This was my target build layout to do speedruns with the 0.14 release. My best time using it single player was 05:42:35 with hostile aliens. Note that these screenshots were taken in a much more advanced save game where it was designed with robots. The actual speedruns of course didn't turn out exactly like this and I never used concrete in them (and I always built the science labs out to the right, they're only turned sideways here to fit). The second screenshot shows the slight change I would make to switch from researching science pack 3 to low density structure for the rocket.

Nice try ... but you build are to expensiv.
Speedrun means to build as fast and cheap as possible.
Red belt ... dont use it ... to expensiv.
Blue inserter only when really necessary.
Use Wooden pole instead of Steel ones.
Have a plan and know the map!

Here the result after 3 Hour and a launched rocket. https://www.youtube.com/watch?v=R3pVLAVwphE

And there is still much room to improve

Nice speedrun build. I know there are many improvements and techniques beyond what I've done. I was merely sharing my creation that I made clean and concise as a reference design.
