Foreword
In order to adapt to the international technical regulations and the prevailing rules of technical standards, since 2016, the Ministry of Housing and Urban Rural Development has successively issued the Opinions on Deepening the Reform of Engineering Construction Standardization and other documents, proposing the long-term goal of the government to develop mandatory standards and social organizations to develop voluntary standards, and defining the reform task of gradually replacing the scattered mandatory provisions in the current standards with full text mandatory engineering construction specifications, Gradually form a "technical regulation" system consisting of technical provisions in laws, administrative regulations, departmental rules and full text mandatory project construction specifications.
About the types of specifications. The mandatory engineering construction specification system covers all kinds of construction projects in the engineering construction field, which is divided into two types: engineering project specifications (project specifications for short) and general technical specifications (general specifications for short). The project specification takes the overall engineering construction project as the object, and takes the project's scale, layout, function, performance and key technical measures as the main content. The general specification takes the general technology of all disciplines to meet the functional performance requirements of the engineering construction project as the object, and takes the general technical requirements of survey, design, construction, maintenance, maintenance, etc. as the main content. In the full text of the mandatory project construction specification system, the project specification is the backbone, and the general specification is the provision of common and common professional key technical measures for various projects.
About the five major factor indicators. The elements in the mandatory project construction specifications are the basic provisions to ensure the systematization and efficiency improvement of urban and rural infrastructure construction, and 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 should have a complete production or service capacity, and should adapt to the level of economic and social development. The layout requirements of the project mainly specify the industrial layout, construction project site selection, overall design, general layout and overall technical requirements in coordination with the scale. The reasonable distribution of supply capacity should be considered to improve the overall level of related facilities construction. The functional requirements of the project mainly specify the composition and purpose of the project, and define 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 specify the construction level or technical level of the construction project, reflect the applicability of the construction project, and specify the basic level of project quality, safety, energy conservation, environmental protection, livable environment and sustainable development. The key technical measures are the basic technical provisions for realizing the functional and performance requirements of the construction project, and the basic guarantee for implementing the development goals of urban and rural construction, such as safety, green, resilience, wisdom, livability, fairness and efficiency.
About the implementation of specifications. Compulsory project construction specifications have mandatory binding force and are intended to safeguard the safety of people's lives and property, human health, project safety, ecological environment safety, public rights and interests, as well as promote the conservation and utilization of energy resources, meet the regulatory baseline requirements in economic and social management, etc. The survey, design, construction, acceptance, maintenance, maintenance, demolition and other construction activities of engineering construction projects must be strictly implemented throughout the whole process, Among them, for the existing building reconstruction project (referring to not changing the existing use function), when the conditions are not available and it is really difficult to implement the current specifications, it should not be lower than the original construction standards. The recommended engineering construction standards supporting 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 should also be implemented in general. On the premise of meeting the project function, performance requirements and key technical measures specified in the mandatory project construction specifications, relevant group standards and enterprise standards can be reasonably selected to optimize or reach a higher level of project function and performance. Recommended engineering construction standards, group standards and enterprise standards shall be coordinated with the mandatory engineering construction specifications, and the technical requirements shall not be lower than the relevant technical level of the mandatory engineering construction specifications.
After the implementation of the mandatory engineering construction specifications, the mandatory provisions in the current relevant national standards and industrial standards for engineering construction shall be abolished at the same time. The mandatory provisions in the current local standards for engineering construction shall be revised in a timely manner and shall not be lower than the provisions of the mandatory engineering construction specifications. If the relevant provisions in the current project construction standards (including mandatory standards and recommended standards) are inconsistent with the provisions of the mandatory project construction specifications, the provisions of the mandatory project construction specifications shall prevail.
