About meilenstein

In scheduling and process planning, the "milestone" marks fixed interim results and binding targets. The name says it all for us, because we accompany you step by step in the realization of your construction project. We support you with many years of experience, interdisciplinary expertise, and a high level of personal commitment. Despite all due care, the unexpected occasionally affects  the planning and construction process. With us as your partner, you save money, time, and effort because we not only know the problems, but above all the solutions.
