Scope & Contents

Libraries of pre-written specification clauses, guidance and manufacturer product information are written by our in-house team of industry specialists and updated regularly. Content is arranged by system, covering multi-discipline content, which means that a single logical project specification can be written in less time avoiding the risk of duplicated or conflicting content.

Content libraries for NBS Create

NBS Create has a choice of four regularly maintained content libraries: Architecture, Landscape, Services and Structure.

You can browse the contents of each of these sections from this page - jump to ArchitectureLandscape, Services, or Structure and expand each of the sub-sections by selecting the relevant title.
