Construction site safety is challenged by increased complexity, inefficient communication routes and an inexperienced workforce with many nationalities. SafetyEngine is an App for smartphones that digitizes all work environment related processes and documents to accommodate some of these challenges. A main element in the App is an efficient, engaging and 3D-based site safety introduction based on Gamification and BIM models. Furthermore, the App contains a digital information board, registration- and observation modules, and communication features.
Safety Observer 3.0
Read full descriptionHide full description
Safety Observer is a tool for measuring and improving workplace safety behaviour and safety conditions. It can be used in a wide variety of sectors and settings. It shows the workplaces' current level of safety expressed as the percentage of correct safety observations, which can be supported by notes, photos and smileys. Immediate results are provided on-screen and sent as a PDF report to your e-mail address. Results can directly be compared with results from previous measurements from the same or other workplaces. In the web-based 'administrator' module for the app you can customize your company's own observation lists and administer results (PDF reports and Excel statistics). The lists can be accessed by your company's 'users' for performing safety observations at various work sites.
