In this excellent video by Andy Fontana of Leica Geosystems he covers the 3 reasons architects should be using point clouds. If you are not designing based upon as-built drawings or models you’re designing in a vacuum. Unless you are building in a vacuum, this seems less than optimal…
Ragan-Smith recently competed field data capture of an alleyway near our office in Chattanooga, TN to assist with Passageways 2.0. Passageways 2.0 is a design competition to “enhance a new downtown alleyway in the heart of Downtown Chattanooga’s City Center”.
The competition is presented by River City Company, Cogent Studios, and Public Art Chattanooga as an opportunity to recreate an existing alleyway into a destination for pedestrians in downtown Chattanooga. Through an open RFP process, they sought “unique, innovative design concepts with a cohesive artistic vision from multi-disciplinary design teams”. Forty-five proposals were submitted representing 11 countries including the United States, Italy, France, Canada, Malaysia, India and China.
Three semi-finalists have been selected to further develop site specific designs to permanently activate the proposed alleyway and create a vibrant pedestrian corridor that is habitable and can be adapted for use as a small public event space. Ragan-Smith assisted by capturing the existing conditions with our Matterport Pro2 for site visualization and with our Leica C10 laser scanner to capture more accurate dimensions on the entire site. This data was then used to create a Building Information Model (BIM) of the site in Revit that was sent to the three semi-finalists to aid in the development of their construction plans.
A winning team and concept will be announced in Spring 2018 and installed Fall of 2018. Passageways 2.0 is made possible by generous grants from the Benwood and Lyndhurst Foundations. Keep up with the project and see the submissions on the Passageways 2.0 Website. You can visit the 3D Space yourself or view it through the video below.
The BIMForum announced the release of the latest Level of Detail (LOD) standards for Building Information Models (BIM) at the Fall Symposium which was held in Dallas, TX November 6-8. This year’s symposium was a group effort by the BIMForum, USIBD, And the Associated General Contractors of America. Additionally, new BIM implementation guides and Level of Accuracy (LOA) standards are also being prepared for release.

“3D Scanning has become commonplace on many projects, and can save hours of field verification. It can also add layers of complexity, confusion, and frustration if not executed properly on a project.” – Cool, a Point Cloud… Now What?
This article by Jordan Banning and Adam Muñoz for the Autodesk User Group International is an excellent primer on all of the issues that need to be understood or addressed in order to successfully implement a full scan to BIM project.
