Quality Assessment System in Construction (QLASSIC) is a system or method to measure and evaluate the quality of workmanship of a construction work based on the relevant approved standard. QLASSIC enables the quality of workmanship between construction projects to be objectively compared through a scoring system.

Objective of QLASSIC
  • To benchmark the quality of workmanship of the construction industry.
  • To establish a standard quality assessment system on quality of workmanship of construction work.
  • To assess the quality of workmanship of a construction project based on the relevant approved standard.
  • To be used as a criterion to evaluate the performance of contractors based on quality of workmanship.
  • To compile data for statistical analysis.
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).

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.
