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)

InfiPoints 6.0: Modelling Directly from Laser Scans to Autodesk Revit

Elysium has developed an advanced functionality to model piping and structures from 3D laser scanned point clouds into Autodesk Revit. This new capability is included in Elysium’s point cloud utilization software, InfiPoints 6.0, which has been release on 30 September. The new feature allows Revit users to reduce their modelling time significantly. There is no need any more to create models of existing facilities from scratch. Furthermore, the CAD data extracted from point cloud data in InfiPoints is automatically imported into Revit to add finishing touches. Lidar technology Industry pioneers and some service providers have recently begun employing 3D laser... (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...

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...

Applications of Laser Scanning, Augmented Reality and BIM in Existing Facilities

The benefits of BIM in facility management are well known, but many buildings don’t even have a basic set of 2D drawings available. This is especially common in facilities that were built long ago, when computer-aided design was emerging or non-existent. Creating a smart 3D model of an existing facility from zero is possible, but the number of man-hours required and their cost can be considerable. While BIM is often associated with design, it can also be a powerful tool in facility management. This is especially true in large commercial or industrial facilities, where complex building systems are constantly interacting.... (read more)

Tackling Problems in Construction with Geospatial Analytics

The construction industry has always lagged behind in innovation compared to other industries, but geospatial data analytics is now set to transform construction, architectural design and civil engineering. Geospatial data analytics is location-based information generated by billions of devices around the world. The additional insights provided to engineers and architects can help the construction industry to cut costs and improve efficiency. Core problems with the construction industry To understand the gains made from data analytics, it’s important to explain the problems the construction industry faces. According to a report, construction projects take 20% longer to complete and go over budget by...
