Based on the premise that healthcare facility design and construction costs are escalating due to rework in (1) upfront planning, (2) programming, (3) design, and (4) permitting phases, a group of healthcare facility owners, architects, designers, contractors and state permitting personnel conducted a study to understand where the waste occurs. This study identified 158 process waste items. In this paper we categorize these 158 waste items using an existing taxonomy of rework and extending it as needed. The existing taxonomy of rework contains five categories: (1) human resource capability, (2) leadership and communication, (3) engineering and reviews, (4) construction, planning, and scheduling, and (5) material and equipment supply. The extension places waste items into three new categories: (1) planning, programming, and budgeting, (2) design planning and scheduling, and (3) design review. This research identifies what causes of rework are within the California healthcare facility design and permitting phases. Understanding these waste items provides a foundation on which to build new practices that avoid costly design and permitting delays.
