    How AECOM is Revolutionizing Reality Capture

    Welcome to season 3 of the Confluence podcast! In this episode, AECOM’s Matthew Anderle joins Randall Stevens and Evan Troxel to break down how AECOM is pushing reality capture forward with custom-built robotics—rovers for “old dirty basements,” pipe crawlers for long culverts, and aquatic platforms for below-water inspections. They discuss layering environmental sensing on top of LiDAR point clouds, why digital twins must be operational (not just “great existing conditions models”), and what it means to help deliver LA28 as the first Olympics delivered in BIM. This episode is a tour through AECOM’s “mobile autonomous reality capture” toolkit, purpose built to extend scanning into places people can’t (or shouldn’t) go. They discuss: Why AECOM built a robotics program for reality capture: safety, access, and repeatability in harsh/confined environments“Sensorium” point clouds: humidity, temperature, air quality/particulates, and other context layered onto spatial dataHardware + workflow highlights: wireless FPV, safety tethers, modular payloads, off-the-shelf tool batteries, and custom electronicsThe “fiducial arm” problem: how to create registration targets inside smooth pipes so 500’ scans actually alignMakerspaces, trains, and hands-on fabrication as a pipeline for future STEM + AEC careersLA 2028: transforming ~60 venues on an immovable deadline, and what it means to run the program’s common data environment Links from the episodeAECOM: https://aecom.com/Matt Enderle on LinkedInLA28: https://la28.org/Digital twin (overview): https://en.wikipedia.org/wiki/Digital_twin ----- The Confluence podcast is a collaboration between TRXL and AVAIL, and is produced by TRXL Media.

    Unlocking Ancient Secrets with AI

    In the final episode of season 2 of the Confluence podcast, Brent Seales of University of Kentucky joins the show to talk about his groundbreaking work using AI and CT scanning to digitally unwrap ancient Herculaneum scrolls buried by Mount Vesuvius, making previously unreadable texts accessible. The conversation includes insights on collaboration with Nat Friedman, the Vesuvius Challenge, and the intersection of technology and humanities scholarship, along with Seales' new role directing an AI and Humanities Institute funded by Eric Schmidt's foundation.

About Brent Seales: Dr. W. Brent Seales is the Stanley and Karen Pigman Chair of Heritage Science and Professor of Computer Science at the University of Kentucky. He earned a Ph.D. in Computer Science at the University of Wisconsin-Madison and has held research positions at INRIA Sophia-Antipolis, UNC Chapel Hill, Google (Paris), and the Getty Conservation Institute. The Heritage Science research lab (EduceLab) founded by Seales at the University of Kentucky applies techniques in machine learning and data science to the digital restoration of damaged materials. The research program is funded by the National Science Foundation, the National Endowment for the Humanities, the Arts and Humanities Research Council of Great Britain, the Andrew W. Mellon Foundation, and Google. Seales is a co-founder of the Vesuvius Challenge, an international contest formed around the goal of the virtual unwrapping of Herculaneum scrolls. He continues to work with challenging, damaged material (Herculaneum Scrolls, Dead Sea Scrolls), with notable successes in the scroll from En-Gedi (Leviticus), the Morgan MS M.910 (The Acts of the Apostles), and PHerc.Paris.3 and 4 (Philodemus / Epicureanism). The recovery of readable text from still-unopened material has been hailed worldwide as an astonishing achievement fueled by open scholarship, interdisciplinary collaboration, and extraordinary leadership generosity. ----- The Confluence podcast is a collaboration between TRXL and AVAIL, and is produced by TRXL Media.

    Audacity, Antiquity, and AI

    In this episode of the Confluence Podcast, hosts Randall Stephens and Evan Troxel are joined by special guest Christy Chapman from the University of Kentucky to discuss how AI has unlocked antiquity. The discussion focuses on the origins of the Vesuvius Challenge, highlighting its key figure, Brent Seales, a research professor at the University of Kentucky. Christy, who works closely with Brent, shares insights about the ambitious goal to virtually unroll and read ancient scrolls carbonized by the eruption of Mount Vesuvius. Using advanced technology and AI, Christy explains the significant progress made, including the pivotal role of the open-source contest funded by Nat Friedman from GitHub. The conversation covers the technical and human aspects of the project, emphasizing the importance of clear communication, community involvement, and the relentless pursuit of seemingly impossible ideas. Later in the interview, the discussion around communication in technical projects has direct implications for both the Architecture, Engineering, and Construction (AEC) industry and software development teams. Just as the Vesuvius Challenge team had to bridge the gap between technical experts and conservators, AEC professionals and software developers must effectively communicate complex technical solutions to various stakeholders, from clients and product managers to contractors and end users. The emphasis on understanding stakeholder concerns, building trust, and creating clear communication channels is particularly relevant when implementing new technologies or methodologies in construction projects and software development cycles. The conversation highlights how successful innovation requires not just technical excellence, but also the ability to bring people along through empathy, clear explanation, and careful consideration of their perspectives and concerns.
