Bavaria Tender Award-Winner Lookup (vergabe.bayern.de)

Purpose

Return a list of recently awarded public-procurement contracts on the Bavarian procurement platform vergabe.bayern — and, for each, the company that won the bid. The data comes from the platform's "Vergabeinformationen (ex-post)" section (post-award / ex-post notices published under § 20 Abs. 3 Nr. 3/4 VOB/A and § 30 Abs. 1 UVgO), which names the awarded company for each completed procurement. For every award you get the notice number + subject, the awarding authority (public client), the winning company, the procedure type, execution place, publication date, and a link to the official award-notice PDF. Read-only — never logs in, submits an offer, or clicks a bid button.

When to Use

  • Building a running list of companies that recently won public contracts in Bavaria ("who won lately").
  • Monitoring award activity of a specific awarding authority (e.g. a given Staatliches Bauamt) or watching who wins a category of work (Rohbau, Blitzschutz, Gerüstbau, Straßenbau, PV, …).
  • Competitive/market intelligence on public-sector construction & services awards.
  • Any flow that needs the winner of a tender rather than the open (not-yet-awarded) tender itself. For still-open tenders, use the "Auftragsbekanntmachungen" section instead (see gotchas).

Workflow

The public UI is a thin wrapper around RIB's meinauftrag portal. On www.vergabe.bayern.de the menu path Veröffentlichungen → "Vergabeinformationen (ex-post)" simply embeds an iframe whose src is:

https://meinauftrag.rib.de/public/InformationsFrame?filter=604283

filter=604283 scopes the frame to the Bavaria-wide ex-post (award) notices. This URL returns fully server-rendered HTML (~557 KB) — no JavaScript execution, no login, no cookie, and no anti-bot challenge. The fastest, cheapest, most reliable path is therefore a single HTTP GET and an HTML parse; scripted browsing is only a fallback.

Recommended: fetch + parse (1 request, no browser)

  1. Fetch the frame (residential proxy NOT required — a bare fetch returns HTTP 200): 
    browse cloud fetch "https://meinauftrag.rib.de/public/InformationsFrame?filter=604283"
  2. Parse each award block. The page renders ~20 most-recent awards. Per block, extract:
    • Notice title — the <strong>…</strong> (notice number + subject), e.g. 26-050680 Fassadensanierung WDVS.
    • Awarding authority — the muted line right under the title, e.g. Staatliches Bauamt Augsburg.
    • Awarded company (winner) — regex Awarded Company</div>\s*<div>([^<]+)</div> (label is English by default). This is the field the whole skill exists for.
    • Procedure type — Tender Procedures value, e.g. Öffentliche Ausschreibung (VOB/A) / Beschränkte Ausschreibung (VOB/A).
    • Project / execution place — the Project and Execution place values.
    • Award-notice PDF (when present) — href matching https://my.vergabe.bayern.de/remote/vergabeinformation.pdf.php?id=<N>.
    • Publication date — the day/month tile on the right (results are sorted by Publikationsdatum, descending, so the top of the list is the most recent).
  3. Emit the array of awards (see Expected Output). To take only "the latest N", just slice the top N — the list is already newest-first.

Optional narrowing

  • By awarding authority: each block has a "Show further assignments by …" link of the form /public/InformationsFrame/publisher/<base64(authority-name)>/filter/604283. Fetch that URL to get only that authority's awards. (The publisher segment is URL-safe Base64 of the authority display name.)
  • By keyword / location / radius: the frame has a search form ("Search term(s)" + "Search for awards", and "Show more search options" → sort, Where postcode/city, Area km radius, and registry toggles). For a keyword search you can drive the form in the browser path below; for bulk extraction the unfiltered fetch + client-side filtering is simpler.

Browser fallback

Validated in a bare Browserbase session (no --verified, no --proxies):

  1. browse open "https://meinauftrag.rib.de/public/InformationsFrame?filter=604283" --remote
  2. browse wait load then wait ~1 s.
  3. browse snapshot — the accessibility tree already exposes, per list item, the title (strong), the authority, an AWARDED COMPANY static-text node, the publication date, and (when present) the FORMS PDF link. The winner is in the collapsed summary — do not click each row.
  4. Read the winners straight from the snapshot. Only if you also need Tender Procedures / Execution place / Client data per row, expand a row (far-right ▼ caret) or, better, fall back to the fetch+parse path which already contains those fields.

Site-Specific Gotchas

  • Ex-post = awarded; Auftragsbekanntmachungen = still open. "Vergabeinformationen (ex-post)" (InformationsFrame?filter=604283) is the ONLY section that names a winner. The "Auftragsbekanntmachungen" section lists open tenders (no winner yet). If the ask is "who won", always use the ex-post frame; do not confuse it with the tender-notice list.
  • The real data lives on meinauftrag.rib.de, not on vergabe.bayern.de. The .bayern.de page is just site chrome + an iframe. Fetching the .bayern.de HTML alone yields a cookie banner and an empty shell — you must go to the InformationsFrame URL to get the awards.
  • No anti-bot, no auth, no proxy needed. Pre-run probe reported no anti-bot; a bare browse cloud fetch (no --proxies) and a bare remote browser session both returned HTTP 200 with the full 557 KB payload. Do not waste a residential-proxy/--verified session on this.
  • Labels default to English on the fetch/API surface. The InformationsFrame returns Awarded Company, Tender Procedures, Execution place, Client data (English) even though the public site chrome is German. Parse against the English labels; the German equivalent would be Auftragnehmer / Vergabeverfahren if a locale flip ever occurs.
  • ~20 awards per load, newest first. The frame renders roughly the 20 most-recent awards sorted by Publikationsdatum descending. That is usually plenty for "lately". There is no obvious offset/page param on the public frame; narrow by publisher (Base64 publisher path) or by the search form (postcode/radius/keyword) to reach older or more specific awards.
  • filter=604283 is the Bavaria-wide client set. The "Show more search options" panel also lets you toggle other registries (Vergabeplattform Berlin/Stuttgart/Wuppertal/Hannover, GMSH, RIB eVergabe) — leaving the default gives all Bavarian public clients (Staatliche Bauämter, Landratsämter, Städte/Gemeinden, Zweckverbände, etc.).
  • The "•••" menu ≠ the detail expander. The three-dots control opens "Show further assignments by <authority>" (a per-publisher filter). The far-right grey ▼ caret expands the per-notice detail block. Neither is needed to read the winner (it is already in the summary).
  • Award PDFs. Detail PDFs are https://my.vergabe.bayern.de/remote/vergabeinformation.pdf.php?id=<N> (form "341 Information über eine Beauftragung"). Only some list items surface the PDF link in the summary; the rest expose it inside the expanded detail block.
  • Some "companies" are sole traders / place-tagged strings. Awarded-company values are free text as entered by the authority — you'll see clean GmbHs (STRABAG AG, Heinrich Schmid GmbH & Co. KG), bare person names (Stefan Kraus), and name+postcode blobs (STL-Bau, 95466 Weidenberg). Treat the field as an opaque display string; don't assume a legal-form suffix.
  • Inner-agent output cap (browser path only). The autobrowse harness caps model output at 4096 tokens; emitting all 20 awards as full objects truncates the JSON. On the browser path, cap at ~10 awards or emit compact rows — or just use the fetch path, which has no such limit.
