Operations Support After Handover Is a Contract Gap in Every Chinese EPC You Have Seen
Quote from chief_editor on May 19, 2026, 3:30 pmChinese EPC contracts define completion at mechanical and performance completion. What comes after is almost always underspecified.
An industrial mineral processing plant in Southern Africa accepted mechanical completion from a Chinese EPC contractor in 2018 and signed the performance completion certificate fourteen months later after achieving the required throughput. The contractor team departed. Six months into full operation, the plant control system -- a Chinese-manufactured SCADA platform specified by the EPC contractor -- experienced a software fault that interrupted production for eleven days.
The operating company contacted the EPC contractor for technical support. The contractor position: the defect notification period specified in the contract had expired two months prior. Technical support was available on a commercial basis, at a day rate that had not been negotiated at contract signing. The rate quoted was not unreasonable. The plant was not in a position to negotiate because production had stopped.
The contract had been clear about what completion meant. It had not been clear about what happened after it.
What Chinese EPC Contracts Typically Include and Exclude
Standard Chinese EPC contract frameworks -- including variants of the FIDIC Silver Book adapted for Chinese contractor practice -- define the contractor obligations through a completion sequence: mechanical completion, commissioning, performance testing, and a defect notification period typically running twelve to twenty-four months.
Within the defect notification period, the contractor is obligated to remedy defects within the defined scope. After it expires, the contractor has no obligation unless the contract includes explicit provisions for ongoing support.
The provisions typically absent from Chinese EPC contracts include: a defined technical support arrangement beyond the defect notification period; a spare parts supply mechanism with agreed pricing for the operations period; a software update and license maintenance obligation for contractor-specified control systems; and an obligation to maintain the technical documentation set in a form that allows the owner to engage alternative technical support providers.
What is more specific to Chinese EPC practice is the combination of this contractual gap with three other factors: the geographic and time zone distance that makes ad-hoc technical support more difficult to access; the language gap in technical documentation that limits the owner ability to engage local alternatives; and the proprietary nature of Chinese-specified control systems and software platforms, which limits the supply of alternative technical support.
The Contract Terms That Close the Gap
A technical support agreement, annexed to the EPC contract and triggered at completion, should specify: what technical support services the contractor is obligated to provide post-completion, the response time and availability for emergency support, the pricing mechanism for non-emergency support, and the duration of the obligation.
A spare parts supply arrangement should specify: the pricing mechanism for critical spare parts during the operations period, the minimum stock the contractor is obligated to maintain in an accessible location, and the transfer of technical drawings for critical components to allow competitive sourcing if the contractor arrangement fails.
A documentation transfer obligation should specify that all technical documentation -- including software source code or access rights for contractor-specified control systems, instrumentation calibration records, and as-built drawings -- is transferred to the owner in English as a condition of performance completion.
Negotiating these provisions is easier before contract signing than after production has stopped. Whether your current EPC contract contains them in sufficient detail is a question with a concrete answer -- the contract either specifies these arrangements or it does not.
