Construction Industry Standard (CIS 19:2011) on Quality Assessment System for Completed Road Works

-

1. Introduction

Quality Assessment System for Completed Road Works is an independent method to assess and evaluate the quality of workmanship of newly completed road works based Construction Industry Standard (CIS 19:2011).

2. 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.

3. 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

4. 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 noncompliance 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 K. 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.
