million extension to the Fosse Shopping Park, McDermotts Building & Civil Engineering – a Chartered Institute of Building accredited construction firm – was appointed to complete the groundworks for the car park at the site, in preparation for a new surface to be laid. To prepare the land for the multi-million-pound works, McDermotts turned to Topcon Positioning to provide a solution with significant time-saving benefits. “We have an ongoing partnership with...

3D Scan Data Pioneer Scaled Robotics Secures €2m Seed Investment

Norwegian Construct Venture and German PropTech Fund Surplus Invest have jointly invested in the promising deep-tech company Scaled Robotics. The start-up has developed a robot that builds detailed 3D maps of construction sites using its multimodal sensor suite, and software that can accurately compare this data to the digital plans defined in the building information modelling (BIM) models.  Scaled Robotics’ solution allows detection of errors and deviations, which enables construction companies to identify potential sources of construction delays early in the process and put countermeasures in place. This results in massively reduced construction times and significant cost savings. Scaled Robotics has developed a product that can help significantly increase the quality and efficiency of construction projects.  The advanced technology, the positive customer feedback and highly competent founders in Stuart Maggs and...

How Can Surveyors Optimally Profit from the Digitalization in the Construction Industry?

How can surveyors optimally profit from the digitalization in the construction industry and the trend towards building information modelling (BIM)? Topcon, a global positioning partner for construction and geospatial businesses, sees BIM as not just a benefit, but a requirement. Here, Cesar Mendoza, the company's product manager for vertical construction, attempts to answer this question. He believes the UK government’s Construction Strategy, published in 2011, serves as a good example and has had a major impact on the uptake of BIM in the UK. The European construction industry is expanding at a rapid rate and is expected to grow at a... (read more)

Remodelling King's Cross Station

London’s King’s Cross railway station is one of the busiest stations in the United Kingdom, serving close to 40 million passengers each year. But it has been 25 years since any major intervention has taken place on the railway, and it's now in need of some major renewal and remodelling work. The remodelling will allow for an increase in the length and number of long-distance trains and facilitate future improvements to journey times. Specialist Project Integration (SPI) are undertaking this massive £250 million project which includes extending passenger platforms, recommissioning an unused tunnel, optimising the track layout and modernising the...

Accuracy Near, Far, Above or Under – How is FIG Working Week 2020 Contributing

The skills that engineering surveyors had to acquire in order to respond to the challenges of the construction world have made them capable, also, of fulfilling other challenges, several of which motivated by an awareness of the limitations of our planet. Engineering surveyors have learned that they need to push the equipment and techniques to its limits, while having recognized the necessity to integrate new techniques which can present more complete answers, without forgetting an important qualifier: accuracy. The instruments and methodologies have allowed for the surveying engineers to start working either very closely to the studied object, or, otherwise,... (read more)
