The includes and excludes list is given at the head of each class. It tells the user of CESMM3 which general types of work are included in a class and which classes cover other similar work which is excluded from that class. In some cases, e. These lists should not be regarded merely as an index to CESMM3; they are important to the interpretation of the coverege of the bill items generated by the classes. Clearly the lists do not set out to be comprehensive; they do not mention everything which is included or everything which is excluded. The classification table is the tabulation of the work components covered by a class, divided into the three divisions es described in section 3.

In some cases, e. These lists should not be regarded merely as an index to CESMM3; they are important to the interpretation of the coverage of the bill items generated by the classes. Clearly the lists do not set out to be comprehensive; they do not mention everything which is included or everything which is excluded.
The horizontal lines in the tabulation indicate which lists of features from one division apply to which features in the other divisions. This is usually straightforward, but must be given close attention where the lines are at different levels in the different divisions.
They should be included in item descriptions in all cases where they would not duplicate information. In one sense they are more important as sometimes they overrule the classification table. The rules are arranged alongside the sections of the classification to which they apply. This is indicated by the horizontal lines which align from the left-to the right-hand pages. Rules printed above a double line apply to all items in a class see paragraph 3.
This style of printing is adopted as an aid to cross-reference between the tables and the rules; it has no effect on interpretation of the rules. They are adopted to comply with British Standards or to keep up with the move co standardize units and terms under the general umbrella of metrication. Thus pipes havea bore not a diameter, because the bore is the diameter of the hole down the middle, and cannot be confused with the outside diameter of the pipe.
Mass is the measure of the quantity of matter; weight is no longer used. Example bill pages are given in this book for each class in the Work Chasification. The examples are not taken from actual contracts. The example bill items, not being related toa particular job, show less non-standard description amplifying the basic descriptions than is given in real bills.
Similarly, in order not to imply that particular specification details are recommended, item descriptions in the example bills frequently refer to hypothetical specification clauses by a clause number or to details on hypothetical drawings.
This procedure is permitted in real bills by paragraph 5. It is adopted at the discretion of the bill compiler in accordance with paragraph 4. They give hypothetical items which demonstrate those applications of the rules in CESMM3 which are novel or would benefit from demonstration for other reasons.
The items are laid out as ifthey were pages from a bill to demonstrate layout, numbering and the use of headings. The examples illustrate the alternative procedures open to bill compilers where CESMM3 permits alternatives. Compilers of real bills should try to be consistent, notto demonstrate all the possible alternatives as the examples do.
Each heading and item description in the example bill pages ends with a full stop. This is a helpful discipline when there are two or more headings at the top of one bill page.
The full stops help to relate the headings to the lines drawn across the description column which show which items apply to each heading see paragraph 5. Within itern descriptions, a semicolon has been used to separate basic from additional description.
