BCA Construction Quality Assessment System CONQUAS

-

Quality workmanship is important in today's construction industry. The high quality achieved in building projects ensures future marketability and enhances the confidence of clients.

The QLASSIC is a quality assessment system developed by Construction Industry Development Board (CIDB), Malaysia whereas CONQUAS® is from Building Construction Authority (BCA), Singapore. Both quality assessment systems are widely used in Malaysia to measure quality level achieved on completed building projects.

The Construction Quality Assessment System (CONQUAS â), introduced in Singapore since 1989, serves as a standard assessment system on the quality of building projects. A defacto national yardstick for the industry, CONQUAS â has been periodically fine-tuned to keep pace with changes in technology and quality demands of a more sophisticated population. In 1998, BCA introduced a number of new features to CONQUAS â resulting in the launch of CONQUAS â 21. Such refinements make CONQUAS â scoring more comprehensive and customer oriented. The latest CONQUASâ 8th edition was launched on 31 October 2012 to promote design and materials which support both high quality and productivity.

By using CONQUAS â as a standardized method of quality assessment, developers are able to use the CONQUAS â score to set targets for contractors to achieve and also assess the quality of the finished building.

Construction Industry Standard (CIS 7:2006) on Quality Assessment System for Building Construction Work

--

-

This CIS 7 was developed in November 2006 by CIDB's Technical Committee (TC) that comprises of representatives from Public Works Department (PWD), Jabatan Perumahan Negara (JPN), Real Estate and Housing Developers Association (REHDA), Pertubuhan Akitek Malaysia (PAM), Master Builders Association Malaysia (MBAM), National House Buyers Association (HBA) and other relevant organizations. This standard specifies requirements on quality of workmanship and assessment procedures for building construction work. The requirements in this standard are divided into four main building components:

a) Structural Works

Assessment is carried out throughout the various construction stages. The numbers of samples are determined based on the gross floor area (GFA) of the building, with a minimum and maximum number of samples.

Structural work assessment comprises of the following building elements:

• Reinforced concrete structure (formwork, pre-cast specific requirements, finished concrete, structure quality and NDT).
• Structural steel work.
• Pre-stressed concrete.

b) Architectural works

Assessment is carried out upon project completion with Certificate of Practical Completion (CPC) and prior to handing over. The numbers of samples are determined based on the gross floor area (GFA) of the building, with a minimum and maximum number of samples.

Architectural work deals mainly with the finishes. This is the part where the quality and standards of workmanship are most visible.

Architectural work assessment comprises of the following building elements:

• Ceiling
• Floor
• Internal wall
• External wall
• Roof
• Perimeter drain and apron
• Door and window
• Internal and external fixture

c) Mechanical and Electrical (M & E) works

The numbers of samples are determined based on the gross floor area (GFA) of the building, with a minimum and maximum number of samples.

Assessment is carried out throughout the various construction stages or upon project completion with Certificate of Practical Completion (CPC) and prior to handing over.

M & E work assessment comprises of the following building elements:

• Electrical work
• Air-conditioning and mechanical ventilation work (ACMV)
• Fire protection work
• Sanitary and plumbing work
• Basic M & E fitting.

d) External works

Assessment is carried out upon project completion with Certificate of Practical Completion (CPC) and prior to handing over. The numbers of samples are determined based on 10m length section or per location, with a minimum number of samples.

External work assessment comprises of the following building elements:

• External drain
• Road work and car park
• Link-way or shelter
• Footpath and turfing
• Playground
• Court
• Fence and gate
• Swimming pool
• Electrical substation

CIS 7 also specifies the sampling guideline and the weightage allocated according to component and building category (see Table below).

Table allocation of weightage according to component and building category

The weightage system, which is aimed at making the score quantitative in representing the quality of workmanship of a building. It has taken into consideration the distribution between the cost proportions of the four components in the various buildings and their aesthetic considerations.

Each building category comprise as follows:

1. Category A (Landed Housing)  Detached, Semi-Detached, Terrace and Cluster House.
2. Category B (Stratified Housing) Flat, Apartment, Condominium, Service Apartment and Town House.
3. Category C (Public Building)  Office Building, School and other related facilities/ buildings intended for public use.
4. Category D (Special Public Building)  Hospital and Airport only.

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.

Winner of the 2006 Cleland Award for Literature from Project Management Institute (PMI).

Quality is a much mentioned but little employed component of project success. There are many quality books, tools, and training courses on the market oriented toward the manufacturing domain, yet they provide little information of relevance to project managers who work with intellectual processes more than the action details of production. So where does a project manager go for guidance on integrating the quality demanded in project implementation? Right here!

Project Quality Management by Kenneth Rose offers project managers a specific, succinct, step-by-step project quality management process not found anywhere else. It gives you an immediate hands-on capability to improve project implementation and customer satisfaction in any project domain and will help maintain cost and schedule constraints to ensure a quality project. This user-friendly guide presents tools and techniques that implement the general methods defined in A Guide to the Project Management Body of Knowledge-Third Edition (PMBOK) published by the Project Management Institute (PMI), and augments those methods with more detailed, hands-on procedures that have been proven through actual practice.
