Uniclass1.4 Legacy Release

This is an archive version of an article from the CPIc website, which was closed in 2025. CPIc (the Construction Project Information Committee) was formed from representatives of the major industry institutions and was responsible for providing best practice guidance on the content, form and preparation of construction production information.

The Uniclass1.4 Legacy Release has been provided by the CPI – the Construction Project Information Committee, 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.

Uniclass1.4 is provided for ongoing projects underway which require the old system for reference.

A full pdf of the Uniclass1.4 legacy release is available for use at the link below:
