Industries we support
Independent completion governance across complex capital project environments requiring system-based verification and controlled commissioning readiness.
Applicable across offshore, onshore, and infrastructure developments.
Proofdatum leads with offshore oil and gas completion depth. The method transfers because it is built on facility systems, evidence and gate discipline rather than on any one sector’s conventions: wherever handover must be proven rather than presumed, the same controls apply.
Across complex capital projects, construction progress alone does not guarantee system readiness. Proofdatum applies a consistent completion governance approach across sectors, adapted to each project’s scale, interface complexity, and operational risk profile.

One control model, from foundation to governance
Five integrated layers take a project from physical system control to executive-level assurance. Each layer builds on verified evidence from the layer beneath it, so readiness at handover is demonstrated, not assumed.
- Subsystem-based verification over discipline progress
- Verified evidence over reported percent complete
- Independent assurance over self-assessment
One model. Every system.
Assured readiness at handover.

Physical System Control
Where completion risk typically emerges
We add value at critical handover points, when readiness gaps can impact cost, schedule and performance.
Late Construction Phase
We identify readiness gaps early and align execution to reduce rework and late-stage risk.
Mechanical Completion
We verify system integrity and documentation to establish a reliable handover baseline.
Pre-Commissioning
We verify that pre-commissioning activities are complete and evidenced before systems are offered to commissioning.
Commissioning & Start-Up
We keep completion governance live through commissioning and start-up: controlled punch deferrals, accepted exceptions and a defensible evidence trail through to sustained operation.
When subsystem readiness is unclear, schedule confidence becomes exposure.
