The Uniclass2 Development Release Classification Tables are provided through the CPI - the Construction Project Information Committee (www.cpic.org.uk), who are responsible for providing best practice guidance on the content, form and preparation of construction production information, and making sure this best practice is disseminated throughout the UK construction industry.
This tool is a fully searchable, online version of the following ten Uniclass2 Development Release Classification tables (to find out how to use this tool see the FAQ):
A full PDF version of these eleven tables is available here: 2013-12-03_Uniclass2(Development Release).pdf
A classification system is an essential tool for organising information. Without an agreed, comprehensive system for organising construction information it will be impossible to ensure interoperability between different information systems, design tools, and facilities management tools, with data entered once and re-used several times through the process.
A construction classification system must include buildings, infrastructure and integrated project and office management. It must be able to map project information from the initial concept through brief, detailed design, construction, handover and facility operation and maintenance. To fully adopt the BIM process it is important to organise such information systematically and consistently.
Uniclass 2 has been developed to produce a classification system for structuring information that is freely available for all participants throughout the life cycle of a project and beyond, which is endorsed by all construction and property bodies and professional institutions. It is dynamic, available online in various formats and managed by a team of experts who will monitor requests, update and control versioning. The tables available in this tool are ready for use in applications to test their usability. Where missing classifications are identified they should be notified to the CPI Committee Secretary Sarah Delany directly at sarah@cpic.org.uk so that they can be added centrally for all to use.
A: To find the code for Bell Ringing, or indeed any specific term, you can use the 'Search Uniclass2' box at the top right of the table. Start typing the term you require (in this example, start typing 'Bell'), and the tool will begin filtering down the tables to contain only item codes which mention that term.
A: At the foot of the table is a set of search box which lets you filter out the codes you don't want. To show only a specific table, for instance the Systems (Ss) table, type the table name or appropriate code (in this case 'Ss' or 'Systems') in the box at the foot of the Table column (where it says 'Search by Table'). This will filter out all the codes that are not part of the Systems (Ss) table.
A: You can combine multiple searches in the Uniclass2 tool. For instance, if you want to find a term containing 'office' only in the Entities (En) table, type 'Office' into the 'Search Uniclass2' box at the top right of the table, then filter out the table you do not want by entering 'En' or 'Entities' in the 'Search by Table' box at the foot of the table column.
A: Uniclass2 is organised in a hierarchical tree-like structure, with each term having a 'parent/child' relationship to a more general term higher up that tree. This column shows the broader classification term for each item.
A: You can export the results of your searches using the Copy, CSV, PDF and Print buttons at the top right of the table. You could even download the full set of tables themselves, but please be aware that exporting a PDF of the full Uniclass2 System in some browsers may take a while! A previously generated version of the full Uniclass2 System is available here: 2013-08-25_Uniclass2(Development Release).pdf
A: The tool displays 10 Uniclass2 items per page by default. You can flip through these pages using the buttons at the bottom right of the table (First, Previous, 1,2,3,4,5, Next, Last).
To display more than 10 items per page, select another value from the drop-down list at the top left of the table, where it says 'Show X Entries', where X is the number of entries to show (up to 100 per-page).
A: The Uniclass2 tables will evolve and be revised at regular intervals to incorporate feedback and comments. Work has started on preparing further Uniclass2 tables to cover management information (the previous Uniclass tables A, B and C) as well as materials, properties and characteristics (the previous Uniclass tables M, N and P). These will be made available for comment on the CPI website and through the CPI/Uniclass LinkedIn Group.
A: The best way to request a change or fix to the Uniclass2 Development Release tables is to email the CPI Committee secretary, Sarah Delany, directly at sarah@cpic.org.uk
A: ISO 12006-2 is an international standard dealing with structuring of information for construction, and is the standard to which Uniclass2 is aligned.
ISO 12006-2 Building construction - Organization of information about construction works - Part 2: Framework for classification of information, sets out the need for standardization in the construction industry: "Modern information systems for the construction industry, whether local or networked, need to handle data of many different types, e.g. geometrical data, technical properties, cost data, maintenance data, for use within different applications such as CAD, specification, product information and cost information systems. All these data and the relations between them need to be defined and structured in such a way that the stored information is consistent and reliable within and between the different applications."
A: In general, the following mappings hold between Uniclass2 and the previous Uniclass:

The original Uniclass2 Beta search tool was a development from the BIM Gateway, a collaborative project between the RIBA Technical Research Department and the University of the Arts London. The project was co-funded by the government-backed Technology Strategy Board “Metadata Production Tools (Fast Track)” funding stream.
