Detailed Cost Breakdown
For a 'ballpark' estimate, consider each of these factors separately. First, choose a style – 'Rigid Frame' or 'Quonset Hut' style. Both are precision-engineered buildings manufactured to exceed your local code requirements and come in easy to assemble kit form.
Materials, Accessories & Delivery Costs:
Rigid Frame Kit:
The building kit Material cost for a 40x60 (2,400 square foot) rigid frame building cost from $7 per square foot, giving a price of $17,000. Add the delivery charge of about 7% (approx. $1,200). Consider the accessories (doors, windows etc.) necessary for your application and include 15%, (approx. $2,600). Giving you a delivered cost of approx. $20,800. Now you have the building at your site and you're all set to erect your 40x60 metal building.
If you choose a Quonset style building, your materials, accessories and delivery cost will decrease. A 2,400 square foot Quonset hut will run you about $6 per square foot (approx. $14,400) for materials, $1,000 for delivery and an additional 15% ($2,200) for accessories. The on-site, materials cost of a Quonset steel building is approximately $17,600 – representing a saving of over $3,000 over the rigid frame system.
40x60 Concrete Slab Cost:
If you are not building on an existing foundation, you will need to pour a concrete slab for your new building. You should estimate approx. $4-6 per sq ft ($9,600 to $14,400) for the installation of a 6" concrete foundation. Please see the following page for more on foundations.
Finally, you will also need to account for labor costs to build the structure. Installing it using the manufacturer’s directions may be simple, but be sure to have plenty of help for a building of this size. Some form of lifting equipment will also be required to off-load the building and raise the members into place.
