The Whole Life Appraisal Tool is a best practice approach for the public sector to optimize the performance of built assets throughout their entire life cycle. The tool provides a consistent method for comparing and reporting whole life outcomes for new projects, and can be used to identify areas for improvement in the procurement process. The tool includes a project input sheet, a whole life cost model, and a whole life comparison dashboard, and is designed to be flexible and adaptable to different types of projects. The Whole Life Appraisal Tool is intended to support the implementation of whole life appraisals within infrastructure investment, and is produced in partnership with Arcadis.
