The relationship between the cost of the building and the number of floors

Actually, it's not like that. First of all, the cost of civil engineering is concrete + steel bar + other, in which the cost of concrete is generally unchanged, and the cost of other costs is not much different, and the cost of steel bar is higher (within the reinforced concrete structure) The less steel is used, the lower the cost.

Secondly, the higher the land apportionment** floor, the smaller the apportionment ratio, and the lower the apportionment amount of each household. The total cost is also reduced.

Third, the public area apportionment, the higher the floor, the more households, the public area is certain, and the proportion of apportionment is smaller, so that the cost per square meter is lower.

Fourth, the cost of the elevator is certain, the higher the floor, the more households will be apportioned, and the cost per square meter will be reduced.

Therefore, the cost per square meter is relatively the more floors, the lower the cost. It's relative, though. Generally speaking, the cost per square meter is about 1,000 yuan (excluding land apportionment fees, only civil construction costs).

Take a spot, expect a master. Personally, I think that from the construction point of view, the increase in the number of floors in the cost increase is mainly reflected in the increase in the cost of construction measures, such as the increase in the cost of ultra-high costs, the increase in the cost of external scaffolding, etc., but the proportion of increase is not much, the key is the increase in the cost of design. For example, the amount of steel bar, concrete number, concrete consumption, fire protection and other requirements, this has a greater impact on the cost.

Hehe, I'll answer:

Regardless of commercial factors, the more floors are definitely the higher the cost, and generally speaking, about 18 meters (about 6-7 floors) of the foundation utilization is basically sufficient, the lower the utilization rate. If the profit factor is considered, it must be that the higher the number of layers, the better the profit, because the return per unit of land area is high, and the basic contribution rate is high.

Floor height refers to the difference in height between the ground of this floor and the ground of the previous floor.

The total cost of each project to build a building is:

Pile foundation engineering: generally about earthwork, foundation, masonry, concrete, steel bar accounts for about 50% of the project cost.

Waterproof engineering: roof waterproofing and insulation, floor floor, wall columns, doors and windows, paint and coating account for about 10% of the project cost.

Hydropower and heating projects: Hydropower and heating account for about 15% of the project cost.

Formwork, scaffolding measures, etc. account for about 8% of the project cost.

Profits, taxes, management fees, etc. account for about 20% of the project cost.

The direct meaning of the project cost is the construction of the project. The three elements of project valuation: quantity, price, and cost.

The project cost refers to the total cost of carrying out the construction of a project, and its core content is investment estimate, design estimate, revised budget estimate, construction drawing budget, project settlement, final account and so on. The main task of project cost: according to the drawings, quotas and list specifications, calculate the direct costs (labor, materials and equipment, construction machinery and tools used), enterprise management fees, measure fees, fees, profits and taxes and so on.

The height of the column is floor to roof plate.
