Every construction project generates thousands of documents, drawings, decisions, and specifications. Then the project ends — and most of that intelligence disappears, buried on USB sticks or lost in SharePoint folders nobody revisits. In this episode, hosts David and Rob sit down with Jon Sinclair of Performance Building Technologies to explore why the construction industry's data problem is costing New Zealand dearly, and what businesses of any size can do about it today. Jon's path is anything but conventional — environmental scientist turned London developer turned managed services specialist — and it gives him a sharp eye for where the industry is leaving value on the table. His solution is something he calls "asset memory": a shared, searchable intelligence that carries the story of a building long after the project team has moved on.  What You'll Learn The scale of the problem. Construction professionals spend roughly 35% of their time on non-value-added work. A 3,500-page specification that takes 3–4 weeks to manually review can be processed by AI in under two hours — more accurately. New Zealand's productivity gap is stark: it costs us 50% more to build infrastructure than the US, and up to 900% more than countries like South Korea and Finland. The handover cliff. The biggest performance loss in construction doesn't happen during a project — it happens the moment it ends. Operational teams inherit a curated subset of project data; the rest vanishes. Jon makes the case that handover should be treated as a critical project phase, not a loose end. Why you're building two assets. Every project creates a physical asset and a digital one. The physical asset is visible; the digital one is usually ignored. But the digital asset compounds in value over time — informing maintenance, resolving disputes, proving compliance, and affecting resale. Jon shares a real example where a commercial owner discovered their building was 20% larger than they'd been leasing it for, simply because no one had ever checked. What asset memory looks like in practice. Rather than curating a subset of information into a structured system, Performance Building Technologies captures everything and lets AI do the filtering. Their approach layers a small language model trained on New Zealand building codes and construction terminology on top of all project data — so facility managers can ask "What's behind the wall in Ward 3?" or "What are the warranty conditions on the specialist lighting?" and get answers in seconds. The rework revelation. 70% of health and safety incidents on construction sites happen during rework. When teams are under pressure to redo work, that's when accidents occur. Solving the data problem is a safety issue as much as a productivity one. Practical first steps. Jon's three starting points for any construction business: (1) build a visual record of your work on site — LiDAR-equipped phones and apps like Polycam make it simple; (2) use AI to understand the specs you're signing before you sign them; (3) think about how you hand over information, because retained payments are often tied to digital deliverables. Key TakeawaysThe organisations that treat data as an asset — not an afterthought — will be the ones that close New Zealand's productivity gap and set a new benchmark for the industry. Start small, capture everything, and remember: the digital foundation matters just as much as the physical one.Connect with Jon Sinclair and Performance Building Technologies to learn more about asset memory and digital transformation in construction.Rapid Fire Questions
