Plant expansion

Q: The Player's Manual states that when our company built its plant in our home area, there was space for two new lines on each side of the new plant.  Does that mean that if a company builds a new plant with a capacity of 6 lines that the maximum number of lines they can have after plant additions is 6 + 2 + 2 = 10 lines?  We built an 8 line plant in Sereno from the get-go and will get to 12 lines soon, but my team is interested in the fate of the other teams that made 6 lines or less from the beginning in Sereno.

A:  The maximum plant size in any area is 12 lines, no matter what the original size of the plant was.  Expansion can be undertaken by building additions with two lines capacity--one addition being the maximum  to start in any quarter.

Each addition will provide space for two production lines.  Your existing plant shell has room for eight lines. Adding two more will give you space to install a total of ten lines. Two quarters are required to complete construction of a new addition.

The installation of production lines in the addition may be started during the second quarter of addition construction so that the lines will be available for production as soon as the plant addition is completed. Construction may begin on only one two-line addition for any plant during any quarter. If desired, however, construction may be started on another addition in a subsequent quarter while the first is still under construction, provided that such construction will not cause the maximum plant capacity of twelve lines to be exceeded.
