QLASSIC Score ?

Score Calculation Formula

Elements Score (%)
= (total no. of compliance ÷ total no. of check)

X weightage of each element

116655

166

QLASSIC Score

Formula 1:

Architectural Works Elements Score (%)
= (no. of compliance ÷ no. of check) X weightage of every element

Formula 2:
Architectural Works Component Score (%)
= total score for all architectural works elements X weightage

Formula 3:
External Works or Basic M&E Fittings Component Score (%)
=(no. of compliance ÷ no. of check) X weightage of every component

Formula 4:

Total Score or QLASSIC Score (%) = total score for all components
