Information and communication technology (ICT) has been identified as key to enhancing information processing in construction. However, the use of ICT is not always effective due to individuals’ resistance to use the ICT. Effective technology use is the interaction of three elements: the competencies and motivations of users, the nature and purpose of technology, and the characteristics of tasks. This research positions task requirements at the center of person-task-technology interaction. Both individuals’ capability and technology’s functionality need to fit task requirements. The aim of this research is to explore the influence of task-technology fit and person- task fit on individuals’ ICT adoption behavior. This research extends the traditional task-technology fit model by combing it with the construct of person-task fit from person-environment fit theory. The research model proposes that both individuals’ capability and technology’s functionality to carry out the task are crucial in ICT adoption. ICT managers should not overlook human factors during ICT implementation.
