The Aperlena Verdict

Open race

No supplier dominates: 39 different companies have won the last 41 comparable contracts from this buyer over 5 years. This is a genuinely open race.

Based on 41 comparable awards by this buyer in this sector over 5 years. Every verdict is recorded before the outcome and graded against the award notice. How we score ourselves.

Summary

Machine-generated summary

The buyer is renovating the low-voltage main distribution board (NSHV) located in the transformer station next to the existing school building at Auf der Klappe in Duderstadt, which serves the Eichsfeld-Gymnasium and Heinz-Sielmann-Realschule and will be extended to house the Pestalozzischule. The outdated switchboard, fed by two 400 kVA transformers (one owned by energy supplier EEW, one by the district), must be replaced and sized for a possible upgrade to 630 kVA each. Renewal work is planned for the Easter and summer holidays 2027, with preparatory work possible earlier after coordination.

Description

Das Bestandsgebäude der zwei Duderstädter Schulen Eichsfeld-Gymnasium und Heinz-Sielmann-Realschule, das sich am Standort Auf der Klappe befindet, soll um einen Neubau erweitert werden, der auch die Pestalozzischule Duderstadt aufnehmen soll. Neben dem Gebäude befindet sich die Trafostation, in der sowohl die Mittelspannungsschaltanlage als auch zwei Transformatoren mit jeweils 400 kVA Leistung untergebracht sind. Einer ist im Eigentum des Energieversorgers EEW, der andere ist im Besitz des Landkreises. Die Erneuerung der NSHV-Teile ist in den Osterferien 2027 und den Sommerferien 2027 vorgesehen, vorbereitende Arbeiten können nach Abstimmung mit der Schule und der Bauleitung außerhalb der Ferien erfolgen. In der Trafostation ist die Niederspannungs-hauptverteilung (NSHV) installiert, die anteilig dem Energieversorger EEW sowie dem Landkreis zugeordnet ist. Die vorhandene NSHV ist veraltet, weist technisch abgängigen Zustand auf und entspricht nicht mehr dem aktuellen Stand der Technik. Aufgrund dessen und der Tatsache, dass sie sich nicht für den Neubau erweitern lässt, muss diese erneuert werden. Die NSHV wird von zwei Transformatoren mit jeweils 400 kVA, 577,8 A eingespeist. Für eine mögliche Erhöhung der Transformatorenleistung auf jeweils 630 kVA soll die neue NSHV entsprechend höher ausgelegt werden. Sie besteht wieder aus dem Teil EEW und dem Teil Landkreis, die Leistungsschalter der Einspeisung sind im Teil EEW angeordnet. Die Breite der einzelnen Schaltgerätekombinationen (Reihenschaltschränke) passt nicht mehr zu den Abständen der vorhandenen Auflageschienen. Um einen sicheren Stand zu gewährleisten, sol- len an der Vorder- und Rückkante der Schränke Flacheisen auf der bestehenden Tragkonstruktion montiert werden.
