ABSTRACT
The dismal performance of the global construction industry has been a major source of worry for practitioners and construction stakeholders. The Nigerian Construction industry (NCI) has not been immune from these problems also as it is plagued with project abandonment, poor project analysis and management, poor quality of work, adversarial relationship, litigation amongst others. Integrated project delivery (IPD) is a relatively new project delivery approach which serves as a response to the poor performance of the construction industry as regards failure of projects achieving desired outcomes such as cost and time overrun. IPD is influenced by the extensive collaboration with emphasis on the exploitation of relevant technologies and lean construction for continuous improvement in project delivery. The study investigated the possibility of adopting IPD concepts and principles in the NCI with the view to addressing some of the pertinent problems of the industry such as wastes and adversarial relationships. 87 being a sum of the population were administered questionnaire of which 75 duly filled and returned questionnaires were used in the analysis. The analysis were presented in tables where they were ranked using relative importance index. Lack of awareness of the concept of IPD with a RII of 0.70 ranked as the major barrier to the adoption of the concept. Respondents indicated collaborative decision making with a RII of 0.71 and which is one of the characteristics of IPD was relevant in improving project delivery. The study concluded that awareness of the concept of IPD was relatively low and recommended the propagation of the concept by professional bodies through inter - professional workshop and symposia as a way of dissemination and diffusion of awareness of the concept which would assist to create and encourage further research to its adoption.
