Advanced technologies are increasingly being introduced to the construction industry. Several studies in the literature have examined the diffusion of advanced technologies such as communication technology; however, the diffusion process for hard construction technologies such as advanced concrete pumps, from an organizational diffusion perspective, has received very little attention. Moreover, project managers require an approach by which they can take the complexities within the construction industry into account. This paper presents a Dynamics of Technology Adoption Model (DTAM) which is based on the concept of system dynamics incorporating time lags for each activity, operation feedback effects and causal links among factors. The model demonstrates the relationships between different attributes such as individual, financial and technological factors in a visual context, in order to evaluate the diffusion patterns of advanced concrete pump technologies. The model is verified using the results of a survey of practitioners in the US and Australia. Finally, the paper discusses the implications of the model structure for fostering pump concrete diffusion, as a means of boosting productivity in building construction.
