LMDG Building Code Consultants Ltd. was founded in 1988 as Locke MacKinnon Domingo Gibson Ltd. in Vancouver, BC.

The company began with four professionals with the common vision of providing quality fire protection and life safety building code consulting on projects across Canada. The company has grown over the years and three of the founding principals have since retired, but with over two decades of consulting experience, LMDG has established a solid reputation built on the integrity and dedication of its principals, both past and present. With two offices in Canada, the company continues to grow with its current leadership team and looks forward to sharing its values and vision with their clients, both present and future.
 

LMDG provides a wide range of services to meet specific client objectives and the particular requirements of each design project. LMDG provides professional building code, fire protection, life safety and accessibility consulting services to architects, engineers, building owners, developers, contractors, government agencies, insurers and lawyers.

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.
