工程建设标准化信息网CCSN（Construction Codes Standards National）是工程建设标准信息发布、技术管理、面向国际的工程建设标准化信息平台。
工程建设标准化信息网CCSN由住房和城乡建设部标准定额研究所主办，于2006年8月1日开始运行。自开通运行迄今，CCSN始终朝着工程建设标准化工作宣传和服务的国家级基础性工作平台的目标努力，为政府部门、技术管理单位、技术支撑机构、工程技术人员等提供信息服务，是13个全国标准化委员会和21个住房和城乡建设部标准化技术委员会共同开展标准技术管理的工作平台。CCSN提供工程建设标准化工作宣传和服务，开展工程建设国家、行业、地方等各层级标准全生命期的技术管理，进行标准数据智能化应用和统计，推进实现标准数据数字化管理和智能化应用。
The Engineering Construction Standardization Information Network (CCSN, Construction Codes Standards National
) is a standardized information platform for engineering construction standards information dissemination, technical management, and internationally oriented engineering construction.
CCSN is sponsored by the Research Institute of Standards and Norms (RISN) of the Ministry of Housing and Urban Rural Development (MOHURD), and began operation on August 1, 2006. Since its opening and operation, CCSN has always been working towards the goal of being a national level basic work platform for promoting and serving standardization work in engineering construction. It provides information services for government departments, technical management units, technical support institutions, engineering and technical personnel, and is a working platform for ISO Technical Committee centralized management by MOHURD, 13 national standardization committees and 21 standardization technical committees of MOHURD to jointly carry out standard technology management.
CCSN provides publicity and services for standardization work in engineering construction, international exchange and research on engineering construction standards, carries out technical management for the entire lifecycle of national, industry, local and other levels of standards in engineering construction, conducts intelligent application and statistics of standard data, and promotes the realization of digital management and intelligent application of standard data.
