Method-related charges 12 Section 8. This fourth edition supersedes the third edition published in CESMM4 may be used with any conditions of contract for civil engineering work that includes measurement.
The Committee under whose guidance CESMM4 has been prepared will keep the use of the document under review and consider any suggestions for amendment. Revision of the document will be made when such action seems warranted. The Steering Committee was enlarged in by the appointment of an additional representative from each of the Institution of Civil Engineers, the Association of Consulting Engineers and the Federation of Civil Engineering Contractors.
Brierley, BSc Eng , FICE, co-opted Late in , a draft of the revised standard method of measurement was circulated for comment to 71 representative bodies. Trial Bills of Quantities were prepared by 20 organizations.
Discussions with interested bodies continued throughout and and the form of the present document owes much to the suggestions made during this time by bodies outside the committee.
The Steering Committee is indebted to the many people who helped in this way. The object of the work has been to make improvements while retaining the good features of the previous edition of the standard method of measurement. It has therefore been decided to provide for some additional items of measured work and for other items, entered at the option of the tenderer, directly related to methods of construction.
Their use as part of the item numbers in Bills of Quantities is suggested, but is optional. The members of the Review Committee were H. Many organizations contributed comments and suggestions for amendment of the document and others participated by reviewing drafts and giving advice. The Review Committee is indebted to the many people who helped in this way, and particularly to the Federation of Civil Engineering Contractors who appointed a committee to review and comment upon the drafts.
The object of the amendments made in the second edition was twofold. The rearrangement of the former notes is intended to make the document easier to use in two ways.
Firstly, the notes have been re-named rules in order to emphasize that their provisions govern how work should be described and measured in civil engineering bills of quantities and that they have equal status with rules in any other part of the document. The section for measurement of sewer renovation work has been introduced in order to provide for the considerably increased volume of work of this type now being undertaken.
The main changes incorporated in the third edition CESMM3 are amendments to enable its use with the ICE Conditions of Contract, sixth edition January , and the introduction of a standard method of measurement for water main renovation and for simple building works incidental to civil engineering works classes Y and Z.
Account has also been taken of developments in civil engineering technology and the opportunity taken to make minor amendments and corrections to the text of the second edition. There are no changes in principle or in the general arrangement. The Review Committee is indebted to a number of organizations and individuals who have contributed comments and suggestions for amendment. The committee is particularly indebted to E.
Harris: Quantity Surveying whose proposals formed the basis for the new class Z. Beales, Barrister-at-Law J. However by it was being suggested that CESMM required updating to meet current engineering practice and procedure, and a review was initiated by the Institution of Civil Engineers. The review concluded that an update was indeed necessary. Therefore, a decision was taken to remove most references to British Standards. It is therefore necessary for the Bill compiler to identify in the Preamble the relevant clauses within the conditions of contract adopted.
Additionally the terminology and responsibility of individuals varies from contract to contract e. Therefore a schedule has been introduced into the Preamble as a mandatory requirement to ensure that this need for consistency between the contract documents and the Method of Measurement is not overlooked. These are: a. Concrete mixes b. Road construction. It is essential that when billing this type of work compilers do check that these standards are indeed the ones to which they wish to refer to and, if not, complete the schedule in the Preamble and modify the item descriptions accordingly.
It is the intention of the Review Committee that this edition will serve its users as well as the earlier editions have done. The Review Committee received advice and helpful comments from a wide range of organisations and individual practitioners, and would like to express its gratitude to all of them for the assistance they provided.
The members of the Review Committee were J. Beales, Barrister at Law W. Hawkins MSc S. In this document and in Bills of Quantities prepared according to the procedure set forth herein the following words and expressions have the meanings hereby assigned to them, except where the context otherwise requires.
The contract administrator may be the employer, his agent or representative. A hyphen between two dimensions means a range of dimensions which includes all dimensions exceeding that preceding the hyphen but not exceeding that following the hyphen. CESMM4 is intended to be used only for civil engineering works and simple building works incidental to civil engineering works.
CESMM4 provides for simple building works incidental to civil engineering works to be measured in accordance with Class Z. CESMM4 does not deal with the prepara- tion of Bills of Quantities for complex mechanical or electrical engineering work, or com- plex building work or work which is seldom encountered in civil engineering contracts.
The object of CESMM4 is to set forth the procedure according to which the Bill of Quantities shall be prepared and priced and the quantities of work expressed and measured.
Objects of the Bill 2. Consistent with these requirements the layout and content of the Bill of Quantities should be as simple and brief as possible. All work which is expressly required should be covered in the Bill of Quantities. Each class comprises up to three divisions which classifyMode of work at successive levels of detail.
Each division comprises a list of up to eight descrip-description tive features of work. Each item description for precast concrete units shall therefore identify the component of work in terms of the type of unit, its dimensions and mass. Coverage rules 3. A coverage rule does not state all the work covered by an item and does not preclude any of the work stated being covered by a Method-Related Charge.
Additional 3. Description of an item in addition to that required in accordance with paragraphdescription rules 3. Rules printed on a right-hand page above a double line apply to all work in the class. Code numbers may be used to number the items in the Bill of Quantities, the items within the Bill of Quantities being listed in order of ascending code number. Code numbers used as item numbers in the Bill of Quantities shall not form part of the item descriptions or be taken into account in the interpretation of the contract.
Coding of 4. Numbering of 4. Additional description given for an item in accordance with paragraph 3. If three items are required within one part of the Bill of Quantities to allow for precast concrete beams having the same code but different additional description, the items should be numbered H 1 3 6. Appropriate provisions of this section shall also apply to the measurement ofcompleted work completed work. Sections of the Bill 5.
The Bill of Quantities shall be divided into the following sections. List of principal 5. A list of the principal components of the works with their approximate estimatedquantities quantities shall be given solely to assist tenderers in making a rapid assessment of the general scale and character of the proposed works prior to the examination of the remainder of the Bill of Quantities and the other contractual documents on which their tenders will be based.
Preamble 5. The Preamble shall state the methods of measurement other than CESMM4, if any, which have been adopted in the preparation of the Bill of Quantities and are to be used for the measurement of any part of the works. Amendments comprising abbreviation of CESMM4 are usually necessary for contractor-designed work and work which is intended to involve selection between alternatives at the discretion of the contractor.
It is therefore necessary to ensure that there is compatibility between the Method of Measurement and the Conditions of Contract used on the project. A schedule is given below of terms found within CESMM4 where such cross reference is required but, if there are amendments made to CESMM4, then further cross references may be required.
If a term is not referred to in a particular contract e. The schedule shall be replicated in the Preamble to the Bill of Quantities, together with any further required cross references and be completed by the Bill compiler, before the Bill is issued to other parties. The Daywork Schedule, if any, shall comprise either a a list of the various classes of labour, materials and plant for which daywork rates or prices are to be inserted by the tenderer together with a statement of the condi- tions under which the contractor shall be paid for work executed on a daywork basis, or b a statement that the contractor shall be paid for work executed on a daywork basis at rates and prices calculated by adding the percentage additions stated in the standard schedule included in the contract to the rates and prices contained in the aforementioned schedules and by making further adjustments as follows.
Provisional Sums for work executed on a daywork basis may be given comprising separate items for labour, materials, plant and other charges. Where a Daywork Schedule of the form stated in sub-paragraph b of paragraph 5. The price inserted against each such item shall be calculated by applying the percentage addition or deduction inserted by the contractor in the Daywork Schedule to the amount of the associated Provisional Sum. Work items 5.
The items in the Bill of Quantities which are to be priced and to contribute to theDivision of the Bill of Tender Total may be arranged into numbered parts to distinguish between those parts ofQuantities into parts the work of which the nature, location, access, limitation on sequence or timing or any other special characteristic is thought likely to give rise to different methods of construc- tion or considerations of cost.
General items Class A may be grouped as a separate part of the Bill of Quantities. Headings and 5. Each part of the Bill of Quantities shall be given a heading and groups of itemssub-headings within each part be given sub-headings. Headings and sub-headings shall be read as part of the item descriptions to which they apply. A line shall be drawn across the item description column below the last item to which each heading or sub-heading applies. Headings and sub-headings shall be repeated at the start of each new page which lists items to which they apply.
Extent of itemization 5. Descriptions 5.
