Collecting constructability improvement ideas

Project constructability improvement data collection techniques including voluntary survey, questionnaires, interviews, preconstruction meeting notes, and final project reports are discussed and analyzed in detail. Constructability data collected on a large refinery expansion project solicited with various collection techniques from various project personnel are presented. Considering six major types of constructability improvements, from both quantitative and qualitative points of view, two primary questions are addressed: (1) Which data collection methods are best in soliciting certain types of data; and (2) which source types are the most effective contributors in soliciting certain types of data? Numerous recommendations for effectively collecting constructability improvement data are presented.
