The Building Guild organizes and coordinates all construction projects in the city. Experienced craftsmen gather here to increase efficiency in construction work.
How the Building Guild Works
The Building Guild has no job of its own. Instead, its productivity factor determines how much construction progress each work hour contributes to construction orders. The higher the Building Guild's level, the faster all other construction projects in your city advance.
Why Upgrading Pays Off
Since practically every construction project and every repair benefits from the Building Guild, it is one of the buildings with the greatest leverage on your city's overall progress.
Construction Costs and Productivity per Level
The difficulty factor matches the value your city currently uses (default 100%). Enter your own value here to see your city's actual construction costs. The calculation happens only on this page in your browser and does not change anything about your city.
