GRFv7 Note: In NewGRF v7 and lower the newly added base costs of OpenTTD (49-65) only apply if a base cost modifier is set for them. E.g. if NewGRF only set a base cost modifier for terraforming, but none for building foundations, the modifier for terraforming will also apply to building foundations, as that was the base cost used before the new one was added.

Note that some values may be adjusted by certain constant factors before being used by the game, but that is a property of the place where it's used, not the base cost as such.

Also, all constructions costs and all running costs are subject to modification by the game difficulty settings.
