A1 The diameters of holes shallbe stated in item descriptionsfor drilling and driving for groutholes and grout holes. 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

if not, complete the schedule in the Preamble and modify the item descriptionsaccordingly. It is simply not possible to republish CESMM every time that astandard is updated. 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 The Review Committee received advice and helpful comments from a wide range oforganisations and individual practitioners, and would like to express its gratitude to allof them for the assistance they provided. The unit of measurement for each item shall be that stated for the item in theWork Classification. The unit of measurement stated against a descriptive feature inthe Work Classification shall apply to all items to which that descriptive featureapplies. A18 Item descriptions for triaxialcell and Rowe cell tests shallstate the number of incrementsand the effective pressures.M12 The volume of disposal ofexcavated material measuredshall be the difference betweenthe total net volume ofexcavation and the net volumeof excavated material used forfilling.

Sneden, FRICS, FIQS, Federation of Civil Engineering Contractors system should enable much of the repetitive clerical work associated with the use of Billsof Quantities to be simplified, and make the use of computers easier. M16 Filling of excavationsaround completed structuresshall be measured only to theextent that the volume filled isalso measured as excavation inaccordance with rule M6. A14 Where the rate ofdeposition of filling material islimited the limitation shall bestated in item descriptions forfilling.

d ) to take account of new techniques in civil engineering construction andmanagement, their influence on the work itself and on the administration ofcontracts. Additional description rule A2 of Class I requires that the nominal bores of pipes shallbe stated in item descriptions. The range of nominal bore taken from the seconddivision of the classification of Class I shall not also be stated. itemization and description(c) to review the subdivision of work into items so that a more sensitive andM11 Preparation of excavatedsurfaces shall be measured tosurfaces which are to receivePermanent Works whetherpreparation is expressly requiredor not except surfaces which areto receive filling or landscapingand surfaces for whichformwork is measured.

Provisional Sums 5.18. Provision for contingencies shall be made by giving Provisional Sums in the Billof Quantities and not by increasing the quantities beyond those of the work expected tobe required. Provisional Sums for Defined Work shall be included where work is knownto be required but the scope of the work cannot be completely designed but the scopecan be defined. A Provisional Sum for a general contingency allowance shall be given inthe Grand Summary in accordance with paragraph 5.26. A6 Item descriptions for thenumber of rotary drilledboreholes shall state thosewhich are continuations of lightcable percussion boreholes. M9 The volume measured forexcavation within borrow pitsshall be the net volumemeasured for filling. A13 Item descriptions for staticcone sounding tests shall statethe maximum depth of the coneand, where electric cones areused, the maximum capacity ofthe machine.Daywork’ means the method of valuing work on the basis of time spent by theoperatives, the materials used and the plant employed. Adjustment Item 6.3. A tenderer may insert a lump sum addition or deduction against the AdjustmentItem given in the Grand Summary in adjustment of the total of the priced Bill ofQuantities. 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. Theprice inserted against each such item shall be calculated by applying the percentageaddition or deduction inserted by the contractor in the Daywork Schedule to theamount of the associated Provisional Sum. lump sum or target cost, contractors use CESMM for tendering purposes, and in somecases let sub-contracts on the basis of re-measurement, not withstanding that the maincontract is not on a remeasurement basis. A7 The composition, locationand working load and details ofwater and grout testing,pregrouting and grouting shallbe stated in item descriptionsfor ground anchorages.
