Why Two Quotes For The Same Building Come Back Thousands Apart

It happens on almost every project. Same dimensions, same eave height, same town — and the two numbers are not close.

Usually nothing is wrong with either quote. They are describing different buildings.

The three most common reasons, in order of how much money they move:

They were engineered to different loads. Wind speed and snow load drive how much steel is in the frame, and a supplier who assumed a lighter number quotes a lighter building. That is not a discount. It is a building that may not pass plan review at your address.

They include different things. One price covers the steel arriving on a truck. The other covers the steel, the concrete and a crew putting it up. Kit-only pricing generally runs $14–$19 per square foot and fully installed generally runs $23–$41, so the gap between those two definitions is larger than any discount you will negotiate. See what drives cost per square foot for the full breakdown by size.

One of them is not finished. Freight, anchor bolts, doors, insulation and engineering stamps are all line items that can be left off a quote and added later.

What A Real Quote Itemizes

Ask for the price broken out. A supplier who will not itemize is not necessarily hiding anything, but you cannot compare a single number against a list.

The line items that should be visible:

• Primary frames, purlins and girts — with the gauge and steel specification named
• Roof and wall panels — gauge, profile and finish
• Anchor bolts and fasteners
• Doors and windows — walk doors, roll-up or sliding doors, framed openings
• Insulation, if it is included at all
• Engineered drawings, and whether they are sealed
• Freight to your site, which is rarely trivial and is often quoted separately
• Foundation, which is usually not included — see foundation options
• Erection labor, likewise

Two quotes with the same total can differ by thousands once you see which of those lines is missing.

Are The Drawings Sealed For Your Jurisdiction?

This is the question that separates a quote you can build from a quote you cannot, and it is the one buyers ask least.

A metal building is engineered to a specific set of design loads — ultimate design wind speed, exposure category, ground snow load, seismic category — and then fabricated. The frames are made before your building department ever sees the drawings. If the loads were wrong, the fix is re-engineering, heavier framing, or a new order.

Those numbers are set locally, and they vary more than most people expect:

• Massachusetts publishes a ground snow load and design wind speed for all 351 cities and towns, then adds snow for sites above a town's average elevation.
• Oregon replaced its own snow load map with a national standard in 2026, and loads generally went up — so engineering prepared to the older map is out of date.
• Kansas jurisdictions publish wind speeds in two different conventions side by side, which is covered below.

Before you compare prices, get your design loads in writing from the authority having jurisdiction and give the same numbers to every supplier. Our state guides cover the code, the permit authority and the design criteria for each state we have researched.

The Wind Speed Trap

Here is a real example of two quotes that look different and are not.

Some jurisdictions publish design wind speed as an ultimate figure and others as a nominal one. The two are related by a fixed conversion, and nominal numbers are smaller for the same building. In Kansas, Wichita publishes 90 mph nominal while Olathe publishes 115 mph ultimate — and those are essentially the same requirement.

A buyer comparing a "90 mph" quote against a "115 mph" quote concludes that one supplier is cutting corners. Often both are quoting the same structure.

The natural response — buy the bigger number to be safe — is also wrong. It buys steel you do not need at a price you did not have to pay.

One question settles it: "Is that an ultimate design wind speed or a nominal one, and what exposure category did you use?"

Exposure category deserves that second clause. It moves frame weight as much as wind speed does and it is wrong more often. An open, unobstructed rural site is usually Exposure C; a building quoted at Exposure B for that site is under-designed regardless of the mph figure.

Questions To Ask Every Supplier

Send the same list to everyone you are considering. The answers are more revealing than the totals.

1. What design wind speed, exposure category and ground snow load is this engineered to, and where did those numbers come from?
2. Will the drawings be sealed by an engineer licensed in my state?
3. What is the steel gauge on the primary frames and on the panels?
4. What is included and what is not — freight, anchor bolts, doors, insulation, foundation, erection?
5. What is the lead time, and when does the price expire?
6. What happens if the building department requires a change? Who pays for re-engineering?

A supplier who answers all six has engineered your building. A supplier who answers "it meets code" has quoted a building somewhere.

One last caution. Discounted "unclaimed" or surplus buildings are usually real buildings, but they were engineered for someone else's site and someone else's loads, and those cannot be reassigned to yours. What unclaimed really means explains how those offers work before you chase one.
