Presentation Overview
The quality and completeness of engineering design
deliverables have a significant impact on overall project
performance. Thus, project stakeholders should pay close
attention to such issues, with a particular focus on problematic
engineering design deliverables.
This presentation summarizes the findings of the Construction
Industry Institute (CII) Research Team (RT) 320, Definition and
Measurement of Engineering/Design Deliverable Quality,
including the 11 most problematic deliverables and their
significant defects, causal factors, leading/lagging metrics, and
two implementation tools.

1) At least one constructability review meeting is conducted in early FEED/ Design Development or
before?
2) The second constructability review meeting is conducted at or before the end of FEED/ Design
Development?
3) The third constructability review meeting is conducted at or before the 60% design complete?
4) Were the constructability reviews conducted too late to incorporate comments into the design?

AVEVA World Conference NA - Jeyoung Woo, University of Texas at Austin

  • 1. © 2017 AVEVA Solutions Limited and its subsidiaries. All rights reserved. Presentation Overview The quality and completeness of engineering design deliverables have a significant impact on overall project performance. Thus, project stakeholders should pay close attention to such issues, with a particular focus on problematic engineering design deliverables. This presentation summarizes the findings of the Construction Industry Institute (CII) Research Team (RT) 320, Definition and Measurement of Engineering/Design Deliverable Quality, including the 11 most problematic deliverables and their significant defects, causal factors, leading/lagging metrics, and two implementation tools.
