Die Krone von Vancouver – Erneuerung des BC Place Stadions
Bibliographic record
Abstract
Abstract Das BC Place Stadion liegt im Herzen von Vancouver, perfekt in das Nordufer des False Creek eingebettet. Das Stadion mit Kapazitäten für 60.000 Zuschauer wurde 1983 eröffnet und war bis zum Abbau des Daches die größte luftgetragene Sporthalle der Welt. Mit zunehmender Nutzungszeit ergaben sich aus dem komplett unter Innendruck stehenden Stadion massive betriebliche Einschränkungen. Luftschleusen für die Zuschauer und auch für die Zugänge in den Innenraum erschwerten die Entleerung des Stadions im Evakuierungsfall. Die hohen Energieaufwendungen für die Gebläse und die Abtauanlage sind heute nicht mehr vermittelbar und erwiesen sich zudem als betriebswirtschaftliches Problem. Zusätzlich wünschte sich einer der beiden Hauptnutzer, die Fußball spielenden Vancouver Whitecaps, Spiele unter freiem Himmel austragen zu können. Desweiteren sollte das gesamte Stadion renoviert und – auch in Bezug auf die sehr hohe Erdbebenbeanspruchung – auf den neuesten sicherheitstechnischen Stand gebracht werden. Mit dem neuen Entwurf wurde eine sehr komplexe Aufgabenstellung bewältigt: Eine moderne Dachkonstruktion mit wandelbarem Innendach wurde auf eine existierende Stahlbetonkonstruktion aufgesetzt. The crown of Vancouver – Revitalisation of the BC Place Stadium. The BC Place Stadium is situated in the city centre of Vancouver directly next to False Creek. The old stadium, with a capacity for 60,000 people, was opened in 1983 until its demolition. It was the world’s largest air dome. With time, massive operational constraints appeared due to the fully inflated inner space of the air dome. Emergency evacuation of the stadium was complicated due to required air locks on spectator and access routes. The high energy consumption for the inflation units and the snow melting system were not practical anymore and were an economical problem for the user. In addition one of the two main users, the Vancouver Whitecaps, always wanted to have the possibility to play open air. Furthermore, the complete stadium complex had to be renovated and – with regard to the massive seismic demands on the structure – updated to the state of the art. With the new design a very complex task has been solved: A state of the art roof structure with a retractable inner roof was added onto an existing concrete bowl structure.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
