About us

Ability and trust form the foundation of every cooperation

Founded in 2005, KPPK Ziviltechniker GmbH has developed from a sole proprietorship called “Klaus Petraschka Planung & Konstruktion” to a company with more than 30 employees. Above all, however, KPPK stands for four values that distinguish us as a company:

We realize all facets of planning, construction and construction.
We are a competence center for a wide range of tasks.
We act flexibly – but always with the optimal solution in mind.
We rely on innovative ideas instead of patent recipes.


In cooperation with builders, architects and specialist engineers, we design all planning and testing processes in the construction industry. We offer you all the services you need to implement your construction project as easily and efficiently as possible. Again and again, we also break new ground and define the limits of what is feasible a bit further. We integrate our customers as partners right from the start – because this is the only way to create good buildings.

Climate-neutral construction, sustainable implementation

The future topic of the construction industry is renewable energies. We create viable concepts to equip buildings with climate-neutral and sustainable materials. Smart technologies such as solar power and air or geothermal energy have a positive effect on the environment. We advise you comprehensively and offer you tailor-made solutions in order to be able to integrate these innovations effectively and cost-efficiently – individually tailored to your special requirements and local conditions.

Together, reduce economically sustainable CO2

We cooperate as a program partner with klimaaktiv in the field of construction & renovation regarding the dissemination of the klimaaktiv building standard and a holistic view of the CO2 impact. The klimaaktiv building and renovation program is part of the BMK’s climate protection initiative klimaaktiv.

The building sector consumes more than a third of final energy, making it one of the largest emitting causes of carbon dioxide emissions. The saving of energy and materials, the use of renewable energy sources and renewable raw materials as well as the provision of a good indoor climate are becoming increasingly important.

How do we contribute to climate protection

For this purpose, R.O.S.E.® was created to compare alternative energy sources with conventional thermal energy sources. R.O.S.E.® can determine the exact amortization time at the beginning of a project based on the present value method.

Additional subsidies, energy price developments and interest rate developments are considered in order to make long-term statements. An additional feature allows the percentage of CO2 savings to be displayed based on characteristic values and to be considered in the calculation.

EMAS Eco-Management and Audit Scheme

Our goal is to continuously improve our environmental performance. For this reason, we have introduced the voluntary environmental management system EMAS (Eco-Management and Audit Scheme). EMAS is a field-tested instrument that helps, among other things, to implement national and European targets, to save resources and costs, to reduce environmental pollution and to continuously improve as a company. An essential part of the environmental management system is to involve and motivate employees so that they support the implementation of environmental measures. Together with our employees, we want to make a positive contribution to environmental protection and sustainability.
