Nach 20 Jahren hatte die alte Traglufthalle des HTCB ausgedient. Wir suchten deshalb eine neue Halle für die drei Tennisplätze (36m x 54m). Nach einer intensiven Evaluation entschieden wir uns für eine Traglufthalle der Firma DUOL aus Slowenien. 

Die Vorteile gegenüber der alten Halle waren: Heller, besser isoliert, weniger Energie verbrauchend. Trotz der geografischen Distanz waren die Verhandlungen stets sachlich, fair und zielführend. Der Transport klappte tadellos. Die erste Installation wurde zusammen mit DUOLMitarbeitern und Klubmitgliedern durchgeführt.

Die Klubmitglieder sind sehr zufrieden mit der neuen Halle und freuen sich darauf, nächsten Winter wieder in der Halle spielen zu können.

We are very much delighted to extend our heartfelt gratitude to DUOL d.o.o. for the successful completion of the installation of the DUOL Air Dome at our Global Sport Park in Al Khobar, Kingdom of Saudi Arabia.

This has been a dream project for all of us at Global Sport Gate and we were able to complete it well within the schedule due to the untiring commitment and efforts of everyone involved, especially the two energetic Engineers from DUOL, Mr.Leon Skof and Borut Staresinic.

All of us at Global Sport Gate were very much amazed at the high level of professionalism and dedication displayed by both Mr.Leon and Mr.Borut.

As for the DUOL Air Dome itself, we are more than happy and satisfied with the very high quality of every component of the Air Dome which makes it a very unique product by itself.  Also, since this being the very first of its kind in the Kingdom of Saudi Arabia, we have no doubt whatsoever that this Air Dome will serve to convince all our prospective customers to procure their DUOL Air Dome from us soon without any hesitation.

Moreover, since its installation, our DUOL Air Dome has become a site of attraction and talk of the town as well. This in itself is a tribute to the concept as well as the very high quality of the structure.

Wir nutzen die Halle nun seit Anfang Oktober 2018 und sind sehr zufrieden. Die Entscheidung die Sanierung mit DUOL auszuführen hat sich als goldrichtig herausgestellt. Die Betreuung durch DUOL während der Sanierungsphase war vorbildlich. Das vorgefertigte Hallendach passte einwandfrei auf die vorhandene, renovierte Konstruktion. Das Montageteam ist außergewöhnlich qualifiziert und hat das Dach einwandfrei montiert.

Insgesamt war der Sanierungsablauf und auch die Schnittstellenkommunikation mit anderen an der Sanierung beteiligten Unternehmen für uns unproblematisch. DUOL hat mit allen Unternehmen sehr gut kommuniziert und hat dadurch einen großen Anteil am reibungslosen Ablauf der Sanierungsmaßnahmen.

Für unseren Verein ist eine solche Maßnahme nicht alltäglich und gehört auch nicht zu den Kernkompetenzen eines Tennisclubs. Die Zusammenarbeit mit DUOL hat uns sehr geholfen und das Projekt ist erfolgreich abgeschlossen.

Wir möchten uns bei DUOL für die korrekte und einwandfreie Abwicklung der Hallensanierung bedanken.

Besonders bemerkenswert ist, die Tatsache, dass mit Abschluss der Arbeiten der Kontakt zu DUOL nicht abgebrochen ist.

Wir stellen unsere Halle gerne als Referenzobjekt zur Verfügung. Die Halle ist in Kombination von Dach und Hallenboden einmalig in Nordrhein – Westfalen.

Wir können DUOL uneingeschränkt weiterempfehlen.
