Trinity Construction
Recently, the Beijing Municipal Commission of Housing and Urban-Rural Development and the Beijing Municipal Commission of Planning and Natural Resources jointly issued the Notice on Regulating the Construction and Management of High-quality Commercial Residential Projects (Jing Jianfa [2021] No. 384). The "Notice" pointed out that in order to implement the requirements of building a world-class harmonious and livable city proposed in the "Beijing Urban Master Plan (2016-2035)" and improve the construction quality of Beijing's commercial housing projects, Beijing has put forward high-standard commercial housing construction requirements based on the people's sense of gain, including: minimum quality requirements and competitive high-quality residential construction plans (building quality). The minimum quality requirements are two-star green building standards, prefabricated buildings with an assembly rate of 60%, and solar photovoltaic or solar thermal systems; The high-quality residential construction scheme consists of six parts: green buildings, prefabricated buildings, ultra-low energy buildings, healthy buildings, livable technology applications and management models.
In order to standardize the construction and management of high-quality commercial residential projects and ensure the effective implementation of relevant content indicators, the "Notice" puts forward clear requirements for implementation standards, process control and organizational guarantees:

(5) Healthy buildings: should comply with the "Healthy Building Evaluation Standards" (T/ASC 02-2016) or the international WELL Building Standards; When a national, industry, or local standard for the implementation of healthy buildings is issued, it should be in line with the current standard.
(6) The livable technical content 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 process; The warranty period for the commitment quality of exterior wall insulation engineering, roof insulation engineering, waterproof engineering, and building doors and windows shall be specified in the commercial housing sales contract.
(7) The general contracting mode of the project shall be implemented in the process of project contracting.
(8) The architect responsibility system shall implement the "Guiding Opinions on the Pilot Project of the Beijing Architect Responsibility System" (Jing Gui Zi Fa [2021] No. 28), which gives the architect and the construction unit the right to jointly issue instructions, approve the project, and pay for the visa, and agree on it in the architect's service contract and implement it.
(9) Green building performance insurance should be implemented in the insurance contract.
(10) BIM technology should adopt forward design and comply with the Unified Standard for the Application of Building Information Modeling (GB/T 51212-2016), the Standard for the Design and Delivery of Building Information Modeling (GB/T 51301-2018), the Standard for the Application of Building Information Modeling in Construction (GB/T 51235-2017), the Standard for the Design of Civil Building Information Modeling (DB11/1063-2014), and the Standard for the Fineness of Modeling for the Detailed Design of Civil Building Information Modeling (DB11T1610-2018) and other current standards, and implement the relevant requirements of the "Implementation Opinions on the Application of BIM Technology in the Whole Life Cycle of Engineering Construction Projects".
2. Process control
The management of commercial housing projects is mainly based on the commitment of the construction unit, and all relevant departments strengthen supervision during and after the event.
(1) The project can carry out design bidding after signing the land transfer contract, and the project shall complete the project approval, approval or filing procedures before the general contracting of the project.
(2) Before the construction drawings are recorded, the construction unit shall organize an expert review meeting on the implementation plan, and invite the relevant departments of the Municipal Planning and Natural Resources Commission and the Municipal Housing and Urban-Rural Development Commission to participate in the expert review meeting. The implementation plan for high-quality residential construction shall provide relevant materials such as green building and healthy building self-assessment report, assembly rate calculation book, ultra-low energy consumption building self-evaluation form, and specific measures for the implementation of the architect's responsibility system according to the commitment.
(3) When applying for a construction permit, the construction unit shall fill in the relevant content of green buildings and prefabricated buildings in the construction permit system on the website of the Municipal Housing and Urban-Rural Development Commission.
(4) In the process of construction, the construction unit shall strictly follow the requirements of high-standard commercial residential construction for management, and implement the requirements of green buildings, prefabricated buildings, ultra-low energy consumption buildings, healthy buildings, livable technology applications, architect responsibility systems and other management modes according to the content of the commitment; If the construction drawing design document is changed and the commitment content is affected, the plan review should be reorganized. For projects that promise to apply BIM technology throughout the life cycle, the construction unit shall organize all parties involved in the construction to carry out the application of Building Information Modeling (BIM) in the planning, survey, design, construction, operation and maintenance stages, and shall do a good job in the delivery and application of the model at each stage; The visual model file delivered by the construction unit may also be provided to the property management unit, or the contract stipulates that the construction unit shall deliver the visual model file to the property management unit.
