Social construction

Social construction refers to all non-ship construction performed at colonies.

Generation in
, like, is a linear function of , computed by adding the total flat bonus to and then multiplying by the total multiplier bonus. The total multiplier to is independent of the multiplier to : a +20% bonus to  and a +20% bonus to  will result in a 1.44x multiplier to net.

Therefore, is usually the most important determinant of.

is allocated by assigning population to construction, and then setting the social/ship construction slider.

Improvements
The primary use of social construction is improvements: constructions that take up one hex each on the planet surface and provide a bonus to the colony.

Project
Social construction may be spent on projects to increase the output of other resources. Each 10 points of social construction gives +10% to the production of the resource specified by the project for that turn:

The more production a planet has, the more efficient these projects are; however, they are generally less effective than appropriately specialized planets unless extreme amounts (~hundreds) of production are reached.

Synthetic assembly
Synthetic races increase their population via projects.

Shipyards
Colonies may produce Shipyards in order consume to manufacture Ships.
