Tracking construction projects progress using mobile hand-held devices Marzouk, Mohamed M.; Zaher, Mohamed M.
Recent studies have attempted to automate monitoring progress of construction projects using 3D laser scanning or image based reconstruction methods. This paper presents a new methodology for monitoring using mobile hand-held devices such as smartphones and tablet computers. This is done by proposing a new developed android application called “BIM track” that the end-user can use to record the progress of activities (actual dates, percentage complete, and actual cost) from a remote location. BIM track is cloud-based which ads in speeding up the production of construction progress reports and improves data accuracy as it’s connected with Google drive using fusion tables that make the user able to combine/edit the data on the internet. As such, it is capable to collaborate, visualize, and share data through the internet to export the results into an Excel spreadsheet from the mobile application to a remote computer. In addition, the data can be imported to the Navisworks to update the project’s 5D model. Accordingly, time schedules, cost performance (CPI) and schedule performance index (SPI) can be calculated easily. In addition, such results can be shown in 5D model using Navisworks to compare actual progress versus the planned progress. BIM track android application can have an access to any uploaded project’s 3D model using Autodesk 360 as this application is integrated with BIM track. A case study is presented below to demonstrate the use of the proposed methods to track the project and to make a comparison between the actual and the planned progress of the project.
