Several aspects of change to the procedures in the construction delivery process have been described in recent times, particularly those affecting building procurement systems. This paper describes the results of an investigation into one of the underlying causes of such change, particularly that which is affecting the traditional roles of the various parties that participate in the construction procurement process. It is proposed that one of the 'agents' of change is the product of tertiary education programmes that have been producing 'professional builders'. It describes how a new generation of builders, equipped with business skills and an inherent dissatisfaction with the traditional structure and procedures of the industry, are allowing leading construction companies to develop innovative construction marketing strategies and systems. These systems are based upon sound business practice, offer improved customer satisfaction and allow them to get closer to customers. In so doing they are taking over the roles of various built environment consultants who were principal agents and leaders in the traditional building procurement system.
