The Dr. Sauer Group is your partner for cost effective and innovative tunnel design
The Dr. Sauer Group has been in practice for over 25 years. It was established by Dipl. Ing. Dr. Sauer, the Principal of the Group and today employs engineers and other staff at four international offices located in Salzburg, Austria (Est 1979); Washington DC, USA (Est. 1984); London, United Kingdom (Est. 1987); and New York, USA (Est. 2003).
The company's philosophy is based on the belief that motivation is derived from the individuals' success and that profession is a passion and not a burden. At the Sir Julius Wernher Memorial Lecture 'When an Invention is something new - From Practice to Theory in Tunneling 1988', Dr. Sauer expressed this with Bertrand Russell's quote: 'The secret of happiness is this: let your interests be as wide as possible, and let your reactions to the things and persons that interest you be as far as possible friendly rather than hostile'.
Upon formation, the Group provided cost effective and innovative tunneling solutions to contractors. The benefits of such were quickly embraced by owners and today the Group is recognized as one of the leading consultants for design and construction supervision of tunnels and underground structures.
The Dr. Sauer Group has undertaken feasibility studies, conceptual design, detailed design and construction supervision, as well as expert witness and insurance risk management services for worldwide projects in a variety of environments. The experience of the Group's staff covers all aspects of tunneling engineering including, geotechnical, geological, structural design and rock support. The Group has provided consultancy and construction supervision services to a wide range of clients including owners, other consultants and contractors.

The Dr. Sauer Group's Developments
The Doorframe Slab Method (DFS), a modified cut-and-cover technique which reduces the depth and disruption of open trench projects. The Barrel Vault Method (BVM), for shallow tunneling under buildings, or through railway embankments without disrupting surface operations. The Grouted Spile Anchor (GSA), for pre-stabilization of non-cohesive soil in one integrated step. The Drainage Rehabilitation System (DRS), which effectively controls water seepage to prevent deterioration of the underground structure, corrosion of mechanical and electrical equipment, helps to eliminate safety hazards and thus prolong structure life. The Waterproofing System (WS), membrane type for cut-and-cover stations, shafts, mechanized and mined tunnels and underground structures, with remedial repair system. The Caisson Method (CM) - patent pending, for underwater tunneling such as river crossings.
