Industry Standards

BSRIA (Building Services Research and Information Association) broadly classify manuals into four groups according to the size and complexity of projects; Class A, B, C & D.

Class A
Basic record drawings and manufacturers’ literature or manuals.

Class B
Record drawings, manufacturers’ operating instructions, user manuals, test certificates and parts lists.

Class C
Purpose and planning information, technical documentation including record drawings, full operating instructions for each system, detailed maintenance instructions and schedules, parts lists, modification instructions, disposal instructions.

Class D
This classification of manual is similar to Class C, but with method statements, procedures and results of all tests undertaken during the manufacture, installation, site construction and commissioning process. Fully detailed descriptions of systems, sub-systems and equipment components.

Manuals prepared to Class A & B standard are generally considered acceptable for very small, minor projects. For example, the installation of a split air conditioning unit within an existing office building.

For larger more complex installations, it would not be considered acceptable to issue Manuals prepared to Class A or B standard. It is unlikely that Class A & B manuals would contain adequate information to enable the user to safely operate, service and maintain the various systems beyond the defects liability period.

In view of this, and with due regard to the Health & Safety Act (1974)., Manuals for larger projects (beyond the scope described for Class A & B manuals) should, as a minimum, be compiled in accordance with BSRIA Class C requirements.

Class D Manuals are compiled to the same standard as Class C, however, more detailed information will be required in respect of system descriptions (down to component level), procedures and method statements in connection with the installation of services, factory testing & commissioning, site testing and commissioning.
