Your Details



The NEC4 Design Build and Operate Contract (DBO) has been developed for the appointment of a contractor to operate a client’s asset for a period of time, and during that period undertake significant new build or refurbishment to support the operational requirements.

It combines and places responsibility for usually disparate functions (design, construction, operation or maintenance) with a single supplier.

People will be motivated to play their part in collaborative management if it is in their commercial and professional interest to do so. Uncertainty about what is to be done and the corresponding risks and liabilities can lead to disputes and confrontation.

The DBO clearly allocates risks, and the collaborative approach will reduce those risks and uncertainty for all the parties.
