The design-build-operate-maintain (

The design-build-operate-maintain (DBOM) model is an integrated partnership that combines the design and construction responsibilities of design-build procurements with operations and maintenance. These project components are procured from the private sector in a single contract with financing secured by the public sector. This project delivery approach is also known by a number of different names, including "turnkey" procurement and build-operate-transfer (BOT).
