General civil building construction and installation engineering
make it clear
1. The quota in this chapter is based on the "Construction and Installation Project Duration Quota" (draft) formulated by the former Ministry of Construction 198 1 year, and is installed by the state.
Inspection and evaluation standards, construction and acceptance specifications and other relevant provisions, combined with the situation of trial construction period in various places, were revised on the basis of extensive investigation and study, in line with the principle of average advanced and economic rationality.
Second, due to China's vast territory, great differences in natural conditions, and different construction equipment and physical quantities of similar projects, the whole country is divided into zones I, II and III, and time limit quotas are formulated respectively.
Class I areas: Shanghai, Jiangsu, Zhejiang, Anhui, Fujian, Jiangxi, Hubei, Hunan, Guangdong, Guangxi, Sichuan, Guizhou and Yunnan;
Class II areas: Beijing, Tianjin, Hebei, Shanxi, Shandong, Henan, Shaanxi, Gansu and Ningxia;
Three types of regions: Inner Mongolia, Liaoning, Jilin, Heilongjiang, Tibet, Qinghai and Xinjiang.
In the same province and autonomous region, due to different natural conditions, the construction period can also be classified according to the principle of regional classification of construction period. Regional classification shall be carried out by the competent construction departments of provinces and autonomous regions, and after being approved by the Ministry of Construction, the time limit for two regional classifications shall be implemented respectively.
Three, this chapter quota in calendar days (months) as the unit.
The time limit for a unit project refers to the period from
All calendar days from commencement to completion of all the contents specified in the engineering design or quota subtitle and reaching the national acceptance standard.
Four, the implementation of winter construction area, because the construction technology is not allowed or the economy is unreasonable, can't continue the construction, with the consent of the construction (contracting) unit, according to the actual number of days to postpone the construction period, but the number of days to postpone shall not exceed 40% of the heating period in Class II area and 50% of Class III area.
Five, this quota is based on the comprehensive consideration of the situation in various regions, because of the different levels of industrial development and construction conditions in various regions, giving nine provinces, autonomous regions and urban and rural construction departments such as Guangxi, Ningxia, Inner Mongolia, Tibet, Xinjiang, Guizhou, Yunnan, Qinghai and Heilongjiang the right to adjust the quota level within 65438 05%; Give the competent departments of urban and rural construction of other provinces and municipalities directly under the Central Government the authority to adjust the quota level within the range of 10%. The competent departments of urban and rural construction of all provinces, autonomous regions and municipalities directly under the Central Government may formulate detailed implementation rules according to the above provisions and report them to the Ministry of Construction for the record.
Six, the quota within "XXX" (or below), including "XXX" itself.
make it clear
1. The unit project time limit quota subtitle is divided by use, structure, area and number of floors.
2. Multi-purpose unit project duration, fixed duration for different purposes, calculated according to the weighted average area.
Example: 7,000 ㎡ mixed structure project with five floors in a first-class area, in which: 4,200 ㎡ shops are located below the third floor, and 2,800 ㎡ offices are located on the fourth and fifth floors. The inspection quota is11-18 (310 days), 4- 17 (240 days), and the construction period = (4200× 310+2800).
3. The unit time limit for a project of various structures shall adopt fixed time limit for a project of different structures, and be calculated according to the weighted average area.
Example: 25,000m2 revolving hall project in Class II Area 1 Building, in which: internally poured peripheral structure 10000m2 and cast-in-place frame structure 15000m2. Check the quotas 5-52 (550 days) and 5- 10 1 (704 days).
Time limit for a project = (10000× 550+15000× 740)/25000 = 664 (days).
4. The unit time limit for a project composed of different floors, when the area of the high-rise part accounts for 30% or more, the time limit for a project shall be calculated according to the high-rise quota; When it is less than 30%, the construction period shall be calculated according to the number of low floors.
If the construction period is calculated according to different floors, the provisions of Articles 2 and 3 will no longer be implemented.
Example: the third-class area 15000m2 assembled frame housing project, in which: 10 floor is 5000m2, and the eighth floor is 10000m2. Because the 5000m2 of the 10 floor accounts for 33% > 30% of the total construction area, the quota is 15000m2 of the 10 floor. Check1-180, and the construction period is 485 days.
5. The ground floor of a residential building or other building is a shop, and its construction period should be combined with the construction period of the residential building or other building, and shall not be used for a separate shop project.
6. Basement quota,
The project time limit for a project should be with the basement,

9. When the foundation construction encounters unforeseen obstacles or ancient tombs, cultural relics, quicksand, caves, hidden banks, silt, etc. If treatment is really necessary, the construction period can be extended according to the actual treatment time through negotiation between Party A and Party B. ..
