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 and 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... (read more)

3D Modelling for Property Valuation in China

A High-resolution Remote Sensing-based Approach
Rapid urban development in China has transformed the cityscapes, with a dramatic increase in high-rise buildings. However, the current 2D property valuation methods neglect the vertical dimension, even though that aspect contains significant indicators that impact property value – such as types of views, scope of vision and daylight. 3D modelling of geographical data can help to change this in high-rise and high-density areas, going beyond 2D to enable identification of complex property characteristics in the vertical dimension too. This article presents research to explore a 3D modelling approach using remote sensing data for more precise property valuation. The accelerating... (read more)

ISG Transforms 3D Model Delivery to Boost BIM Capabilities

Global construction services company ISG is using the latest 3D modelling technology to stimulate its building information modelling (BIM) capabilities. By introducing Pointfuse laser scanning software, ISG has speeded up workflows with rapid scan-to-BIM modelling whilst maintaining high levels of accuracy. Traditionally this laser data processing could take up to three days to 3D model a single floor. However, using Pointfuse, ISG has reduced this to a matter of hours. The use of Pointfuse has also increased the range of the point cloud outputs with applications including clash detection and visualization. “Scan-to-BIM modelling was previously seen as undesirable by the...

Dutch Partnership Designs "World's First" 3D Printed FPR Bridge

Royal HaskoningDHV, CEAD and DSM have announced that they have designed the first lightweight 3D printed FRP pedestrian bridge prototype using a composite material. It consists of a glass filled thermoplastic PET (Arnite®) and is combined with continuous glass fibres which are added in the 3D printing process. This unique combination offers high strength with extreme versatility and sustainability. Together, the three companies are leading a revolution in bridge construction and design. To build a 3D printed bridge Royal HaskoningDHV, an international engineering and project management consultancy, wanted and partnered with DSM, a global science-based company in nutrition, health and...

Rebuild Ready: 3D Mapping of a Quake-damaged Cathedral

After the cathedral of Christchurch, New Zealand, was hit by an earthquake, drones and advanced photogrammetry software supported the rebuilding work. Surveying a damaged building can be dangerous. Mapping, using drones, reduces risk to staff and costs to the community. This case study of the iconic cathedral of Christchurch, severely hit by an earthquake, demonstrates how drones and advanced photogrammetry software delivered the orthomosaic map, enabling the accurate spatial planning needed to rebuild the cathedral. In February 2011, New Zealand’s second most populous city was rocked by an earthquake. The iconic Christchurch Cathedral was shattered in the shake, and the clean-up is... (read more)
