Pre-startup safety review: arrive at the gate with everything already verified
Operational readiness is not a continuous drift toward Day 1. It is a series of formal decisions - each one a go/no-go that requires verified work across multiple scopes before it can be signed off.
CxPlanner structures every readiness gate - from Mechanical Completion Ready through pre startup safety review to Day 1 Go-Live - with configurable criteria, multi-party sign-off workflows, and a complete audit trail on every gate decision.

Gate reviews expose what the programme failed to track
Readiness gate reviews reveal the accumulated gaps of a programme that was not tracked in real time.
The PSSR checklist is assembled under pressure.
The pre startup safety review requires documentation from commissioning, training, and operations. When these workstreams are tracked separately, the PSSR checklist is compiled in the days before the review - from scattered sources, under deadline pressure.
Prerequisites from multiple scopes are invisible until the review.
A readiness gate requires sign-offs from commissioning, training, and documentation. When each scope tracks progress in its own system, the gate review is the first time the combined picture is visible - and gaps appear at the worst possible moment.
Waivers and conditional passes are tracked informally.
When a gate cannot be fully signed off, a conditional pass or waiver is agreed. Without a system to track open items against waivers, the audit trail breaks down - and the same issue appears at the next gate review.
Platform where prerequisites are tracked live and the gate review reflects reality
CxPlanner structures every readiness gate - from the first stage-gate milestone through to the final pre-startup safety review - with configurable criteria, multi-party sign-off requirements, and open item tracking set before the review.
The PSSR checklist is drawn from live programme data: commissioning sign-offs, training completions, documentation readiness. Outstanding prerequisites surface the day they become outstanding, not the day of the review. See the full operational readiness platform overview for how gates fit the rest of the programme.
Here is how it works
Configurable gate structure defined in the programme
Each gate - Mechanical Completion Ready, Cold Commissioning Complete, Hot Commissioning Ready, Pre-Startup Ready, Operator Handover Ready, Day 1 Go-Live - structured in CxPlanner with configurable criteria.
Prerequisites tracked across all contributing scopes
Commissioning sign-offs, training completions, and documentation deliverables tracked as gate prerequisites in real time - across all scopes, in one view.
Outstanding items surface automatically
A prerequisite that is overdue appears in the readiness gates dashboard the day it becomes overdue - not at the gate review.
Multi-party sign-off workflow managed in the platform
Gate decisions requiring sign-off from owner, operator, Cx team, and GC managed in CxPlanner - all parties in one workflow, all sign-offs documented and time-stamped.
Conditional passes and waivers tracked
When a gate is passed with open items, the waiver is documented in CxPlanner with the outstanding items tracked against it - so the next gate review starts from a clean record.
From first ORR milestone to pre-startup safety review - here is what CxPlanner covers
Configurable gates, live prerequisite tracking, multi-party sign-off, and complete audit trail.
The full gate sequence, configurable per project
CxPlanner supports the full gate sequence - Mechanical Completion Ready, Cold Commissioning Complete, Hot Commissioning Ready, Pre-Startup Ready, Operator Handover Ready, Day 1 Go-Live - with configurable criteria per gate and per industry.
Reflects the real state of the programme
The PSSR checklist is drawn from the actual commissioning, training, and documentation records in CxPlanner. It reflects the real state of the programme - not compiled separately from the work it is meant to verify.
What is complete, outstanding, and overdue
Gate prerequisites from commissioning, training, and documentation tracked in the same platform. The readiness gates dashboard shows what is complete, what is outstanding, and what is overdue - across all contributing scopes.
Every conditional pass documented and tracked
When a gate is passed with open items, the waiver is documented in CxPlanner with outstanding items tracked against it. The pre startup safety review audit trail includes every conditional pass and every open item closure.
A complete, time-stamped record per system
Every gate decision documented and time-stamped. Gate history per system. "Days to next gate" forecasting based on current pace. Integration with scheduling - gate dates as anchor points.
Key benefits from tracking readiness gates in CxPlanner
Gate reviews confirm what the programme has already demonstrated - not discover what it failed to complete.
Outstanding prerequisites surface before the review.
A prerequisite that cannot be met by the gate date appears in the readiness gates dashboard weeks before the review. The team has time to close it - not hours to work around it.
The PSSR checklist is complete before the review begins.
The PSSR checklist is built from live programme data throughout the project. By the day of the review, it reflects the actual state of commissioning, training, and documentation - not what was assembled the night before.
The audit trail is complete at every gate.
Every readiness gate sign-off is documented and time-stamped in CxPlanner. At handover, the complete gate history - from the first milestone to the pre-startup safety review - is part of the programme record.

What readiness gates does CxPlanner support?
CxPlanner supports a configurable gate sequence - Mechanical Completion Ready, Cold Commissioning Complete, Hot Commissioning Ready, Pre-Startup Ready, Operator Handover Ready, Day 1 Go-Live - and project-specific milestones. Gate criteria are configurable per gate and per industry. Pre-built gate templates per industry may be available.
How does CxPlanner structure the PSSR checklist?
The PSSR checklist in CxPlanner is drawn from the actual commissioning, training, and documentation records accumulated throughout the programme. It reflects the real state of the programme - not a document compiled separately from the work it is meant to verify.
Does CxPlanner support conditional gate passes and waivers?
Conditional passes with open items tracked against them are part of the readiness gates functionality.
How far in advance does CxPlanner surface outstanding gate prerequisites?
Outstanding prerequisites appear in the readiness gates dashboard the day they become overdue - not at the gate review. The team sees the gap as soon as it appears, with enough time to address it before the review.
