    Our Story and Team    

Kontur Geotechnical Consultants Inc. (Kontur) was founded in early 2018 by Matthew Yip and J.Y. (Yoshi) Tanaka.  Kontur is a full-service geotechnical consulting firm that provides engineering consultation for a wide-array of projects and clients.

In order to provide prompt service throughout Metro Vancouver and the Fraser Valley, Kontur's main office is centrally located in Port Coquitlam, BC.  Kontur also has an office in Squamish, BC, which allows Kontur to efficiently service projects throughout the Sunshine Coast and Sea to Sky regions.

Kontur is comprised of three Principal Geotechnical Engineers: Evan Sykes; Yoshi Tanaka; and Matthew Yip.  Combined, Evan, Yoshi, and Matthew, have over 50 years of geotechnical engineering knowledge and experience in British Columbia and Alberta, Canada.

Kontur's key team of individuals are noted below:

  • Matthew Yip, M.Eng., P.Eng., CEO + Principal Geotechnical Engineer.  Matthew has over 14 years of geotechnical engineering experience focused on materials testing, geotechnical explorations, characterizations, assessments, geological hazard evaluations (landslide assessments), and geotechnical designs for various buildings, facilities, and infrastructure.  Matthew is a Professional Engineer (P.Eng.) registered with both the Engineers and Geoscientists of British Columbia (EGBC) and the Association of Professional Engineers and Geoscientist of Alberta (APEGA).  Matthew holds a Bachelors degree in Geological Engineering, as well as a Masters of Engineering degree in Geological Engineering, both from the University of British Columbia

  • J.Y. (Yoshi) Tanaka, P.Eng., COO + Prinicipal Geotechnical Engineer.  Yoshi has over 14 years of geotechnical engineering experience focused on geotechnical explorations, characterizations, assessments, and geotechnical designs for various buildings, facilities, and infrastructure.  Yoshi's experience has included various components of geotechnical earthquake engineering analysis and soft/compressible ground analysis.  Yoshi is a Professional Engineer (P.Eng.) registered with the Engineers and Geoscientists of British Columbia (EGBC).  Yoshi holds a Bachelors degree in Geological Engineering from the University of British Columbia.

  • Evan Sykes, P.Eng., Principal Geotechnical Engineer.  Evan has over 29 years of geotechnical engineering experience focused on geotechnical and geophysical explorations, characterizations, assessments, geological hazard evaluations (including rock slope stability), and geotechnical designs for various buildings, facilities, and infrastructure.  Evan is a Professional Engineer (P.Eng.) registered with the Engineers and Geoscientists of British Columbia (EGBC).  Evan holds a Bachelors degree in Geological Engineering from the University of British Columbia.

  • Brian Mylleville, Ph.D., P.Eng., Senior Project Manager + Geotechnical Engineer.  Brian has over 29 years of Geotechnical Engineering Consulting experience focused on geotechnical explorations, characterizations, assessments, and studies, for various buildings, facilities, and small- to large-scale infrastructure projects.  Brian's experience has included various components of embankments, engineered slopes, dikes, and use of geosythetic materials.  Brian is a Resistered Professional Engineer in British Columbia, Alberta, Saksatchewan, and Ontario.  Brian holds a Bachelors of Engineering Science and as well as a Doctorate in Engineering Science, both obtained from Western University.
