All construction tasks require at least three workers to begin. A new structure or ship will be created, and the builder will be placed inside.
Construction proceeds until completed unless maximum days has been specified.
Any of these commands can also be followed by a maximum number of days to work. This will be misinterpreted by the game with unpredictable results. The first tower a player builds requires no workers, no stone, and only takes a day to build. For more details, see Buildings and Ships .
