oplever

Oplever is a Dutch verb meaning to deliver, hand over, or produce. It is commonly used in the sense of completing a project and transferring it to a client, owner, or user. The related noun is oplevering, referring to the act or event of delivery and completion.

In practical contexts, oplevering often marks an important milestone. In construction and real estate, the term denotes that a building or property is ready for use and possession is transferred, typically after an inspection and acceptance by the client. The process usually includes an opleveringsinspectie (handover inspection), an opleveringsrapport (handover report), and a list of defects or outstanding works (gebrekenlijst) that must be remedied within a defect liability period. Acceptance criteria and formal signing off are common elements to finalize the handover.

In IT, manufacturing, and procurement, oplevering describes delivering a product or software to the customer. Milestones use terms such as opgeleverd (delivered) and acceptatie (acceptance), with criteria defined in the contract or project plan. The concept similarly implies that the deliverables meet specified requirements before formal transfer.

Etymologically, oplever originates from leveren (to deliver) with the prefix op-, forming a separable verb. The normal legal and professional usage emphasizes completion, transfer of rights or possession, and the responsibility for post-delivery issues during the defect liability period. Related terms include opleveringsdatum, opleveringsrapport, and opleveringsinspectie.
