Final answer:
The recommended permission level on Procore's Photos tool for architects and engineers who need to upload photos but should not access configuration settings is 'Upload Only'. This level allows for efficient project collaboration without compromising security.
Step-by-step explanation:
The recommendation for which permission level to give architects and engineers on the Procore Photos tool, if you want them to be able to upload photos but not have access to configuration settings, is the Upload Only permission level.
This permission allows users to contribute photos to the project, facilitating collaboration and documentation, without granting them the ability to alter the configuration settings or delete content. This strikes a balance between operational security and the need for efficient collaboration. Procore's permission levels are designed to provide project managers with the flexibility to assign appropriate access rights to different users based on their roles and responsibilities in a project, having nuanced options available.
