Turnover & handover
Line lists, tag registers and drawing indexes handed over as data the owner can query, each entry traceable to the as-built drawing it came from.
- Works with
- Project engineers, completions teams and owner's representatives
- Starts from
- As-built drawings, registers and vendor data
- Delivers
- A handover package as connected, verified data
01
Summary
At handover, the owner receives thousands of documents and is expected to run a facility from them. Registers are assembled in spreadsheets at the end of the project, often by people who didn't build it, and the gaps show up years later, during a turnaround or an incident.
Operon builds the handover as the project goes: tags, lines and equipment read from the as-builts, verified, connected to their datasheets and vendor documents, and delivered as data. The owner gets a register they can query, with every entry traceable to the drawing behind it.

Inputs and outputs
What goes in
- As-built P&IDs, isometrics and layouts
- Equipment and instrument datasheets
- Vendor documentation
- The owner's handover specification
What comes out
- Tag, line and equipment registers in the owner's format
- Every entry linked to its as-built sheet and datasheet
- A gap list: tags without data, and data without tags
- A package the owner can query, not a folder of PDFs

Your team
01
Read the as-builts
Operon
Reads tags, lines and equipment from the as-built drawings into a verified register.
Your team
Confirms the items Operon routes for review.
02
Connect the documents
Operon
Links each tag to its datasheet, vendor documents and the revisions that changed it.
Your team
Points to where vendor data is kept.
03
Check against the handover spec
Operon
Measures completeness against the owner's requirements and lists the gaps.
Your team
Closes the gaps with vendors and the field.
04
Hand over
Operon
Exports in the owner's format and keeps every link intact.
Your team

Every entry traceable
Each register entry links to its as-built drawing and the document behind it.
The owner's spec as the checklist
Completeness is measured against what the owner asked for.
06
Getting started
Send the owner's handover specification and one system's as-builts. We build that system's registers and gap list so you can see the package before committing the project.
First results within a week. Live in three weeks.
- The owner's handover specification
- As-builts and datasheets for one system
- Any registers already assembled
