Calculating Overall Quality
Since a construction project comprises various resources such as materials, machines, method, labors, and even management, the overall quality of a construction project is calculated by each activity's quality
and its quality weight
:
where the general quality of a construction project
number of activities in a construction project;
quality weight indicator of each construction activity
, and
quality performance of construction activity (i) calculated by its labor quality, material quality, construction equipment quality, and administration
,
, EWT
weight indicators of construction labor, material, equipment, and administration in activity
respectfully;
quality of construction labor, material, equipment, and administration in activity
