A Comprehensive Overview of the Quality Assessment System for Building Construction Works (QLASSIC)

post

Introduction

The Construction Industry Standard (CIS 7), colloquially known as QLASSIC, represents a paradigm shift in the construction industry's approach to quality assurance. Rooted in the principles of continuous improvement and best practices, QLASSIC is a testament to Malaysia's commitment to elevating its construction standards to global benchmarks.


Strategic Objectives of QLASSIC

The system's inception was driven by several strategic imperatives:

1. Standardized Assessment: To harmonize the disparate quality assessment methodologies across the industry, ensuring a consistent and objective evaluation mechanism.

2. Quality Benchmarking: To provide a tangible metric for assessing workmanship quality, facilitating comparisons across projects and contractors.

3. Performance Metrics: To introduce a performance-driven culture among contractors, using quality scores as a key performance indicator (KPI).

4. Industry Competitiveness: To position the Malaysian construction industry at par with international standards, enhancing its competitiveness on the global stage.

5. Data-Driven Insights: To leverage the power of data analytics, using the amassed assessment data for predictive analysis, trend identification, and strategic decision-making.


Scope and Granularity of QLASSIC

QLASSIC's assessment framework is both comprehensive and granular:

1. Architectural Works: This encompasses a detailed evaluation of internal finishes, which includes parameters like surface evenness, alignment accuracy, joint integrity, and material consistency. External finishes are scrutinized for weather resistance, aesthetic consistency, and structural integrity. Material & functional tests further ensure that the used materials adhere to the specified standards and perform optimally under stress tests.

2. Basic M&E Fittings: Mechanical and Electrical (M&E) works form the backbone of any modern construction. The assessment focuses on the functionality, safety, and integration of these systems, ensuring they align with the building's architectural and structural elements.

3. External Works: Beyond the building itself, the surrounding infrastructure plays a pivotal role in determining the project's overall quality. This includes the robustness of drainage systems, the durability of roads and footpaths, and the quality of auxiliary structures like fences and playgrounds.


Technical Standards and Norms

The technical standards underpinning QLASSIC are exhaustive:

1. Architectural Works: Adherence to standards like MS ISO 9001 and MS ISO 10006 ensures that architectural elements meet international quality benchmarks. Specific criteria, such as deflection limits, moisture resistance, and acoustic insulation, are meticulously evaluated.

2. Basic M&E Fittings: Compliance with standards like MS IEC 60364 and MS 1936 ensures that M&E installations are safe, energy-efficient, and sustainable. Parameters like load capacity, redundancy, and fail-safe mechanisms are critically assessed.

3. External Works: Adherence to standards like MS 1217 and MS 1228 ensures that external works are sustainable, environmentally friendly, and resilient to external stressors.


Assessment Methodology

The QLASSIC assessment methodology is rooted in statistical rigor:

1. Sampling Strategy: Adopting a stratified random sampling approach ensures that the assessment is representative of the entire project, eliminating biases and ensuring objectivity.

2. Scoring Mechanism: A weighted scoring mechanism, based on the criticality and visibility of each element, ensures that scores accurately reflect the project's overall quality. The use of control charts and statistical process control techniques further enhances the assessment's accuracy.


Weightage System

The weightage system is tailored to the specific nuances of different building categories:

Residential vs. Non-Residential: Recognizing the distinct challenges and requirements of residential and non-residential constructions, the weightages are meticulously calibrated to reflect these differences.


Assessor Competencies

Assessors are the linchpins of the QLASSIC system:

1. Training: Rigorous training programs, benchmarked against international best practices, ensure that assessors are equipped with the latest knowledge and techniques.

2. Certification: A stringent certification process, involving both theoretical and practical evaluations, ensures that only the most competent professionals are entrusted with assessment responsibilities.

3. Continuous Learning: Regular refresher courses and knowledge-sharing sessions ensure that assessors stay abreast of the latest industry developments.


Architectural Works Assessment

This segment represents the crux of the QLASSIC assessment:

1. Technical Parameters: Parameters like tensile strength, compressive strength, thermal conductivity, and fire resistance are evaluated using state-of-the-art instruments and methodologies.

2. Aesthetic Considerations: Elements like color consistency, surface finish, and alignment are assessed using both objective metrics and subjective evaluations.


Conclusion

The QLASSIC system represents a quantum leap in the construction industry's approach to quality assurance. By marrying technical rigor with strategic vision, it ensures that Malaysian constructions stand tall on the global stage, both in terms of quality and sustainability.
