30x60 Metal Building With Slab: Cost Breakdown
A 30x60 is 1,800 square feet in a long, narrow footprint — the classic shape for agricultural equipment storage, a multi-bay shop, or anything that needs drive-through access from end to end. Three bays of 20 feet is the standard framing, which gives you clean interior organization without interior columns.
The long footprint is efficient to buy and slightly tricky to pour. A 60-foot slab shrinks along its length as it cures, and that is the main thing to get right on the concrete side. Here is the full turnkey cost breakdown and what the foundation has to handle across four frame lines.
What a 30x60 Actually Costs, Line by Line
30′ × 60′ = 1,800 square feet. The ranges below are typical 2026 market costs from building suppliers and concrete contractors — they are not SteelReady quotes. Regional pricing, design loads, and specification move every line.
| Line Item | Per SF | 30x60 Range | What Moves It |
|---|---|---|---|
| Building kit (delivered) | $9–$17 | $16,200–$30,600 | Gauge, eave height, doors, insulation, snow/wind loads |
| Concrete slab + footings (installed) | $7–$13 | $12,600–$23,400 | Thickness, rebar, joint layout, site prep, local concrete price |
| Erection labor | $4–$8 | $7,200–$14,400 | Crew size, site access, eave height |
| Site prep, permits & misc. | $2–$5 | $3,600–$9,000 | Grading, utilities, permit fees, geotech report |
| Turnkey total | $22–$43 | $39,600–$77,400 | Everything above, combined |

Why Two 30x60 Quotes Can Be $20,000 Apart
This is one of the best value shapes available. You are buying 1,800 square feet at a 30-foot span, which means light frames, manageable reactions, and simple foundation details — with the square footage coming from cheap length rather than expensive width. Per square foot, a 30x60 is among the most economical configurations in the standard lineup.
Grading gets more expensive as buildings get longer. A 60-foot run has to be flat. On a sloped site, the cut and fill required to level a 60-foot pad is considerably more than for a 40-foot pad, and any fill under the slab has to be engineered and compacted — you cannot pour a structural slab on loose fill. On a sloping lot, site prep can quietly become the largest surprise line item.
Consider door placement early. Drive-through access means overhead doors on both 30-foot endwalls. That is two door openings, two sets of jamb reinforcement, and two headers — plan it in the original order rather than as a change.
Four frame lines, three bays. The standard 20-foot bay spacing at this length gives eight columns. More columns means each footing is smaller, which is generally good for cost.
Concrete for a 30x60 Slab
A 30x60 slab is 1,800 square feet with 180 linear feet of perimeter. A 4-inch slab field is roughly 22 cubic yards; with thickened edges and column footings most pours land between 29 and 33 cubic yards — three to four truckloads.
Joint layout is the critical detail on a long slab. Concrete shrinks roughly proportionally to its length as it cures, and a 60-foot pour will develop meaningful shrinkage strain along its long axis. Without a planned control joint pattern, that strain relieves itself as random transverse cracks. The standard approach is a joint grid producing panels no larger than about 12 to 15 feet on a side for a 4-inch slab, with joints cut early — typically within the first day, before the concrete has gained enough strength to crack on its own.
Keep joints aligned with the column lines where possible, and never run a control joint through a footing or a thrust-restraint detail. Coordinating the joint plan with the structural layout is a five-minute conversation that prevents a permanent problem.
What the Foundation Has to Do at 30x60
Eight columns, well distributed. With four frame lines at 20-foot spacing, the load is spread across more footings than on a shorter building, and each individual footing is correspondingly more modest. Interior frames still carry roughly twice the tributary area of the endwall frames, so footings are not uniform.
The 30-foot span keeps thrust moderate. As with the 30x40 and 30x50, horizontal thrust at the column bases is real but usually handled with a thickened edge or a straightforward hairpin detail rather than tie rods.
Differential settlement is the long-building risk. Sixty feet is enough distance for soil conditions to vary meaningfully from one end of the building to the other — particularly on a site with cut at one end and fill at the other. If one end settles and the other does not, the frame racks, doors bind, and the slab cracks. This is the size where a geotechnical report with borings at both ends genuinely earns its cost.
Fill has to be engineered. On a graded site, any structural fill beneath footings needs to be placed in lifts and compacted to a specified density, with testing. Footings bearing on uncontrolled fill are a rejection at inspection and a settlement problem afterward.

30x60 Metal Building Questions
- How much does a 30x60 metal building with a slab cost?
Turnkey, most 30x60 projects run roughly $40,000 to $77,000 in 2026. Per square foot this is one of the more economical standard sizes, because the floor area comes from added length rather than added span.
- How much concrete does a 30x60 slab take?
About 22 cubic yards for a 4-inch slab field, and typically 29 to 33 cubic yards including thickened edges and column footings — three to four truckloads.
- How do I keep a 60ft slab from cracking?
You do not prevent cracking — you control where it happens. A planned control joint grid with panels no larger than roughly 12 to 15 feet per side, cut early while the concrete is still gaining strength, gives the shrinkage somewhere to go. Adequate reinforcement, a proper vapor barrier, and a well-compacted subgrade do the rest.
- Do I need a soils report for a 30x60 on a sloped lot?
We would strongly recommend it. A 60-foot building on a graded site frequently has native soil under one end and engineered fill under the other, which is exactly the condition that produces differential settlement. Borings at both ends let us design footings appropriate to what is actually there.
