concurring specially.
I concur fully in Divisions 2 and 3 of the majority opinion. Because we are bound by the holding in German v. Dept. of Transp., 162 Ga. App. 785 (293 SE2d 50) (1982), I must agree that the erroneous charge on consequential benefits does not require reversal in this case. See also Dean v. Oglethorpe Power Corp., 179 Ga. App. 528, 529 (2) (346 SE2d 906) (1986) and Gardner v. Dept. of Transp., 165 Ga. App. 300 (1) (299 SE2d 741) (1983).
