This tab only appears when you have started constructing buildings. It has multiple subpanels: Constructed, Under Construction, and Managers. This view allows you to manage things related to your establishments.
Constructed
Constructed buildings have their name, type, and location. You can click on a building's location to move to it, or click on its name to manage it. Building management will open in a new window. E.g. marketplace settings.
Under Construction
Buildings that are under construction are listed with their name, location, time to completion, percent completion, rate of material consumption for construction and paying builders, amount of additional materials required for completion (construction costs and builder salaries), and number of builders.
Additional builders can be hired here, or fired, to decrease the build time or cost to build, respectively.
Managers
This subpanel shows the current NPCs you have in your employ running the buildings you have constructed, and the jobs necessary to support your city. It shows the currently hired managers' names, effectiveness, and pay. Managers can be reassigned or fired from this tab. Periodically new managers will also appear on this page with the option to hire them.
