Product Information

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. Any detail of description required to be given in accordance with the WorkClassification may be omitted from an item description provided that a reference is givenin its place which identifies precisely where the omitted information may be found on adrawing or in the Specification. deal with specific problems that had emerged; and updating references to BritishStandards contained in the Work Classification. 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. In 1983, the Council of the Institution of Civil Engineers instructed the CESMMReview Committee to prepare a second edition of the Civil Engineering Standard Methodof Measurement. The members of the Review Committee were A13 Where differentcompaction requirements arespecified for the same fillingmaterial they shall be stated initem descriptions for filling.

The work of analysing the comments and suggestions anddrafting CESMM3 was undertaken by Coopers & Lybrand Deloitte.

The insertion by the contractor of an item for a Method-Related Charge in the Billof Quantities when tendering shall not bind him to adopt the method stated in the itemdescription in executing the Works.

The title of this document is the Civil Engineering Standard Method of Measure-ment, fourth edition, which is abbreviated to CESMM4. CESMM4 is intended to beused only for civil engineering works and simple building works incidental to civilengineering works.
