Quality remains one of the most important parameters in construction, alongside time and cost. However, quality is subjective and it is difficult to quantify.
CIDB, with working groups consisting of public and private stakeholders, in 2005, have put together a construction industry standard or CIS on the base quality requirement for the industry.
The outcome is called Quality Assessment System for Building Construction Works or QLASSIC (CIS 7:2006). The standard has been improved and enhanced according to the construction climate today (CIS 7:2014).
What is Qlassic
Quality Assessment System in Construction (QLASSIC) is a system or method to measure and evaluate the workmanship quality of a building construction work based on Construction Industry Standard (CIS 7:2006). QLASSIC enables the quality of workmanship between construction projects to be objectively compared through a scoring system.
- 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
QLASSIC sets out the standard on quality of workmanship for various construction elements of building construction work. The quality of workmanship of a construction work is assessed according to the requirement of the standard i.e., Construction Industry Standard (CIS 7:2006). Marks are awarded if the workmanship complies with the standard. These marks are then summed up to calculate the QLASSIC Score (%) for a the building construction project.
QLASSIC assessments are carried out through site inspection and use the principles of first time inspection. Construction works that are rectified after an assessment will not be re-assessed. The objective of this principle is to encourage the contractor to "Do Things Right the First Time and Every Time".
