Brim Quarry is at the top of a hill in the Ash Heap. There is a control tower at the bottom of this hill with a crane and shipping containers outside. Inside the control tower is a cooking station, a sleeping bag, and a desk with a typewriter and a note. There is a foreman's key which will open several locks around the location hanging on a pegboard on the wall.
The main building and quarry are at the top of the hill. Several vehicles including cranes and off-road vehicles are parked outside the main building. An armor workbench, tinker's workbench, and a Fire Breather corpse is lying against a fusion generator. Inside the building is a locked desk, a filing cabinet, and a wall safe, all of which can be unlocked with the foreman's key. The building also contains an explosives crate and several lockers. Several Fire Breather corpses can be found throughout the location.
