چکیده: Abstract: Electronic communications play an important role in assisting construction project managers. This paper presents original results about the quality of communication at construction sites in Iran, and evaluates the efficiency of electronic devices. To investigate the quality of communications in construction sites, a field study is conducted on a sample of 106 construction projects in Hamadan province. In this field study, civil and architectural engineers with executive or supervisory licenses from the Building Engineering System Organization of Hamadan Province are interviewed. A descriptive questionnaire with open-ended questions is designed. Cohen's kappa coefficient (k) is used to determine the percentage of agreement among the research participants. A case study was considered to evaluate the performance of automatic electronic communication in a construction site. The site is related to flour hives located in the west of Hamadan city. Five devices are used including QR Code tags, a GPS smartphone, electronic ckiosk, smartphone camera, and virtual reality building information model. For safety training, a video is used by the use of electronic ckiosk that shows the risks and injuries for people without helmets. Analytical hierarchy process is used to investigate the relative importance of electronic communication tools in the case study. The results show that most communications in construction sites are traditional (paper-based), inadequate communication between employees, and misunderstanding of requirements and agendas, and slow and ineffective communication are the most important communication problems of construction sites. The results also show that prioritizing the importance of electronic communication tools is the electronic kiosk, QR Code tags, smartphone camera, and GPS smartphone, respectively. In addition the results demonstrate the benefit of electronic communications on employee training, project safety, project time and project cost. Limited research has been conducted on the performance of electronic communications in construction projects. This paper will be of interest to those who work in the field of construction project automation. Key Words: Electronic Communication, Automation, Construction Site
