The Tobacco rare resource increases the current building progress by 10%.Thus, when this line is fully researched, a building only requires 70% of the original building time. The construction line of upgrades at the Lumber Mill decreases the building time by 10% per upgrade.It would take 83 citizens to complete a building in 1/5 the time. The build time, based on the number of citizens constructing the building, is as follows:Īs a rule of thumb, 4 citizens will complete a building in half the time, 11 citizens will complete a building in 1/3 the time, and 30 citizens will complete a building in 1/4 the time. If three citizens are assigned to the building, then the building will take 1000/(1+1/2+1/3) = 545 frames to construct. If two citizens are assigned to the building, then the building will take 1000/(1+1/2) = 667 frames to construct.

This means that a single citizen will build it in 1000 frames. Thus, although each additional citizen will decrease the building time, it is generally inefficient to assign many citizens to construct the same building.įor example, suppose a building takes 1000 frames to build. The nth citizen simultaneously constructing a building will only contribute 1/ n of the standard build rate. Thus, there is a tradeoff between how quickly a building is built versus the number of citizens taken from other tasks to help build it. However, each additional citizen is less effective. In Rise of Nations, multiple citizens can construct a building simultaneously. For the build rate of units, see Build Rate (Units).Ĭitizens are used to construct buildings, including wonders. This article is about the build rate of buildings.
