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

Product Information

In 1964, the Council of the Institution of Civil Engineers set up a Committee under theChairmanship of T. A. L. (now Sir Angus) Paton, CMG, BSc(Eng), FICE, to proposerevisions to the Standard Method of Measurement of Civil Engineering Quantities. In M3 A quantity shall be givenagainst all items for specifiedrequirements of which the valueis to be ascertained anddetermined by admeasurement.A unit of measurement shall bestated for each such item.

A11 Item descriptions fordisposal of controlled andhazardous materials shall statethe nature of the material. 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 M2 An item may be given for aParent Company Guaranteewhere it is envisaged a tenderermay be a subsidiary of a largercompany or group.

The opportunity has also been taken to update a number of other areas, and deal with afew known problems that have emerged over the years. 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.
