Now, that would be 29 "constructions" by my count. We get 4 per turn, and we only get 5 of those. Well, 6 if we feel slightly suicidal. Then again, building a fuel-tank really shouldn't be that time consuming as it is now... *nudge-nudge*, *wink-wink*
Ahem. Looks fine in the rest of things thou. One thought - upgrading is always more difficult than building anew. (Small-scaled changes not-withstanding). How about we decide our "needed" cargo, see our RU-buffer, and then give half or quarter of it to research better expanded superstructure? We obviously would construct small stuff that doesn't get us above that 60% Treshold in this round, and if the dice favour us, we won't need a third expansion.
As for the cargo - bare necessities version;
1 Oxygen Extractor. Cost 5 RU. Size 2, Mass 4
~3 Air tanks & vac suits. 1 RU, Size 1, Mass 1 (4 units - 1 and a spare for each awake crewie)
~4 Air. Cost 1, mass 1 (hullbreach-backup/safety)
1 Seed Bank. 2 RU, 4 mass, 3 size
1 Hydroponics kit. Cost 7 RU, Size 6, Mass 5 (mostly for the included blueprint / expansion)
1 Ore Processor. Cost 6 RU, Size 4, Mass 5
1 Manufacturing equipment. Cost 9 RU, Size 3, Mass 4
1 Digging & drilling vehicles. Cost 2 RU, Size 4, Mass 4
38 RU, 29 Size, 33 Mass
Leftover RU; 56
Leftover Cargo-Space; 11
On another note - a "research" proposal;
Elite Crew - 10? RU
We scan the available personal for the very best of the able - and stable - minded, the most healthy, those with adamant discipline - and something to loose and live for! (family...)
We will try to get enough of them as to allow for a healthy rotation and rendering of service, but will not cut any corners on their quality... (if we should be short-handed, future preferential treatment for their families will be promised - and undoubtedly kept!)
We then give them hands-on experience with the tools and programs they will use, and those that we fear that they might need to use. ([this training could be further enhanced, should time and lack of other research allow so])
We will mold them into the very best that humanity has to offer!
