Where conditions shape every decision

Some projects are defined by scale. Others by environment. This one required to be addressed at the same time.

At the Greenstone Gold Mines project in Ontario, Canada, the processing facility had to operate in conditions where temperatures can drop to minus-40 degrees Fahrenheit, with sustained wind and snow adding further complexity. Construction would not pause for weather. The building had to be designed and erected with those realities in mind.

At the same time, the facility needed to support heavy industrial processes, including multiple cranes operating at different elevations and load capacities.

The solution required a structure that could perform under pressure, both during construction and long after.

Building vertically to support the process

The facility rises through three distinct roof levels; each aligned with different stages of the processing operation.

This vertical organization allows equipment and workflow to stack efficiently within the building, reducing horizontal sprawl while improving coordination between systems. It also introduces structural complexity, as each level must support its own loads while integrating with the levels above and below.

Rigid frames and lean-to framing systems were used together to create this multi-level configuration. These systems provide the flexibility needed to accommodate varying spans and elevations while maintaining overall structural stability.

Crane systems are integrated throughout the building, with capacities ranging from 5 to 46 tons. These cranes are essential to the facility’s operation, supporting the movement of materials and equipment across different stages of processing.

Designing for these loads required careful coordination. Structural members had to be sized and positioned to support dynamic forces while maintaining clear working space below.

The result is a building that functions as part of the process, supporting movement, lifting and production without interruption.

Engineering for height and assembly

The scale of the building extends vertically as well as horizontally.

Columns rise to a high eave of 129 feet, with each column spliced from four sections. This approach allows the structure to reach the required height while maintaining constructability under challenging site conditions.

Erecting these elements required precision. Each section had to be aligned and secured in an environment where cold temperatures affect both materials and equipment performance.

Wind conditions added another layer of complexity, requiring careful sequencing to ensure stability during installation. Snow accumulation further impacted access and staging, limiting how and when certain activities could take place.

Rather than treating these conditions as obstacles, the project team incorporated them into the planning process. Erection sequencing was developed to manage exposure, maintain safety and keep progress moving despite the environment.

This level of coordination reflects a broader approach, one that anticipates challenges and plans for them from the start.

Systems built for long-term performance

Beyond structure, the building envelope plays a critical role in maintaining performance over time.

The SSR™ Roof System provides weathertight protection across multiple roof levels, helping manage snow loads and prevent moisture intrusion. This is particularly important in a climate where freeze-thaw cycles can impact long-term durability.

ThermaClad™ wall systems contribute to thermal performance, helping regulate interior conditions and protect equipment from extreme temperature fluctuations.

Together, these systems create a controlled environment within the facility, supporting both operational efficiency and equipment longevity.

These are not isolated components. They are part of a coordinated system designed to perform under demanding conditions.

Delivering through coordination and expertise

Projects like this rely on alignment across teams, systems and timelines.

SteelCan Building Systems Ltd., working with Varco Pruden^™, coordinated design, fabrication and erection to ensure that each phase of the project remained connected to the next. Structural requirements, crane integration and environmental constraints were addressed early, reducing uncertainty during construction.

This collaboration allowed the team to move forward with confidence, even in conditions that would typically slow or halt progress.

Recognized as a 2024 Hall of Fame winner in the Manufacturing category, the project reflects what can be achieved when complexity is approached with clarity and coordination.

Built for demanding work

Today, the facility supports the processing demands of one of Canada’s largest gold projects.

Its multi-level structure, integrated crane systems and durable envelope allow it to operate efficiently in an environment where reliability is critical. The building is not just a container for equipment. It is an active part of the process.

For the project team, the outcome demonstrates a practical truth: when design and execution are aligned from the beginning, even the most challenging conditions can be addressed with confidence.

And in environments like this, that confidence is built into every connection, every lift and every level of the structure.
