1.4
Objectives of Quality Assessment System for Completed Road Works.
Quality Assessment System for Completed Road Works was designed and
developed to enable the user to achieve all/any of the following objectives:
1.5
a)
to benchmark the level of quality of the road construction industry
in Malaysia;
b)
to have a standard quality assessment system for workmanship
quality of completed road works;
c)
to assess the workmanship quality of a completed road works
based on the approved standards;
d)
to evaluate the performance of contractors based on the
workmanship quality;
e)
to encourage continual improvements for contractors; and
f)
to compile data for statistical analysis.
Use of Quality Assessment System for Completed Road Works
The Quality Assessment System for Completed Road Works is intended to
complement the best engineering practices, contractual drawings and
specifications in a project. It is not intended to be used independently as
working specifications.
The qualified person shall not use the Quality Assessment System for
Completed Road Works as a design standard and/or to decide if the road or
parts of the road works are in accordance with the relevant Specifications
and by-laws.
It is still the responsibility of the qualified person to ensure that the quality of
the Completed Road Works conform to approved standards, best practices,
specifications and drawings.
Where accessible and practical, all elements identified in this standard shall
be assessed.
5
1.6
Scope of Quality Assessment System for Completed Road Works
The standard sets out the quality of workmanship for the various aspects of
the construction elements for the general road works. The Quality Assessment
System for Completed Road Works covers five main components: Road
Surface, Slope & Retaining Structure, Drainage, Bridge & Other Structures and
Traffic/Road Furniture.
Assessments on the workmanship are carried out based on this standard and
marks are awarded if the workmanship complies with the standards. These
marks are then summed up to give a total score (%) for the road works.
However, the assessment excludes works and tests carried out in pre
construction and during construction works. The road is assessed primarily on
workmanship standard achieved through site inspection and field nondestructive testing.
1.7
Assessment Approach
Assessment of the quality of workmanship is carried out upon completion of
the road project and preferably, before the road is opened to traffic. This is to
ensure that any non-compliance to specific standards is purely based on
quality of construction and not from wear and tear of the completed road.
The assessor shall inspect and assess the identified samples against the
standard and tolerance using the tools specified.
Prior to conducting each assessment, the assessor determines the number of
samples and locations to be assessed. The number of samples and locations
are selected from drawings and plans. The selected samples shall be
distributed as uniformly as possible throughout the project length. All locations
shall be made available for sample determination.
The assessment shall only be limited to this pre-determined sample size and
location and is done on the work that is inspected for the first time.
Rectification and correction carried out after the quality assessment will not
be re-scored. The objective of this practice is to encourage contractors
towards “doing things right the first time and every time”.
The assessment shall be recorded using the site assessment forms as shown in
Annex F to Annex I. An objective ‘yes’ (√) or ‘no’ (x) assessment approach is
adopted to indicate compliance or non compliance of the assessed
component and its respective elements. A ‘-‘ is given to indicate if the
element is not available for assessment. The quality score is computed based
on the number of ‘√’ over the total number of elements assessed.

SECTION 2: QUALITY STANDARD
2.1
Components
The Quality Standards for Completed Road Works are divided into five main
components:1)
Road Surface
The ultimate function of a road is to transport people and goods
from one place to another efficiently with a desirable comfort and
level of safety.
A road can only serve its function and achieve its designed life if
the actual construction is properly done, all the paving materials
are of the required standards and meet the required design
specifications.
Because the road surface is in direct contact with road users, it is
considered the most important component in assessing the quality
of a completed road works. The road surface component is further
divided into three elements namely carriageway, shoulder & verge
and median.
The carriageway is the part of the road where most vehicles are
travelling on. The shoulder & verge is the part of the road which is
adjacent to the carriageway. Vehicle would not normally use this
part of the road as the shoulder act as the emergency lane. Thus
the road shoulder is given less importance than the road
carriageway. The median is the center part which serves as
separator between carriageways.
The elements are assessed in terms of its riding quality, safety and
aesthetics as detailed in Annex A.
2)
Slope & Retaining Structure
The slope & retaining structure component considered in this
standard is only applicable to the structure that is visible after
construction.
The functional performance of the slope & retaining structure
component has an influence on the safety as well as the comfort of
the road user. This component is divided into five (5) main elements:
slope (rigid, soft surface cover, rock), retaining structure, slope
drainage (surface and subsurface), above ground services and
slope furniture.
These elements are assessed in terms of its defect groups such as
crack & damage, joint, fillers and gaps, functionality, finishing and
installations as detailed in Annex B.
7
3)
Drainage
The functional performance of the drainage system of a
completed road works is evaluated to ensure no flooding occurs
which may affect the operations of the road.
For the purpose of this standard, this component is further divided
into four (4) elements: drain (not included under the Slope and
Retaining Structure component), drain cover, sump and pipe/box
culverts.
These elements are assessed in terms of its crack & damage, joints
& gaps, functionality and finishing as detailed in Annex C.
4)
Bridges and Other Structures
The bridge and other structures should be constructed according
to approved standards to ensure structural integrity. Repair and
rectification works should be avoided as this tends to be very costly,
not to mention the inconvenience to the road users.
The bridges and other structures component are grouped into the
different bridge/structure types: above ground structures (such as
road bridges, pedestrian/motorcycle bridges) and special
structures (such as underpass/vehicular box culverts and tunnels).
Each of these bridges/structures is further assessed in terms of its
respective elements as detailed in Annex D.
For special structures such as tunnels, where practical and
accessible, the assessment shall include all visible elements such as
structural, mechanical, electrical, emergency response and fire
protection system. Assessment of these elements shall be by visual
inspection of its physical conditions and system operational.
5)
The Traffic / Road Furniture ideally cover a wide range of physical
fixtures and markings of a road. For the purpose of this standard
and for practicality of implementation, this component has been
streamlined to only cover elements that will have a direct impact to
the traffic operations and flow of a completed road.
The elements covered in this standard are: pavement markings,
traffic calming devices, traffic signs, electrical devices, pedestrian
facilities, kerbs, traffic barriers and delineators.
These elements are assessed in term of crack & damage,
functionality, visibility, finishings and installation as detailed in Annex
E.

