Basic record drawings and manufacturers’ literature
Record drawings, manufacturers’ operating instructions,
user manuals, test certificates and parts lists.
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
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
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.
