As buildings become more complicated, engineering evolves and building information modelling (BIM) becomes more widely used, the early engagement of a contractor is becoming much more important. In essence ECI is a form of negotiated tender but emphasis is put on the contractor as the lead designer from the outset of the project. This is beginning to be seen in infrastructure projects where the early appointment of a contractor can significantly affect the direction of the emerging design.
ECI involves the creation of a designer/contractor team led by the contractor. Methods to successfully achieve this are still in their infancy and, at present, methods of ECI are bespoke to a particular project. Contractor selection is similar to two-stage tendering as it is done not on a cost basis but rather on the quality of the team and bid. It is beyond the scope of this guidance note to address ECI in detail but readers should be aware of its uses and widening role in the industry.
