Turnkey EPC & Design–Build
One delivery framework, with clear boundaries.
Turnkey delivery needs a shared understanding of what the system must do and where each party’s responsibilities begin and end.
Where this service helps
Turnkey delivery needs a shared understanding of what the system must do and where each party’s responsibilities begin and end.
The situation to resolve
Scope gaps between design, procurement and site work can surface late when interfaces are left undefined.
Splitting a plant across a designer, a civil contractor, an equipment supplier and an automation vendor leaves gaps between them, and the client is left to fill them.
Under turnkey EPC, one contract covers everything from survey to a running, monitored plant.

Questions before the next step
Does turnkey mean every site activity is included?
No. The accepted scope defines civil works, utilities, supply, permits, testing and third-party responsibilities.
How is the service scope finalised?
The accepted proposal records deliverables, responsibilities, exclusions, acceptance requirements and commercial terms.
How is turnkey different from design & build?
Under design & build you handle the civil works. Under turnkey EPC they are ours, along with automation, monitoring, handover and training.
Who runs the plant after handover?
Your own operators, trained at handover, or our team under a Zeal-Care O&M contract.
