It's July and here at 'the desk', that means we are preparing for Autodesk University. Even if you haven't started to think about it, I'm getting really excited about what I saw submitted for class topics this year and for what I think will be a great set of sessions for the Infrastructure Symposium.
So, even though I can't reveal what's happening yet, I wanted to share some cool examples from AU2013 around capturing data and creating models to help with better understanding existing conditions. Over the next few weeks, I'll be sharing these cool technology examples around data capture, 3D modeling, visualization in a series called See it. Model it. Here's the first great example!
Kevin Gilson, Design Visualization Manager at Parsons Brinckerhoff, participated in a panel discussion at the Infrastructure Symposium. Kevin spoke about projects where they are using Autodesk InfraWorks in combination with Civil 3D, ReCAP, 3ds Max and more to support the design environment. In his example, Kevin shows using InfraWorks for visualization to improve stakeholder communication and for internal project communication and proposal development. He demonstrated the capture of an existing overpass bridge to improve their knowledge of existing conditions for designing the roadway. Then, he created an interchange model in InfraWorks, and with ReCAP scanned data for the overpass including:
- Geospatial data: USGS aerials, terrain data; and San Mataeo County Street Centerlines
- Civil 3D Roadway Designs: Existing as-builts and alternative designs
- 3D Model data: trees, vehicles
In order to build alternatives for the new intercahnge they had to better understand the existing overpass to support design decisions. Kevn said they captured existing structures and features with survey controlled LiDAR scanners. See the accurate 3D point cloud of the 101 bridge in this video.
- It only took a half day to scan, and by doing ground-based capture, they were able to get a very accurate view of this overpass.
- ReCap helped them assemble the images and go in and remove some of the artifacts of traffic at the busy intersection; once the scan was cleared of artifacts, they exported it into InfraWorks.
- The model of the bridge is to scale, highly accurate in project coordinates. With this, they could move around the model interactively and measure features within the point cloud accurately.
So, Kevin's was a great example of how to capture the existing conditions to make better decisions. And now, with Autodesk Bridge Design for InfraWorks 360, a vertical solution that works with InfraWorks 360, you could take this a step further by doing some of your preliminary design work while you are in InfraWorks 360.
