**第一項**  法附則第八条第一項に規定する政令で定めるところにより計算した金額は、同項に規定する長期工事に係る対価の額に、適用日の前日の現況により当該長期工事につき見積もられる工事原価の額のうちに当該長期工事の着手の日から適用日の前日までの間に支出した原材料費、労務費その他の経費の額の合計額の占める割合を乗じて計算した金額とする。

The amount calculated as specified by Cabinet Order prescribed in Article 8, paragraph (1) of the Supplementary Provisions of the Act is the amount calculated by multiplying the amount of consideration for the long-term construction prescribed in that paragraph by the proportion accounted for by the total amount of raw material costs, labor costs and other expenses paid during the period from the day of commencement of that long-term construction to the day preceding the application date, in the amount of construction cost estimated for that long-term construction on the basis of the situation as of the day preceding the application date.
