The implementation and release will play a guiding role in the promotion and application of precast interior decoration in Hainan Province, further help the construction of precast building standard system in Hainan Province, and promote the development of the whole industrial chain of precast buildings.

Hainan Provincial Department of housing and urban rural development will promote the implementation of the standards through extensive publicity, publicity and implementation training, and issuance of supporting policy documents…

The relevant person in charge said that the standard fully takes into account the regional characteristics of Hainan Province and the development status and objectives of precast interior decoration, and guides the solution of the five major needs in the application of precast interior decoration projects in Hainan Province: system integration design, elimination of common quality problems, green health, high performance, intelligence and informatization.

The standard emphasizes the quality requirements at all stages of design, manufacturing and transportation, construction installation, project quality acceptance, use and maintenance, and requires the use of BIM Technology, Ensure the accuracy and quality traceability of parts and engineering information transmission.

It shall be prepared by sections in the process of design, production, transportation, installation, acceptance and maintenance of cast interior decoration components.

In terms of high performance, the standard puts forward design and construction methods and quality requirements for the performance indicators of major materials such as cast interior parts and equipment pipelines, as well as building structure stress, fire protection, energy conservation, sound insulation, sanitation and epidemic prevention, and puts forward inspection methods for corresponding performance requirements in the chapter of “project quality acceptance”, which is both instructive and practical.

It is understood that this standard is the first special standard for precast interior decoration in Hainan Province.

The standard is divided into 8 chapters: general provisions, terms, basic provisions, design, manufacturing and transportation, construction and installation, project quality acceptance, use and maintenance.

As an important part of the technical requirements of precast buildings, precast interior decoration is the only way for the high-quality development of the construction field, and it is also an important part of the promotion of precast buildings.

In terms of system integration design, the standard implements the design concept of systematization, integration and integration of precast interior decoration, coordinates the requirements of various disciplines, plans the needs of various stages, and relies on BIM (building information model) technology to realize the information management and professional cooperation in the whole process.

It is forward-looking, normative and practical.

In terms of intelligence and informatization, BIM Technology is required in the provisions of the standard in the stages of design, manufacturing and transportation, construction and installation, project quality acceptance, use and maintenance, and intelligent professional application is considered to realize integrated fine design, management traceability of part quality and production related information, simulation, guidance and management of the whole construction process, review, delivery and receipt of BIM design documents and electronic documents Establish the use and maintenance database of interior decoration components and other requirements, and implement the principle of “information management and intelligent application” of precast interior decoration.

In terms of green health, the standard requires that the quality of indoor thermal environment, light environment, sound environment and air environment be improved and improved through the use of energy-saving and green environmental protection materials and components, so as to reduce the impact of adverse environment on buildings, and implement green construction and other measures to achieve green health requirements.

In order to standardize the implementation of precast interior decoration projects of civil buildings, improve the performance and quality of precast interior decoration, and promote the transformation and upgrading of the construction industry, Hainan Provincial Department of housing and urban rural development recently issued Hainan provincial technical standard for precast interior decoration (hereinafter referred to as the standard), which will be implemented from August 1, 2022.

It is full and accurate, and defines the requirements for precast interior decoration in the stages of design, component manufacturing and transportation, construction and installation, project quality acceptance and use and maintenance.

In terms of eliminating common quality problems, the standard requires that the construction method of dry operation construction process be adopted on the site to solve the problems of many wet operations, poor construction accuracy, complex processes, long construction cycle, relying on the level of on-site workers and difficult to guarantee the construction quality on the traditional construction site.
