What is acquired in this series of study (Study on B.E. Quantity I, II) could be highly appliable especially to cost study. Study 3 is one of the examples of its application to the cost study of apartment houses. Generally, cost study includes two phases of study; one is on unit cost of Building Element and the other on quantity of B.E. The former means the studies on the selection of construction method or material, and the latter means the study on the distribution of the quantity to each part of building which is caused from the characteristics of the design. Naturally this study belongs to the latter type of analysis, and it aims to determine the distribution of cost not by the usual method of using the practical data but by the theoretical method which is based on the theory of B.E. Quantity. The summary of this paper is as follows; 1) Introduction. 2) Relation between the cost and the amount of stories; In accordance with the increase of the height of building (under the condition of total floor area being constant) such quantities as of perimeter wall, partition wall, roof, and other elements would be changed. Consequently, the change of total cost would be expected, and we have studied the fluctuation of the cost and tried to acquire the point of minimam cost. 3) Relation between the total floor area and the cost per square meter of floor area. The usual method of rough cost estimate has been, so to speak, floor area method, but it has inevitably the possibility of much error. In this chapter, making use of the theory of B.E. Quantity, we show the range of the accuracy expectable for this method. 4) Relation between the cost and the proportion of the square plan of an apartment : The proportion means the ratio of the width per the length of a dwelling in an apartment house. Even if the total floor area is constant, the ratio can be variable, so that total cost cannot be considered constant. In this relation, as well as the case of the chapter I, minimam cost point can be found. After all you can see that it is determined only by the ratio of unit cost of several building elements.
