Calculated based on the area indicated in the design drawings. b. Calculated based on the actual area as shown in the design drawings. c. The area occupied by trenches and similar elements should be deducted. d. The open areas of the heating ducts should also be included in the area calculation. Answer: d Analysis: For the overall floor covering in floor construction, such as cement mortar floors or cast-in-place terrazzo floors, the area is calculated based on the dimensions indicated in the design drawings. The area occupied by structures that protrude above the ground, equipment foundations, gutters, etc., should be deducted. Areas occupied by columns, pilasters, partition walls, chimney attachments, and holes with an area of 0.3 m2 or less shall not be deducted; however, the open areas of doorways, hollow spaces, and heating ducts are also not included in the calculation. The unit of measurement is m2.
