Turnover

In Plain English

The formal handover of the completed building to the owner, including documents, keys, and system training.

Definition

Turnover is the process of formally transferring a completed building or facility from the contractor to the owner at project closeout. It includes delivering all keys, access cards, as-built drawings, O&M manuals, equipment warranties, spare parts, and attic stock, and conducting training for the owner's operations and maintenance staff on all building systems.

Why It Matters in Bidding

Turnover deliverables represent real cost and labor that estimators often underprice, including assembling O&M manuals, compiling as-builts, gathering warranties, and scheduling owner training. Building these requirements into the bid and the schedule protects final payment and retainage release, since owners commonly withhold closeout funds until the turnover package is complete and accepted.

Example

Approaching substantial completion, the GC's project manager assembles the closeout binder—warranties, attic stock, as-builts, and equipment O&M manuals—and schedules HVAC and controls training for the owner's maintenance staff before requesting release of retainage.

Frequently Asked Questions

A complete package typically includes as-built drawings, operation and maintenance manuals, equipment warranties, keys and access devices, spare parts and attic stock, testing and balancing reports, and documentation of owner training. The specific requirements are listed in the closeout specification, so bidders should review them to price the effort accurately.
Owners frequently tie final payment and retainage release to acceptance of the turnover deliverables. Incomplete manuals, missing warranties, or unscheduled training can delay closeout for weeks. Treating turnover as a tracked deliverable with assigned responsibility and cost helps the contractor protect cash flow at the most margin-sensitive point of the job.
No. Substantial completion means the owner can occupy and use the building for its intended purpose, while turnover is the formal administrative handover of documents, keys, training, and remaining items. Turnover activities often overlap with the punch list period and continue through final completion and closeout.
