abstract={Healthcare projects are complex commercial building endeavors, and re-purposing an office building into a healthcare facility within a tight time frame can be especially risky. Conventional management practices are insufficient for the design and delivery of complex capital projects. However, decades of research have demonstrated Target Value Delivery's effectiveness in mitigating risk in complex project design and delivery. While TVD tools are often disseminated through cases that focus on the overall TVD process, there is a need to focus on a less well-known step implemented upstream of design, known as “plan validation.” The purpose of this paper is to share how an owner and stakeholder team managed to mitigate risk using plan validation for the adaptive reuse of a complex multi-building healthcare project. The owner engaged general contractors and design partners already experienced in TVD practices. The team collaborated using lean methods such as an IFOA contract, innovated by exploring alternatives early on during interactive big room meetings, developed prefabrication solutions, and implemented takt planning and the Last Planner System of Production Control during the plan validation process. This paper qualitatively documents from stakeholder’s comments how lean methods contributed to the owner’s ability to confidently proceed with the project. },
