Bridging the Gap between Geospatial and Construction

There is certainly a gap in information exchange between the geospatial and construction domains. This is a serious issue, mainly because geospatial systems and engineering surveys are not yet aligned and integrated with building information modelling (BIM). The BIM method is expected to move construction activities from plan-based individual work to model-based collaboration. Such a paradigm shift will bring huge opportunities regarding planning, building and management of the built environment in a more productive, open and sustainable way. Although it is still difficult to entirely close the gap between these two fields, this article shows how that gap can at... (read more)

The Rising Demand for Total Stations and Terrestrial Laser Scanners

How the Booming Construction Business Boosts the Geospatial Industry
Increasing investments in large infrastructure and construction projects, and the rising role of building information modelling (BIM), are expected to drive the market for geospatial equipment. BIM’s close connection with spatial information makes it a familiar landscape and offers rich possibilities for surveyors and other geospatial professionals. Geomares – publisher of 'GIM International' and 'Geo-matching' – has analysed the user data and behaviour of thousands of members of the global geospatial community. It is interesting to see how the market of ‘traditional survey equipment’ such as total stations and terrestrial laser scanners is responding to the growing construction market and... (read more)

Home Renovation Made Easy with Handheld 3D Scanning

As residential real estate prices continue to climb in many parts of the United States, property owners are increasingly investing in renovations and additions to their existing homes. To meet the demand, architects seek digital as-built documentation of the structures, so they can design the new construction. Many are asking for mobile 3D scanning by name as the technology they prefer to quickly capture the accurate, comprehensive as-built detail needed to start the design work. Business is booming for Precision Property Measurements (PPM), a Long Beach, California, firm that has provided as-built documentation services to Architecture, Engineering and Construction (AEC)...

The Expanding Use of UAVs in Construction

Flying to Build a Better Product
It is an exciting time for geospatial professionals. The data that can now be obtained using unmanned aerial vehicles (UAVs, or drones) opens up previously impossible opportunities in many different industries. At the forefront of these is the construction industry. As a geospatial engineer working for a general contractor, Michael Schwind is always looking for new ways to utilize UAVs and the resulting data to improve efficiency and communication, and to detect and prevent costly – or even deadly – mistakes before they occur. In this article, he discusses some of the obvious and not-so-obvious ways that Fulton Construction, a... (read more)

What's the Difference Between SLAM Algorithms for Handheld Lidar?

While researching handheld Lidar scanners, you will probably scour spec sheets, cross-reference features, and read about software workflows. But that will get you only part of the way to understanding the market – you will also need to compare the simultaneous localization and mapping (SLAM) algorithms that power these devices and enable them to create a point cloud as you walk. The problem is that SLAM algorithms can be difficult to understand if you're not a software engineer. Good news: There are a few criteria you can use to judge SLAM algorithms. These criteria will help you understand what sets... (read more)

Seeing the Future: AI, BIM and Digital Twins

Digital Construction Week 2019
During Digital Construction Week (DCW), which was held at the Excel in London from 16-17 October 2019, there was one seminar stream on geospatial surveying and two specifically on building information modelling (BIM). But relevant topics such as artificial intelligence (AI) and visualization, as well as BIM, cropped up in many of the other sessions. The most used buzzword was 'digital twin', which was heard in many talks and in the exhibition booths. The term digital twin is used quite flexibly, but essentially it implies that an object must have a digital representation which can be presented visually, i.e. a virtual... (read more)

5 Questions to... HÃ¥kan Engman, Bentley Systems

What makes the digital city so relevant for geospatial surveyors, and what lies ahead for 3D city modelling? We asked these and a couple of other questions to Håkan Engman, the director of business development in the digital cities business unit at Bentley Systems. In that role, he is leading business management activities for OpenCities products. He is also responsible for the integration of the Swedish company Agency9 following Bentley’s acquisition of it in September 2018.  The ‘digital city’ or ‘smart city’ is a hot topic. What makes it so relevant for geospatial surveying professionals? In most cases, smart initiatives... (read more)

Ordnance Survey Demonstrates BIM Potential with Pioneering Project in Singapore

By combining building information modelling (BIM) with geospatial technologies, Ordnance Survey (OS) is breaking down barriers in Singapore. OS has spent two years in the Southeast-Asian nation championing the use of BIM data and its potential to transform urban planning. Britain’s mapping agency lent its expertise to a project with the University of Singapore and the Singaporean government that aims to make Singapore a world leader in smart technology. OS’s role was to develop data processing and 3D data modelling to help Singapore plan its future city more effectively. It contributed knowledge about the CityGML data model, an exchange compatible with... (read more)

Construction Economics is Fundamental in Responding to Coronavirus

How Improved Project and Cost Management of Construction is Critical to Recovering Economies
Global construction will be critical in countering the economic effects of coronavirus. Whilst most construction has been adversely affected in the short and medium term by closing sites, social distancing, material shortages and investment uncertainty, it will provide an important stimulus to the world economy if governments enable projects to proceed after the virus abates. Coupled with this, the crisis is providing a catalyst for change in the industry in terms of the greater adoption of technology, consideration of sustainability and social value impacts, and greater collaboration. Construction allows value creation – and the world will need this more than... (read more)

The Evolution of the Smart Surveyor

5 Trends Affecting Surveying, Bringing about the Next-generation Surveyor
Surveyors are a versatile and flexible bunch. As the current COVID-19 situation has proven, this group, like others, has had to find new ways of operating. As illustrated by this article itself, which was originally planned as a presentation called 'Sensor Fusion for the Smart Surveyor' at the International Federation of Surveyors (FIG) Working Week 2020, adapting to a new platform for information sharing is becoming the new normal. In FIG Commission 5 – Positioning and Measurement and FIG Commission 6 – Engineering Surveys, the focus is an ever-evolving adoption of new technologies and integrating methods with various instruments and...
