Reality capture is a process of capturing as-is conditions as images or point clouds using various means, including laser scanners, LIDAR (light detection and ranging) sensors, 360º cameras, unmanned aerial vehicles (UAVs), and more. All of these different modes spit out different output files that can then be converted to usable point cloud or vector data. Extracting construction intelligence from the point cloud or vector data and sharing it in a consumable format is the key for the success of any reality capture process. This class will detail laser scanning and UAV data-capture and intelligence-extraction workflows for different use cases, such as quality control/quality assurance, construction planning, site logistics, data-rich 3D modeling, intelligent as-builting, construction progress reporting, and so on.
15 km metro line with 15 stations developed in Sao Paulo, Line 6 is the largest public-private infrastructure project under development in Latin America and one of Acciona’s largest project. And resuming it has its challenges. The size of the project, the complex and diverse city environment in which it takes place, the large network of stakeholders, and one extra challenge: a contract resumed after several years of being on-hold. BIM had been implemented across most disciplines, allowing a smooth resume helped by point clouds and our topographers, providing daily feedback to our Engineering team. With the help of Autodesk Docs as a CDE, we have achieved the transversality of information and it has become a key tool for: project review, design interface & constructability solutions. In times of pandemic, ACC has facilitated the coordination and collaboration between different teams and countries, ensuring that the key stakeholders had access to the latest data, anytime and anywhere.
While scanning technology is nothing new, improvements in its ease of use are expanding its applications. Using a Leica BLK360 scanner, two designers without prior survey or scanning experience captured a large portion of a wastewater treatment plant’s tunnels and connected facilities in four days, in preparation for a design project. New piping is to be installed in these existing facilities, which are already crowded with piping and equipment—a common scenario in similar long-established facilities. A rough routing drafted in Revit software was added to Navisworks software, along with the point-cloud files, enabling direct interference checks between the two without converting the point cloud to a model. Attendees will discover the detailed workflow they should apply to use this technology, and learn how it was used on this project in Ohio.
Come and learn how one civil group managed to successfully migrate up to BIM 360 software and operate effectively with its Revit counterparts. We'll cover lessons learned along the way and how we overcame obstacles to achieve quality work, improving speed and efficiency utilizing Civil 3D 2021 software, Desktop Connector, BIM 360, and a few talented individuals. Topics to be discussed include: 1) Creating 3D pipe networks that interoperate with Revit models in BIM 360 Model Coordination; 2) Using innovative workflows to create utility models with assumed depths; 3) Managing data shortcuts in the cloud to produce extremely clean models for clash detection; 4) Utilizing BIM 360 Document Management software to track and manage quality reviews; 5) Learning virtually with a team on a daily basis and demonstrating world-class communication skills; 6) Combining all geolocated models in Navisworks software with LIDAR files of downtown Toronto.
