How we work
Built for projects where construction completion does not guarantee readiness.
We support owners and EPCs in high-complexity project environments. Our method holds across project scale, system complexity, execution maturity and operational risk.
Our working method
Four stages that keep completion risk visible and controlled, from planning through to handover.
Plan & prepare
Define scope, systems, boundaries, stakeholders and completion strategy. Establish the baselines, interfaces, readiness criteria and governance controls required for execution.
Execute & control
Monitor completion progress, punch exposure, document readiness and schedule alignment. Identify blockers early and drive accountable resolution across disciplines and contractors.
Verify & validate
Apply system-based assurance through completed Inspection and Test Records (ITRs), their supporting proof records, punch status and physical walkdowns. Confirm readiness before handover decisions are made.
Complete & handover
Control handover to commissioning and operations with complete records, accepted exceptions, clear ownership and readiness confidence.
Our operating principles
Five principles applied on every engagement.
Risk-focused
Completion risk is identified, prioritised, controlled and escalated before it impacts handover or start-up.
System-based
Work is structured around systems, subsystems, interfaces, boundaries and readiness dependencies.
Evidence-driven
Decisions are based on ITRs, punch status, dossier maturity and traceable completion data.
Collaborative
Owners, EPCs, contractors, vendors and commissioning teams work from aligned responsibilities and transparent priorities.
Commissioning-ready
The outcome is not just construction completion, but safe, controlled and verifiable readiness for commissioning and start-up.
How CompleCore™ governs project completion
One control model, from foundation to governance.
01
Physical System Control
Define and control systems, subsystems, boundaries, tag allocation and ownership.
02
Completion Verification
Track ITR completion, punch status, mechanical completion and RFC evidence.
03
Documentation Integrity
Ensure completion records, handover packs, evidence traceability and audit readiness.
04
Schedule Integration
Link completion progress to schedule logic, sequences, readiness and risk visibility.
Executive Governance & Risk Escalation
Schedule integration
Completion evidence inputs
- System / subsystem status
- ITR completion
- Punch exposure
- Dossier maturity
- Preservation status
- Walkdown readiness
Project control outputs
- MC skyline confidence
- Commissioning readiness sequence
- Critical subsystem blockers
- Handover risk forecast
- Executive escalation priorities
What clients can expect
Clear subsystem readiness visibility
A transparent view of what is complete, incomplete, blocked or not yet verified across all systems and subsystems.
Earlier identification of handover risk
Punch, documentation, system-boundary and schedule-readiness issues identified before handover pressure peaks.
Controlled Mechanical Completion & handover
MC and handover decisions supported by objective evidence and agreed acceptance criteria.
Decision-grade executive reporting
Clear escalation of readiness constraints, recovery priorities and commissioning-impact risks for confident decisions.
How we engage
Three ways to bring Proofdatum in, matched to where your project stands: a fixed ten-day assessment, embedded completion control through delivery, or intervention when handover is already at risk.
Rapid Completion Assessment
Ten-day independent diagnostic
- Completion risk assessment
- PCMS maturity review
- Handover gap analysis
- Executive recommendations
Completion Control Deployment
Embedded completion governance through delivery
- Subsystem readiness tracking
- Punch and dossier governance
- MC / commissioning interface support
- Weekly risk and readiness reporting
- Team enablement and completions training
Handover Recovery
Executive-level intervention when handover is at risk
- Independent readiness reset and ranked recovery plan
- Interface escalation and control
- Punch and certification surge to closure
- A defensible handover position restored
When to bring us in
Completion risk is cheapest to remove at the start of a project and most expensive at the end.
We make sure the processes, procedures, tools and training are ready before construction needs them.Mid-build
We verify progress and raise delay signals while recovery options are still open.Late
The later control arrives, the more the outcome depends on rework, task forces and negotiation.
FEED & Detailed Engineering
Design completion in
Completion strategy, PCMS structure and the evidence architecture set before construction: tag registers, ITR allocation, certification model and handover boundaries. Procedures, tools and team training ready to run from day one, with independent governance established at the point of maximum leverage.
Construction Completion
Control the build-up
Completion control in place as equipment, piping and cabling begin installation, with construction priorities aligned to commissioning requirements. Completion evidence verified as workfronts complete, and delay signals raised early so recovery plans are made while options are still open.
Mechanical Completion
Prove the turnover
Internal line walks that find defects and missing items before the formal walkdowns with the handing-over and receiving parties, with walkdown packages complete and invitations issued on time. A completion control room carried through from construction keeps findings resolved, while MC verification, certification integrity and punch discipline keep subsystems flowing to handover.
Pre-Commissioning
Hold the gates
RFC readiness verified on evidence rather than assertion, with punch and certification surge control as volumes rise, and the defects that surface at this stage tracked and closed before they stall the gates: flange management, preservation, Ex inspection gaps, cleanliness and temporary isolations left in place.
Commissioning
Defend the handover
RFSU readiness and dossier integrity proven gate by gate. Carry-over work on subsystems already handed over is sequenced and closed to committed dates, so construction completes without disrupting the commissioning sequence. Exceptions controlled rather than accumulated, with executive-level intervention where handover is at risk.
Ready for Start-Up & Operations
Hand over evidence, not assumptions
A defensible handover position for the Receiving Party: complete dossiers, controlled punch and verified readiness for start-up and operations.
Where you enter is flexible: a Rapid Completion Assessment gives an independent baseline in ten days at any phase, Completion Control Deployment carries governance through delivery, and Handover Recovery intervenes when dates are already at risk.
We work inside your existing team, tools and completion system; we do not replace them.
