"Guidelines for Fire Design (2022)" here

In order to regulate and clarify the existing construction of fire protection design and review work, and ensure the existing construction fire safety, the Chengdu Housing and Construction Bureau issued the "Guide to Chengdu's existing architectural reconstruction engineering fire design guide (2022)" (hereinafter referred to as the "Guidelines" ), Guidance has been put forward on how to apply new and old fire standards in the form of different buildings.

Which existing architectural renovation project applies this guide?

The "Guide" clearly states that the completion of the completion of the project and put into use or obtained the use of housing property rights in accordance with the law, and the transformation and design and use function transformation of housing property rights is a applicable scope for the factory and warehouse transformation of civil buildings.

The reconstruction of residential buildings, temporary buildings, villagers' self -built houses, and public buildings is not applicable to the transformation of factories and warehouses. Cultural relics protection units, historical architecture, historical and cultural block reconstruction projects organize expert arguments in accordance with the principle of "one matter" in accordance with the principle of "one thing and one discussion".

Is there a form of transformation of architecture?

The "Guide" states that both building transformation is divided into four forms: building internal decoration, building facade reconstruction, overall building reconstruction, and local renovation of the building.

Internal decoration refers to the function of not changing the building design and use function, does not change the main structure, load -bearing wall, and does not change the division of the fire prevention district, the form of evacuation stairs, the location and width of the evacuation aisle, etc. In order to meet the needs of the use, Protection and fixed facilities installation. The facade reconstruction refers to the decoration and renovation project of only the facade of the building. The overall transformation refers to the all -ground and underground transformation of monomer buildings, all the transformation above ground, and all transformation projects of single -building basement. Local transformation refers to the transformation projects other than internal decoration, facade reconstruction, and overall transformation.

Is the work that needs to be carried out before the reconstruction of the building?

The "Guide" states that before the renovation of architecture, it is transformed into special functional places (transformed into medical buildings, elderly care facilities, childcare children, kindergarten children's rooms, children's play halls and other children's activity venues and public gathering places. In the venue), the construction unit shall carry out the feasibility assessment of fire technology by themselves or the design unit and fire technology service agency, and the renovation into other types of places is encouraged and implemented.

Are the applicable principles of both new and old fire standards?

The existing construction transformation shall implement the current fire protection technical standards. When there is indeed difficulty due to conditions, it shall be implemented in accordance with the relevant technical requirements of this guide, and strive to improve and improve the level of construction fire safety.

Are there any problems and solutions to the technical requirements and solutions of architectural transformation?

The "Guide" clearly states that for the four different types of transformation, if the building design and use functions have not changed, 15 technical requirements have been proposed; if the building design and use functions have changed, 16 technical requirements are proposed, and the transformation is particularly emphasized to be transformed into special functional places for special use functional places. The existing architectural transformation must implement the current standard;

"Guide" in total plane layout, fire prevention partition and plane layout, safe evacuation and evacuation, fire supply facilities, smoke -proof facilities, fire electricity and power distribution, automatic fire alarm system and fire linkage control system, emergency lighting and evacuation instructions In terms of systems, 27 fire performance compensation measures were proposed. When the existing building transformation is restricted by the actual venue or the building itself, the current fire specifications and standards will be applied. The cost of transformation may be too high, the structure is safely damaged, and even a large number of buildings cannot implement the transformation.
