INTRODUCTION3. Method adopted in preparation of CESMM a) Study existing procedures and practices by JKR, JPS, LLM,

consultant firms, and etc.b) Discussion and workshop with various organization

including contractors, specialist and other industry players.

c) Compilation of most common standard practices in preparation and measurement of Bills of Quantities.

d) Provision of latest trends adopted by JKR, including traffic management and control and environmental enhancement

e) CESMM3 UK is used as a guide in preparing this CESMM.

The CESMM has been prepared with the following concept:‐a) User friendly and familiarity with local contextb) Flexible to suit various types of civil engineering worksc) Relevant and acceptable to the industry practice

INTRODUCTION

4. Advantages of CESMM:‐a) With one standard method of measurement to be

referred ‐ the industry will be having “one language” while improving the communication within the parties involved

b) Cost be better managed as it provides compilation of data and be used as cost control tool

c) Less dispute since the scope of works and measurement method are clearly defined

d) Computerization can be done with standard phraseology and coding

e) Better suit to local condition and method of working on site, provides measurement convention

GENERAL APPLICATION OF CESMM

CESMM is divided into 8 Sections as follows:‐• Section 1‐ Definitions• Section 2‐ General Principles• Section 3‐ Application of the Work

Classification• Section 4‐ Coding and Numbering of Items• Section 5‐ Preparation of Bill of Quantities• Section 6‐ Completion, Pricing and use of

Bill of Quantities• Section 7‐Method‐Relates Charges• Section 8‐Work Classifications


Section 8 is further divided into 18 classes as follow:‐Class A ‐ General ItemsClass B ‐ Soil Investigation WorksClass C ‐ Slope Stabilization and Ground TreatmentClass D ‐ Demolition and Site ClearanceClass E ‐ EarthworksClass F ‐ Concrete WorksClass G ‐ Road worksClass H ‐ Drainage WorksClass I ‐ PipeworksClass J ‐ Piling Works


Class K – Brickworks, Blockwork and MasonryClass L – TimberworksClass M – MetalworksClass N – Painting WorksClass O – Rail TracksClass P – Environmental Protection and EnhancementClass Q – Traffic Management and ControlClass R – Miscellaneous Works

DEFINITIONS (SECTION 1)

Some of the key words are defined in this section, for example:‐a) ‘Conditions of Contract’ means the conditions of

contract used for civil engineering works.b) The word ‘Work’ includes to be carried out,

goods, materials and services to be supplied and liabilities, obligations and risks to be undertaken by the Contractor under the Contract

c) The term ‘expressly required’ means shown on the drawings, described in the specifications or instructed by the Engineer/Superintending Officer (SO)/ Project Director (PD) pursuant to the Contract.

GENERAL PRINCIPLES (SECTION 2)

Some of the salient points under thissection are as follows:‐a) EXCLUSION: CESMM does not deal with the

preparation for mechanical and electrical work, building work or work which is seldom encountered in civil engineering contract. Where such work is to be included in a contract for civil engineering work, they shall be measured in accordance with their respective standard method of measurement.

b) The objective of the CESMM is to set forth the procedure for the measurement of the work according to which the Bill of Quantities shall be prepared and priced.

GENERAL PRINCIPLES (SECTION 2)

The objectives of the Bill of Quantities are:‐

(a) To provide such information of the quantities of work as to enable tenders to be prepared, analysed & managed efficiently and accurately;

(b) When a contract has been entered into, to provide standardisation for the use of the priced BQ in the valuation of work executed and

(c) When a contract has been entered into, to provide for a basis in valuing variations, in accordance to provisions of the Conditions of Contract

In order to attain these objectives, Work should be itemized in the Bill of Quantities in sufficient detail for it to be possible to distinguish between the different classes of work, location etc which may give rise to different consideration of cost.

APPLICATON OF THE WORK CLASSIFICATION

(SECTION 3)

This section deals with the item description in the Bill ofQuantities, mode of description, units of measurement,Measurement rules, definitions rules, coverage rules and additional description rules.

a) The Work Classification divides work commonly encountered into 18 main classes (Class A to class R). Each class comprises up to three divisions which classify work at successive levels of detail (First division, second division and third division). Each division comprises of a list of 8 descriptive features of work. Each item description in Bill of Quantities shall identify the component of work covered with respect to one feature from each division of the relevant class.


