This white paper synthesizes insights from the interactive roundtable discussions held at Building Transformations’ 2025 Flagship Summit in Toronto, Ontario, Canada, where industry leaders, practitioners, and stakeholders from across North America explored critical challenges in digital adoption. Organized around the themes of data interoperability and standards, common data environment fragmentation, and digital twin and lifecycle data, the discussions highlighted what’s working, persistent barriers, and actionable strategies to advance the architecture, engineering, and construction (AEC) industry. Key takeaways include the importance of open standards for seamless data exchange, maintaining a flexible single source of truth, implementing owner-driven processes to ensure data flows effectively from design through operations, and leveraging emerging AI opportunities. By addressing these challenges, the industry can enhance collaboration, reduce fragmentation, and unlock the full potential of digital technologies across the project lifecycle.
