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:

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. 1.5 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 non-destructive 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) Traffic / Road Furniture 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.

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.

Table 3.1: Road Weightage for All Components

Weightage by Road Categories (%) Components A B C D E

3.2 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:

Option Low Medium High

N (m) 1000 1000 1000

e 10% 6.5% 2.5%

n 9% 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:

• 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: 1 Elementary Sampling Theory, by Yamane 1967

C1 25%

C2 50% 20% 5 km 1

D 25%

E 50% 20% 3 km 0.5

Note: * % of the total number of intersections on the project road. The sample shall be selected based on the road chainage and each sample shall, as much as possible, cover all the 5 components to be assessed. 3.3 Weightage Guideline for Assessment 3.3.1 Road Surface The weightage for Road Surface elements are allocated as per Table 3.2.

Table 3.2: Weightage for Road Surface Elements

Weightage % Road Surface Elements Total Breakdown

1. Carriageway 70

Riding Quality 50 Safety 15 Aesthetic 5

2. Shoulder & Verge 20

3. Median 10

Total 100 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.

Total 100 Note : The highest weightage value is given to the drainage element that is most affected in terms of its functionality to carry off water should quality is compromised. The lowest weightage is allocated to drain cover as its function is for safety purposes

17

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.

3.4 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:

Total Compliance Quality Score = Σn Total Assessed

X 100%

Where, n = Component In the event that each element of a component is weightaged, the Quality Score is calculated as follow:

Total Compliance Allocated Weightage Quality Score = Σn Total Assessed

X TOTAL Actual Weightage

X 100%

Where, 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:

QLASSIC Score = Σn Quality Score X Road
