ISO 12006

ISO 12006 "Building construction - Organization of information about construction works" is an international standard dealing with structuring of information for construction. It is composed of two parts:

  • ISO 12006-2:2015 "Building construction - Organization of information about construction works - Part 2: Framework for classification of information" more details in:
  • ISO 12006-3:2007 "Building construction - Organization of information about construction works - Part 3: Framework for object-oriented information" also known as buildingSMART Data Dictionary or International Framework for Dictionaries (IFD) Library.

Classification of project stages:

  • inception/ procurement
  • feasibility
  • outline proposals, programme preparation
  • scheme detail/ costing
  • detail design/ costing
  • production information and bills of quantities preparation
  • tender action
  • construction preparation
  • construction operations on site
  • completion
  • feedback

Construction Specifications Institute

The Construction Specifications Institute (CSI) is a national association of more than 8,000 construction industry professionals who are experts in building construction and the materials used therein. The Institute is dedicated to improving the communication of construction information through a diversified membership base of allied professionals involved in the creation and management of the built environment, continuous development and transformation of standards and formats, education and certification of professionals to improve project delivery processes, and creation of practice tools to assist users throughout the facility life-cycle. The work of CSI is currently focused in three areas:

Standards and publications

Construction industry professional certifications

Continuing education for construction professionals

List of International Organization for Standardization standards, 12000-13999

This is a list of published International Organization for Standardization (ISO) standards and other deliverables. For a complete and up-to-date list of all the ISO standards, see the ISO catalogue.The standards are protected by copyright and most of them must be purchased. However, about 300 of the standards produced by ISO and IEC's Joint Technical Committee 1 (JTC1) have been made freely and publicly available.


Uniclass 2015 is a unified classification system for all sectors of the UK construction industry. It contains consistent tables classifying items of all scales, from facilities such as a railway to products like anchor plates, flue liners or LED lamps.

Originally released in 1997, Uniclass allows project information to be structured to a recognised standard. This original version has now been heavily revised, to make it more suitable for use with modern construction industry practice, and to make it compatible with BIM (Building information modeling) now and in the future.

Led by the National Building Specification (NBS), experts from across the industry have developed the new system, known as Uniclass 2015. This significantly extends the scope of the previous version, and responds to industry feedback on the draft tables known as Uniclass 2, published by CPI in 2013.

Uniclass 2015 provides:

A unified classification system for the construction industry. For the first time, buildings, landscape and infrastructure can be classified under one unified scheme

A hierarchical suite of tables that support classification from a university campus or road network to a floor tile or kerb unit

A numbering system that is flexible enough to accommodate future classification requirements

A system compliant with ISO 12006 that is mapped to NRM1 and supports mapping to other classification systems in the future

A classification system that will be maintained and updated by NBS.