(SECTION 3)

b) Item description for Works shall generally identify the component of the Works and not the tasks to be carried out by the Contractor, for example: an item should be described as ‘Mild steel bar reinforcement, 6mm diameter’ not as ‘Supply, deliver, cut, bend and fix mild steel bar to 6mm diameter’.

c) Measurement rules in the Work Classification set out the conditions under which the work shall be measured and the method by which the quantities shall be computed.

d) Definition rules in the Work Classification define the extent and limits of the class of work represented by a word or expression used in the Work Classification and in the Bill of Quantities.


(SECTION 3)

e) Coverage rules in the Work Classification provide that the work stated is deemed to be included in the appropriate items.

f) Where additional description is given under additional description rules in the Work Classification a separate item shall be given for each component of the work.

g) Rules printed on the right hand page above a double line apply to all work in the class. Other rules on the right hand page apply to a particular groups of items as shown by the classification table.

CODING AND NUMBERING ITEMS (SECTION 4)

a) Coding – For convenient of reference and computerization each item in the Work Classification has been assigned code number consisting of a letter and not more than 3 digits.

E.g.: Code E 1 1 1 identifies as; Class E Earthworkfirst division 1 Excavationsecond division 1 Strippingthird division 1 Topsoil

b) Item Numbers – 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

c) Coding of unclassified items – Where a feature of an item is not listed in the Work Classification the digit 9 shall be used in appropriate positions in the code number. Where there is an item to which a division of classification does not apply for which fewer than 3division the digit 0 shall be used in appropriate positions in the code number

CODING AND NUMBERING ITEMS (SECTION 4)

d) Numbering of items with additional description – where code numbers are used as items numbers a suffix number may be used to distinguish items which has the same code number but different additional description.

e.g. : E 1 1 1.1 for earthwork item where stripping of topsoil required to state whether reuse or disposal.

PREPARATION OF BILL OF QUANTITIES (SECTION 5)

This section deals, mainly in the preparation of the bill of quantity, preambles, daywork schedule, description of work item, Prime Cost items, Provisional Sum, Quantities, Unit of Measurement.

Any amendment to the CESMM shall also be stated. Wherever amendments are made the amendments shall take precedence over the CESMM.

b) All item shall be described in accordance with the Work Classification but further itemization and additional description may be provided if the nature, location or any special characteristic of work is thought likely to give rise tospecial method construction or cost consideration.

PREPARATION OF BILL OF QUANTITIES (SECTION 5)

c) The estimated price of Work to be carried out by Nominated subcontractor shall be given in the bill of quantities as a Prime Cost Item. Each Prime Cost Item shall be followed by;

i. Item for attendance in connection therewith, ii. Item expressed as a percentage of the price of the Prime Cost Item in respect of all other charges and profit.

d) Provisional Sum for specific contingencies shall be given in theWork Classification of the Bill of Quantities.

e) Quantities in the Bill of Quantities shall be computed nett using dimension from the drawing unless otherwise directed by a measurement rule in CESMM or by the contract and no allowance shall be made for the bulking, shrinkage or wastage.

b) Each part of the Bill of Quantities shall be totalled and the totals carried to the Grand Summary

METHOD‐ RELATED CHARGES (SECTION 7)

Method‐Related Charges

a) Definition – ‘Method‐Related Charge’ means the sum of an item inserted in the Bill of Quantities by a tenderer to cover items of Work a relating to his method of construction, the cost of which are not proportional to the quantities and he has not allowed for in the rates and prices for other items.

b) Each item for a Method‐Related Charge inserted in the Bill of Quantities shall be fully described so as to define precisely the extent of the Work covered and to identify the resources to be used.

METHOD‐ RELATED CHARGES (SECTION 7)

c) Payment when method not adoptedIn the event of satisfactory execution of any part of the Works which has been the subject of an item for a method‐related charge using a method other than that described in the Bill of Quantities the contractor shall nevertheless be entitled to the payment of the method‐related charge.

The amount of a method‐related charge shall be neither increased or decreased by reason only of any change in the method made by the contractor, unless such change has been instructed by the Engineer/SO/PD. Then in which case the appropriate variation clauses of the Condition of Contract apply.
