Abstract
The present part is the last one of the paper, and the following sections are dealt with : In the section 1, the concrete techniques of calculating the main additional costs are described. In the first place, the methods of making the construction schedule during the winter and of picking up the input data are prescribed. Then the concrete processes of calculating the main additional costs of each winter measure are shown in the form of a flow chart. In the section 2, the methods of calculating the total additional costs and of assembling the estimated results are described. The total additional costs are to be drawn from the main additional costs multiplied by 1.1, a figure based on analyses of investigations of the actual winter buildings. The methods of assembling the estimated results are presented in the form in which a variety of analyses of the additional costs can be easily made. In the section 3, the applicability of the estimation system to the actual is inspected. The additional costs of the model buildings are estimated using the system, and are compared with the data obtained from investigations of the actual winter buildings. The results of the comparison prove the practicability of the system. In the section 4, the summary of this part is stated. In the section 5, some economic problems of winter building to be studied in the future are proposed.
