The current problem is that the process of managing data about the progress of project work and managing project financial data cannot be done properly because the data recording is done on paper media and is not well coordinated. This has an impact on the difficulty of project owners and project consultants in controlling project work. The purpose of this research is to analyse how the current project work control process is and to design an information system to optimize project work control. In developing this system, researchers used the prototype method, starting with gathering system requirements, building mock-up, and testing by users. The results of this research are web-based project management information system design that can manage and control project work and project financial data. All documents can be directly uploaded to the information system thereby minimizing document loss. The process of financial control both project expenses and revenue is much better because it can be monitored more closely and thoroughly so as to reduce fraud. Project activities can work better because of computerized working time monitoring and better control if there are delays in work. This research provides an overview of project management information systems that can be used to manage construction projects.
