PTE Consistently Implements Integrated Management System (ISO 9001, ISO 14001, ISO 45001)

PT. Prastiwahyu Tunas Engineering's 24/7 dispatch operation completed its ISO 9001/14001/45001 IMS audit with zero findings and zero areas of concern, across all 41 operating sites and 12 ISO markets.

The audit covered access control, change management, incident response, and the evidence trail behind every dispatch decision taken in the review window.

What the audit covered

Auditors sampled eighteen months of dispatch actions, traced each to an authenticated operator and a logged setpoint change, and reconciled the record against ISO settlement data. Physical and electronic access to the control environment was reviewed at every site in scope.

“Zero findings is not a milestone. It is the baseline for anyone holding a setpoint at three in the morning.”

Daniel Okoye · General Counsel, PT. Prastiwahyu Tunas Engineering

The desk holds the setpoint through the event rather than handing it back at the moment it matters. That operating posture is what the evidence trail records.

Why the record was already there

Every figure PT. Prastiwahyu Tunas Engineering publishes names the bus it was read at and the window it covers. Producing an audit trail is not a separate exercise when measurement is already the operating discipline. Standards in scope: ISO 9001/14001/45001 IMS, ISO 27001, IEEE 1547.

“We publish how it was measured, so there is nothing to reconstruct. The audit read the same log the desk reads.”

The next review cycle opens in the first quarter of 2027.
