China-side procurement support for EPC teams
For EPC teams, the hardest part of China-sourced equipment is rarely the engineering — it is controlling the gap between the procurement package and what actually happens at the supplier’s factory, several thousand kilometres away. Sinospect works in that gap — either by supplying the equipment package itself as principal, or as a China-side execution layer when the EPC buys direct: qualifying suppliers, clarifying technical questions, planning and witnessing inspection, following documentation, and keeping the supplier accountable from award through handover.
Sinospect makes the China-side supplier evidence — capability, scope, test results, documents, non-conformities — visible and actionable before each decision is taken, so the EPC’s own engineers, procurement leads and site team are deciding on evidence rather than on a supplier’s description of itself.
Where Sinospect fits in the EPC workflow
Across a China-sourced package, the control points fall into six stages. Sinospect can support one of them or the full sequence.
Before supplier award
The qualification layer — confirming a named supplier or shortlist is real, capable and a fit for the package before the EPC commits.
- Qualify named suppliers or a shortlist.
- Check legal identity, factory capability, references, certifications and manufacturing fit.
- Identify whether the supplier is a real manufacturer, a trading company, or a weak execution risk.
During technical and commercial comparison
Making offers comparable — so the EPC team is not weighing unequal scopes against each other.
- Review the BOQ, datasheets, supplier quotations, exclusions, technical deviations, standards and documentation gaps.
- Help normalise supplier offers so the EPC team is not comparing unequal scopes.
Before purchase order or contract finalisation
Fixing the controls into the order while the EPC still has leverage — clarifications, inspection requirements and the risks that should become contract conditions.
- Clarify open technical questions.
- Define inspection, FAT and documentation requirements before leverage is lost.
- Surface risks that should become contract conditions or release milestones.
During manufacturing
Keeping the order visible between award and inspection — progress, clarifications and the status of open items.
- Follow supplier progress.
- Coordinate technical clarifications.
- Track open issues, inspection readiness and document status.
At FAT and pre-shipment
A release recommendation for the contract-assigned decision-maker, supported by witnessed results and the corrective-action record.
- Witness FAT where required.
- Coordinate pre-shipment inspection or shipment-readiness checks.
- Turn findings into release, hold, rework or corrective-action recommendations.
Before shipment and through handover
Closing the file for the site — shipment-readiness checks and continuity from receipt into commissioning and after-sales.
- Check packing, marking, serial numbers, the document pack, spares and handover records.
- Support continuity through site receipt, commissioning questions, after-sales claims, spare parts and punch-list follow-up.
Where authority stays with the EPC
Sinospect supports the EPC’s own authority. These decisions stay with the EPC:
- The EPC's engineering function.
- The owner's engineer.
- The EPC's procurement authority.
- The site or commissioning team.
Whether Sinospect supplies the package or controls an order the EPC buys direct, it supports these roles by making the China-side supplier evidence visible and actionable before decisions are taken. On an order the EPC buys direct, the technical and commercial decisions stay with the EPC. On a package Sinospect supplies, the EPC keeps its technical approvals, deviation approvals and acceptance of the package, while Sinospect takes the decisions under its own contract with the manufacturer, including release of the factory’s final balance.
Illustrative engagement structures
These illustrative scopes show the starting situation, the assigned work and the expected output.
Pre-award supplier qualification for an EPC package
- Situation
- The EPC has a shortlist of Chinese suppliers.
- What Sinospect does
- Sinospect checks legal identity, manufacturing capability, references, certifications and export/documentation readiness.
- Output
- Qualified shortlist, disqualification log, evidence pack and risk flags.
Technical review before PO
- Situation
- The EPC has a BOQ and a supplier quotation.
- What Sinospect does
- Sinospect reviews scope gaps, exclusions, standards, datasheets, document requirements, FAT needs, spare parts and unclear interfaces.
- Output
- Clarification log, deviation list, risk notes and recommended conditions before award.
FAT and shipment-release support
- Situation
- Equipment is near completion in China.
- What Sinospect does
- Sinospect coordinates FAT or PSI, checks document status, records non-conformities, follows corrective actions and supports the release decision.
- Output
- Witnessed report, photo evidence, NCR / open-issue log and a release recommendation.
Post-shipment and commissioning continuity
- Situation
- The site has an installation or start-up issue.
- What Sinospect does
- Sinospect helps rebuild the supplier-side record, coordinate with the OEM/factory, track corrective action and keep the issue documented.
- Output
- Technical brief, supplier response log, punch-list status and closure evidence.
The China-side layer behind an EPC package
On an EPC equipment package — whether Sinospect supplies it as principal or controls an order the EPC buys direct — Sinospect qualifies the supplier behind each quote, reviews the offer against the BOQ and specification, clarifies open technical questions, defines and witnesses the inspection and FAT points, follows documentation and corrective actions, checks shipment readiness, and keeps the supplier record alive through site receipt and commissioning. When Sinospect supplies, it releases the factory’s final balance after its own quality control passes. Deposits and verified milestones follow the order terms. Each step produces written evidence the EPC team can act on — and defend.
Most engagements start from a procurement package. To see what makes a package reviewable, see how to prepare a BOQ or specification. For what a witnessed FAT covers before shipment is authorised, section by section, see the FAT checklist. For examples covering technical follow-up, acceptance evidence and shipment-readiness decisions, review the field notes.

OpenFrequently asked questions
What does Sinospect do for an EPC team's China procurement?
Sinospect can supply the equipment package itself as principal, or support the China-side parts of the EPC procurement workflow when the EPC buys direct: qualifying suppliers, reviewing the BOQ and supplier quotations, clarifying technical questions, planning and witnessing FAT and pre-shipment inspection, following documentation and corrective actions, checking shipment readiness, and keeping supplier continuity through commissioning and after-sales. When Sinospect supplies, it releases the factory's final balance after its own quality control passes; deposits and verified milestones follow the order terms. The aim is to make the supplier-side evidence visible and actionable before each decision.
Which decisions stay with the EPC team?
The EPC's engineering function, owner's engineer, procurement authority and site team keep their decisions. On an order the EPC buys direct, Sinospect provides independent China-side evidence, clarifications and recommendations to support them. On a package Sinospect supplies, Sinospect also takes the decisions under its own contract with the manufacturer, including release of the factory's final balance, while the EPC keeps its technical approvals, deviation approvals and acceptance of the package.
At what stage should an EPC team bring Sinospect in?
Earlier gives more control, but Sinospect can join at any stage. Pre-award qualification and technical review are where the most risk is removed cheaply — clarifications, inspection requirements and contract conditions can still be set while the EPC has leverage. Sinospect can also be brought in later, for FAT, shipment release or a post-delivery issue.
Can Sinospect support a single stage, or only the full package?
Either. Engagements are commonly scoped to a single stage — a pre-award qualification, a technical review, a FAT, a pre-shipment inspection — or run across the full package from qualification through handover under one arrangement.
What does the EPC team receive?
Written, evidence-based deliverables: qualified shortlists and disqualification logs, clarification and deviation logs, recommended pre-award conditions, witnessed FAT/PSI reports with photo evidence, non-conformity and open-issue logs, release or hold recommendations, and continuity records through commissioning.
