In this guide we will discuss how to put together production lines that can produce 14.4k foundations per minute sustainably to help you pave over planets at record pace. We will also be applying proliferator to the foundations which means that you will gather more soil pile and use less soil pile to cover up holes in the ground! We will start by covering the high level recipes we will need and then discuss each of the production lines in detail.
If you are just here for the proliferated foundation blueprints, here they are:
At a high level, foundations are made up of stone bricks, which are made from stone, and steel, which is made of iron ingots which is what you get from smelting iron ore. For 14.4k foundations per minute we need the same amount of steel per minute and 3 times the amount in stone bricks (43.2k). For 14.4k steel per minute we need 3 times the amount of iron ingots per minute (again, 43.2k). 14.4k foundations per minute is the equivalent of 2 full Mk.III conveyor belts stacked to 4 items high. We will look t the detailed requirements for each of these production lines next.
Starting with the iron ingots and stone which are very similar (the only difference is the recipe). You will need the technology of the transportation stations piling items to 4 high to be able to follow this guide. If you don’t have that tech, you will only get to a fraction of the output rates. The key challenge to solve is (1) the number of smelting machines needed to fill a Mk.III conveyor belt and (2) how to merge 4 of those single item stacked belts to one belt with items piled 4 high. Looking at the piled items first, each of the 4 full conveyor belts need to go into an automatic piler. Each 2 of those lines then need to be combined together using a splitter. I usually do this vertically to limit the use of horizontal space to be able to pack in more production lines on a planet. Using tab the splitter can be changed to split or merge vertically. To produce a full single piled conveyor you will need 8 of the plane smelters with proliferated inputs using the 100% production boost option. I usually use 4 production lines per transportation station.
The steel is quite similar except that it takes 3 iron ingots to make 1 steel. This means that I only use 2 production lines and draw out 3 iron ingot lines per production line from the transportation station and merge the extra iron ingot lines 1/3 and 2/3 along the production line. For the steel it takes 23 plane smelters again using proliferated inputs with a 100% production boost to fill up Mk.III conveyor belt piled 1 high.
The foundation is very similar to the steel except that it takes both steel and stone bricks on the input. Like the iron ingots for the steel, it takes 3 stone bricks per foundation is I again only used 2 production lines and drew out 3 lines of stone bricks refreshing the input lines 1/3 and 2/3 along the production line. It takes 10 Mk.III assemblers to produce 30 foundations per second which is enough to fill up a Mk.III conveyor belt. Be sure to apply proliferate to the foundation output which gives you 25% soil pile pick up and reduces the soil pile cost of filling in holes/ water by 25%.
So there you have it! You now have all the production lines to produce 14.4k foundations per minute. Just put down the production lines multiple times if you want even more. I usually use multiple transportation stations with local demand and remote supply to build up foundation storage so that, when I need foundations, I can just keep picking them up for quite a while before the storage runs out. And even if the storage runs out, the transportation stations will be full again in a matter of minutes.
