Modular Mining Building — what you are buying
The modular mining building is one of the most requested configurations we quote, and it is also one of the most inconsistently priced across the industry. Suppliers publish a per-square-foot figure, leave out foundation, freight, crane and permitting, and the number a buyer eventually pays lands well above what they planned around. We publish the unit price and the site costs separately so the comparison is honest.
| Typical cost per square foot (new) | $310 |
| Premium specification per square foot | $420 |
| Configurations priced | 6 |
| Price range (new) | $62,000 – $196,000 |
| Production window | 30–90 days, queue dependent |
| On-site set | 2–8 hours typical per unit |
| Delivery | All 50 states · $7 per loaded mile |
New versus used versus rental
New units carry full warranty, current code compliance and the finish level you specify. Used and refurbished inventory typically runs forty to sixty percent below new, with the trade-off being available configurations rather than condition — a refurbished unit is stripped, inspected, repaired and re-finished, but you take the floor plan that exists. Rental makes sense under roughly eighteen months of use; past that point, cumulative rent generally exceeds purchase price and you own nothing at the end. Run the arithmetic on your actual duration before defaulting to rental because the monthly number feels smaller.
What actually drives the price
Size is the obvious variable, but it is rarely the one that moves a quote the most. Finish level, mechanical capacity, code requirements in your jurisdiction, and site conditions all shift the total more than a few extra square feet. A unit destined for a high-wind coastal county needs impact-rated openings and engineered tie-downs. A unit for a site with no municipal sewer needs a septic system. Neither of those is visible in a per-square-foot figure, which is exactly why we break them out.
Lead time and why it is a range
We quote 30 to 90 days as a production window rather than a delivery date, and the reason is supply and demand. Factory queue depth changes weekly. Material lead times on steel, windows and finish goods have tightened this year and seasonal demand compresses the calendar heading into spring. A slot confirmed today holds at the window we quote. A slot considered for six weeks usually reprices, because the block it was going into has filled.
Every configuration priced
8 x 20 control room
At 8 x 20 control room, expect roughly $62,000 new, $37,200 refurbished, or $1,850 per month on rental. This size typically clears standard highway transport without special permitting, which keeps freight predictable.
10 x 40 dry house
At 10 x 40 dry house, expect roughly $98,000 new, $58,800 refurbished, or $2,650 per month on rental. Availability on this size varies with the production block, so confirm before planning around it.
12 x 40 blast-resistant
At 12 x 40 blast-resistant, expect roughly $148,000 new, or $4,200 per month on rental. Availability on this size varies with the production block, so confirm before planning around it.
12 x 40 blast-resistant Zone 2
At 12 x 40 blast-resistant Zone 2, expect roughly $167,000 new, or $4,750 per month on rental. Buyers often size up from here once they see the marginal cost per additional square foot.
12 x 60 refuge chamber
At 12 x 60 refuge chamber, expect roughly $196,000 new, or $5,400 per month on rental. Buyers often size up from here once they see the marginal cost per additional square foot.
24 x 40 wash / change house
At 24 x 40 wash / change house, expect roughly $178,000 new, $106,800 refurbished, or $4,900 per month on rental. This is one of the more common configurations we ship and inventory moves quickly on it.
Why buy from us
Quality you can actually compare
Every unit off a line is built to the same specification with the same crews and the same materials. That repeatability is impossible to achieve across independent site-built projects with rotating subs. If you inspect one finished unit, you have meaningfully inspected the one you are buying.
Factory conditions beat weather
A module built indoors never sits in the rain waiting on a framing crew. Lumber does not swell, drywall does not wick moisture, and the schedule does not slip because a storm parked over the site for nine days. That single difference — controlled environment versus open air — is most of why factory-built assemblies test tighter on a blower door than comparable site-built work.
Two schedules running at once
Site-built construction is sequential: permit, then excavate, then frame, then finish. Factory-built runs the site work and the building in parallel. While your foundation is being poured and utilities are being trenched, the structure is already being framed and finished on a production line hundreds of miles away. That overlap is where the calendar savings actually come from, not from anyone working faster.
Inspected more, not less
There is a persistent assumption that factory-built means less oversight. The opposite is true. Modules are inspected at multiple stations during production by third-party agencies, then inspected again on site after the set. A conventional stick-built house typically sees an inspector four to six times total. A modular unit is checked at every stage where a defect could be hidden by the next layer.
