The regulations of 283 municipal master plans (PDM) in force, the 278 of mainland Portugal and 5 in the Azores, in one machine-readable model: consolidated text with the published notices, a stable identifier per article, paragraph and point, the zones of the land-use map and, for 90 plans, rules with quotations. How it was built, how it was checked and what still fails.

If Portugal builds more homes a year, how much do prices fall? A calculator with the whole sum in sight, on the elasticity measured across Portuguese municipalities (Ribeiro, Vilares and Carvalho, 2025), and the comparison with short-term rentals and foreign demand.

About 300 thousand homes are missing and 723 thousand stand empty, but only part of them is habitable and where there is demand. The numbers checked in the official sources, what happened between 2023 and 2026, what other countries did and what it cost them, what helps those who earn less, and a ten-year plan with targets and costs. 15 charts, all sources.

From the Constitution to the municipal regulation: the 13 branches that govern what gets built in Portugal, as a linear tree, with the status of each legal instrument confirmed in the Diário da República — and an interactive timeline: drag the slider from 1951 to 2026 and the tree reacts, including what changes on 1 October with the new RJUE. With an unprecedented cross-check: which regulation is cited by each unit of works.

How aerospace, the car industry, semiconductors, logistics and cinema integrated their chains — open standard, someone with the contractual power to impose it, a product that repeats — and the test construction fails: no building in the world has its process documented and its as-built model publicly accessible. The closest cases, why FM models stay closed (it is not the vendors), and what can be mirrored without turning the site into a factory.

Marketing promises millimetre laser surveys; the studies that validate point clouds and BIM models against independent measurements find centimetres — and the standards themselves (USIBD LOA) specify in bands of 15–50 mm. Where the millimetre is real, where it is nothing but a datasheet, and what to demand in tender documents instead of the word millimetric.

Where the discount is large, it is the land, the profit and the scale that get cut — not only the tag.

What a permitting case is when it is, seriously, digital: in Estonia, every document belongs to a numbered procedure with a published authority, manager, status and duration — hanging off a public building down to the geometry.

Directive (EU) 2024/1275 (EPBD) defines it — but does not make it mandatory ("caso exista", "should it exist"). It is Portugal's 2030 BIM mandate that will populate it by law.

The 100–500 scale is a good common language and a bad contract clause: one number per element does not say for what use, is not validated by machine and has no place for documentation. What EN 17412-1 puts in its place — and the Portuguese advantage of arriving late.
