Since the begining of space engineers we have 3 types of building: station, small ship and large ship. What I suggest is a 4th type of building: infrastructure.
It would be a build with only one grid (the base grid and no subgrids), and no terminal blocks nor energy.
It's only purpose would be to build infrastructure.
Because althought you can do it using stations the grid of the stations are always loaded in the game, and if you dont power them they are likely gonna be removed by the garbage collector.
The infrastructure builds will be saved like the terrain in the planets and only loaded if the terrain in that place is loaded, which would give the player hability of building infrastructure (roads, rails, scafolding, bridges...) without having to melt their pc in the process.
