Information and Communications Technology in Construction: A Proposal for Identifying the Root Causes of CPI

To improve feedback from the Cost Performance Index (CPI), it is necessary to identify the reasons why Actual Cost differs from Planned Cost. At present, this information is collected and transferred orally, on paper, by telephone or e-mail. This paper proposes an information and communication technology that uploads information to an Intranet using electronic devices and mobile applications, thus encouraging the participation of workers and other stakeholders. This proposal aims to contribute towards information quality improvement in Production Control.
