Proactive Approach to Engineering and Design Deliverables Quality Enhancement

Abstract

This paper presents research findings by the Construction Industry Institute (CII) Research Team (RT) 320, Definition and Measurement of Engineering/Design Deliverable Quality, to manage the engineering and design deliverable defects of the engineering deliverables. The team identified the 11 most engineering and design quality problematic deliverables and 73 significant defects associated with the 11 problematic deliverables by conducting a survey of construction industry professionals. They analyzed 73 significant engineering deliverable defects to determine the impacts, causal factors, and frequency of these defects. The team generated 118 leading metrics associated with causal factors and 23 lagging metrics associated with both deliverable defects and their impacts. Lastly, the team developed an implementation tool, the design deliverable quality assessment (DDQA) tool, to assess the quality of the 11 problematic deliverables and to identify potential defects with current status quo. This paper’s primary contributions are the identification of the problematic engineering and design deliverables and their significant defects, and analysis of these defects to eliminate engineering and design deliverable defects.
