Construction project management is the application of knowledge, skills, tools and techniques related to project activities achieving the project requirements. Accurate and timely acquisition of the site data and information could improve the project management decision processes. However, obtaining the data and information in minimum possible time is the complex process due to nature of the construction site condition. There are several limitations with regards to the site data acquisition including, monitoring construction site, and sharing a daily status report. This study investigates the potential of using smartphone as a new technology in construction sites: (1) to improve monitoring and controlling the site activities; (2) to accelerate decisions making process by improving the speed and accuracy of information exchange process. This study provides an overview of the feasibility of using smartphones in three areas of project management knowledge, discussed in a Guide to the Project Management Body of Knowledge (PMBOK), including time management, quality management and human resources management. Validation was conducted through the real case study based on the proposed scenarios. Return of investment and sensitivity analysis of the two scenarios were also compared to find the efficient scenario. The results of this study can be applied to improve the monitoring and understanding of the site status and can potentially facilitate the decision making process.
