Where the evidence doesn't reach
Every building carries uncertainty, and some of it is always hidden from whoever is reading. The switchboard sits behind its panel, the roof structure above the ceiling, the concrete cover inside the slab. This is the condition of reading any complex asset.
The register's job isn't to eliminate uncertainty. It is to price it honestly. Direct evidence produces a fixed cost. Partial evidence produces a range, set to the worst plausible outcome so the allowance releases rather than surprises. And where investigation itself is the right next step, the investigation is priced as its own provisional sum inside the row, with its own cost, horizon, and contribution to closing the gap.
This is how capital allocation already works everywhere else. Credit analysts, insurers, and portfolio managers all price uncertainty as a band with scenarios rather than a point estimate. The register does the same for the built environment.
And this is what unlocks analysis without physical inspection. A register that names what it can see, prices what it cannot, and commits to what would refine the range carries its position honestly. Inspection adds evidence and tightens the ranges, moving items from LOW to HIGH confidence. The discipline is the same either way.
Item 9.3 above is the shape of it. The Action leads with the $220,000–$420,000 range and names the refinement bridge. The Cost Basis derives the range from $18–$35/m² across the retail floor area, benchmarked against Q2 2026 contractor rates. The specialist audit that would close the gap sits on the short horizon as a $9,500 provisional sum in its own right. Nothing hides behind "to be confirmed".
