When asked about Integrated Project Delivery (IPD) or Integrated Design (ID), many in the building design industry respond, "We've always done it." But, when asked to explain the process, they reply in a myriad of ways. The range of answers is no surprise, given that leading industry associations have each produced a handbook, guide or standard about the IPD or ID process. Some projects may not implement basic IPD/ID methods, leaving it to project leaders to customize the best approach. And, it's obvious that not all projects or design teams are the same, so which process is appropriate? The first IPD/ID best practice is to identify a specific IPD/ID process to follow, one that captures the critical benefits of any given IPD/ ID model and deals with the ancillary pieces accordingly.This paper identifies evolving methods, guidelines, and tools that define how project teams can reengineer the design process at a more holistic and effective level. It presents the similarities and differences between methods so that owners and design teams can identify the best approach for their project, and offers insight into the differences between the two terms. It also highlights an example of how one of the most well-defined ID standards was used for the United States Department of Labor's (DOL) Sierra Nevada Job Corps Center Cafeteria project near Reno, NV. Additionally, this paper will help owners, designers, and contractors better understand the ID methods available and how to use them to create an effective design team.
