Subject: AI will not rescue bad project data
Preheader: The Friday briefing: why project records, not model choice, decide whether construction AI creates value.

The most expensive AI failure in construction may not be a hallucination. It may be a confident answer built on records the project already knew were incomplete.

Key bullets:
- $13tn: Global construction output in 2023, per McKinsey
- 10%: Global construction productivity gain from 2000 to 2022
- $1.848tn: Autodesk/FMI estimate for bad-data cost in 2020
- 30%: Firms saying more than half their data is bad

Main issue summary:
Construction AI is being sold as a model problem, but the practical constraint is whether project records are complete, current and usable enough to change decisions.

Why this matters for construction:
Project memory is where AI value becomes measurable. If a daily report mentions access delays on three consecutive shifts, the project should see a blocker trend. If a schedule update moves a milestone while field reports show missing materials, the review should connect those signals. If a photo record supports progress, it should tie to a location, work package and activity, not just a folder of images.
