Charis Analytics vs PreFlight

Charis Analytics mobile application is a digital solution that allows you to track the progress of your infrastructure projects in near-real time, keeping the contractors accountable and ensuring a timely completion of projects. 1. Virtual Representation with Measurement and Comparison Tools: Virtual Site Model: Charis Analytics creates a digital replica of your physical site. This could be through 2D plans, 3D models, or even immersive technologies like 360° in-door scan. Measurement Tools: The app allows you to take measurements directly on the virtual model. Imagine calculating distances, areas, or even volumes of materials right from your phone or tablet. Over-Time Site Structure Comparison: This is a powerful feature that lets you compare the virtual model with itself at different stages of construction. You can easily visualize the progress made, identify any deviations from the plan, and ensure everything is on track. 2. Downloading and Sharing Project Files: Enhanced Collaboration: Charis Analytics allows you to download essential project files directly to your device. This makes them readily accessible for yourself, contractors, and other stakeholders on the go. Streamlined Communication: The app facilitates easy sharing of project files, improving communication and keeping everyone informed.
