Steeve Larivière, P. Eng., Chief Executive Officer - Estern Quebec

A graduate engineer in mining and mineral engineering from Université Laval, Steeve Larivière has over 27 years of experience in drilling, civil engineering, and mining environment. His career has led him to work in design, project management, operations, and corporate leadership. Since 2009, he has devoted most of his practice to trenchless technologies and has taken part in several hundred projects, including many assignments involving complex technical challenges.

This diverse experience enables him to approach each mandate with a comprehensive understanding of both technical and operational constraints. At NOEX, Steeve leverages his expertise in design, drilling and blasting, trenchless work, and risk management to guide projects toward robust, realistic solutions tailored to the specific conditions of each site.

His in?depth knowledge of both traditional and trenchless construction methods also allows him to combine different approaches when needed, in order to develop coherent and buildable concepts. His strategic vision and field experience help effectively bridge design, execution, and management considerations. As co?founder of the Trenchless Québec Show and the Trenchless Technology Association, he actively contributes to knowledge sharing and the advancement of industry practices through his involvement.

Jean-François Ménard, P. Eng., MBA, Project Manager - Western Quebec

A civil engineer and MBA graduate, Jean?François Ménard has a career that combines field experience, project management, and business development. Coming from the municipal construction sector, he was exposed early on to job?site realities and the constraints inherent to infrastructure work. His understanding of the various physical and mechanical behaviors of structures and soils naturally led him toward trenchless construction, where he can apply his analytical mindset and rigor.

Throughout his career, he has built diversified experience in estimating, project management, operations supervision, and optimization of work methods. This hands?on knowledge—particularly in trenchless work—allows him to assess multiple technical pathways and combine different methods to develop concepts suited to the real conditions of each project.

With more than 10 years of experience in the trenchless field, Jean?François leverages his civil engineering background, his MBA, and his active involvement in the industry to approach projects with a comprehensive vision. This combination enables him to develop innovative, buildable solutions adapted to technical, financial, and operational realities.
