About us
Who We Are
Since its founding in 2005, KPPK Ziviltechniker GmbH has grown from a one-person business into a renowned civil engineering office. With our comprehensive technical solution expertise, we offer a broad, interdisciplinary range of services and fully identify with every project we are entrusted with. Our clear focus is on quality, sustainability, and resource conservation. Our mission is to create optimal and enduring value for our clients and for the society in each of our projects.

Our Values: Responsibility, Sustainability, Innovation
As a klimaaktiv program partner and an EMAS-validated company, we take our social responsibility very seriously. In line with the three pillars of sustainability – economy, ecology, and social responsibility – we are actively committed to a climate-neutral future. With our in-house developed tools R.O.S.E.® and REACT®, we support resource-efficient construction projects and take significant steps toward reducing CO₂ emissions.

Securing the Future Through Innovation and Cooperation
We promote collaboration at eye level, respectful interaction, and the personal as well as professional development of all our employees. Through targeted advanced training, exciting projects, and a motivating environment, we create space for ideas and individual growth. Our award with the BGF seal of quality confirms our commitment to a healthy and respectful corporate culture.

Our Goal: Growing Together and Shaping a Sustainable Future
With a clear vision and high-quality standards, we are already developing solutions today for the challenges of tomorrow. Our work is characterized by innovative strength, open communication, and a deep awareness of environmental and climate protection. Cooperation with our clients is always at the core of our work – together, we realize projects that are ecologically, economically, and socially sustainable.
We build for future generations
Let’s plan together.
