Phase IIa: Factors Analysis
Data collection from 53 participants from Graham, Ellis-Don, PCL, and Ledcor. The participants recognize important factors that affect construction productivity.
Phase IIb: Clusters Analysis
Identified factors are further combined into clusters based on the discussion between the research participants and the research team. These clusters are more logical for the industry to understand reasons for productivity performances.
