Construction

Construction
Skill type	City
Description	Construction speed: +2% per level
Requirements
Building(s)	University: level 1–30 Palace: level 1–30
Formula [Help]
$resources \begin{bmatrix} food \\ wood \\ stone \\ copper \end{bmatrix} = \begin{bmatrix} 40*level^2 \\ 40*level^2 \\ 120*level^2 \\ 40*level^2 \end{bmatrix}$ $time \mbox{ [seconds]} = 400*level*(level+1)$

Construction is a City skill which can be learned at the university. This skill increases construction speed of buildings. At every level, construction speed is increased by 2%. The maximum boost at level 20 would be 40%. The boost can go up to 60% at level 30, although a level 30 university can only be built in a famous city.

Construction time

The time it takes to build any particular building is given by this formula:

$time = t / (1 + c * 0.02 + s * 0.005)$

where t is the original (base) time given, c is the construction level, and s is the amount of skill points of the governor.

For instance, for a level 15 village takes 3:45:12 base time (225.2 minutes), a construction level of 20, and a governor skill level of 214, we have (225.2 minutes) / (1 + 20 * 0.02 + 214 * 0.005) = 91.17 minutes, or 1:31:11.
