Tunneling is already one of the most complex and high-risk types of construction. Add in confined spaces and emissions concerns, and the challenges multiply fast. In these environments, finding the right portable, temporary lighting for construction isn’t just a question of efficiency. isn’t just a question of efficiency, It’s about health, safety, and long-term project viability.

Recently, we had the chance to support a large, multi-year tunnel infrastructure project in Quebec. While we can’t name the client due to confidentiality agreements, the work itself offers a brilliant example of how the right zero-emission lighting solution – applied consistently over four years – can reduce costs, eliminate emissions, and help teams work smarter underground.

The Challenge: Emissions Restrictions in a Confined Space

Our client’s crews were building a major tunnel in Quebec, where diesel equipment posed a serious risk. With limited ventilation and constant concerns about carbon monoxide buildup, running traditional diesel-powered light towers inside the tunnel just wasn’t an option – a diesel alternative lighting solution was non-negotiable.

But we all know, work can’t wait. Which is where Axiom came in to provide the team with bright, reliable lighting, particularly crucial during phases where permanent tunnel lighting had not yet been installed.

Axiom’s Solution: Zero-Emission Light Towers That Run on Shore Power

To help overcome these constraints, we supplied the project team with our ELT-4320 Electric Light Towers – featuring four high-output 320W LED heads. Unlike diesel towers, these electric units could plug directly into shore power, delivering consistent lighting without generating any harmful emissions.

The towers provided powerful, flicker-free illumination deep in the tunnel, keeping crews safe and the work moving forward without compromising air quality. This kind of temporary construction lighting was ideal for the unique challenges of working in confined spaces.

The Results: Cleaner, Cheaper, and Zero-Maintenance Lighting

The switch from diesel to electric lighting wasn’t just safer; it was a smart financial move too. Over the course of this four year project, the project team reduced their lighting-related operating costs by over 80%, saving more than $700,000 CAD.

Other benefits included:

  • Zero carbon monoxide emissions in the tunnel
  • No service or maintenance required for the electric towers
  • Silent operation, which reduced noise levels for teams working underground

When you’re working in tight quarters and high-stakes conditions, gear that works quietly and reliably in the background makes all the difference.

Lighting the Path for Future Underground Projects

At Axiom, we don’t just rent equipment: we help solve problems. For this Quebec infrastructure project, that meant offering a zero-emission lighting solution that was as smart and safe as it was simple.

Whether you’re working on tunnel construction or building a road through the wilderness, our goal is to help you get the job done, cleanly, safely, and on budget.
