Detailed walkthrough
The quest starts when you enter the institue after finishing the Mass Fusion Quest. First, you must speak to father, then, you are told to go to the house of T.S. Wallace, a wastelander who could help the project. The minutemen arrive there, and from here you have three choices- kill the minutemen, Side with them, or convince them to stand down. If they either stand down or get killed, you must then go into the house of T.S. Wallace, where another speech check is required in order to get him to go to the institute.
