Handing the finished project to the service department: the warranty handover package
A service technician receives a call about equipment on a recently completed project. The project manager is away, the owner names a room differently from the drawings, and the technician cannot find the commissioning or warranty records. The team starts by asking questions already answered during closeout.

Hand the finished project to the service department with a practical warranty package and a walk-through of the systems and remaining issues. Include owner contacts, verified warranty dates and obligations, subcontract contacts, equipment identifiers, record locations and open-item owners. Separate confirmed information from anything still being checked. The service team needs a usable route from a call to the relevant asset and responsible person, not only a folder of closeout documents.
Make the service handover usable on the first call
- Name the service and customer contacts. Record the owner’s normal and urgent contact routes, access arrangements and company service lead. Confirm who receives a request and who can authorize work or escalate an uncertain obligation.
- Verify the applicable warranty information. Identify the agreement or manufacturer record supporting each system’s start, end and conditions. Have the responsible commercial or technical person confirm uncertain dates; do not apply one assumed period to every component.
- Connect assets to records. Include equipment model and serial details where relevant, room or system names and the locations of as-builts, manuals and commissioning information. Test that the service team can actually open the referenced files.
- Identify the trade obligations and contacts. Link the relevant subcontract or service responsibility with a current contact. Distinguish an assigned obligation from a telephone number that merely happens to be in the project directory.
- Expose open items and known recurring concerns. Record their locations, current status, previous actions and responsible owners. Keep an observation factual; do not describe a suspected cause as a confirmed diagnosis or a promise of warranty coverage.
- Walk the package with the service team. Book a one-hour handover visit to locate equipment, review access and demonstrate how a request reaches its supporting record. Adjust the visit and arrange follow-up where the systems need more time. Finish with the missing information, owners and follow-up dates.

Check your understanding
The owner calls a room by an informal name that does not appear on the drawing. What should the handover preserve?
