The project shall complete the project approval, approval or filing procedures before the EPC contract.

In order to standardize the construction management of high-quality commercial housing projects and ensure the effective implementation of relevant contents and indicators, the relevant requirements are hereby notified as follows: I.

（10） BIM Technology shall adopt positive design and comply with unified standard for application of building information model (GB / t51212-2016), standard for design and delivery of building information model (GB / t51301-2018), standard for construction application of building information model (GB / t51235-2017), standard for design of civil building information model (DB11 / 1063-2014) Current standards such as the standard for modeling fineness of civil building information model deepening design (db11t1610-2018), and implement the relevant requirements of the opinions on the implementation of BIM Technology Application in the whole life cycle of engineering construction projects.

Process control commercial housing project management is mainly based on the commitment of the construction unit, and all relevant departments strengthen the supervision during and after the event.

Precast buildings may not be used for new public buildings, structures of construction projects and supporting ancillary facilities (garbage room, power distribution room, etc.) with a single building area of less than 5000 square meters.

384, district housing and urban rural development commissions (housing administration bureaus), Dongcheng, Xicheng and Shijingshan District Housing and urban construction commissions, district planning and natural resources bureaus All relevant units: in order to implement the requirements for building a world-class, harmonious and livable city proposed in the Beijing urban master plan (2016-2035) and improve the construction quality of commercial housing projects in our city, our city puts forward the requirements for the construction of high-standard commercial housing based on the sense of people’s access, Including minimum quality requirements and competitive high-quality residential construction scheme (construction quality).

The minimum quality requirements are two-star green building standards, precast buildings with an assembly rate of 60%, and solar photovoltaic or photothermal systems; The high-quality housing construction scheme consists of six parts: green building, precast building, ultra-low energy consumption building, healthy building, livable technology application and management mode.

Recently, the official website of Beijing Municipal Commission of housing and urban rural development issued the notice on standardizing the construction and management of high-quality commercial housing projects, which regulates the implementation standards, control process and organizational guarantee of high-standard housing construction.

implementation standard (I) green building: it shall comply with the current standards such as the evaluation standard for green buildings (GB / t50378-2019) and the evaluation standard for green buildings (DB11 / t825-2021) of Beijing.

28), give the architect and the construction unit the right to jointly issue instructions, approve the project and visa payment, which should be agreed in the architect service contract and implemented.

（7） The general contracting mode of the project shall be implemented in the project contracting link.

（2） Precast buildings: they shall comply with the current standards such as the evaluation standard for precast buildings (DB11 / t1831-2021) and the code for residential design (db111740-2021).

（1） After signing the land transfer contract, the project can carry out design bidding.

（4） Ultra low energy consumption buildings: residential buildings shall comply with the design standard for ultra low energy consumption residential buildings (DB11 / t1665-2019); Public buildings shall comply with the current standards such as the technical guidelines for ultra low energy consumption demonstration projects in Beijing (JJF [2018] No.

（6） The content of livable technology should be implemented in the design documents such as drawings, among which the application of green building materials should also be implemented in the construction material selection link; The warranty period of exterior wall thermal insulation works, roof thermal insulation works, waterproof works and building doors and windows shall be specified in the commercial housing sales contract.

The original text of the notice is as follows: Notice on standardizing the construction and management of high-quality commercial housing projects, JJF [2021] No.

II.

（3） When handling the construction permit, the construction unit shall fill in the relevant contents of green building and precast building in the construction permit system on the website of the Municipal Commission of housing and urban rural development..

（9） Green building performance insurance shall be implemented in the insurance contract.

183).

（8） The architect responsibility system should implement the guidance on the pilot of Beijing architect responsibility system (jingguizi Zi Zi Zi [2021] No.

（2） Before the filing of construction drawings, the construction unit shall organize an expert review meeting for the implementation scheme, and invite relevant departments of the Municipal Commission of planning and natural resources and the Municipal Commission of housing and urban rural development to participate in the expert review meeting.

（5） Healthy building: it shall comply with the evaluation standard for healthy buildings (T / asc02-2016) or the international well building standard; When issuing national standards, industrial standards or local standards for the implementation of healthy buildings, they shall comply with the current standards.

（3） Solar photovoltaic or photothermal: residential buildings shall comply with the design standard for energy efficiency of residential buildings (DB11 / 891-2020), and public buildings shall comply with the current standards such as the design standard for energy efficiency of public buildings (DB11 / 687-2015).

The implementation plan of high-quality residential construction shall provide relevant materials such as the self-evaluation report of green buildings and healthy buildings, the calculation sheet of assembly rate, the self-evaluation form of ultra-low energy consumption buildings, and the description of specific measures for implementing the architect responsibility system.

For example, the minimum quality requirement is the two-star standard of green building, the precast building is adopted, and the assembly rate reaches 60%, and the solar photovoltaic or photothermal system is set; The high-quality housing construction scheme consists of six parts: green building, precast building, ultra-low energy consumption building, healthy building, livable technology application and management mode.
