Different NBS Building libraries provide preliminaries, work sections and guidance suited to certain types of work. The libraries are Standard, Intermediate and Minor Works, and are offered in the following combinations:

Full Service

Standard, Intermediate and Minor Works.

For projects of any size. The Standard work sections include performance-based clauses, which are suitable for design and build contracts as well as traditional procurement. They are also accompanied by extensive guidance notes.

Abridged

Intermediate and Minor Works.

For more simple, medium sized projects. Scope is comprehensive but sections have been edited to suit the scale of work envisaged, and guidance is less extensive.

Minor Works

For small scale works where brevity is important. There are fewer sections, which are edited for small jobs.
