Mining Equipment Maintenance Buildings for Heavy Equipment
Mining equipment maintenance buildings need to accommodate more than maintenance crews and tools. On a large mine site, the building may need to provide enough clear height, door clearance and unobstructed interior space for haul trucks, loaders and other heavy mobile equipment while supporting maintenance work in demanding operating conditions.
For Canadian mining operations, the building also has to be engineered around the actual project location, environmental loads, foundation conditions and intended use.
GNB Global designs, engineers, manufactures and installs large-scale tension fabric structures for mining and industrial applications. These structures can be configured as mining equipment maintenance buildings where large clear-span interiors, heavy-equipment access and rapid project delivery are important considerations.
GNB has delivered engineered structures as large as 400 feet by 600 feet, or 240,000 square feet, allowing building designs to be developed around substantial industrial operations rather than small commodity shelter applications.
Quick Facts About Mining Equipment Maintenance Buildings
For mine operators and project teams planning a heavy-equipment maintenance facility:
Clear-span construction can eliminate interior columns that interfere with equipment movement and maintenance layouts.
Door size, clear height and equipment dimensions should be established before the building is engineered.
GNB has delivered structures up to 400' × 600', or 240,000 square feet.
GNB structures can be insulated for applications requiring greater environmental control.
Structures can be engineered for applicable site-specific North American wind and snow requirements.
GNB is a CSA-A660 certified manufacturer.
Typical GNB project lead time is approximately 12–16 weeks, depending on engineering, size, site conditions and project requirements.
Temporary, semi-permanent and permanent configurations can be developed depending on project requirements.
What Should a Mining Equipment Maintenance Building Include?
A mining equipment maintenance building should be designed around the equipment, maintenance activities and operating requirements that will exist inside it.
Before determining the final dimensions, project teams should understand what equipment will enter the building, how it will move through the facility and what work crews need to perform around it.
Important considerations can include:
Equipment width, height and length
Door width and height
Clear interior height
Number of maintenance bays
Equipment turning and circulation
Maintenance clearances
Parts and tool storage
Material-handling equipment
Personnel areas
Lighting requirements
Ventilation requirements
Heating and insulation
Foundation conditions
Future equipment changes
For a large mining operation, designing the building around a generic footprint and addressing equipment access afterward can create unnecessary restrictions.
The equipment and maintenance workflow should help establish the building requirements from the beginning.
Why Is Clear-Span Space Important for Heavy Mining Equipment?
Clear-span space allows large mining equipment to move and be positioned without interior structural columns obstructing the work area.
That can be particularly important in facilities servicing large mobile equipment.
Interior columns may affect:
Equipment positioning
Turning movements
Maintenance access
Bay configurations
Material handling
Future layout changes
Usable floor area
A clear-span structure allows the project team to configure the interior around the maintenance operation rather than designing the operation around structural columns.
This distinction becomes increasingly important as equipment size increases.
GNB has delivered engineered structures as large as 400 feet wide by 600 feet long, demonstrating the scale available for large industrial building applications.
The appropriate dimensions for a maintenance facility, however, should be determined by the mine's actual equipment fleet and operational requirements rather than simply selecting the largest available structure.
How Should Door Size and Equipment Access Be Planned?
The largest equipment expected to use the facility should help determine door dimensions, clear height and building access requirements.
Project teams should identify these requirements before final engineering.
Consider:
The tallest equipment entering the building
The widest equipment entering the building
Required clearance around equipment
Approach angles
Turning requirements
Door operating space
Traffic flow
Whether equipment must enter and exit from opposite sides
Future equipment purchases
Maintenance equipment used around the vehicle
A door opening that technically accommodates a piece of equipment may still create operational problems if the approach or interior clearance is inadequate.
This is why GNB's large mining and industrial structures are engineered around the project's intended application rather than treated as one-size-fits-all shelters.
Can Mining Maintenance Buildings Be Insulated for Canadian Winters?
Yes. GNB tension fabric structures can be insulated for mining applications requiring greater environmental control.
For maintenance operations in Canada, insulation can be an important consideration because crews may need to work inside the facility throughout the year.
Conditions vary considerably between mining regions in Saskatchewan, Ontario, British Columbia, Quebec, Manitoba and northern Canada.
A maintenance building's environmental requirements should therefore be established according to its specific location and intended use.
Project teams should consider:
Required interior operating temperature
Occupancy
Equipment maintenance activities
Ventilation requirements
Door-opening frequency
Heat loss through large equipment doors
Local climate
Insulation requirements
Mechanical systems
A building used primarily for cold equipment storage has very different requirements from an occupied maintenance shop where technicians work throughout a Canadian winter.
These requirements should be coordinated during design rather than addressed after the structure has been manufactured.
How Are Mining Maintenance Buildings Engineered for Wind and Snow?
Mining maintenance buildings should be engineered for the applicable wind, snow, seismic and code requirements of the actual project location.
A generic structural rating is not appropriate for every Canadian mine site.
GNB can engineer structures according to applicable North American wind and snow requirements based on the specific project location.
