If you want to use the replimat mod with this modlist, you will need the dev version of DocWorld. Otherwise, the replimat parts will not show up in the architect menu.

Go to this github page: https://github.com/DrZhivago1/DocWorld/tree/dev
Make sure you're downloading the dev version.

Then, add it as a local mod like you would any of the fixlist mods.

Let me know if anyone has any questions. :)
