“What if the biggest risk to our infrastructure isn’t corrosion, cracking, or ageing, but the assumptions we still make?”

Most asset inspections rely on “representative sampling”, checking a handful of areas and extrapolating the rest. But in complex, ageing buildings, that approach can quietly hide defects, increase risk, and lead to expensive surprises later.

In this episode of the Structural Intelligence Podcast, host Owen Keenan sits down with Derek Feebrey, Co-Founder and CEO of Trendspek, to explore why sampling often falls short, and what a better future looks like, one built on complete, auditable data.

From aviation-inspired precision to millimetre-accurate 3D digital records, Derek explains how the industry is shifting from static PDF reports to living models of the built environment, and why the biggest barrier is not technology, it’s trust, process, and change management.

If you work in engineering, asset management, facilities, or infrastructure, this episode will challenge the way you think about inspections, evidence, and decision-making.

🔑 Key Takeaways:

• Why “representative” inspections can miss critical risks
• How complete data reduces assumptions and improves decisions
• Why 3D modelling is changing how we plan remediation and budgets
• The role of engineers, contractors, and owners in better collaboration
• Why adoption is more about people and process than technology
