The Benefits of Reinventing the Wheel - IPD

For the Seattle Children’s Bellevue Clinic (SCBC), the team used Integrated Project Delivery (IPD), Continuous Project Improvement, LEAN, and the Owner's healthcare delivery improvements to "shave three months, 30,000 sf, and $20 million off the initial project estimates," according to this successful AIA award nomination by NBBJ.  SCBC was a laboratory for the best team practices, resulting in a "true efficiency revolution." 

 

Cornerstones of the IPD process included jointly-defined project goals, shared risk/reward, early team participation, and asking each partner to participate outside their own scope (or "silo").  "The result was the creation of a culture of trust, respect, and collaboration that maximized the client’s budget and reduced construction time.”  Cross-pollination of ideas resulted in better design solutions than individual disciplines working separately, such as finding a way to include the sun shades planned for the south facade while staying within budget.  The target budget was continually updated to keep everyone focused on the end goal. 

 

Building Information Modeling facilitated optimal delivery throughout the process, aided by full sharing of the model and prioritizing functionality rather than rigid standards.  Modeling helped reduce the entitlement and permitting duration by 75%, enabled much greater pursuit of what-if scenarios for every system, and provided more coordination between disciplines.  For example, PCS' structural steel design in the model (structure was modeled in 3-D using Revit and coordinated in Navisworks) was leveraged for precise site work dimensions and quantities, resulting in tighter estimates and bids.  The team was able to maximize clash detection and clarifications during design, helping keep RFIs below 100, a fraction of the typical number.  With earlier subcontractor selection, shop drawings were concurrent with design, and often eliminated the need for separate contract documents.