Elements
For each of the components identified, the elements to be assessed
are identified accordingly to facilitate practical assessment and
scoring system. The elements and some examples of the type of

SECTION 3: ASSESSMENT
The assessment for the completed road work is carried out through a
statistical and sampling approach.
3.1
Road Weightage
The road weightage for all components are allocated in accordance to
the five road categories. The weightage system is aimed to provide an
objective score corresponding to workmanship quality.
This weightage is developed based on the drivers’ visual perception and
the component’ ability to provide comfort, safety, and assistance (i.e.
control) to the driver. It is deemed that each component will have
different level of relevance for the different road categories, hence the
different weightage as shown in Table 3.1.

Sampling
As it may be impractical to assess the whole length of the road projects, a
sampling approach is recommended. The sample size is developed from
the Statistical formula1 of:
n
=
N
1 + N (e)²
Where,
n =
Sample Size
N =
Total Length of Road in meters / Total Numbers of
Elements
e =
Margin of error, the risk/error the assessor is willing to
accept,
generally this is ± 5%
To determine an economical and practical sample size, a range of e
value was tested as follows:
Low
Option
Medium
High
N (m)
1000
1000
1000
e
10%
6.5%
2.5%
n

19%
62%
From the above range, it is reasonable to adopt a minimum sample size
of 20% or a minimum of one (1) complete sample. The maximum sample
limit shall be determined by the assessor based on economic and
practical considerations.
As a further guideline, the assessor may adopt a minimum or a maximum
sample size as follows:
•
•
•
1
For roads < 1 km in length , the whole section shall be assessed.
For roads where most elements are available, a minimum sample
size of 20% is sufficient
For roads with limited elements, the following practical sample size
is recommended:

Note :
The highest weightage is given to the carriageway element as traffic travels on
the road carriageway. Therefore, it is imperative that the carriageway is of the
highest quality for functionality and safety reasons. The road shoulder acts as the
emergency lane and is given a lower weightage. The lowest is given to the
median which do not carry any traffic.
16
3.3.2
Slope & Retaining Structure
A weightage for the Slope & Retaining Structure component is not applicable
as each of the elements is equally relevant in determining the functionality of
the slope. The Quality Score will be based on the number of compliance over
the total number of elements assessed.
3.3.3
Drainage
The surface and underground drainage are equally relevant in its functionality
and are given equal weightage. However, each drainage elements are
weighted based on its functionality.
For the purpose of the assessment, pipe/box culvert of less than 1.2m in
diameter will only be visually inspected at the inlet and outlet of the culvert.
Whereas pipe/box culvert of 1.2m or bigger in diameter shall be assessed on
all the practical and accessible elements.
The weightage for the drainage elements are shown as per Table 3.3.

3.3.4
Bridge & Other Structure
The two (2) elements of this component (i.e.: bridges and special structures)
are equally weightaged as each is equally important in its functionality.
However, each of the bridge and other structural elements are weighted
based on its functionality.

Assessment Scoring
The quality score of the completed road project is computed based on the
number of compliance over the total number of elements assessed and is
recorded in the Quality scoring form as shown in Annex J.
The total number of compliance and total number of item assessed as
recorded in the site assessment form are summarised in the quality scoring
form. The Quality Score for each component is calculated as follow:
Quality
=
Score
Where,
Σ
Total Compliance
n
Total Assessed
X 100%
n = Component
In the event that each element of a component is weightaged, the Quality
Score is calculated as follow:
Quality
=
Score
Where,
Σ
Total Compliance
n
Total Assessed
X
Allocated Weightage
TOTAL Actual Weightage
X 100%
n = Component
The actual weightage is recalculated to take into account items that are not
applicable for the specific project.
The quality score of each component are further weightage according to the
respective road categories to derive the QLASSIC Score as follow:
