1:100 Plan at level 1—Loose equipment 2—

This coding seems to cover a multitude of omissions in practice. Mirrors, notice boards, fire exit signs, fire extinguishers—all tend to get added latein the life of a project. Rather than re-issuing cluttered-up and dog-eared amended copies of other plans, it is preferable to reserve an (8-) set of copy negatives for eventual use.

External wall details


Assembly details illustrating the entire range of different external wall conditions to be found on the project, including door and window heads and cills, and, in this instance, the footings and ground floor junctions. It would have been equally possible to code these latter conditions A (16)—Foundations, or A (23)—Floors, but these were only two variants on this particular project and common sense prompted their inclusion in the A (21) series rather than a pointless further extension of the elementalisation.

Eaves details Parapet detail

Parapet and eaves details, however, are covered separately under an A (27)—Roof series, largely because the office possessed a standard parapet assembly drawing which it wished to use on this project, and which was already coded as A (27). It is numbered 501 because it is desirable to keep the sequence of standard drawing numbers well clear of numbers used for specific project purposes. The gaps in numbers which thus appear may be criticised as leading to confusion and doubts on site as to whether they are in possession of the complete set. It is felt, however, that the advantages outweigh these possible objections, and that the objections themselves largely disappear if the drawing register procedures discussed elsewhere are adopted.

External wall opening assemblies— Sheet 1

External wall opening assemblies— Sheet 2

The A (21) series will have covered a number of assemblies which also convey information about secondary elements —eg a lot of the head and cill conditions for windows and external doors. The process of filling in external openings schedules in the format recommended previously will automatically throw up a number of conditions not taken care of in this series and these, together with the jamb conditions, form the subject of the A (31) assemblies.

Internal wall opening assemblies— Sheet 1

Internal wall opening assemblies— Sheet 2

A similar series covering internal openings.

Two A1 sheets have been assumed, but the details might equally well have been carried out on a larger number of A4 or A3 sheets. Note that this series conveys assembly information only about the openings themselves—head, jambs and cills where appropriate. Information about what goes in the openings—eg internal door-sets—is given elsewhere in a series of C (32) component drawings. Here again, the necessity for a particular detail will be made apparent by the openings schedule.

Suspended ceiling assemblies

Manufacturers' drawings will often be sufficient for describing the fixing of suspended ceilings. In the present case the drawing covered the timber framework for bulkheads at changes in the ceiling level.

Roofiight assemblies

With the limited elementalisation applied to this set, it may be argued that this drawing could have been grouped under (27)—Roofs, a category which already exists for other purposes.
