Green Building Specification Navigation
Introduction:


This list is based on 1987 Committee for Coordinated Project Information (CCPI)’s Common Arrangement of Work Sections (CAWS) however over decades of project specification writing BrianSpecMan found their list insufficient in some areas.

Some methods of construction warrant separating out of work sections e.g. Z11 and G20 needs subdivision:

The following list of work section reflects the total list from GBE, GBS, ASWS, NGS and BrianSpecMan‘s >37 years of specification writing practice and £2420m project value track record.

In addition specifications are also available on a GBE Page or in the GBE Shop are listed below.

In addition many more specifications are written but not added or linked here

Contact NGS GBS if you would be interested is seeing them

Each work section one could consider adding an appendix for:

  • Manufacturers & Suppliers
  • Installers & Applicators
  • Service providers
