This Blueprint installs to slot 14 by default.

Before importing, remove all the original items that the default game allows (such as plants etc but not items that a scrapper would, for example the communications tower)

You will need to have installed Transfer Settlements (I used v1.93) and its pre-requisites: F4SE and HUDFramework.

The settlement has 9 beds, 10 water, 12 food, 100 power and 92 (8 from spotlights) defence. This build also has chemistry, power armour, armour, weapon and cooking stations.

There are 8 jobs available. 
Tier 2 clinic. Tier 2 Bar. Tier 2 General Store. Tier 3 Weapon seller. Booze Still. 2 farmers. Scavenger station (it is partly glitched in to the shipping crate near the nuclear reactor).

There are 1163 items to import. If you are having performance issues removing the spotlights might help.

There is a disconnected settler beacon near the bus. There are power conduits nearby if you wish to connect it.

There is a table lamp in the bus, it will not be lit once imported. To activate the lamp go into workshop mode, select then deselect it and it should now be working.

The json file is just a list of objects and their locations and as such should not have issues importing.  If there are problems,  try selecting general settings, scroll down and choose PRESET: stable. This might help in some circumstances though the import will take longer, otherwise there is help in this excellent article or on the  transfer settlement mod page. I think there is also a discord server as well.

I did use Place Everywhere to make this build (though you don't need this) and I spawned some scrapable items using the console.
