Intel Center L3 confirmed

Major evidences can't be handed in until Intelligence Center L3 is built. L3 is one of the more demanding hideout stations — it stacks on top of Library, Workbench L3, and a long material list including Military COFDM Wireless Signal Transmitters and Advanced eyewear. If you don't already have it, this single requirement can stall the whole Savior route by hours or days.

Use the build window to collect majors that don't need L3 to obtain (everything except the hand-in itself). Three of the eight should already be in your stash from earlier chapters; the rest can be staged before L3 finishes. Once L3 is up, the laptop dialogue option to deliver evidence appears automatically.
