Awards and Certifications


DELTA is a family-friendly employer “berufundfamilie” 2023/24 and has also been recertified as a leading company in Austria in 2024.

The “Elisabethinen Wien-Mitte” project was awarded the Monument Protection Medal of the Republic of Austria at the end of 2023. The Monument Protection Medal was also awarded – in the spirit of the diversity and variety of existing monuments – for projects that are particularly sustainable, innovative or exemplary in terms of climate protection and contribute to preserving buildings in line with their listed status and making them climate-friendly. Over a construction period of eight years, the old Elisabethines’ building in Vienna was carefully renovated with the support of the Federal Monuments Office and modern extensions were built. Old and new are now harmoniously combined architecturally.

The Takeda Innovation Capability Center (ICC) in Bratislava, for which DELTA Slovakia was commissioned with the interior design, BIM and architecture from the perspective of a local architect in collaboration with JACOBS Architekten, was officially awarded the “Innovative Office of the Year” award in 2023. This unique design is based on the idea of a mini-city oriented towards future forms of work, taking a hybrid approach that combines historical spaces, innovative technologies, Japanese culture and biophilic design in a healthy, collaborative and highly human-centered office space.

In 2018, DELTA won the Lower Austrian Timber Construction Award for the IFA Tulln laboratory and office building and the KOOP Award as a particularly cooperative project manager in the “Smart Campus” project, as well as many other prizes. The planning of the projects “BOKU Neubau an der Türkenschanze” and the “Schichtgründe” residential complex in Vienna were awarded “klimaaktiv” (which means climate active) certificates in February 2019.

DELTA is the initiator of “IG Lebenszyklus Bau”, which provides a platform on which large and small companies and experts can network to work together on promising topics relating to the life cycle of real estate. As a klima:aktiv partner and member of ÖGNI, DHK and many more, DELTA is committed to greater sustainability, digitalization and partnership in the construction industry.
