An ad-hoc planning committee of the National Academies of Sciences, Engineering, and Medicine will plan and convene a workshop to bring together experts on predicting facility renewal requirements. The goal of the workshop is to suggest next steps in implementing recommendations made in the Academies’ 2023 report “Strategies to Renew Federal Facilities.” The workshop would provide a forum for presentations by policy experts, academics, and real property asset managers. The topics of the workshop are as follows:

1. Demonstrate the use of a geometric depreciation model as recommended for estimating renewal requirements. Compare the results with other approaches such as the NASA deferred maintenance model or the DoD recapitalization metric.
2. Identify recent research on the refinement of depreciation rates for structures and infrastructure, and discuss the potential for improving renewal estimates.
3. What is the state of the art for estimating facility service life, recognizing the differences in the economic, engineering, tax and budgeting contexts?
4. Describe some of the new data resources available for renewal cost research. What is the potential of massive assessment databases like the one maintained for DoD by the U.S. Army Corp of Engineers?

Proceedings of the workshop, summarizing the presentations and discussions, will be prepared by a designated rapporteur in accordance with institutional guidelines and disseminated widely.
