In the design, build and operate (DBO) approach, the client hires a D&B firm to construct and subsequently manage and operate the project, such as in the case of a wastewater treatment facility. This is generally considered a “turn-key” project - starting from project concept and carried through to full scale operation. Two different approaches have been taken:
- a long-term management scheme; or
- a short-term “startup” contract that transfers the operation back to the client or a public entity.
Short–term contracts may range from 1 to 2 years, whereas long-term contracts can typically last for at-least 5 to 7 years. Short-term DBO contacts are commonly used to make sure the plant is operational, meets the regulatory requirements, and provides the client or public entity time to become trained on the operation and maintenance of the new facility, before the facility is transferred back to the client for long-term O&M.
After the initial contract period the client and DBO will review and commonly renegotiate the terms of the operational contract, or the client may elect to go out for competitive bid for these services. However, in some instances the DBO may design and build a project that employs a proprietary technology that secures them copy-righted license agreements for the long-term operation and maintenance of the facilities.
