What the atelier investigates and publishes: documentary studies on primary sources, radars of the free scientific literature and calculation tools that run in the browser. Every page declares its sources, its method and its verification date in the footer; the index below groups them by type.
Counts over the free scientific literature (OpenAlex): what gets published, on which topics, at what pace, with every paper linked to its full text. Topic classification is automatic, by a dictionary of expressions over title, abstract and keywords: it measures trends and does not replace a systematic review.
10,800+ open access BIM papers since 2015, classified into 27 topics. Click a cell on the map and open the papers of that topic and year. Trending: digital twins, IoT, ISO 19650, 5D.
4,300+ papers on reality capture applied to the built environment. Gaussian splatting went from zero to 200 papers/year in three years; photogrammetry jumped 50% in 2025.
345 thousand papers to answer one question: have the two fields moved closer or drifted apart? A verdict measured year by year, the shared ground, and the role of BIM in each field.
Documentary work on primary sources: legislation, official reports, standards, databases and competition briefs read in full. Every claim cites document and page; the verification date is in the footer of each study.
A documentary archaeology from 1940 to 2026: from the state fee rule (RCHAP/ICHPOP) to the European prohibition of fee tables, down to the OA reports that measure design awarded at 2.54% of the works value.
The perfect tender documents and the perfect response, distilled from 705 architecture competitions (2010–2026) and 1,059 documents read in full — price measured where it is a criterion and where it is not, the most tested jury scheme, and the formal exclusions that cost proposals.
How six public clients — Germany, Spain, the Basque Country, Norway, Sweden and the Netherlands — turn BIM into a procurement requirement. Three generations of maturity, from text in the tender documents to the machine-readable requirement.
The national BIM strategy (RCM 89/2026) graded against the eight macro maturity components of Succar & Kassem, on the BIMMI scale. Facts verified against the public sources, with the trigger that would raise each grade.
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 economics of the Commission study, the French, Flemish and Estonian models, and the map of who awards the most works in Portugal, built on the open data of the Portal BASE.
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.
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. And a tour of the world with real samples of each dataset, checked against the requirements of the EPBD logbook: every country has opened one layer — nobody has yet the complete logbook the law asks for.
ESPR (EU) 2024/1781 and the family of laws around it: chronology to 2030, the EN standards of JTC 24, the EU registry already operational — and the 893 papers published on the topic, filterable.
ICE × KBOB × ÖKOBAUDAT (the three free databases), side by side, per kg, modules A1–A3: the same manufacturing route converges (−6% on EAF steel); different routes diverge 2.4× within the same database. Methodology, assumptions and replicable scripts.
A group debate on rents, empty homes and taxes on land, turned into a literature review: 1,641 papers collected, 33 studies extracted, cases from four continents — every claim with its source. Rent control, upzoning, vouchers, land value tax and Vienna, with the final question: can rents come down without destroying the market?
The "20% below market" promise of the MOME cooperatives (Gaia and Porto), measured for the first time against real listings — and set beside what the studies from other countries measure: Vienna −25%, Zurich −36%, Barcelona −45%, Uruguay −38%, US −51%. Where the discount is large, it is the land, the profit and the scale that get cut — not only the tag.
Eleven sources that the answer engines (ChatGPT, Claude, Gemini, Perplexity, Copilot) read for construction questions in Portugal, audited on five retrieval signals: Common Crawl, llms.txt, robots.txt, sitemap and structured data. Round 0: ten of the eleven are in the corpus — and the only one missing has the best-kept door of them all.
Local calculation in the browser, no server and no upload, over public tables and rules reproduced with the source in sight.
For a works value, what the Portuguese State paid for design (OA Reports 2024-25) alongside four benchmarks with public text: ICHPOP 1972, the German HOAI (§ 35), the Italian parameters decree and the Spanish fee schedule the OA used as "Spain". Every line with source, calculation base and limits of comparability.
Upload an IFC and see how far your product data are from what the passport will require: identifiers, manufacturer, properties, classification, environmental. The file does not leave the browser.
The Pr-Products codes of the Portuguese SECClasS classification (V2.0) for tiles, paints, doors, sanitary ware, ironmongery, boards and blankets, with the designation verified against Uniclass 2015 — the source's Portuguese column has translation errors, corrected or flagged here — and a stable identifier in bSDD.
Argued positions and curated lists, with the evidence linked.
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.
International architecture competitions open with a €0 entry, each one confirmed on its official page — ideas, real works and exhibitions, filterable by deadline, type and audience. The platforms that live on entry fees stay out, with the fees measured and the source in sight.
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.
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.
