Classifying Literature

Specifiers are inundated with product literature – hardcopy or digital – and it is essential that literature is correctly classified and dated to ensure correct storage and easy retrieval.   The date and classification code should usually be clearly visible on the front cover of the literature, and preferably, on the top right hand corner.

The main classification systems in use in the UK are CI/SfB, CAWS and UNICLASS.   The CI/SfB and CAWS classification systems are independent of each other and it may be necessary to include references to both on literature.   Where classification of electronic product information is required, the EPIC (Electronic Product Information Co-operation) classification system is widely used.   The more recently introduced UNICLASS system incorporates EPIC and combines both CI/SfB and CAWS, and is designed to comprehensively cover all sectors of the building and construction industry and to have a truly international usage.

If literature is CPD-rated (see Promotion & PR – CPD Certification and Marketing), this information should also be clearly indicated on the front cover.   In addition, any references to British and European Standards, building regulations and applicable accreditation schemes should be clearly stated inside the publication, since this will add to the authority of the product or service, and also provide valuable information.

Classification Systems
CI/SfB
CI/SfB is still a widely-used construction industry classification system in the UK, is commonly used throughout Europe, and occasionally it is found in use in other countries in the world.   This is the established system which accounts for its wide use, but was last updated in 1976 and is being superseded by UNICLASS, which was launched in 1997.   This transition is likely to take many years and it is expected that CI/SfB will remain in common use for the foreseeable future.

Note: CI/SfB stands for construction industry (CI) and the Swedish ’Samarbetskommitten for Byggnadsfragor’ (SfB), which roughly translates to the ‘Joint Working Committee for Construction Issues’.

UNICLASS
United Classification for the Construction Industry is the most recent classification system which has been developed by NBS on behalf of the CPIC (Construction Industry Project Information Committee) and is gradually being introduced throughout the industry.   As explained above, UNICLASS incorporates features from all the above classification systems, and benefits from up-to-date classification (product) headings, reflecting new industry terminology (e.g. the term ‘Atrium’ would not appear in the CI/SfB system).   UNICLASS is the classification system recommended by CPIC to comply with BS.1192:2007.   Details of the index may be found at the CPIC website.   In April 2013, CIPS released UNICLASS2 on a trial basis, which will, over time, replace UNICLASS (see below). 

UNICLASS2
The UNICLASS2 classification system, which provided a logical platform for Building Information Modelling (BIM), was launched in April 2013 for use and review in live projects.   UNICLASS2 remains freely available via the CIPC website, which, at the time, described the development as follows:  "UNICLASS2 offers a searchable application that provides unified tables for structured information at key levels including complexes, activities, spaces, entities, systems and work results.   Tables for other information sets will be added.   Replacing the current UK standard classification UNICLASS, UNICLASS2 has been developed, with full industry consultation, by the UNICLASS working group of the Construction Project Information Committee."

UNICLASS2 features increased scope, depth and consistency of information, covering all aspects and disciplines of the built environment, including infrastructure and process engineering.   The Chairman of the CPIC said, “For the first time ever, the UK has a unified classification system that can structure how construction project information is accessed, developed and maintained.   We want to ensure the system is constantly improved so if people can’t find what they are looking for, we want to know.”

UNICLASS2015
In 2015, a further development was announced with the release of UNICLASS2015, which, according to the CIPC website “is now cited in the UK National foreword to ISO 12006-2 Building construction – Organisation of information about construction works as the UK response to that International Standard.   This has the important effect of elevating its status from that enjoyed by previous versions of UNICLASS.”

Earlier, in 2014, CIPC passed its intellectual copyrights in UNICLASS and the development work for UNICLASS2 to the UK Government "for beneficial and government backed and financed development and completion for use with BIM".   This, in turn, resulted in the UNICLASS2015 classification within the BIM Toolkit published by NBS.

Whilst CPIC continues to answer questions about legacy versions of UNICLASS, enquiries about Uniclass 2015 should be referred to the NBS

CAWS
Common Arrangement of Work Sections for Building Works is only used in Britain and is designed to link the activities of the architect and other designated professionals involved in the same project by using the same reference code for each work section.

EPIC
Electronic Product Information Co-operation has been more recently introduced to classify electronic product data and literature, and to provide the framework for structuring product database driven indices.

Formats
Despite the now dominant use of digitally based sources of product and technical information, hardcopy literature still remains an important form of publication by specifiers referencing specific product data.   This may, and probably will, change in time, but not yet.   We have covered this topic in our construction literature design feature and specialists in the field, CDP, have contributed a comprehensive paper on the subject specifically to aid construction product manufacturers.   This is titled, 'Less paper, but not paperless... the continuing importance of good technical literature'.
