These approaches are variations of DB and DBOM, respectively, except that the DB or DBOM team provides some or all of the project financing. The potential benefits of the DBF or DBFO approaches are the same as those under the DB and DBOM approaches and also include the transfer of the financial risks to the design-builder during the contract period. While the project sponsor retains ownership of the facility, the DBF and DBFO approaches attract private financing for the project that can be repaid with revenues generated during the facility's operation.
