Scope

The "General Specification for Masonry Structures" is now approved as the national standard, numbered GB55007-2021, and will be implemented from January 1, 2022. This specification is a mandatory engineering construction specification, and all provisions must be strictly implemented. The relevant mandatory provisions of the current engineering construction standards shall be abolished at the same time. If the relevant provisions in the current engineering construction standards are inconsistent with this specification, the provisions of this specification shall prevail. This specification is published on the website of the Ministry of Housing and Urban-Rural Development (www.mohurd.gov.cn), and is published by China Construction Publishing and Media Co., Ltd. organized by the Institute of Standards and Quotas of the Ministry of Housing and Urban-Rural Development.

Introduction

1. Overview of the mandatory engineering construction specification system

In order to adapt to the international technical regulations and technical standards, the Ministry of Housing and Urban-Rural Development has successively issued documents such as "Opinions on Deepening the Reform of Engineering Construction Standardization Work" since 2016, proposing the long-term goal of the government to formulate mandatory standards and social groups to formulate voluntary adoption standards. It has clarified the reform task of gradually replacing the scattered mandatory provisions in the current standards with full-text mandatory engineering construction specifications.

2. Specification types and system structure

The mandatory engineering construction specification system 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, covering five major elements such as the project scale, layout, functional performance and key technical measures. General specifications focus on the general technologies of various professions to achieve the functional requirements of engineering construction projects.

3. Detailed explanation of the five major factor indicators

Element category	Specific content	Guarantee target
Project scale	Specify the production or service capacity of construction projects, which is consistent with the level of economic and social development	Infrastructure systematization and efficiency improvement
Project layout	Industrial layout, site selection, overall design, general layout and coordinated technical requirements for construction projects	Improve the overall level of facility construction
Project function	Clarify the project composition and purpose, and determine the basic components	Achieve the expected effect
Project performance	Specify the construction level or technical level of the construction project, and clarify the requirements for quality, safety, energy conservation, etc.	High-quality development of urban and rural construction
Key technical measures	Key technical regulations for achieving project functions and performance requirements	Guarantee the goal of safe, green and smart development of urban and rural construction

4. Key points for the implementation of mandatory engineering construction specifications

Mandatory engineering construction specifications are mandatory and binding, and are the basic requirements for protecting people's lives and property safety, personal health and public interests. On the premise of meeting the specifications, relevant group standards and enterprise standards can be reasonably selected to optimize the project functions or reach a higher level.

5. Implementation suggestions and precautions

• Survey, design, construction, acceptance and other construction activities shall be carried out strictly in accordance with the requirements of the specifications
• For existing building renovation projects, the standards shall not be lower than those at the time of original construction
• The recommended standards shall be coordinated with the mandatory specifications, and the technical requirements shall not be lower than the standard level
• After the implementation of the specifications, the mandatory provisions in the current relevant standards shall be abolished and the specifications shall prevail
