In General
The Engineering Bay houses the engineering team, headed by Dr. Shen.
Build/Buy Items
Here you can build or purchase items that you have the resources for.
Item Production Speed
Each engineer increases the speed of item production through a complex formula:
Build Time = Base Time * 0.5 * [1 + (Optimal Engineers / Actual Engineers) ^ (0.06 * Optimal Engineers)] / (1 + 0.2 * Number of Workshops)
As long as the the number of available engineers is much lower than the recommended value, recruiting an additional engineer will significantly reduce the completion time. As the number of engineers approaches or exceeds the recommended number, then adding additional engineers has diminishing returns, i.e. each new engineer reduces build time by a smaller and smaller amount.
Item Fabrication Capacity
The Engineering Bay grants an item fabrication capacity of 2. This means you can produce a maximum of 2 different item orders simultaneously. All other item orders will be queued to start once they finish. The item fabrication capacity is increased by 1 for every workshop.
Rushing
Rushing the production of an item reduces the base build time by 80%. The cost is 40% more resources and 5 meld.
Due to number of engineers affecting actual build times, when rush building, the final build time will likely not decrease by a full 80% (Click here for more info: Scientists and Engineers)
Build Facilities
By selecting "Build Facilities," a listing of the new facilities available for construction will be provided, along with the associated resource costs and time required for construction. There is no limit on the amount of excavation or construction that can be done at once.
Rushing
Rushing the production of a facility reduces the base build time by 80%. The cost is 40% more resources and 10 meld. Excavations cannot be rushed, and take 8 days to complete.
