How to calculate the floor area ratio of the general plant? What is the floor area ratio requirement

The plot ratio can be calculated by dividing the total area on the ground by the area of the planned land. Generally, the floor area ratio of the plant is about the same, and only when this standard is reached can it be the standard provision.

Plot ratio = total above-ground floor area Planned land area. The floor area ratio of a new plant is not clearly specified.

When calculating the floor area ratio, divide the sum of the floor area in the plant and the area of the structure by the total floor area of the plant; There are no clear rules for this.

Legal Analysis: Plot Ratio: The ratio of the total construction area within the project land area to the total land area of the project. Calculation formula: floor area ratio = total floor area total land area If the floor height of the building exceeds 8 meters, the floor area of the floor area is doubled when calculating the floor area ratio.

Industrial land plot ratio:

Except for projects with special rules or special requirements for occupational production such as safety and fire protection, the plot ratio of Class I industrial land shall not be lower, Class II and Class III industrial land plot ratio shall not be lower, and the floor area ratio of industrial land with special requirements for production technology shall not be lower.

The ratio of the total construction area in the planned land use of the industrial project to the area on the total land use of the project.

Accounting formula: plot ratio = total construction area total land area; If the floor height of the building exceeds 8 meters, the construction area of the floor shall be doubled when calculating the floor area ratio.

Legal basis: "Construction Law of the People's Republic of China" Article 2 Engaged in construction activities within the territory of the People's Republic of China, the implementation of supervision and management of construction activities, shall comply with this Law.

The term "construction activities" as used in this Law refers to the construction of all kinds of housing buildings and their ancillary facilities and the installation of lines, pipelines and equipment supporting them.

Legal analysis: Except for reasons to meet the requirements of production equipment and technical processes, the floor area ratio of each standard factory building land shall not be less than, and the number of floors of each standard factory building shall be more than 4 floors (inclusive) with industrial elevators. For the renovation of old factories and the construction of standard factory buildings of textile printing and dyeing environmental protection comprehensive treatment centers, the building floor area ratio can be relaxed to no less than.

Legal basis: Regulations of the People's Republic of China on the Quality Management of Construction Projects

47th local people's construction administrative departments and other relevant departments at or above the county level shall strengthen the supervision and inspection of the implementation of laws, regulations and mandatory standards related to the quality of construction projects.

Article 48 When the people's construction administrative departments at or above the county level and other relevant departments perform their duties of supervision and inspection, they have the right to take the following measures:

A) the unit to be inspected for documents and information on the quality of the project;

2) Enter the construction site of the inspected unit for inspection;

3) When problems affecting the quality of the project are found, they shall be ordered to correct.

Article 52 In the event of a quality accident in a construction project, the relevant units shall report to the local construction administrative department and other relevant departments within 24 hours. For major quality accidents, the construction administrative departments and other relevant departments at the place where the accident occurred shall, in accordance with the type and grade of the accident, report to the local people's ** and the construction administrative departments at higher levels and other relevant departments.

The investigation procedures for particularly major quality accidents shall be handled in accordance with the relevant regulations.

The formula for calculating the plot ratio: plot ratio = total above-ground construction area and planned land area.

The ratio of the total above-ground construction area (but must be the construction area above plus or minus 0 elevation) to the total land area of the project within the project land area. The floor area ratio is an important indicator to measure the intensity of construction land use. The value of the plot ratio is a dimensionless ratio, usually a multiple of the total floor area of the buildings on the plot to the plot area of 1.

1. There is no explicit provision on the floor area ratio of the new factory, and the floor area ratio = (factory building area + structure area) The floor area of the factory. For example, the total planned land area is 100,000 square meters, the total construction area is 150,000 square meters, and the plot ratio is 150,000 square meters.

2. The building floor area ratio refers to the ratio of the total construction area within the planned construction land of the project to the planned construction land area. Outbuildings are also counted, with the exception of annexes that do not count the area.

3. The underground floor area ratio can be calculated according to the planning and management needs of the underground construction area. In fact, it has always been stipulated by the local government itself, and it has been a good exploration of whether the basement is considered a floor area ratio and whether an underground commercial building (commercial building) is a floor area ratio.

Fourth, on an area of 100 square meters of land to build filial piety trace house, each floor construction area of 100 square meters, build 2 floors, a total construction area of 200 square meters, the floor area ratio is; If 3 floors are built, the floor area of each floor is 50 square meters, and the total construction area is 150 square meters, the floor area ratio is, and so on.
