Libraries of pre-written specification clauses, guidance and manufacturer product information are authored by our multi-disciplinary specialist team.
NBS Chorus covers multi-discipline content, which means that an accurate specification can be written in less time, avoiding the risk of duplicated or conflicting content.
NBS Chorus covers the specific systems and the performance, products, execution and system completion clauses that are required by the following groupings. This content is grouped into four content libraries: Architecture, Landscape, Services and Structure.
