Building Dimension Guide

The "Nominal" dimensions listed are for the dirt road cost and do not include the road width. If it's adjacent to a road, you need to add 25 for each road or 49 for each avenue. I've already done this additional calculation for you and added it as additional columns.

Example: Omega HQ is listed as 390 x 390. Suppose you want to surround it by roads. Then you would add 25 for each road so 390 + 25 + 25 = 440. Construct a 440 Simolean long dirt road and you will have the proper length. Similarly, if you want to surround it with avenues you would add 49 for each side so 390 + 49 + 49 = 488.
