Smart Twins

In this episode of Smart Twins, host Jimmy Abualdenien is joined by Bart Brink, leader of the national renovation program for assets in infrastructure, housing and real estate in the Netherlands, and chair of the digital twin working group at buildingSMART International. Bart brings deep insight to their conversation as a national and global leader in the digital twin environment since 2017. Bart shares how he first encountered the world of digital twins and became passionate about better connecting the physical and digital worlds. From building bridges to planning cities, Bart sees the potential behind digital twins and is personally committed to driving the creation and optimizing of dynamic virtual representations of physical  assets. Bart takes a step back and explains for listeners the essential definition of digital twins, and explores how that definition has evolved over time. Bart and Jimmy discuss the importance of a dynamic flow of information between the digital twin and the real life asset, and the value of looking beyond a single digital twin to create an ecosystem of digital twins. They also explore the critical consideration of how to safeguard data used to create a digital twin, taking into consideration how the owner maintains financial, operational and legal control of their data. Bart also emphasizes the importance of digital twins beyond just a replica or virtual representation. He lays out how digital twins can provide key insight for decision makers, and provide value creation by providing business insights. He stresses that the value of a digital twin is not just in analyzing data but in providing data for human interpretation to improve decision making. And he points out the value of digital twins beyond the individual, exploring the importance of governments creating an ecosystem that promotes a collective effort and communal reward from digital twins. Bart wraps up the conversation exploring how artificial intelligence can be paired with digital twins – to reinforce their productivity and make them even more accessible – and provides insight for those looking to pursue a digital twin. 

In this episode of Smart Twins, host Jimmy Abualdenien speaks with Maximillian Weiß, Head of BIM and Digital Construction at Deutsche Bahn, about the second core route project in Munich. Weiß leads the BIM GAS team responsible for this megaproject, which aims to ease the pressure on Munich's public transport system by building a 7-kilometer tunnel with three new stations.Weiß shares his journey from studying geology at the Technical University of Munich (TUM) to working on major construction projects, including roads, bridges, and train stations. He discusses how his early work in critical foundation construction shaped his shift toward digitalization, specifically how Building Information Modeling (BIM) can improve workflows and solve complex construction challenges. Weiß explains how BIM was first introduced to him in 2016 and describes its use in the design and planning stages of the second core route project.The conversation dives deep into the challenges of building beneath Munich's central station, maintaining ongoing train operations while constructing new infrastructure. Weiß also shares insights into using point clouds and LiDAR to digitize existing assets, combining 2D drawings with 3D models to improve accuracy.Listeners will hear about the significance of simulations in ensuring safety and optimizing passenger flow in new train stations, as well as the use of BIM in both the design and construction phases to keep the project on track. Weiß also touches on future uses of AI and digital twins in construction, offering a glimpse into how Deutsche Bahn is working to stay at the forefront of technological innovation.

In this episode of Smart Twins, Jimmy Abualdenien is joined by Dr. Alex Braun, Senior Vice President for Digital Transformation and CIO at the Technical University of Munich (TUM). Together, they explore the evolving landscape of digital technologies in construction and facility management.Dr. Braun shares his journey from studying civil engineering to specializing in construction informatics, detailing his pioneering work in construction progress monitoring using drones and photogrammetry. He highlights the challenges and advancements in data collection methods over the years, emphasizing how technology has dramatically improved the ability to assess construction sites.Listeners will gain insights into Dr. Braun's innovative approach to construction progress tracking, which combines Building Information Modeling (BIM) with drone-captured imagery and AI-powered detection methods. He elaborates on the concept of digital twins in construction and facility management, offering his perspective on their definition and applications.The conversation shifts to Dr. Braun's current role at TUM, where he oversees digital transformation for a university with 52,000 students and 12,000 employees. He details the challenges of managing IT infrastructure for such a large institution and discusses ongoing projects to digitize and create 3D models of TUM's extensive campus facilities.Dr. Braun also touches on TUM's sustainability strategy, focusing on efforts to assess and improve energy efficiency across more than 450 buildings. He emphasizes the importance of data aggregation and visualization in understanding and optimizing facility performance.Throughout the episode, Dr. Braun stresses the significance of embracing digital transformation, even through small initial steps. He advises organizations to start by assessing their current assets and data as a foundation for improvement, highlighting the "80-20" approach to project implementation.This episode offers valuable insights into the practical applications of digital technologies in large-scale facility management and the challenges of implementing digital transformation in complex organizations. It's a must-listen for professionals interested in the future of smart buildings, digital twins, and sustainable facility management.

In this episode of Smart Twins, Jimmy Abualdenien is joined by Fernanda Leite, the Associate Dean for Research at the Cockrell School of Engineering at the University of Texas at Austin. Together, they delve into the transformative concepts of BIM and digital twins within the architecture, engineering, construction, and operations industries.Fernanda shares her fascinating journey from childhood inspiration to her pioneering work in Building Information Modeling (BIM), highlighting impactful research that compares 2D and 3D design coordination and the evolution of BIM in the construction industry.She details how visualization in design can uncover critical errors and the significant role of virtual reality applications in construction, underscoring the necessity for strategic and purposeful technology implementation.Listeners will gain insights into her current role overseeing 300 faculty, 6,000 students, and multiple research centers, as well as her leadership in four ongoing capital projects. Fernanda elaborates on her cutting-edge work to minimize construction waste through a circular economy mindset and highlights the rapidly advancing role of scan-to-BIM technologies to facilitate efficient facility management.Throughout the episode, Fernanda emphasizes the importance of incorporating real-world considerations into digital construction practices. This episode is a deep dive into the future of smart buildings, BIM, digital twins, and AI, revealing how these innovations can enhance asset performance, reduce costs, and improve safety in construction and beyond.
