The construction industry does not have the title of "massive building". And "large-scale building" should be called large-scale construction project or large-scale construction project;

Low-rise, multi-storey and high-rise buildings are divided according to the natural floors above the ground and the building height.

First, large-scale projects (construction projects) are divided according to project investment, single building area, building height, building complexity and the degree of influence on society and public life;

Scale division of large-scale construction projects (construction projects): (extracted from the engineering design qualification standard of the Ministry of Housing and Urban-Rural Development for reference)

1 General single building area is more than 20000 m2/ building height is more than 50m；;

2 large-scale public building projects, small and medium-sized public building projects in provinces (cities) with complex technical requirements or economic, cultural and historical significance;

3. It is equivalent to the standard interior decoration and special acoustic decoration project of four-star and five-star hotels;

4. High standard ancient buildings, protective buildings and underground construction projects;

5. High-standard architectural environment design and outdoor engineering;

6. Industrial workshops with complex technical requirements;

7 residential dormitory floors > 20 floors;

8. Planning and design of the factory living area with a total construction area of > 300,000m2 in the residential area;

9 underground space (total construction area) >10000m2;

10 with civil air defense (protection level) level 4 and above;

Two. General Principles for Civil Building Design (GB50352-2005) (excerpt)

3. 1.2 The classification of civil buildings according to the number of floors or height above the ground shall meet the following requirements:

1 Houses are classified by floors: the first to third floors are low-rise houses, the fourth to sixth floors are multi-storey houses, the seventh to ninth floors are medium-high-rise houses, and the tenth and above floors are high-rise houses;

Except residential buildings, civil buildings with a height of no more than 24m are single-storey and multi-storey buildings, and those with a height of more than 24m are high-rise buildings (excluding single-storey public buildings with a building height of more than 24m);

3. Civil buildings with a building height greater than 100m are super high-rise buildings.

Note: The calculation of building floors and building heights in this article shall comply with the relevant provisions of the fire protection code.

Three. Code for fire protection design of buildings (GB 500 16-20 14).

5. 1. 1 Civil buildings are divided into single-storey and multi-storey civil buildings and high-rise civil buildings according to their building height and floors. High-rise civil buildings can be divided into one category and two categories according to their building height, use function and occupied area. . The classification of civil buildings shall conform to Table 5. 1. 1.