10. The foundation excavation in the quota shall be subject to the three types of soil. For four types of soil, the unit construction period is multiplied by the coefficient 1.02, and the stonework is multiplied by the coefficient 1.05.
1 1. In the quota, the buried depth of foundation (from the outdoor terrace) is 2m in the first and second class areas, and within 2.5m in the third class areas. For every increase of 1m, the treatment period is 10 days (excluding lime-soil wells and concrete well columns).
The construction period above 12.8 has included the foundation construction period such as piling, but when the pile length exceeds12m, the construction period of the extra-long part will increase. The project below the 7th floor does not include the piling period, and if there is piling, the piling period will be increased.
13. For the technical floor whose height is less than 2.20m (excluding 2.20m), the number of floors and area are not calculated, and the construction period is calculated as half of the construction period difference between adjacent floors.
14. The number of floors in the theater refers to the number of floors in the audience hall; The number of floors in the boiler room refers to the number of floors in the boiler room.
15. The cast-in-place frame structure in the quota refers to full cast-in-place (beam, column and slab). In case of partial cast-in-place and partial prefabrication, the construction period shall be multiplied by 0.96 coefficient according to the construction period of cast-in-place frame.
16. The canteen duration in the quota is also used for the auditorium project. If there is a suspended ceiling, stage and projection room, the construction period shall be multiplied by the coefficient 1. 10.
17. The hotel construction period in the quota has included the kitchen and dining room with an area of less than 300 square meters. If the area exceeds 300 square meters, the project is calculated according to multiple purposes.
18. The duration of high-end stores is multiplied by the coefficient 1.55 according to the duration of one store.
High-grade shops refer to: tile or high-grade veneer on the outer wall, wallpaper (cloth) on the inner wall, pre-shed veneer or high-grade decorative plaster,
Or Marseille floor, aluminum alloy steel doors and windows, advanced light grids, air conditioning, automatic fire fighting system.
19. The duration of single dormitory is multiplied by the coefficient of 0.90 according to the duration of residence.

Section 2 Group Project
Section 2 Group Housing
make it clear
1. Group housing projects refer to two or more buildings.
The conditions of residential projects do not include supporting cultural, commercial and public facilities and various pipelines, greening,
.
2. Multi-storey houses and multi-storey group houses refer to houses and group houses below 8 floors; houses and group houses below 9 floors are called high-rise houses and high-rise group houses.
3. This quota is limited to 7 30000㎡ multi-storey houses and 3 or 5 60000㎡ high-rise houses. If it exceeds the above provisions, the construction period will be postponed according to the difference between the last adjacent floor, area and number of buildings.
4. In group residential projects, when the construction area of high-rise residential buildings accounts for 50% or more of the total area, the construction period is calculated according to the high-rise residential projects, and the number of buildings is the number of high-rise residential buildings plus the number of multi-storey residential buildings converted into high-rise residential buildings; When the high-rise area is less than 50%, the construction period is fixed for multi-storey and high-rise residential buildings respectively, calculated according to the weighted average area.
Example: A group of 7 external residential buildings with a total area of 32,000 ㎡ are poured in the second-class area, including 16 floors, 165㎡2 buildings with 6 floors and15,500 ㎡ 5 buildings. The construction period is:
(1) The area of high-rise residential buildings accounts for 50% of the total area p = (16500/8250) ×100% = 51.56 >, that is, a set of fixed construction period of high-rise residential buildings.
(2) Multi-storey houses are converted into the number of high-rise houses by area, namely15500/8250 =1.88 ≈ 2 (buildings).
(3) After conversion, it is 32,000m2 for 4 buildings 16 floor, with the approved quota of 32-32 and the construction period of 24.5 months.
5. In high-rise residential projects, when there are two or more different floors, the fixed construction period of residential buildings with different floors and weighted average area should be applied to calculate the construction period.
Example: There are five 56,000m2 slip-form group houses in Class III area, including 30,000m2 for three buildings on 10 floor and 26,000m2 for two buildings on 16 floor, with the approved quota of 32- 128, 32- 152 and the construction period of 24.5.
(30,000× 24.5+26,000× 29)/56,000 = 26.5 months
6. For group houses with different structures, the fixed construction period of different structures shall be adopted respectively, and the construction period shall be calculated according to the weighted average area.
Example: There are 5 buildings 12-storey 60000m2 group houses in the third-class area, including 3 40000m2 internally poured external houses and 2 20000m2 fully assembled wall panels. The inspection quota is 32- 17 and 32- 103, and the construction period is 25 and 2 1.5.
(25× 40000+21.5× 20000)/60000 = 24 months.
7. Unit
The provisions on the increase or decrease coefficient and days also apply to group housing projects, but they shall not be calculated according to the cumulative coefficient and days of each building.
8. The time limit for a single residential project in a group residential project is as follows
Assessment of planned construction period or contract construction period.
