This location is part of the Miscellaneous quest given by Mayor Kessler in Bunker Hill. Some of the closed doors in the first floor are chained from the other side so you need to access them from the second floor. Chemistry Room in the second floor has a mini-nuke on top of a table.
The boss of the raider group, Zeller is found on the third floor. The captured caravan workers are inside individual cells in the third floor. Each cell has a Novice lock.
The green steamer trunk is located to the SE of the third floor. In the computer room to the SE of 3F has an Advanced safe and an issue of Astoundingly Awesome Tales, on top of a desk. The cooking station is located in the restroom to the NE.
The room to the NW of the first floor can only be accessed by falling through the hole on the floor of the SW second floor room, directly above it. There are several containers inside including a locked explosive crate and Book Return Terminal. The terminal doesn’t have anything noteworthy as prize so just return the overdue books you may have and collect the tokens for now.
