Building works – SMM1 and SMM2 (2000)
Civil engineering works –
CESMM3 (UK)
MCESMM (2003)
Ad-hoc basis
Based on Survey done during meet the industry with 147
respondents:
• 24% use MCESMM,
• 28% use CESMM (UK) 2nd & 3rd Edition and
• 48% use other method of measurement.

SOME ISSUES IN USING SMM : 1
 Piling works
SOME SAY
OTHERS
3m
Pay 10m for supply and
7 m for driving
7m
Pay 7m for supply and
7 m for driving
Who can say exactly what depth
of pile to be driven??
SOME ISSUES IN USING SMM : 2
 Trench excavation
Payment
based on this
width??
Or this
width??
If this width,
what angle to
use??
SOME ISSUES IN USING SMM : 3
Rate of Fill
CESMM (UK)
SMM2 (M)
- excavation in stages
eg. ‘excavate from 0m to 1.5m depth
from 1.5m to 3.0m depth a.s.o
MyCESMM
- let the Contractor choose the appropriate method
of construction
- difficulties encountered and loss of productivity
associated with increasing depth of excavation
to be reflect in the builtup rate
- measured ‘whole’ = max depth
- item description or drawing should indicate the
depth of excavation to facilitate computation of rate
by the contractor (max depth and commencing
surface stated in description) ( as per 5.20)
IMPORTED FILL
Importing fill materials occur, when
CUT (effective) – FILL =
-ve
DIPOSAL OF EXCAVATED EARTH
Disposing of excavated materials occur, when
CUT (effective) – FILL =

SOME ISSUES IN USING SMM : 4
Rate for Natural Hard Materials (not rock)
JKR/SPJ/1988
Specification for Roadworks published by Jabatan Kerja Raya,
Malaysia
“Rock shall mean material found in ledges or masses in
its original position which would normally have to be
loosened either by blasting or pneumatic tools or, if
excavated by hand, by wedges and sledge hammers. “
“ It shall NOT include material which can be loosened
with a track-type tractor with mounted and drawn
ripper of the following description:
PLANTS USED
Tractor Unit:
Equiptment with a minimum weight of 20 tonnes and
nett horse power rating of 200 brake horse power or
more. The tractor unit is to be in good condition and
operated by experienced personnel skilled in the use
of ripping equipment
Ripping Unit:
The ripper to be attached to the tractor shall be the
most efficient parallelogram type recommended by
the tractor or ripper manufacturer. The ripper shall
have single shank in good working condition with
sharpened cutting point.
ROCK CLASSIFICATION
EARTH (Grade V & VI)
Totally weathered
ROCK (Grade III & IV)
Cracks and fissures,
partially weathered
ROCK (Grade I & II)
Fresh, monolithic, no fractures
or cracks
THE PROBLEM
EARTH (Grade V & VI)
SEDIMENTARY– HARD MATERIAL
ROCK (Grade I & II)
Class F – Earthwork ____________________________________________________________________________
THE PROBLEM
On Site:
In between the two extreme material on site
(earth and rock) we have “ HARD MATERIAL”




which is not been clearly defined
not included in the scope of specification
which the Contractor has to excavate but not
priced accordingly
the current practice, it is usually been paid
under normal excavation i.e. excavation in
earth
Resulting in:
Claim by the Contractor due to low productivity for
excavation in natural hard material (get paid for earth
excavation instead of excavation in rock)
Class F – Earthwork ____________________________________________________________________________
MyCESMM SOLUTION
REDEFINE “ROCK”
ROCK or ARTIFICIAL HARD MATERIAL shall be
material that requires the use of either hydraulic
rock breaker, pneumatic tools or explosives.
…..(MyCESMM)
DEFINE “ NATURAL HARD MATERIAL”
NATURAL HARD MATERIAL shall be material other
than ROCK and ARTIFICIAL HARD MATERIAL
that requires ripping and other specialised
equipment. …. (MyCESMM)
“The Contractor gets paid
For what he Did”
Class F – Earthwork __________________________________________________________________________
HARD MATERIAL/ROCK EXCAVATION
shall required one or a combination of the following
methods:





Excavation using track excavator exceeding a mass
of 44 tones and 321 BHP rating
Ripping using a tractor unit of minimum weight of 37
tones and 305 BHP rating and a ripper attached
Excavation using pneumatic tools
Open blasting
Controlled blasting
- Hard Material & Rock will have a common rate -
Class F – Earthwork __________________________________________________________________________
SOME ISSUES IN USING SMM : 5
Conditions of contract

JKR 203A (Rev. 10/83)
• Clause 26(b) – BQ for Building Works based on SMM2
prepared by Institute of Surveyors, Malaysia
 JKR 203A (2007)
• Clause 26.4 – BQ allowed to be based on CESMM 3 by ICE or
any Method
 When disputes arise say concrete works which SMMs
governs?
Wednesday, October 15, 2014
20
SOME ISSUES IN USING SMM: 6
 Too many SMMs, JKR 203A-2007 allows it but is it
practical?
Eg:
– Under 1 Item - Supply, lay, including excavation, valves, thrust
blocks, etc (CESMM3)
– Under 4 Items - Excavation (I), Supply & Lay including joints (2),
Valve (3), Thrust blocks (4) (Own Method)
– Under 7 Items - Excavation (I), Supply (2), Lay (3), Cutting of Pipes
(4), Joints (5), Valve (6), Thrust blocks (7) (Own Method)
