1. Initial cost
- Traditional construction: The cost of construction depends on a number of factors, including the type of materials used (concrete, steel, wood), labor and construction time. In 2023, average prices for residential construction ranged from $1,500 to $3,000 per square meter, depending on region and specification.
- Modified container infrastructure: The price of a standard shipping container varies according to its size (20 or 40 feet) and condition (new or used). On average, a 40-foot container costs between $2,500 and $5,000. Modifications, such as the addition of doors, windows, insulation and electrical systems, can add between $10,000 and $30,000, depending on specific needs. Overall, the cost per square metre of a container structure is often between $1,000 and $2,500, which is generally lower than traditional construction.
2. Construction times
- Traditional construction: Construction time for a house or commercial building generally varies from 6 to 18 months, or even longer, depending on the size of the project and possible delays caused by external factors such as the weather.
- Modified container infrastructure: Container-based construction is significantly faster. Units can be prefabricated and modified in the factory, then delivered and installed in just a few weeks. Total construction time can be reduced to 1-3 months, including site preparation.
3. Labor
- Traditional construction: Labor represents a significant portion of the overall cost, as specialized crews are often required for each phase of the project (carpenters, electricians, plumbers, etc.). This can quickly add up.
- Infrastructure in modified containers: Thanks to the prefabrication and modularity of the units, the labor required is reduced. Numerous customizations (addition of windows, insulation, etc.) can be carried out in the workshop, reducing on-site labor costs.
4. Maintenance and durability
- Traditional construction: Although solid, traditional buildings require regular maintenance (painting, roof repairs, etc.), which generates additional costs over the long term.
- Modified container infrastructure: Containers are designed to withstand harsh conditions, such as shipping and the elements. The corten steel used in their manufacture is corrosion-resistant, which considerably reduces long-term maintenance costs.
5. Environmental impact and sustainability
- Traditional construction: the production of materials such as concrete and steel is energy-intensive and generates significant CO₂ emissions.
- Modified container infrastructure: By reusing containers, environmental impact is reduced. Fewer new materials are needed, and modifications generally produce less waste than traditional methods.
Cost comparison: Real-life examples
- 200 m² commercial building:
- Traditional construction: Approximately $300,000 to $600,000, depending on materials and region.
- Modified container infrastructure: Between $200,000 and $500,000, depending on degree of customization and insulation and finishing materials.
- 150 m² residential dwelling:
- Conventional construction: Between $225,000 and $450,000.
- Modified container infrastructure: Between $150,000 and $300,000.
Conclusion
Modified container infrastructure is both a more economical and faster solution than traditional construction. It also offers greater flexibility and durability. Whether for commercial or residential projects, this option stands out as a viable alternative, particularly for those seeking ecological, fast and customizable solutions.
