The Cheapest Chinese EPC Always Has the Thinnest Engineering Team
Quote from chief_editor on May 26, 2026, 3:30 pmChinese EPC contractors competing on price systematically reduce engineering team depth. The consequence shows up not during construction but during commissioning and the first year of operation.
A natural gas processing plant in Central Asia was commissioned in 2019 under a Chinese EPC contract. The EPC contract price was approximately 28% below the competing European offer. The decision to award to the Chinese EPC was made at the board level, with the price differential as the primary factor.
The commissioning period ran eleven months beyond the contractual completion date. The primary technical bottleneck was not equipment performance -- the equipment generally met its specifications. The bottleneck was process integration engineering: the management of interactions between the inlet separation system, the compression train, the dehydration unit, and the export metering system at off-design operating conditions that had not been fully modeled during the FEED stage.
The Chinese EPC contractor had four process engineers assigned to the project at commissioning. Two had less than five years of post-graduate experience. The troubleshooting that consumed the eleven months was largely performed by the owner's own engineering team and two external consultants retained at the owner's cost.
How EPC Price Competition Produces Thin Engineering Teams
Chinese EPC contractors competing on price are making a systematic trade-off between engineering investment and project margin. The construction and procurement elements of an EPC project have relatively transparent cost structures -- steel tonnage, equipment vendor prices, labor rates -- that are difficult to dramatically undercut without sacrificing quality. The engineering element has a more flexible cost structure. Engineering staff costs can be reduced by using less experienced engineers, by reducing team size, and by deferring detailed engineering work to the construction phase when problems become visible.
The consequence of this trade-off does not manifest during construction. It manifests during commissioning, when the engineering decisions that were made -- or not made -- during detailed engineering have to be resolved in a live plant environment against a completion schedule.
An experienced process engineering team produces detailed commissioning procedures, identifies potential process integration issues during the pre-commissioning stage, and has the depth of knowledge to troubleshoot unexpected operating conditions quickly. A thin or inexperienced engineering team produces generic commissioning procedures, encounters process integration issues during actual commissioning that were predictable from the process simulation, and requires external support to resolve them.
Industry estimates suggest that EPC contractors pricing at 25% or more below competing offers are typically recovering that gap through some combination of thinner engineering teams, more aggressive procurement of equipment at lower specification tiers, and more optimistic assumptions about construction productivity that result in site cost overruns. The engineering team reduction is the component that has the most concentrated impact on commissioning performance.
The Evaluation Criteria That Surface Engineering Depth
The standard EPC tender evaluation asks for CVs of key personnel: the project manager, the lead discipline engineers, the commissioning manager. Chinese EPC contractors respond with CVs that reflect the best available personnel for that project designation. Whether those personnel will actually be assigned to the project is a separate question.
The more useful evaluation asks for the proposed engineering team structure, the number of engineers proposed for each discipline, their years of experience in the specific process technology being deployed, and the names and CVs of the commissioning team -- not just the commissioning manager, but the engineers who will be at the plant during the commissioning period. This information, combined with a question about what process simulation tools and methods will be used during detailed engineering, provides a more accurate picture of what the engineering capability actually is.
The eleven-month commissioning overrun at the Central Asian gas plant cost approximately 1.8 times the original engineering budget in external consultant fees and extended owner team presence. The total cost recovery against the 28% EPC price saving was negative within the first year of operations -- before the long-term consequences of the thin detailed engineering were fully visible in the plant's operating performance. Whether your EPC evaluation process is capable of distinguishing engineering depth from engineering headcount is a question that becomes answerable only after commissioning, when it is too late to change the answer.
