About us

Mélyépterv Komplex Close Corporation plays a leading role in the design of water utility network systems, related site-like facilities and flood protection systems. In addition, we perform a number of other civil engineering and utility design tasks for both public and private investors.

Our strengths are system-based design and complexity, which is reflected in the cooperation of several related disciplines throughout the construction process, from feasibility studies through engineering preparations (hydrogeology, geodesy, soil mechanics), permitting and construction planning to installation.

We use the accumulated knowledge and experience of more than 70 years in our activities. MÉLYÉPTERV KOMPLEX Llc was founded in 1992 by the employees of the Komplex Bureau II of the former state owned civil engineering company MÉLYÉPTERV (established in 1948). The new company was transformed to a Corporation in February 1995. We place great emphasis on continuous development and implementation of innovative and modern technologies. Thus, we became the market leaders in the design of the first mobile flood protection structures in Hungary.
