Steel buildings are increasingly popular because they offer several advantages over those of traditional construction. The cost of construction can be less than one quarter of that for traditional buildings, construction time is much less, their effective life is longer, maintenance is reduced and, if properly insulated, energy efficiency is greater.
Before ordering a steel building, however, you need to know what you are getting. You can use a metal building cost calculator to get an idea of the likely cost but this may not necessarily be completely accurate.
Many factors influence the overall cost of a metal building and you need to be sure these are included so you can set a proper budget. The best way to do this is to use the services of a steel structure company that will be fully aware of what is involved and can ensure everything is included.
Typical Costs for a Steel Building
Given the complexity of construction projects, it is difficult to accurately estimate final costs. However, a steel building project comprises many elements and the costs per square foot for each are typically:
- Building kit $15-25
- Labor and installation $5-15
- Foundations $4-8
- Insulation $1.50-3
Permits and fees can cost $550-2,000 per project while the cost of windows and doors will depend on the degree of customization required. As a rough guide, these rates can result in the following costs:
- A 30×40 metal building with slab cost can be up to $60,000 depending on the finish and the complexity of the building and the foundations.
- A 40×60 shop cost can be over $100,000, with the basic shell being $7-20 per square foot and the total project being $42 or more per square foot.
- A 3,000 sq ft metal building cost can be between $300,000 and $600,000, the higher price being for a custom build with a mezzanine floor, extensive insulation and complex installations and finishes.
- 50x100x20 steel building prices range from $75,000 to $150,000 depending on the quality of materials, foundation needs and finishing.
- A 40×60 red iron building cost will typically be $10,000 to $32,000 for the shell alone, the final cost depending on the location and finish.
- A 100×200 steel building cost will generally be $30-50 per square foot, so the total cost will be $600,000-1,000,000. Add in site preparation, foundations, erection and finishing, and the cost can easily be $1.4-2.4 million.
All these costs are estimates only and can be affected by various factors. You need to get an accurate budget based on actual facts from an accredited steel construction company.
Factors Affecting Total Project Cost
Constructing a steel building involves a lot of steps, from initial planning and preparation through site preparation, construction and to finishing and handing over. All these steps can involve significant effort and expense, and the level will depend on what they include. Whilst steel buildings offer significant savings over those built by traditional methods, further savings can be made if you plan and choose carefully.
Before starting any steel building project, you need to acquire accurate costings and ensure they are in line with your budget. The final costs will be determined by a number of factors:
- The size of the building, since larger buildings require more materials and labor, which increases costs. Tall buildings require additional bracing and stronger framing to support vertical loads. Custom sizes also require specialized fabrication whereas standard sizes fit in with pre-engineered designs. Larger buildings benefit from economies of scale that result in a lower cost per square foot but the overall cost will be higher.
- Material costs, particularly steel, can affect the overall price significantly. These can be influenced by raw material shortages, global supply and demand levels and trade policies that can impose import restrictions or tariffs.
- The location of the building since local regulations can cause higher compliance costs, labor rates may vary and climate conditions, such as frequent strong winds, can require additional engineering work. A remote site or one that is difficult to access may also result in increased transport costs.
- Foundations, where the complexity will depend on local ground conditions. Unstable soil may need compaction and reinforcement while pier or perimeter foundations may be necessary rather than just a simple concrete slab.
- Design complexity, since pre-engineered steel buildings are the cheapest option but may not meet particular needs. Complex roof styles, multiple levels with increased framing and exterior customization will all add to costs. The latter includes special coatings and finishes for facades, and the size, type and placement of doors and windows.
- Increased insulation will improve the energy efficiency of the building and reduce ongoing costs but will add to the initial price. Integrating HVAC systems into the overall design, choosing high performance insulation and providing better thermal efficiency all need to be taken into account.
Anticipating and Controlling Project Costs
Although setting and adhering to a project budget is important, it should not take precedence over the quality of the building. Using cheap materials and unqualified labor will cut your initial capital costs but you will regret it later because the resulting building may be unstable and will not be as efficient as it should be.
The whole life cost of the building is the most important and includes all the running costs as well as the initial construction expense. Focusing on high quality materials and effective insulation will provide great benefits in the long term due to having a building that is durable, functional and economical to run with lower maintenance costs and an extended life.
