Standardise specification writing, collaborate more effectively and keep project decisions clearly documented. NBS Chorus Pro helps practices create reusable standards, work securely with external teams and produce project information in the formats they need.
More than specification writing
Create consistent specifications
Turn your organisation’s knowledge, preferred clauses and proven approaches into reusable specification content. Help every team begin with a stronger foundation rather than starting from scratch.
Collaborate with project teams
Invite clients, consultants, contractors and other contributors into the specification process. Control who can view, comment on or edit content, while keeping feedback connected to the specification.
Maintain a clearer project record
Capture decisions, guidance and revisions within the specification itself. Make it easier to understand what changed, why it changed and what information was issued.
Share information your way
Create professionally branded specifications and export structured project information for different audiences, tasks and stages of delivery.
