Tunnelling
Success
Every project demands the right tools. When standard equipment isn’t enough, we do not compromise, we innovate. By combining practical experience with in-house design capabilities, we’ve developed specialized systems that make complex tunnelling safer, more efficient, and cost-effective.
Together, these tools reflect our approach: proven equipment, custom innovation, and a relentless focus on safe, reliable results.
Our fleet of Tunnel Boring Machines is equipped to handle both rock and soil in the diameters most commonly used across North America, while our in-house expertise allows us to design and build custom machines for unique conditions.
Safety is reinforced through our patented McNally Roof Support System, an economical solution that protects crews and ensures tunnel stability.
Precision installation is achieved with the McNally Air Car, which uses inflatable positioning to set pipe accurately within the tunnel.
Microtunneling is a modern, precise, and efficient underground pipeline installation method that combines remote-controlled boring and pipe jacking.
How it works -
Well Managed
As general contractors, we manage tunnelling projects from planning through completion, coordinating design input, procuring specialized subcontractors and equipment, and overseeing all site activities. We stand behind our work by delivering a complete system and providing post-project support.
