An engineer, procure and construct (EPC) contract is a form of D&B contract under which a design engineer or firm of design consultants heads a team which includes an experienced contractor and perhaps a plant supplier. The promoter specifies his project requirements in outline which the team designs in detail in continued liaison with him. The EPC organization arranges and manages construction, letting specialist work packages out as necessary to suitable sub-contractors. The promoter pays the actual cost of the work plus a fee, subject to a guaranteed maximum price, or to a target cost with an arrange- ment for the sharing of savings or excess costs on.
