KWR Karasek Wietrzyk Rechtsanwälte GmbH

Austria > Construction Tier 1

Thanks to its full-service construction and real estate law offering, KWR Karasek Wietrzyk Rechtsanwälte GmbH is a regular fixture on major construction, civil engineering and PPP projects across Austria, handling the entire lifecycle of such projects, including associated disputes. This broad offering is reflected in an equally broad client base including construction, real estate and project management companies as well as investors, architects and engineering consultants. Clemens Berlakovits, whose expertise extends to architectural law, is a key contact for the two last-mentioned client groups, while Paul Schmidinger is routinely involved in large-scale infrastructure projects and has recently also been advising on large-scale projects in the health and education sectors. Jan Philipp Schifko, who made partner in December 2020, is another key member of the team and has a focus on international projects. Name partner Georg Karasek handles the full range of contentious and non-contentious construction law.


Efficiency, friendliness, professionalism and accessibility.

Paul Schmidinger is super fast, competent and practice and solution-oriented.

Clemens Berlakovits impresses with his professional competence and his willingness to find solutions immediately. We have often had the experience with other lawyers that primarily point out the problems but no constructive proposal for a solution is made.’

For us, it was above all the competence in construction law and other areas of law, which are often involved. The broad spectrum of the firm covers all of this.’

Complex issues can be dealt with in a comprehensive and profound manner. The team is extremely solution-oriented and flexible and appointments can be made at relatively short notice if necessary.
