CESMM4: Civil Engineering Standard of Method and Measurement: Civil Engineering Standard Method of Measurement (CESMM4 Series)

Product Information

M16 Filling of excavationsaround completed structuresshall be measured only to theextent that the volume filled isalso measured as excavation inaccordance with rule M6. M10 The mass measured forreinforcement in diaphragmwalls shall include that ofstiffening, lifting and supportingsteel cast in. particular form of contract, but of course the contract must accommodate ameasure & value approach. It is therefore necessary for the Bill compiler toidentify in the Preamble the relevant clauses within the conditions of contract

Item descriptions 3.1. The Work Classification divides work commonly encountered in civil engineeringcontracts into 26 main classes. Each class comprises up to three divisions which classifywork at successive levels of detail. Each division comprises a list of up to eight descrip-tive features of work. Each item description in the Bill of Quantities shall identify thecomponent of work covered with respect to one feature from each division of therelevant class, for example A18 Item descriptions for triaxialcell and Rowe cell tests shallstate the number of incrementsand the effective pressures. A2 Item descriptions for thenumber and depth of trial pitsand trenches (B 1 1–4 �) shallidentify separately those whichare expressly required to beexcavated by hand. M3 Excavation classed as bydredging in the Bill of Quantitiesshall be measured as bydredging irrespective of themethod of excavation adoptedby the Contractor. Object of CESMM4 2.3. The object of CESMM4 is to set forth the procedure according to which the Billof Quantities shall be prepared and priced and the quantities of work expressed andmeasured.itemization and description(c) to review the subdivision of work into items so that a more sensitive and was published. Secondly it was to take the opportunity of altering the wording of thesmall number of provisions of the first edition which experience had shown were notworking either as smoothly as they might or in the way which had been intended. Thesecond edition of the CESMM is consequently not a radical departure from the first

Additional description rule A1 of Class H requires that the specification of theconcrete in each precast concrete unit shall be stated. Accordingly, this rule also meansthat separate items shall be given for units cast from concrete of differentspecifications. A7 The composition, locationand working load and details ofwater and grout testing,pregrouting and grouting shallbe stated in item descriptionsfor ground anchorages.have, as far as possible, been laid out alongside the parts of the classification tables towhich they relate. A12 Item descriptions for platebearing tests shall state whetherthey are in pits and trenches orboreholes or at the surface.

the Federation of Civil Engineering Contractors who appointed a committee to reviewand comment upon the drafts.A27 Item descriptions for pointload tests shall state the type oftest required and the minimumdimensions of the samples.

A CESMM advisory service has been established since publication of CESMM and willcontinue for CESMM4. However, it is not in a position to advise on derivatives ofCESMM. The challenge of updating references to technical standards had been identified, and isincreased by the use of CESMM in other countries which have their own national Coverage rules 3.8. Coverage rules in the Work Classification provide that the work stated is deemedto be included in the appropriate items to the extent that such work is included in thecontract. A coverage rule does not state all the work covered by an item and does notpreclude any of the work stated being covered by a Method-Related Charge. Item descriptions for work which is divided between two classes require such limitations tobe stated, for example An item for a general contingency (the General Contingency Allowance), ifinstructed by the employer, shall be given in the Grand Summary following the total ofthe amounts brought forward from the Part Summaries.
