Measurement rules in the Work Classification set out the conditions under whichwork shall be measured and the method by which the quantities shall be computed ifother than in accordance with paragraph 5.19. M2 The Commencing Surfaceadopted in the preparation ofthe Bill of Quantities shall beadopted for the measurement ofthe completed work. comment to 71 representative bodies. Trial Bills of Quantities were prepared by 20organizations. Discussions with interested bodies continued throughout 1973 and 1974and the form of the present document owes much to the suggestions made during this Description of an item in addition to that required in accordance with paragraph3.1 shall be given where required by any provision of section 5 or by any applicableadditional description rule in the Work Classification. Where additional description isgiven, a separate item shall be given for each component of work exhibiting a differentadditional feature, for example A list of the principal components of the works with their approximate estimatedquantities shall be given solely to assist tenderers in making a rapid assessment of thegeneral scale and character of the proposed works prior to the examination of theremainder of the Bill of Quantities and the other contractual documents on which theirtenders will be based.D2 Invasive plant species shallinclude any plant whose controlis governed by legislation andwhich is treated by herbicidal orchemical process. Coding 4.1. For convenience of reference each item in the Work Classification has beenassigned a code number consisting of a letter and not more than three digits. The lettercorresponds to the class in the Work Classification in which the item occurs and thedigits give the position of the item in the first, second and third divisions of the class, forexample

the work of revision was undertaken by Martin Barnes, PhD, BSc(Eng), MICE,who worked initially under an agreement with the University of Manchester Institute ofScience and Technology and, after he left the University in 1972, under a direct C2 Item descriptions forexcavation shall be deemed toinclude removal of existing pipesof any material or diameter.

Preamble 5.4. The Preamble shall state the methods of measurement other than CESMM4, ifany, which have been adopted in the preparation of the Bill of Quantities and are to beused for the measurement of any part of the works. Such methods of measurement shallcomprise those adopted and to be used for any work not covered by CESMM4 and anyamendments to CESMM4 which have been adopted and are to be used. Amendmentscomprising abbreviation of CESMM4 are usually necessary for contractor-designed workand work which is intended to involve selection between alternatives at the discretion ofthe contractor. The extent of the work affected by all amendments to CESMM4 shall bestated in the Preamble. Excludes: Compaction (included in class E)Grouting carried out from within tunnels, shafts and other subterranean cavities (included in class T)Grouting carried out from within sewers (included in class Y) One item for precast concrete work shall not include more than one of the types ofconcrete unit listed in the first division of Class H, neither shall it include differentunits whose dimensions are not within one of the classifications listed in the seconddivision of Class H, nor shall it include different units whose mass does not lie withinone of the ranges listed in the third division of Class H.

Provisional Sums for work executed on a daywork basis may be given comprisingseparate items for labour, materials, plant and other charges. Where a Daywork Scheduleof the form stated in sub-paragraph (b) of paragraph 5.7 is used each Provisional Sumshall be followed by an item for the adjustment referred to in that sub-paragraph.
