Abstract
First, the telephone office building design process was standardized and located using these methods, -"In-place-cost estimating method" and multiple regression analysis method-to correspond to the standardized phase, and a attempt was made to lay down a concrete cost planning procedure. Besides, "first class cost for a guide" was studied in this procedure. Second, the "In-place cost estimating method was illustrated and dealt with in part-1 by new data. Also, the "estimating of whole building cost" was reviewed again theoretically from an actual use stand-point and its practical use was attempted.
