MALAYSIAN STANDARD METHODS

OF MEASUREMENT FOR CIVIL

ENGINEERING WORKS

(CESMM)

(2)

Scope of civil engineering works

Civil engineering is a professional engineering

discipline that deals with the construction and design of public and private sector works such as

bridges, roads, dams and buildings.

General civil engineers work closely with surveyors

and specialized civil engineers to fit and serve fixed projects within their given site, community and terrain by designing grading, drainage,

pavement, water supply, sewer service, electric and communications supply and land (real property) divisions.

(3)

Scope of civil engineering works

(continued)

Construction engineers engage in the design of

structures temporary, cost estimating, planning and

scheduling, materials procurement, selection of

Measurement for Civil Engineering

Works

 The civil works measurement referred to a document called 'Civil

Engineering Standard Method of Measurement '(CESMM).

 Before this document is produced, the party who responsible for the

working measurement refers to the method adopted in the United Kingdom named ‘CESMM 2nd Edition or 3rd Edition’.

 There are a large part of the measurement refer to methods used in

building works or more unfortunate, they use their own

measurement system. This led to inconsistencies in measurement procedures. As a result, contractors have difficulty to appreciate the tender.

 The actual measurement work must take into account the level of

complexity of work undertaken. Work measurement for any one item of work is also closely related to the methodology and

Malaysian Standard Method of Measurement

for Civil Engineering Works

MALAYSIAN STANDARD METHODS OF MEASUREMENT FOR CIVIL

ENGINEERING WORKS is to be used in conjunction with the Conditions Of

Contract for Civil Engineering Works.

 Does not deal with the preparation of BQ

for mechanical & electrical engineering work, building work or work which is seldom encountered in civil engineering contracts.

 If any such work to be included in the

contract, such work shall be measured in accordance with their respective SMM and shall be stated in the Preambles to

Development Of Civil Engineering

Codes Of Measurement

1933 – ICE provide the 1

st

time a standard procedure for drafting BQ for

civil engineering works – no uniformity of practice & engineers

worked up their own systems.

1953 - Revised documents named Standard Method of Measurement of

Civil Engineering Quantities

1963 – reissued with slight amendments

1968 – reissued with metric addendum

1976 – reappraisal of the civil engineering code of measurement by

consultation of the construction industry, relevant bodies &

person produced Civil Engineering Standard Method of

Measurement

(7)

Contract Documentation for Civil

Engineering

1.

Conditions of contract

–a written agreement intended to

be enforceable by law to bind the appointed contractor with the employer based on an agreed conditions.

2.

Contract Drawings

– technical / detailed construction

drawings for measurement / costing by QS / engineers – prepared by architect / engineers.

3.

Specification / Preambles

- A concise description of

materials and workmanship, standard or quality of

workmanship. It must convey the architect and engineer’s requirements.

4.

Bill of Quantities

– prepared by Quantity Surveyor based

on measurement from the construction drawings / building plans This document were itemized all the quantities for each categories of works applied in constructing the buildings. E.g. building works, mechanical, electrical works, civil, structural works, infrastructure works, etc. The contractor will priced /estimate all the works associated in completing the buildings during pre-construction stage.

(8)

Reasons for Bills of Quantities

 All tendering contractors base their prices on the same

information & therefore tenders are strictly comparable (even if an error exists in the Bill)

 Contractors are saved the costly exercise of each having to

take off quantities for themselves.

 Bills provide a fair basis for valuing variations and

adjustments for the final account.

 Bills may provide a convenient basis for valuation of

certificated stage payments during the contract, before the accurate re-measurement figures are available.

 Bills provide an approximate checklist for the contractor to

order materials and other resources.

 Bills can provide data for cost analysis for use in cost

Comparison of Civil Engineering and

Building Methods of Measurement

CESMM SMM

provides a standard format, either in

the form of items components and how they should be measured.

various stages of introducing CESMM

classification or space for description of the work that can be developed.

CESMM measurement method using

the concept of method-related charges to present the cost of construction at the site in more obvious, such

as covering the cost of site

preparation and building machinery operating costs, labor force and so on.

The details of building works are

more in precise stage at the time preparing BQ.

Building work covers more work

sections in consequence subject to more detailed measurement.

(10)

Scope of measurement based on

CESMM

Various civil engineering works including

roads, railway, bridges, artificial channels,

canals and drainage, shipyard, ports, bases,

embankments, structure-breaking waves and

drainage work.

Apart from that it also includes projects such

as structural engineering among others, metal

work, reinforced concrete work, stone work,

wood work and brick work

(11)

Procedures and Practices of

CESMM

Include the scope of most project management such as:

 selection types of contracts,  documentation,

 preparation of drawings,  specifications,

 project information,

 contract terms and list of quantities,

 preparation of list of material requirements / quantities,  Method statement - detailed list of detailed construction

work with short explanation with quantity measured by CESMM

 Explanation on the scope of work that will be implemented

by the contractor and then be the basis for pricing the tender.

(12)

Purpose of CESMM

The main purpose of the measurement

based on CESMM is for

coordinating and

planning of the quantity list, to list the

details of work to ensure consistency

and systematic and to state the new

techniques of construction clearly.

(13)

FUNDAMENTAL PRINCIPLES OF CESMM

CESMM; Section 1

Definitions

A number of definitions are contained.

Referring to words / expression that will be

defined in the CESMM and preparation of bill of

Quantities.

Words and expression defined in the CESMM

shall have the same meaning when defining the

words / expression in the Conditions of Contract

and the Specifications

FUNDAMENTAL PRINCIPLES OF CESMM

CESMM; Section 3

Application of the Work Classification

Work classification divides work into

18

main

classes; Class A- Class R

Each class comprises up to

3 division

which classify

work at successive level of detail.

First division Second division Third division

Each division comprises a list of up to

8 descriptive

features of work.

Each item description shall identify the component

of work covered with respect to one feature from

each division of the relevant class.

(16)

FUNDAMENTAL PRINCIPLES OF CESMM

CESMM; Section 4

Coding & Numbering of Items

 Each item in the work classification has been placed with

the code and numbering system that alphabetically and not more than three digits.

 The letter corresponds to the class in the work

classification in which the items occurs and the digits give the position of the item in the first, second and third

divisions of the class.

 E.g. Code F.3.1.0 identifies an item as

Class F concrete works 1st Division 3 precast concrete

2nd Division 1 beams

3rd Divison 0

FUNDAMENTAL PRINCIPLES OF CESMM

CESMM; Section 4

Coding & Numbering of Items

Reasons:

 It gives an advantage to the tendered contractors due

to bills that have code.

 Quantity surveyor feels that they are assisted by the

code and numbering system and can be used as a brief reference to the file system and data costs.

 Each class work contains a set of measurements,

definitions, coverage, additional rules of measurement that expands and clarify all information and evidence.

 Every classification of work explains every units for each

item of work, within the total allocation and numbering

system for each item, the items in units of meters long, in units of square meters of area (hectares for cleaning

Method-Related Charges

 Meaning: the sum for an item inserted in the BQ by a

tenderer.

 Two types:

Time-related charges – a method-related charge for

work, the cost of which is to be considered as

proportional to the length of time taken to execute the work

Fixed charge- a method-related charge which is not a

time related charge.

 A tenderer may insert in the BQ the method related charges

as he may decide to cover items of works relating to his intended method of executing the works, the cost of which are not to be considered as proportional to the quantities of the other items and for which he has not allowed in the rates and prices for the other items.
