OrumaSpec is a CAWS specification tool for small UK architecture practices. It covers the job that would otherwise need NBS Chorus, and it is a structured alternative to hacked Word systems. A living clause library helps you stay on top of the latest standards.

How much does OrumaSpec cost?

OrumaSpec is £15 per month per organisation, with 5 seats included, plus a £195 project credit when you start a live specification. The project credit can sit in the client’s architectural fee, so the practice overhead is the monthly organisation fee.

Is OrumaSpec an NBS Chorus alternative?

Yes, for small UK architecture practices writing CAWS specifications. OrumaSpec covers that job without an enterprise subscription.

Does OrumaSpec replace Word?

It replaces hacked Word-and-folder specification systems with a structured CAWS workflow, office templates, and a living clause library. You still issue a professional spec; you do not stay in ad-hoc documents.

Fee proposal tip: include Oruma within your project-specific software / specification production allowance when agreeing your architectural fee. Because the main cost is linked to a specific project, it can sit in the fee proposal rather than as a general annual overhead.

Your NBS Chorus figure

Scales with seats. Edit the figure if your NBS Chorus quote is different.
