Common Questions

  • How long does it take to erect a 50x100 metal building?

    Total construction times will vary depending on the location of the building, the complexity of the design, along with other factors. As a general rule, a simple 5,000 sq ft steel building can be constructed in approximately three to six weeks once the site has been cleared and leveled.

  • What does it cost to erect a 50 x 100 steel building?

    Typical construction costs can range from $5 to $10 per square foot, giving an average erection cost of $37,500. Construction costs vary depending on local labor rates, the complexity of the building, and the price of local materials such as concrete, etc.

  • How much does a 50x100 concrete slab cost?

    The average cost for a 50x100 concrete slab is $30,000. Generally, a 4-inch thick slab will cost between $3 and $9 per square foot (on average nationwide) for both the materials and labor. The final cost will mostly depend on the location of your building, as prices vary across the country.

  • How much concrete is required for a 50x100 foundation?

    A four-inch thick 50x100 slab foundation will require approx. 62 cubic yards of concrete and a six-inch foundation will need approx. 93 cubic yards.
