Professional Background
Mr. Wolczko has been employed as a geotechnical engineer for over 30 years, and has been involved in numerous geotechnical projects. He has worked predominately in the Puget Sound region, but also worked on several projects in the western United States and on a project overseas.

After receiving his bachelor's degree, Mr. Wolczko worked for Golder Associates, Geotechnical Consultants in Seattle, Washington until 1980. During that time he worked as chief of the laboratory and performed construction monitoring services. He was involved in a major environmental groundwater study in eastern Wyoming and construction of an earthfill mine tailings dam in Utah.

Mr. Wolczko joined Shannon & Wilson, Inc. in 1980 and remained there until 2004. During his time with Shannon & Wilson, he gained extensive experience in all phases of geotechnical engineering. He was responsible for coordinating and conducting site explorations, performing engineering studies, preparing reports, and monitoring construction. On many of these projects he served as the project manager. He has worked on numerous residential, commercial and industrial projects, municipal improvements, hospital and educational facilities, and landslide studies and remediation. His efforts on these projects have varied from short site visits to long-term field assignments.

On two occasions (1981 and 1990/1991) while employed with Shannon & Wilson, Inc., Mr. Wolczko was the Resident Geotechnical Engineer for the expansion of the P.T. Semen Cibinong cement plant near Jakarta, Indonesia. During the 15-month period in 1990/1991, he was involved in all phases of the geotechnical field work for the $250 million expansion. The project site is located in an area of Karst geology, and the plant site is underlain by numerous solution features that extended from small cracks up to several large caverns. Shannon & Wilson was responsible for providing recommendations for foundation design and remedial measures to provide additional support where solutioning had compromised areas beneath structures. Throughout the project, Mr. Wolczko acted as the liaison between numerous subcontractors and the owner, and oversaw the day to day operations related to geotechnical aspects of the project.

Since 2004, Mr. Wolczko has worked for Yonemitsu Geological Services (YGS). While with YGS he has been involved primarily on the Sound Transit, ULink, and Brightwater projects. His responsibilities have included observing and logging subsurface explorations, installing and reading instrumentation, monitoring construction, and providing a geological/engineering review of soil core obtained from subsurface explorations.

In 2004, Mr. Wolczko established Sound Geotechnical, PLLC and began providing consulting services on geotechnical engineering projects, working primarily on Vashon and Maury Island.

Beginning in 2009, Mr. Wolczko began working with EnviroSound Consulting. Mr. Wolczko and Mr. Williams with EnviroSound had worked together while at Shannon & Wilson. Mr. Wolczko has worked on over 20 projects with EnviroSound primarily conducting engineering analyses and preparing reports for large commercial projects as well as residential projects.
