SYSTEMS COMPLETION AND TURNOVER

Completions Software for Capital Projects

ONComplete brings systems, check sheets, punch lists and turnover readiness into the same platform your teams use to plan and build, so commissioning starts sooner and handover happens with confidence.

A FULL COMPLETIONS SOLUTION

Connect Construction and Commissioning in One System

ONComplete is completions software built for owners, EPCs and contractors who need to carry a project from mechanical completion through commissioning and startup. On most projects, completions runs in a separate tool from construction, and the handoff between the two is where turnover dates slip. ONComplete keeps systems, subsystems, tags, check sheets and punch items alongside the installation work packages that feed them, so your completions and commissioning teams always know what is finished, what is holding up a system and how much testing is left. Because it runs on the same O3 platform your planners and field crews already use, there is no separate database to reconcile and no export to chase before a turnover meeting.

  • Owners, EPCs and contractors working from one completions record in a modern SaaS environment
  • Graphical definition and status of systems, subsystems, test packages and turnover packages
  • Check sheets and ITRs generated at the tag level and assigned automatically by rules you set
  • Walkdowns and punch items tied to the systems and work packages they affect
  • Readiness forecasting and approvals, connected to any system through OOTB integrations or enterprise REST APIs

Unlock the Power of ONComplete

A full completions solution that shows readiness clearly, from the first installed tag to final handover.
THE ONCOMPLETE ADVANTAGE

Deliver Projects on Time and on Budget

Start testing a system as soon as it is ready, rather than waiting for every work package around it to close.

  • Tag-level predecessor logic that clears a constraint once the tags a system needs are complete, even while the rest of the IWP is still in progress
  • Dedicated test and turnover work packages planned with the same constraint management your construction teams already use
  • Punch items captured, assigned and closed before they turn into late-stage scope

Increase Project Visibility

Know where every system stands and how much testing effort remains before you commit to a handover date.

  • Status visualization of systems, test packages and turnover packages in 3D or list views
  • Check sheet norms that roll up estimated testing hours by tag, subsystem and system
  • Automated relationships between Installation Work Packages (IWPs), Test Work Packages (TWPs) and systems
  • A full audit trail from installation through final sign-off

Drive Positive Accountability

Give every check sheet, walkdown and punch item a clear owner, and let O3 handle the administrative work that slows completions teams down.

  • Rules-based assignment of check sheets to tags by discipline and object type, so no one has to build that matrix by hand
  • Configurable workflows, approvals and sign-offs for every certificate and package
  • Completed check sheets captured from the field and progressed in a single step

CUSTOMER STORY

How a Global EPC Turned "Ready Enough" Into Truly Ready

On the first phase of a major greenfield facility, this EPC tracked completions readiness in spreadsheets and static dashboards that went stale within days, while fabrication and material status sat in separate silos and subsystem handovers slipped out of sequence. For phase two, the team brought system and subsystem hierarchies into the same O3 view as construction, tracking fabrication by spool and package, material readiness from enterprise systems and field progress during installation, all visible in the 3D model and in role-based dashboards.

  • Subsystem and system readiness tied directly to live construction data
  • Fabrication, material and field progress in one view instead of three
  • Confidence that 95% complete on the schedule means ready to hand over
Read the Case Study
Global EPC team using live completions data to confirm system readiness on a greenfield capital project

We explored various solutions, but the decision was made to leverage the highly customizable system configurations and user flexibility that O3 brings to the table.

Constraint management in O3 gives us the ability to oversee the planning process and to get ahead of issues prior to work beginning.
Having the interface management functionality in the project through O3 has been a significant contribution. It allows us to record and monitor interface points and key agreements, improving traceability and reducing communication risks between parties.
More traditional thinking might suggest that data and processes need to be in a mature state prior to engaging or using a system or tool, however, O3’s flexibility and collaborative approach has enabled us to move forward along our continuous improvement journey together.
COMPLETIONS SOFTWARE FAQ

Questions About Completions Software

What completions and commissioning teams ask most when they evaluate ONComplete.

Request a Demo
What is completions software?

Completions software tracks the work needed to prove a system is built, tested and ready to hand over. It organizes a project into systems and subsystems, links each tag to the check sheets and ITRs it needs, records walkdowns and punch items, and manages certificates and approvals through mechanical completion, commissioning and turnover.

How is ONComplete different from a standalone completions tool?

Standalone tools keep completions data in a separate database that has to be reconciled with construction progress. ONComplete runs on the same O3 platform as your installation work packages, so a system's readiness reflects field progress as soon as it is recorded, and testing can start once the tags a system needs are complete.

Can I use O3 for completions if we didn't use it for construction?

Yes. ONComplete works as a full completions solution on its own, even when construction was planned and tracked in another system. O3 integrates with any system seamlessly through OOTB integrations or enterprise REST APIs, so your systems, tags, installation progress, schedule and documents flow into ONComplete from the tools already on the project. Your completions team gets the same live view of readiness without asking construction to change how they work.

How does ONComplete fit with Advanced Work Packaging?

ONComplete carries AWP past construction with dedicated Test Work Packages and turnover packages. Systems link automatically to the IWPs that install them, which keeps the path of construction and the commissioning sequence aligned.

Does ONComplete work with the commissioning and document control tools we already use?

Yes. O3 integrates with any system seamlessly through OOTB integrations or enterprise REST APIs, so you can connect your existing commissioning, document control and CMMS tools or run completions entirely in ONComplete.

Who uses a completions solution like ONComplete?

Completions managers, commissioning leads, construction managers and owner project teams use ONComplete to plan testing, clear punch items, track certificates and agree on when each system is ready for handover.

ENSURE PROJECT SUCCESS

Drive Success with Seamless Project Handoffs

Separate completions tools, spreadsheets and late punch lists push startup dates out. ONComplete gives your completions, commissioning and construction teams one source of truth for turnover.
