Define scope before price comparison starts
A weak RFQ usually creates weak quotations. EPC buyers should define drawings, steel tonnage, material standards, coating requirements, quality documents, packing rules, and delivery terms before asking suppliers for a firm price.

Steel Structure RFQ Package Checklist
Use this table before sending drawings to suppliers so every fabricator prices the same technical and commercial basis.
| RFQ Item | What Buyer Should Prepare | Why It Matters |
|---|---|---|
| Package map | RFQ package guide for steel structure buyers | Gives buyers the overall RFQ structure before using detailed checklists. |
| Drawings | GA drawings, structural drawings, connection details | Prevents suppliers from pricing different assumptions. |
| Scope | Included and excluded steel items | Avoids hidden exclusions and later variation claims. |
| Standards | Material, welding, coating, and tolerance standards | Controls fabrication and inspection cost. |
| Delivery terms | Incoterms, port, site, and required schedule | Controls quotation basis and export delivery responsibility. |
| Documents | MTC, welding records, coating reports, packing photos | Prevents missing evidence before shipment. |
FAQ
Buyer decision table
| Review area | Buyer decision | Evidence to keep |
|---|---|---|
| Drawing basis | Can suppliers price the same revision and connection assumptions? | Issued drawing register, revision status, connection notes |
| Scope boundary | Are supply, engineering, coating, packing, and delivery responsibilities explicit? | Scope matrix, exclusions list, Incoterms basis |
| Quotation comparison | Can price differences be traced to quantity, grade, coating, or exclusions? | Bid comparison sheet and clarification log |
Evidence checklist
- Approved RFQ document register
- Drawing and revision list
- Scope and exclusion matrix
- Quotation clarification record
Red flags
- Suppliers price different drawing revisions
- Coating or connection assumptions remain unwritten
- Exclusions are discovered only after award
Practical example
An EPC buyer receives three quotations with similar totals but different tonnage. The buyer freezes the drawing revision, issues one material takeoff basis, and records exclusions before comparing the revised offers.

Common questions for this section
What is the main purpose of an RFQ preparation checklist?
It helps the buyer define drawings, scope, standards, quantities, exclusions, delivery terms, and document requirements before price comparison starts.
When should this section be used?
Use it before sending an RFQ to fabricators, and again when supplier quotations show different assumptions or missing scope items.
What is the most important linked guide?
Start with the quotation drawing checklist because drawing completeness controls most early steel structure price assumptions.
