Bridging the Gap between Aerial Imaging and Terrestrial Data Capture

The Challenges of Drone Use in Facade Mapping
There have been rapid advancements in unmanned aerial systems over recent years, yet there is widespread consensus that we have still only seen a fraction of how unmanned aerial vehicles (UAVs or ‘drones’) could ultimately improve efficiency for geospatial professionals and their customers. To get a glimpse of the future, 'GIM International' spoke to Mark Nicolai, co-founder of industry start-up Aeroscan. Here, he shares his vision of how drones could form the missing link between aerial imaging and terrestrial data capture. According to independent research by the likes of PwC and Goldman Sachs, the construction industry tops the list in... (read more)

Technical Advances Bring Digital Twin of Underground Infrastructure Closer

Mapping the underground is one of the major challenges in creating an infrastructure map at the municipal, regional, and national level, which is a key foundation for a national digital twin. Recent technical developments include: the ability to collect data at highway speeds that can be used to create a 3D model of underground infrastructure, software that can extract relevant 3D underground information from consumer digital photography, and video capture. Meanwhile, novel ways to share information about underground infrastructure, and progress on standards for sharing information about the subsurface are making mapping the underground increasingly feasible. The uncertainty in the... (read more)

Powering the Future with Data and BIM - Digital Construction Week 2018

Digital Construction Week 2018 returned to Excel in October as an exhibition, with a main stage for paid conference sessions and several ‘theatres’ within the exhibition space. This article gives a taste of what was on offer over the two days. Real-time Asset Management The first day started with a 15-minute presentation from the Enable My team entitled ‘The Art of Raw Data’. This was all about using camera feeds from the front of trains to build up and maintain a real-time asset record. Apparently, cameras have been deployed for some time, but the data has not been used for... (read more)

The Role of Surveyors in the Evolution of BIM

Building information modelling (BIM) is becoming more commonplace within construction sectors globally, combining technology with improved collaboration to better manage projects and give them the best chance of complying with time and budget constraints. However, the BIM life cycle and efforts to espouse it are almost futile if surveying is taken out of the equation or, more realistically, brought in too late. It can be good to have a structure that is successfully using BIM to be delivered on time and within budget, but if it or any of its components are in the wrong position the consequences can be...

3D Modelling for Construction

When it comes to 3D modelling for construction, what are the advantages and disadvantages of photogrammetry versus Lidar in terms of accuracy, complexity and cost? Breaking away from laser measurement in construction is a taboo subject, perhaps hampering the use of photogrammetry. In construction, aerial survey has enormous time-saving benefits for measuring groundwork areas. Data can be used for asset classification, construction validation as well as health and safety. In particular, regular scans provide a time series of work in progress to detect new issues, managing risk rather than responding to it. This article looks at the state of the... (read more)

Everything You Need to Know about Scan-to-BIM

Scan-to-BIM brings the documentation of existing buildings into line with the modern digital planning methodology called building information modelling (BIM). This article describes how scan-to-BIM uses 3D laser scanning to digitally capture an existing building as a point cloud, for the creation and updating of a BIM model. The primary method of scan-to-BIM is to use 3D laser scanners to capture a high-density point cloud of a physical building, structure, or site, which leads to the creation and maintenance of a BIM model that reflects "as-is" conditions. Downstream applications for models made using scan-to-BIM can range from as-built documentation, project... (read more)

Expanding Horizons: Geospatial Predictions for the Coming Years

From New York to Dubai to Myanmar, more smart cities are springing up across the globe. As more countries start to digitally transform, the futuristic cities and state-of-the-art gadgets that once belonged only to the realms of science fiction may soon become our reality... and they will be made possible with the advancement of the geospatial industry. The global geospatial analytics market is estimated to be worth USD$134.48 billion by 2025, with the market registering a compound annual growth rate of 15% between 2019 and 2025[1]. Asia Pacific is also expected to see the highest growth during that period, fuelled by numerous... (read more)

The Paperless Construction Site

Digitalization is changing the construction industry faster than expected. But will we ever see paperless construction sites? Digitalization is changing the construction industry faster than expected. Automation, additional sensors and the networking of machines make it possible to exploit optimization potential and noticeably increase productivity. However, despite innovative working methods and digitization, the road construction process is still mainly based on one medium: paper. Will we ever see paperless construction sites? Paper can be used for a wide variety of purposes and offers unlimited flexibility. Construction schedules, work schedules, work sheets, mix orders and requirement slips are still created manually...

digitalBAU 2020: Bringing Technology and Industry Together

From 11-13 February 2020, Messe Köln – Cologne, Germany – will become a popular meeting place for the construction software sector. In the years between BAU, the world’s leading trade fair for the sector, there will be an important dialog platform for planners, architects, engineers, tradesmen and the industry as a whole. With a three-day trade fair, digitalBAU aims to bridge the gap between technology and industry. Through the event, the organizers, Messe München and Bundesverband Bausoftware e.V. (BVBS) are responding to the great demand for a platform for digital products and solutions in the construction sector. In addition to... (read more)

Penn State-led Team to Study Digital Modelling on Capital Projects

It takes a lot of data to move a large-scale, costly building project from design to reality. Digital modelling, otherwise known as building information modelling, or BIM, increases construction efficiency and saves time and resources on building projects by compiling large amounts of project data into a well-organized central repository.   John Messner, Charles and Elinor Matts Professor of Architectural Engineering at Pennsylvania State University (Penn State), is leading a US$240,000 Construction Industry Institute (CII)-funded project to study building projects that have utilized digital modelling and to compile recommended best practices for organizing, retrieving and analyzing project data, which often includes...
