"Technical regulations" system.
Regarding normative categories. The mandatory engineering construction specification system covers all types of construction projects in the field of engineering construction and is divided into two types: engineering project specifications (referred to as project specifications) and general technical specifications (referred to as general specifications). Project specifications take the entire engineering construction project as the object, and take the five major elements of the project as scale, layout, function, performance and key technical measures as the main content. The general specifications target the general technologies of various professions that realize the functional performance requirements of engineering construction projects, and take general technical requirements such as survey, design, construction, repair, and maintenance as the main content. In the full-text mandatory engineering construction specification system, project specifications are the backbone, and general specifications are regulations on common and common professional key technical measures for various projects.
About the five major factor indicators. The various elements in the mandatory engineering construction specifications are the basic regulations 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 project scale requirements mainly stipulate that the construction project should have complete production or service capabilities and should be compatible with 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 that are coordinated with the scale. Reasonable distribution of supply capacity should be considered to improve the overall level of related facility construction. The functional requirements of the project mainly stipulate the project composition and purpose, and clarify the basic component 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 level of construction or technical level of the construction project, reflect the applicability of the construction project, and clarify the basic levels that should be achieved in terms of project quality, safety, energy saving, environmental protection, livable environment and sustainable development. . Key technical measures are the basic technical regulations for realizing the function and performance requirements of construction projects, and are the basic guarantee for the implementation of development goals such as safe, green, resilient, smart, livable, equitable, and efficient urban and rural construction.
Regarding the implementation of standards. Compulsory engineering construction regulations are mandatory and binding. They are the control bottom line for ensuring the safety of people's lives and property, personal health, project safety, ecological environment safety, public rights and interests, promoting the conservation and utilization of energy resources, and satisfying economic and social management. Requirements, the entire process of construction activities such as survey, design, construction, acceptance, repair, maintenance, and demolition of engineering construction projects must be strictly implemented. Among them, for existing building renovation projects (meaning that the existing use functions will not be changed), when the conditions do not When it is really difficult to meet and implement the current specifications, the standards should not be lower than those at the time of original construction. The recommended engineering construction standards supporting the mandatory engineering construction specifications are mature technical measures that have been tested in practice and ensure that the requirements of the mandatory specifications are met, and should also be implemented under normal circumstances. On the premise of meeting the project functions, 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 functions and performance or reach a higher level. Recommended engineering construction standards, group standards, and enterprise standards must be coordinated and matched with the mandatory engineering construction specifications, and the technical requirements must not be lower than the relevant technical level of the mandatory engineering construction specifications.
After the implementation of the mandatory engineering construction regulations, the mandatory provisions in the current national standards and industry standards for relevant engineering construction will be abolished at the same time. The mandatory provisions in the current local standards for engineering construction should be revised in a timely manner and should not be 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 compulsory engineering construction specifications, the provisions of the compulsory engineering construction specifications shall prevail.
