1. This table is formulated in accordance with Article 24 of the Rules for Estimating Land Price Survey, and should be handled according to the instructions when calculating the unit price of building improvements (hereinafter referred to as buildings).2. When using this table, the unit price may be determined within the range of unit prices listed in this table based on the level of property prices, the materials and equipment used in the construction. If the materials and equipment used in the building are significantly higher or lower than those stipulated in this table, the appraisers may state the reasons in the sale and purchase transaction form and make appropriate adjustments.3. The building usage listed in this table includes office, residential, shop, general market, and farmhouse. If the building is used as a hotel, restaurant, amusement park, large shopping mall, television station, hospital, department store, supermarket, or other public building, the unit price may be adjusted upward according to the unit prices in this table. If the building is used as a factory (plant) or warehouse, the unit price may be adjusted downward according to the unit prices in this table. For mixed-use buildings, adjustments should be made based on the percentage of usage.4. When the main structure of a building on the same building site has two or more types of construction, the unit price should be calculated weighted according to the construction proportion and the unit prices in this table. The main structure of the building refers to the structure of the building above ground level.5. When a building on the same building site spans multiple floor levels, the unit price should be calculated weighted according to the proportion of each part and the unit prices in this table. The number of floors refers to the highest floor of the building on the same building site.6. For buildings with a steel frame or steel-reinforced concrete construction of 41 floors or more, or reinforced concrete construction of 26 floors or more, the unit price may be adjusted upward according to the unit prices in this table.7. If the underground floor of a building meets the following conditions, the construction cost may be adjusted upward according to the unit prices in this table: for the portion beyond the first underground floor, an additional 30%; for the portion beyond the second underground floor, an additional 40%; for the portion beyond the third underground floor, an additional 50%; for the portion beyond the fourth underground floor (inclusive) and above, an additional 60%. However, if there are no excavation facts for the underground floor (such as caused by differences in terrain elevation), the number of floors should be deducted. (1) For buildings with 1 to 6 above-ground floors, if there are more than one underground floor, the excess portion. (2) For buildings with 7 to 15 above-ground floors, if there are more than 2 underground floors, the excess portion. (3) For buildings with 16 or more above-ground floors, if there are more than 3 underground floors, the excess portion. The number of above-ground floors refers to the highest floor of the building on the same building site.8. If the number of above-ground floors of a building exceeds the standard upper limit or is lower than the standard lower limit listed in this table, the unit price of each floor may be adjusted upward or downward according to the unit prices in this table, and for each 0.1m beyond or below, a 1% price adjustment. For parts of the building with increased height, adjustments should be made based on the proportion of the increased area and the weighted unit price.9. When a building on the same building site has two or more of the conditions specified in notes 3, 7, or 8, the unit price should be calculated by multiplying these conditions.10. The unit prices in this table include the construction costs, taxes, profits, and management fees of the contractors; for buildings with 6 floors or more, elevator equipment is included. However, for buildings with 5 floors or fewer and equipped with elevators, the unit price should be adjusted upward according to the unit prices in this table, and for buildings with 6 floors or more without elevator equipment, the unit price should be adjusted downward according to the unit prices in this table.11. This table is based on January 111 of the Republic of China as the base period. When the price date is different, adjustments may be made based on the total index of the Taipei City Construction Engineering Price Index published by the Taipei City Government's Department of Budget, Accounting and Statistics.
