History

From our past to our present, our history reflects a journey of innovation, growth, and leadership — driven by the people behind our success.

Building Our Legacy

Vojtech Gall and Kurt Zeidler established GZ Consultants in mid-2000 in Virginia, based on the notion to provide high-level expertise in geotechnics and tunnel engineering in support of major infrastructure projects no matter which size, where, and under which conditions. Our goal has been and will be to provide suitable engineering solutions tailored to support our clients as a reliable partner.

Based on their joint experience Vojtech and Kurt initially concentrated on the markets in the Northeast Corridor of the United States, in particular New York City and New Jersey, Washington D.C., and Boston. Soon GZ was working for major public transit authorities and tunnel contractors at national and international projects. The company grew quickly and established offices in London UK, Singapore, Santiago de Chile, New Delhi, and Toronto. Looking ahead GZ continues building iconic infrastructure for the 21st Century.
