Interpreting the content of the preface to the General Code for Building Electrical and Intelligent Systems

Thread Content

The mandatory standard for the entire text, the \"General Code for Building Electrical and Intelligent Systems\" GB 55024-2022, came into effect on October 1, 2022! This article shares the preface of the \"General Specifications for Building Electrical Systems and Intelligence\", which contains a great deal of information and presents clear explanations and requirements. 1. Status: The existing scattered mandatory provisions in current standards shall be gradually replaced by comprehensive mandatory construction codes, so as to gradually establish a \"technical regulation\" system composed of laws, administrative regulations, technical provisions in departmental rules, and comprehensive mandatory construction codes. 2. Types of standards: The mandatory engineering construction standard system is divided into project-specific standards, abbreviated as project standards ； and general technical specifications, referred to as general specifications. Project specifications focus on the entire engineering construction project as a whole, with the five key elements of project scale, layout, function, performance, and key technical measures as their main content ； General specifications address the common technologies across various specialties required to meet the functional and performance demands of engineering construction projects, with the general technical requirements for surveying, design, construction, maintenance, and upkeep as their main content. The \"General Code for Building Electrical and Intelligent Systems\" GB 55024-2022 is a general technical code. Within the entire system of mandatory engineering construction codes, project-specific codes serve as the core, while general codes specify the common and universal professional technical measures applicable to various types of projects.

Five key elements: The various elements outlined in the mandatory engineering construction standards serve as the basic regulations for ensuring a systematic approach to urban and rural infrastructure development as well as improving efficiency; they represent the fundamental requirements for promoting high-quality development in urban and rural construction. ①The scale requirements for projects mainly stipulate that construction projects should possess complete production or service capabilities and should be in line with the level of economic and social development. ②The layout requirements for the project mainly specify the industrial layout, the site selection for construction projects, the overall design, the general plan layout, as well as comprehensive technical requirements that are in line with the scale of the project. It is necessary to consider a reasonable distribution of supply capacity in order to improve the overall quality of the construction of related facilities. ③The functional requirements of a project mainly specify its composition and purpose, define its basic constituent units, and serve as a guarantee for the project to fulfill its intended functions. ④The performance requirements for a project primarily specify the level of construction quality or technical standards for that project, reflecting its suitability. They establish the basic standards that must be met in terms of project quality, safety, energy efficiency, environmental protection, habitability, and sustainable development. ⑤Key technical measures are the basic technical specifications for meeting the functional and performance requirements of construction projects, and they serve as the fundamental guarantee for achieving development goals such as safety, sustainability, resilience, intelligence, habitability, fairness, and efficiency in urban and rural construction. 4. Standardized implementation: Mandatory engineering construction standards are binding in nature; they represent the minimum requirements necessary to safeguard people’s lives and property, their health, the safety of engineering projects, the integrity of the ecological environment, as well as the rights and interests of the public. They also serve to promote the efficient use of energy and resources and to support effective economic and social management. These standards must be strictly followed throughout the entire process of engineering construction projects, including investigation, design, construction, inspection, maintenance, repair, and demolition. The recommended engineering construction standards that complement the mandatory engineering construction codes are mature technical measures proven through practice to ensure compliance with the requirements of the mandatory codes, and they should generally also be implemented. On the premise of meeting the functional, performance requirements, and key technical measures specified in the mandatory engineering construction codes, relevant industry standards and corporate standards can be appropriately adopted to further optimize the functions and performance of the project or raise them to a higher level. Recommended engineering construction standards, group standards, and enterprise standards shall be coordinated and compatible with mandatory engineering construction codes; all technical requirements must not be lower than the relevant technical levels stipulated in the mandatory engineering construction codes. Following the implementation of the mandatory engineering construction codes, the mandatory provisions in the current relevant engineering construction **standards and industry standards are simultaneously repealed. The mandatory provisions in the current local standards for engineering construction should be revised in a timely manner, and shall not be lower than the requirements of the mandatory engineering construction codes. Where the relevant provisions in the current engineering construction standards (including mandatory and recommended standards) are inconsistent with those in the mandatory engineering construction codes, the provisions of the mandatory engineering construction codes shall prevail. Therefore, this year’s National Day marks a new beginning for electrical professionals; they must diligently study and implement the “General Code for Electrical and Intelligent Systems in Buildings”!
