systementreprenad

Systementreprenad, or system contracting, is a procurement form in construction where a single contractor is contracted to deliver a defined technical system that meets specified performance requirements and interfaces. The client defines what the system must achieve and how it should connect with other parts of the project, while the system contractor designs, engineers, procures components from sub-suppliers, manufactures or assembles the system, and installs, tests, and hands over the system to the client. The contract places responsibility for system performance, integration, and often commissioning on the system contractor.

The scope is typically focused on a subsystem such as HVAC, electrical distribution, building automation, or other integrated installations. The system contractor coordinates the necessary sub-suppliers, ensures compatibility of components, and provides documentation, warranties, and service agreements for the system.

Compared with general contracting, where the main contractor coordinates multiple trades, or total contracting (design-and-build for the whole project), systementreprenad emphasizes a defined system with standardized modules and interfaces, reducing risk for the client in terms of performance and integration while transferring execution risk to the system contractor.

Benefits include defined interfaces, faster delivery, standardized components, and clearer responsibility for system performance. Risks include dependence on a single system supplier, potential reduced flexibility, and the need for precise interface definitions to avoid integration issues.
