Digital twins are transforming how towers are designed, managed and marketed. By creating accurate virtual models of sites, owners can verify structural capacity, plan equipment changes, speed up tenant applications and reduce costly site visits. This session explores the journey from initial capture using drones, LiDAR and photogrammetry to fully integrated twins that support predictive maintenance and automated engineering. Speakers will share real-world results, discuss data accuracy and standards, and address the business case for portfolio-wide adoption. Attendees will learn how digital twins are becoming a core operational tool rather than a one-off inspection deliverable.
