Company Details

Gall Zeidler Consultants (GZ) is a worldwide leader in geotechnics, tunnel engineering and tunnel construction management, with special expertise in transportation and infrastructure projects. Our company specializes in mastering difficult ground conditions by utilizing various methods, including dewatering, grouting and ground freezing. We also specialize in tunneling under shallow overburden and protection of neighboring structures by innovatively combining conventional (NATM) and mechanical (TBM) tunneling methods with ground improvement and state of the art waterproofing techniques.

We employ over 30 staff worldwide, and can look at a history of over 170 miles of international tunneling projects completed. Our service portfolio ranges from conceptual and initial inception-level tasks—such as preparation of feasibility studies through development of tunnel designs and contractual documents—to construction management and site support services.

GZ has been involved in many national and international projects, ranging from highway tunnel construction to transit tunnel projects, and some of our specialists frequently serve on expert review panels dedicated to the investigation and improvement of tunneling structures ranging from initial inception stages through final design development at the bid document level. Our company’s peer review services relate to a wide variety of facilities ranging from hydro-power systems in remote settings to complex transit structures at shallow depths in difficult, over-built urban areas.
