CoreField Sourcing procurement roadmap for scope checks
This roadmap is for buyers who have not closed the specification. It lists the choices that still change an alternative quotation related to a kirby building systems search. CoreField Sourcing keeps the sequence. It does not issue the engineering judgment.

- Use and occupancy
- Footprint, eave height, bay spacing
- Design wind, snow and seismic notes
- Code jurisdiction
- Quantity and destination
- Shell, delivered, installed or turnkey
Specification choices that remain open
| Clear span | State the column-free width the use actually needs. A shorter quoted span with an added column is a different building. |
|---|---|
| Eave height | Give the required eave height in feet or metres, including door headroom and any crane. |
| Bay spacing | Note a preferred bay spacing only if the process or the foundation grid demands it. Otherwise ask suppliers to propose and explain it. |
| Loads | Design live load, dead load, collateral load, design wind speed, ground snow load and seismic design category. Unknowns stay blank. |
| Covering | Single skin, insulated metal panel, or another named assembly. Do not let a supplier swap the assembly without a written deviation. |
|---|---|
| Thermal | Ask for the R-value or U-value of the quoted roof and wall, and the climate assumption behind it. |
| Fire | If the jurisdiction has named a fire-resistance rating, put that rating on the request. Do not assume a panel meets it. |
| Corrosion | Describe coastal, industrial or wash-down exposure so the coating specification can be checked against the site. |
| Volumetric modules | Confirm transport envelope, route limits and the crane lift plan before treating a module price as deliverable. |
|---|---|
| Panelized assemblies | Confirm site labor, weather protection and how long the frame is open. Packing efficiency does not remove erection. |
| Steel system | Confirm primary frame, secondary framing, purlin and girt layout, and who seals the foundation interface. |
| Acceptance | An alternative is acceptable only after the buyer records each deviation. A similar photo is not acceptance. |
Document groups to request with the quote
No files are hosted here. Each group is a request you can paste into the brief. Sizes and formats are set by the supplier who answers.
Drawings and calculations
- Anchor-bolt or foundation interface plan, marked included or excluded.
- Frame and envelope drawings for the quoted geometry, not a generic catalog span.
- Design calculations that name the code edition and the load values used.
Materials and welding notes
- Steel description and coating for primary and secondary members.
- Weld procedure reference, such as AWS D1.1, if the supplier welds the quoted system.
- Panel and fastener description tied to the exposure you reported.
Quality and accreditation papers
- Any IAS AC472 or ISO 9001 document the supplier offers, checked for the named plant and the current period.
- A statement of what the paper does not cover, including erection and local permits.
Before an alternative is accepted
Engineering
What stays unresolved if the jurisdiction is missing?
Wind, snow, seismic design category and energy or fire rules can all change. A quotation without a place is a geometry exercise. It is not evidence that the frame meets a US code.
Can a standard building be accepted on speed alone?
Only when its published limits cover the use. If the door, crane or clear span is outside those limits, the custom path is the honest comparison, even if it takes another drawing cycle.
Commercial
How should a buyer budget be read?
An optional amount, currency and per-unit or whole-order basis tell suppliers the range you want to explore. It does not create a price, a discount, or a duty to beat another brand.
What does supplier preference change?
High-end, mid-range, budget-friendly or undecided is your instruction about documentation depth and commercial range. It is not a score we have already verified, and you can send the brief with the preference still open.
Request a scope check, not a brand substitute certificate
Send the open lines and the documents you want back. Quotations that arrive can then be lined up against the same roadmap.
