CI/SfB

CI/SfB stands for the Construction Index/SfB classification system. It is a classification system developed for organizing and retrieving information relating to the construction industry, commonly used in the United Kingdom and other regions.

Originally, CI stood for "Construction Index," a printed index of construction products and services. SfB stands for Samarbetskommittén för Byggnadsfrågor (Co-ordinating Committee for Building Questions), a Swedish committee that developed the original classification system. The system was later adapted and integrated with the Construction Index.

CI/SfB provides a hierarchical, faceted classification system that allows construction professionals to categorize documents, drawings, products, components, and other information related to building projects. It uses a combination of numbers and letters to create unique codes for each category. The system aims to provide a standardized method for organizing and retrieving information, facilitating better communication and collaboration within the construction industry.

The CI/SfB system has been revised and updated over the years. It is used in various applications, including libraries, product catalogues, and project management systems, as a tool for information organization and retrieval related to construction. While it has been largely superseded by more modern classification systems in some areas, it remains relevant in specific sectors and legacy applications within the construction industry. The standard allows users to classify elements of a construction project based on form, function, materials, and location.
