Page 4 of 22GB 55007-2021 Foreword In order to adapt to the prevailing rules of international technical regulations and technical standards, since 2016, the Ministry of Housing and Urban-Rural Development has successively issued documents such as Opinions on Deepening the Reform of Engineering Construction Standardization Work, proposing the long-term goal that the government formulate mandatory standards and social organizations formulate voluntary standards. The long-term goal is to clarify the reform task of gradually replacing the scattered mandatory provisions in the current standards with the full-text mandatory engineering construction specifications; and gradually form a “Technical Regulations” system composed of laws, administrative regulations, technical provisions in departmental rules and full-text mandatory engineering construction specifications. Regarding the specification category. The mandatory engineering construction specification system covers various construction projects in the field of engineering construction; and is divided into two categories: engineering project specifications (referred to as project specifications) and general technical specifications (referred to as general specifications). The project specification takes the entire engineering construction project as an object; and takes the five elements of the project scale, layout, function, performance and key technical measures as the main content. The general specification takes the general technology of various specialties to realize the functional performance requirements of engineering construction projects as an object; and takes the general technical requirements such as survey, design, construction, repair, maintenance, etc. as the main content. In the full-text mandatory engineering construction specification system, the project specification is the backbone; and the general specification is the regulation of common and general professional key technical measures for various projects. Regarding the five major elements of indicators. The various elements in the mandatory engineering construction specifications are the basic provisions to ensure the systematization and efficiency improvement of urban and rural infrastructure construction; and are the basic requirements to support the high-quality development of urban and rural construction. The scale requirements of the project mainly stipulate that the construction project shall have complete production or service capabilities; and shall adapt to the level of economic and social development. The layout requirements of the project mainly stipulate the industrial layout, construction project site selection, overall design, general layout and overall technical requirements coordinated with the scale; reasonable distribution of supply capacity shall be considered to improve the overall level of related facility construction. The functional requirements of the project mainly stipulate the composition and use of the project; and clarify the basic constituent units of the project, which is the guarantee for the project to play its expected role. The performance requirements of the project mainly stipulate the construction level or technical level of the construction project; reflect the applicability of the construction project; and clarify the basic level that shall be achieved in terms of project quality, safety, energy saving, environmental protection, livable environment, and sustainable development. Page 5 of 22GB 55007-2021 The key technical measures are the basic technical regulations to realize the functions and performance requirements of the construction project; and are the basic guarantee for the implementation of the development goals of urban and rural construction such as safety, greenness, resilience, wisdom, livability, fairness, and efficiency. Regarding implementation of the specification. Mandatory engineering construction specifications are mandatory and binding; and are the control bottom line requirements to protect people's life and property safety, personal health, engineering safety, ecological environment safety, public rights and interests, and promote the economical utilization of energy resources and meet economic and social management. The survey, design, construction, acceptance, repair, maintenance, demolition and other construction activities of engineering construction projects must be strictly implemented in the whole process. Thereof, for the existing building renovation project (indicating not changing the use functions), if it is really difficult to have and implement the current code due to the insufficient conditions, it shall be no lower than the original construction standard. The recommended engineering construction standards that are matched with the mandatory engineering construction specifications are mature technical measures that have been tested in practice to ensure that the requirements of the mandatory specifications are met; and shall be implemented under normal circumstances. Under the premise of meeting the project function, performance requirements and key technical measures stipulated in the mandatory engineering construction specifications, relevant group standards and enterprise standards can be reasonably selected to optimize the project function and performance or reach a higher level. The recommended engineering construction standards, group standards, and enterprise standards shall be coordinated with the mandatory engineering construction specifications; and each of the above-mentioned technical requirements shall be no lower than the relevant technical level of the mandatory engineering construction specifications. After the mandatory engineering construction specifications are implemented, the mandatory provisions in the current relevant national engineering construction standards and industry standards shall be abolished simultaneously. The mandatory provisions in the current local engineering construction standards shall be revised in time; and shall be no lower than the provisions of the mandatory engineering construction specifications. If the relevant provisions in the current engineering construction standards (including mandatory standards and recommended standards) are inconsistent with the provisions of the mandatory engineering construction specifications, the provisions of the mandatory engineering construction specifications shall prevail.
