Metal Building Kit or Design-Build Contractor?
An honest comparison so you can pick the right path for your project.
"How much does a kit cost?" is the wrong first question.
The price you see on a kit is for the steel package only. Foundation, erection, engineering, permits, and the time you spend coordinating it all are separate. Below is what an apples-to-apples comparison actually looks like.
Kit + DIY vs. SSG Firm Bid
| Factor | Kit + Self-Coordinate | SSG Firm Bid |
|---|---|---|
| Total cost | Kit price + foundation + erection + engineering + permits — sourced separately | One firm bid covering the entire turnkey scope |
| Timeline | You coordinate vendor schedules. Any gap or delay is yours to manage. | Single-source design-build with one master schedule |
| Warranty coverage | Component warranties — steel from kit supplier, foundation from concrete contractor, labor from erector | 40-year material warranty + single-source workmanship coverage |
| Permitting | Customer files and chases permits | SSG pulls permits on your behalf |
| Engineering stamps | Customer sources and pays for stamped drawings separately | Stamped drawings included in firm bid |
| Risk & accountability | Multiple vendors. When something goes wrong, you are the GC. | One contract. One PM owns the outcome. |
What a Kit Price Leaves Out
The kit price you see online usually covers the steel package. Everything it takes to turn that package into a finished building is bought, scheduled, and managed separately — by you.
- Site preparation and the concrete foundation
- Erection crew, equipment, and unloading
- Engineering stamps for your site and local code
- Permits and inspections
- Doors, insulation, gutters, and finish-out not in the package
- Your time coordinating every trade and delivery
An SSG firm bid puts all of it in one price, under one contract, before you sign.
When Does a Kit Actually Make Sense?
We are not anti-kit. They have their place. Here is when buying a kit and self-coordinating is reasonable:
- Very small, very simple buildings (under ~1,000 sq ft)
- You already have skilled erection crews and a foundation contractor on staff
- You have time to coordinate trades and pull permits yourself
- You are comfortable owning every warranty handoff
For everything else — anything serious enough to need permits, financing, or accountability — a single firm bid usually delivers better value once the real numbers are on the table.
