5) Probe methodology across the lifecycle
Strong completions partners support the whole lifecycle, from consultancy to execution:
- Consultancy & planning: readiness reviews, boundary drawings, tag and systemisation strategy, and a resourced completions estimate aligned to the level-3 schedule.
- Pre-commissioning: discipline-specific ITRs, preservation management, vendor FAT uptake, and early energisation strategy.
- Commissioning & performance tests: subsystem handover gates, temporary works management, and cause-and-effect verification.
- Operations readiness: spares, maintenance plans, and control room training to ensure a clean handover.
Ask for their standard Completions Execution Plan table of contents, RACI, and sample ITRs. If their methodology can’t show how they minimise rework and compress the critical path, you’ll feel it during start-up.
6) Validate resourcing depth and global mobility
The best methodology fails without the right people in the right place at the right time. Test each firm’s ability to mobilise multi-discipline teams – mechanical, electrical, instrumentation & controls, HVAC, and process – across multiple time zones. What is their average time-to-mobilise? Can they accelerate and adapt for shutdowns, complex SIMOPS management, and offshore campaigns?
Backed by the Orion Group network, we provide global resourcing, competency-assessed and individual behaviours of personnel evaluated through psychometric testing at scale, supported by field-proven supervisors and data administrators. That blend keeps execution safe and stable while your project ramps.
7) Confirm governance, reporting and commercial fit
Finally, align on how you see progress and manage change. Effective completions management consultancy companies offer transparent KPIs: subsystem MC/CC curves, ITR pass rates, RFSU forecast, and ageing punch analysis. Governance should include weekly look-ahead, interface risk reviews, and formal change control tied to the schedule.
Commercially, choose the model that aligns behaviours: lump-sum for defined packages, T&M with performance bonuses for evolving scopes, or hybrid models linked to milestone handovers. Make sure digital licences, field devices, and travel/logistics are visible line items – surprises at site erode trust.
Why OCCMS?
We are a specialist completions and commissioning services provider with global reach, rooted in Orion Group expertise. Our teams deliver consultancy → pre-commissioning → commissioning → operations readiness across energy, renewables, built environment, life sciences, mining and defence. We combine experienced supervisors and engineers with Orbit® to provide live status, auditable sign-off, and rapid turnover dossiers.
What that means for you: safer execution, tighter schedule adherence, clean start-up, and fewer defects in early operations. Our track record includes multi-phase brownfield programmes with zero lost time incidents and on-time handovers, supported by robust governance and plain-English reporting. If you want a partner judged by outcomes, not slideware, we would like to talk.