Engineering considerations may include:
Wind loads
Snow loads
Seismic requirements
Building dimensions
Exposure
Site conditions
Foundation design
Building use
Applicable codes
This matters because Canadian mining operations can be located in substantially different environmental conditions.
A potash operation in Saskatchewan should not automatically be treated as having the same structural requirements as a mine in northern Ontario, British Columbia or Canada's North.
GNB is also a CSA-A660 certified manufacturer.
For owners, engineers and EPC/EPCM firms, the key question should be whether the proposed structure is engineered for the specific mine site and intended application, not simply whether the supplier offers a standard building in the required dimensions.
What Foundation Should Be Used for a Mining Maintenance Building?
Foundation selection depends on the building design, structural loads, site conditions, intended use and engineering requirements.
There is no single foundation approach appropriate for every mining maintenance facility.
Foundation planning should consider factors such as:
Geotechnical conditions
Frost conditions
Structural loads
Building classification
Floor requirements
Equipment loads
Site preparation
Intended building lifespan
Future relocation plans
Applicable codes
Heavy equipment can also introduce requirements beyond those associated with the building structure itself.
The structural foundation and the floor or operational surface used by mining equipment are not necessarily the same design problem.
For that reason, foundation, building and equipment requirements should be coordinated by the appropriate project engineering teams.
How Quickly Can a Mining Maintenance Building Be Deployed?
GNB's typical project lead time is approximately 12–16 weeks, although the actual schedule depends on engineering, building size, location, site conditions and project scope.
GNB has completed a structure installation in as little as one day on select projects.
That does not mean every maintenance building can be installed in one day.
Installation time can be affected by:
Structure size
Foundations
Site readiness
Location
Weather
Access
Mobilization
Building configuration
Installation scope
For a mine operator, the important consideration is how the building schedule fits into the larger capital project, shutdown, expansion or operational plan.
A rapidly installed structure can be particularly valuable when a mine needs additional maintenance capacity without committing to a lengthy on-site building programme.
However, speed should not replace proper engineering.
The objective should be to combine an efficient project schedule with a structure designed for the actual operating environment.
Can a Mining Maintenance Building Be Expanded or Relocated?
Many GNB structures can be designed to allow future expansion, reconfiguration or relocation.
This can be useful for mining operations because equipment fleets and infrastructure requirements may change throughout the life of the mine.
A facility might initially require several maintenance bays and later need additional capacity.
A building used during construction or mine expansion may eventually be required elsewhere on the property or potentially at another operation.
If future expansion or relocation is anticipated, those requirements should be identified during initial engineering.
Not every structure is automatically expandable or relocatable simply because it uses tension fabric construction.
Designing for future flexibility from the beginning gives the engineering team the opportunity to account for those requirements properly.
How Long Can a Mining Equipment Maintenance Building Last?
GNB architectural fabric typically has an expected service life of approximately 15–20 years, depending on the environment, application and maintenance.
GNB's U.S.- and Canadian-made steel framing can provide 30+ years of service, depending on conditions and maintenance.
For mine operators evaluating lifecycle cost, the fabric and structural frame should therefore be considered separately.
Other lifecycle considerations can include:
Corrosion protection
Maintenance requirements
Fabric replacement
Foundation investment
Insulation systems
Relocation potential
Expansion requirements
Mine life
Future use of the building
The lowest initial building price does not necessarily represent the lowest long-term cost for a large mining operation.
The appropriate comparison should consider how the facility will support maintenance operations throughout its intended service period.
When Does a Tension Fabric Maintenance Building Make Sense Compared With Conventional Construction?
A tension fabric building can be a strong option when a mining project needs large clear-span space, an efficient deployment schedule or future flexibility, but it is not automatically the right solution for every maintenance facility.
Conventional construction may be preferable where the project requires building systems or architectural conditions better suited to that construction method.
Tension fabric structures may warrant consideration where priorities include:
Large unobstructed interiors
Heavy-equipment access
Rapid deployment
Remote-site construction
Future expansion
Potential relocation
Large covered work areas
The decision should be based on lifecycle requirements, engineering, operational needs and project economics rather than assuming one construction method is universally superior.
For sophisticated mining projects, comparing both approaches early can help the project team identify which system best fits the operation.
GNB Experience With Large Mining Infrastructure
GNB specializes in large engineered structures for mining and industrial projects, rather than small commodity fabric shelters.
GNB's largest mining project to date is its work with Nutrien in the potash industry.
GNB has also delivered structures measuring up to 400 × 600 feet, or 240,000 square feet, providing experience with the scale required for major industrial facilities.
For Canadian mine owners, EPC/EPCM firms, engineering companies and contractors, GNB can participate early in project planning to evaluate building dimensions, equipment requirements, structural engineering, environmental conditions and deployment strategy.
As additional approved information about the Nutrien project becomes available, specific dimensions, building applications and project details should be added here to provide additional first-party evidence of GNB's mining capabilities.
Frequently Asked Questions About Mining Equipment Maintenance Buildings
What size should a mining equipment maintenance building be?
