About Underwater Construction
From ficsit.appBuild underwater!
Construct buildings while swimming and diving!
Along with allowing you to build underwater, this mod changes the character buoyancy so you sink slowly instead of floating, making it easier to stay underwater and build. This can be changed in the Mod Savegame Settings, however.
This mod pairs especially well with Swift Swimming.

SirDigby's completely optional tip jar
Indifferent Broccoli provides the server I use to test Dedicated Server mod support, and I highly recommend them. If you're looking to host your own Satisfactory server , try indifferent broccoli's 2-day free trial.
