Digitizing Reality: Automated 3D Point Cloud Data Processing Using AI

Intelligent Point Clouds
Instruments for digitizing the 3D real environment are becoming smaller, more lightweight, lower-cost and more robust. Accordingly, they are finding increasingly widespread usage, not only on surveying tripods for the highest accuracy, but also on mobile platforms such as autonomous vehicles, drones, helicopters, aircraft, robotic vacuum cleaners, trains, mobile phones, satellites and Martian rovers. Lidar uses laser scanning, while photogrammetry records images from one or more cameras which may be moving. Each laser scan records tens of millions of data point positions and colours in a point cloud, and hundreds of such point clouds may be combined. This article discusses... (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)

Leica Geosystems Enhances Construction Collaboration with Launch of BLK3D Web

Leica Geosystems, part of Hexagon, has launched BLK3D Web, an online collaboration workflow that extends the Leica BLK3D imager by enabling users to share 3D measurable images with anyone, anywhere online. The BLK3D device allows users to take precise, 3D measurements directly in the images it creates. Now, with a BLK3D Publisher license, those 3D image files can be easily and securely uploaded to the cloud. Once published, the 3D image files can be viewed and measured with BLK3D Web via a shared link, a simple and powerful tool used across major collaboration platforms today. “BLK3D Web in-picture measurements make...

What is 4D Construction?

As 3D building information modelling (BIM) continues to be the technology-enabled process for design delivery, construction firms have looked for ways to leverage these 3D BIM models for downstream construction workflows. Now, engineers are incorporating 4D modelling to their workflows. The concept adds a time dimension to the 3D CAD model that enables teams to analyse the sequence of events on a timeline and visualize the completion of construction tasks. This concept can be extended to 'nD', where additional dimensions represent other types of information added to the 3D model context. Engineers, construction managers, and contractors are leveraging 4D construction... (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...

Trimble 4D Control Software Provides Greater Geotechnical Sensor Support

Trimble has updated its core real-time monitoring software – Trimble 4D Control. Building on the recently released version 5.0, this update delivers support for Senceive’s wireless monitoring systems, streamlining the configuration process for users and delivering real-time data from geotechnical sensors to one common platform. By receiving data through Senceive’s wireless gateways into Trimble 4D Control software, project stakeholders can quickly and easily monitor critical infrastructure such as buildings surrounding construction sites, rail and tunnel projects as well as mines, dams and bridges. The announcement was made at Intergeo 2019, the world’s largest conference on geodesy, geoinformatics and land management.... (read more)

4D Construction Planning Saves GBP 1 Million on UK’s Largest-ever Water Infrastructure Project

The Thames Tideway Tunnel will capture and store raw sewage and rainwater from London’s 150-year-old sewer network, preventing overflow into the River Thames. It is the largest infrastructure project ever undertaken by the UK’s water industry. Bentley's SYNCHRO 4D workflow was used to streamline construction planning activities and to improve progress tracking and management. This has reduced the overall construction programme by 30 days, achieving GBP 1million in direct and indirect cost savings. The 25-kilometre-long tunnel is split into 24 construction sites, 11 of which are located along the river’s banks. The project involves 12 design disciplines and numerous supply-chain companies,...
