Owner's engineering that represents only the owner.

A drop-in, independent owner-side engineering team for polysilicon plants — from licensor selection through first-qualified output.

Owner's engineering, the way it should work

A full team sitting on the owner's side of the table — for the full life of the project.

Most polysilicon projects need an owner's engineering team because the owner's internal staff was never built to review a licensor package, police an EPC, and run commissioning on a high-purity chemistry plant — all at the same time. NEXARSiL provides that team as a drop-in capability. We represent only the owner, we have no commercial tie to any licensor or EPC, and we stay on the project from FEED through first-qualified output.

The value of real owner's engineering is not in producing documents. It's in catching the small decisions that quietly cost a plant years of yield: the reactor internal that was value-engineered out of the package, the TCS distillation column that was reduced by one stage, the cleanliness specification that was downgraded on a single weld class, the instrument that was moved to save pipe. None of these show up in a board report. All of them show up in purity data two years into operation.

NEXARSiL's owner's engineering team has lived through those exact situations inside real plants. That's what we bring.

Scope of owner's engineering

Twelve areas we cover on a typical program.

AreaWhat we do
Licensor interfaceRepresent the owner in all technical discussions with the licensor, from FEED kick-off through final handover.
Package reviewIndependent review of the licensor technology package — P&IDs, datasheets, reactor internals, control philosophy.
EPC selectionSupport the owner in EPC tendering, bid evaluation, and contract negotiation.
Design reviewEngineering review of every EPC design deliverable with a high-purity lens.
SpecificationsHigh-purity specifications for welding, passivation, cleanliness, lubricants, sealants, and packaging.
ProcurementTechnical support for long-lead equipment, critical valves, instruments, and reactor components.
Construction QA/QCOn-site construction quality and cleanliness oversight during execution.
Pre-commissioningLoop checks, line flushes, pressure tests, and high-purity clean-up before first chemicals.
CommissioningOn-site commissioning team for first HCl, first TCS, first CVD deposition.
Start-upSupport through first-qualified output, purity ramp, and performance test runs.
TrainingOperator training built around this specific plant, not a generic polysilicon course.
HandoverIndependent assessment of readiness for operational handover to the owner's staff.
Independence — how the firewall works

Why our technology package does not compromise our owner's engineering.

NEXARSiL offers both a licensed technology package and owner's engineering. On any owner's-engineering engagement, a strict internal firewall separates the two roles: different team leads, different data environments, and a written disclosure to the owner of the policy and controls. When NEXARSiL is in the owner's-engineering role, we have no commercial interest in which licensor is chosen or how much equipment is purchased from which vendor.

Who uses owner's engineering

First-time polysilicon owners

Organizations building their first polysilicon plant who need an experienced owner-side engineering capability before the licensor kicks off FEED.

Existing producers expanding

Owners adding a new train or converting a line and need independent oversight of the EPC and licensor.

Investors with operating control

Private equity or development-finance owners who want an engineering team they control, not one funded through the EPC.

Government-sponsored projects

National programs that need independent technical oversight separated from the commercial parties.

Frequently asked

Questions we often get about this

Can you act as owner's engineer if the owner has already selected a licensor?

Yes — this is the most common engagement pattern. We step in after licensor selection and represent the owner through FEED, EPC selection, detailed design, construction, commissioning, and first-qualified output.

How is owner's engineering priced?

Typically a combination of a scope-based engagement fee and on-site presence during execution. We right-size the team to the phase: heavier during FEED and commissioning, lighter during procurement and fabrication.

What if the licensor package has serious design issues?

We raise them in writing, with specific clause references and proposed engineering resolutions, and we escalate through the contractual mechanisms the owner has with the licensor. We don't paper over design problems to protect commercial relationships.

Do you stay through purity ramp-up or leave at mechanical completion?

We stay through first-qualified output. Mechanical completion is a contract milestone; qualified output is the real one.
