GKM Consultants was founded by Stéphane-Eric Thivierge, Martin Dupuis and Jean-Marie Bréhé, distinguished engineers, whom felt there was a need to bridge instrumentation technologies and complex monitoring assignment into a single turnkey servicing company for the benefit of their clients. 
 

In partnership with Geokon Incorporated, the world leader in Vibrating Wire Technology and other renowned manufacturers, GKM provides since 2007 first-class monitoring solutions services for mining, civil engineering, energy and environmental sectors in Canada and abroad. 
 

GKM procures employment to over 20 engineers with geotechnical, mining, mechanical, electrical, physics, and geological background as well as electronic and civil technicians, and proudly contribute to providing work to many local businesses where our projects take place. 

The Davenport Diamond Guideway project is part of Metrolinx’s GO Expansion program. To support future two-way all-day GO service on the Barrie line, Graham is building a rail grade separation, eliminating the Davenport Diamond crossing where the Barrie GO corridor meets the Canadian Pacific Rail tracks – one of the busiest train intersections in North America. This project represents an important transit infrastructure commitment that will improve service on the Barrie GO line while adding to the vitality of the community.
 

In 2019, Graham was selected to deliver the $175 million design-build-finance contract. The project includes construction of a new rail grade separation between GO Transit’s Barrie line and CP Rail’s North Toronto subdivision, as well as the addition of a second main line track on the Barrie line. Also included is the staged demolition and reconstruction of a rail over road bridge at Bloor Street, new rail over road bridge at Wallace Avenue, rehabilitation of rail over road bridges at Dupont Street and Davenport Road, and a pedestrian underpass at Paton Road.
 

To allow construction of the new grade separation in a logistically challenging site with an active rail line, Graham had to construct a temporary diversion track within the existing rail corridor so that Barrie train service could continue during construction.
 

Once the grade separation is complete in 2023, new public space including a multi-use path will be created underneath the raised guideway, that will enhance the community experience, improve safety and connect neighbourhoods previously cut off by the Barrie line.

Denys is an independent Belgian construction group employing 1800 people worldwide. Our growth model is based on three pillars: diversification, innovation and internationalization.

We don’t innovate in one speciality, but as a total business in several disciplines: water, energy, mobility, infrastructure, restoration, architecture and special techniques. In each of those complementary areas of expertise we have confirmed our position as a niche player and shown ourselves to be a global reference with high added value.

The world is our building site. We want to use our pioneering knowledge and get involved as widely as possible. For example, by supporting promising growth economies with crucial infrastructure projects.

The well-considered decision to diversify was without a doubt the primary motor for our growth. Today we have a firm foothold in Europe, North Africa, Sub-Saharan Africa and the Middle East. We are exploring markets such as Asia, Central and South America and Canada.

Since several years Denys is active on the German market and that is how we got involved in the strategic project Zeelink for OGE. With our multidisciplinary approach with a focus on added value, we were happy to be chosen as the partner to build the technical more difficult sections around Aachen. Pipe-by-pipe laying in narrow working areas as well as challenging microtunnels, all were successfully completed throughout the project.

Denys is proud to have been part of this Zeelink project and is actually working for OGE on its next technical very challenging project near Leverkusen.

If you can dream, we can build it. Our engineers are doing all they can to find an adequate solution for complex challenges. Hand in hand with our customers we build amazing infrastructure and this since 1923.

The Denys Group, a desirable partner for the most complex building and infrastructure projects.
