Clauses, guidance and product information are updated regularly. When you use NBS Building, the software will let you know if you are using the most up-to-date information. If updated material is available, it will prompt you to access it.

Produce professional specifications

NBS Building contains pre-written technical specification clauses and preliminaries for selection and editing to produce project specifications. Clauses are authored by our team of in-house architects and surveyors to be concise and robust, and are arranged in accordance with the Common Arrangement of Work Sections (CAWS).

Some clauses require additional information, which you can either type in or complete with the use of drop-down lists of suggested solutions. Clauses are provided for both prescriptive and performance specification.

Less time specifying

Specifications are produced with speed and accuracy by removing clauses not relevant to the project from a pre-authored list and using the drop-down menus to add project-specific content.
