Revisions can affect quantities, connections, coating, price, and production release.
EPC Steel Structure Procurement Support from China
China-side Control for EPC Steel Structure Procurement
YYN helps EPC procurement teams organize quotation scope, factory matching, production schedules, document status, inspection coordination, written changes, packing, and export handover through one China-side communication window.

EPC Project Guidance
YYN supports the coordination layer between the EPC team and matched Chinese production resources. The service is designed to make scope, revisions, schedule, records, inspection roles, packing, and handover easier to track without claiming to replace the EPC engineer, local approval authority, or appointed inspector.
EPC Procurement Pressure
Steel supply affects more than the purchase price.
Scope gaps
Missing accessories, documents, packing, or inspection items can appear after award.
Schedule interfaces
Production and document delays can affect shipping, site work, and the wider project plan.
Split responsibility
Factory, logistics, inspection, engineering, and site parties need a clear issue route.
Quotation & Scope Control
A comparable quotation starts with a written basis.
Production Plan & Risk
Track the baseline, current status, variance, and next action.
A production update should show more than photos. The working format can include the planned milestone, actual status, reason for variance, recovery action, open buyer decisions, and the next expected update.
BaselineConfirmed milestone plan
CurrentAssembly in progress
VarianceCoating color confirmation pending
Next actionWritten confirmation before coating release
Document Control
Use visible document status instead of scattered email memory.
PreparingSubmittedCommentedConfirmedFinal handover
| Document group | Typical records | Control point |
|---|---|---|
| Drawings | Revision register and production release status | Current revision identified |
| Materials | Agreed material documents | Contract document requirement confirmed |
| Inspection | Factory QC or third-party records | Responsible inspection party identified |
| Packing and shipment | Marks, packing list, loading and transport references | Handover checklist completed |
| Final dossier | Agreed final document index | Delivery status recorded |
Inspection Boundary
Coordination records support visibility, while formal inspection certificates are issued by the responsible inspection party.
YYN coordinates inspection dates, document requests, hold points, and record collection according to the contract. Factory quality control or the project-appointed third party performs formal inspection, while YYN organizes the agreed coordination records.
Written Change Control
Every change should have a source, impact, and confirmation.
The change register can record the originating document, affected scope, price impact, schedule impact, responsible party, confirmation status, and the updated drawing or supply basis.
Typical change triggers
- Drawing or quantity revision.
- Material or standard change.
- Coating, fireproofing, or galvanizing change.
- Inspection or document requirement change.
- Packing, delivery, or destination change.
Installation Risk Reduction
Records can reduce uncertainty, but local engineering remains local.
Freeze drawings, interfaces, connection details, bolt scope, and written changes.
Coordinate agreed dimensions, holes, member marks, accessories, and trial assembly when separately required.
Match marks to drawings, organize accessory boxes, packing sequence, loading records, and installation file handover.
Local structural engineering, site surveys, authority approvals, installation, factory quality control, and appointed third-party inspection remain with their defined responsible parties.
EPC-specific working records

Supplier Prequalification Information
Available project documents are used first, and reporting layouts are confirmed before order follow-up begins.
YYN can organize available company information, process descriptions, report formats, factory matching methods, packing examples, and real production-resource information for project review. Legal entity documents, certificates, references, and project evidence are provided only when authentic and approved for disclosure.
Define the working scope
Send your project facts, current documents, required records, and delivery target.
YYN will confirm what can be coordinated in China and which responsibilities must remain with other appointed parties.
