D2 Invasive plant species shallinclude any plant whose controlis governed by legislation andwhich is treated by herbicidal orchemical process.

The Commencing Surface shall be identified in the description of each item forwork involving excavation, boring or driving for which the Commencing Surface is notthe Original Surface. The Excavated Surface shall be identified in the description of eachitem for work involving excavation for which the Excavated Surface is not the FinalSurface. The depths of excavation stated in accordance with the Work Classificationshall be measured from the Commencing Surface to the Excavated Surface. M5 Items for Method-RelatedCharges, if any, shall be insertedby the tenderer in accordancewith section 7. there is a variety of contracts for civil engineering including NEC and the InfrastructureConditions of Contract (formerly known as the ICE Conditions of Contract).Additionally some Clients have adopted standard forms produced by other engineeringinstitutions, and large projects are sometimes let on bespoke contracts drawn up by from each of the Institution of Civil Engineers, the Association of Consulting Engineersand the Federation of Civil Engineering Contractors. The members of the committee(�indicates member appointed in 1971) were

agreement with the Institution of Civil Engineers. A Steering Committee was appointedby the Council of the Institution of Civil Engineers to supervise the work. The SteeringCommittee was enlarged in 1972 by the appointment of an additional representative

to enable its use with the ICE Conditions of Contract, sixth edition (January 1991), andthe introduction of a standard method of measurement for water main renovation andfor simple building works incidental to civil engineering works (classes Y and Z). b) ‘Time-Related Charge’ means a Method-Related Charge for work the cost of whichis to be considered as proportional to the length of time taken to execute the work. 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.

A22 Item descriptions forCalifornia bearing ratio testsshall state the compactive effort,surcharge and whether soakingis required. 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 Whilst every care has been taken in the preparation of this document, neither the Institution of CivilEngineers nor the Civil Engineering Contractors Association nor any of their committees can acceptany liability for any loss or damage which may be suffered by any person or organisation as a result ofits use. C3 Items for invasive plant speciesshall include for the disposal ofany vegetable matter remainingafter treatment. Excludes: In situ concrete for:capping of boreholes (included in class B)diaphragm walls (included in class C)excavation ancillaries (included in class E)granolithic and other applied finishes (included in class G)drainage and pipework (included in classes K and L)piles (included in cla

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.

TheExcavated Surface shall beidentified in the description ofeach item for work involvingexcavation for which theExcavated Surface is not theFinal Surface.
