"Before the Roof Caves in Part II: A Predictive Model for Physical Plant Renewal"
Author: Biedenweg, Rick, and Alan A. Cummings
Published In: Proceedings of the 1997 Educational Conference
Date: 1997

Presentation at the 84th Annual Meeting in Orlando, Florida. Summarizes the Before-Roof-Caves-In model, a mathematical approach that predicts the cost and time of facilities renewal based on building sub-system life cycles and costs.  Discusses the initial 1980 model, benchmarks 15 year old predictions against actual Stanford University experience, and explores ways to update and enhance the model.  Describes the concept of adaption and how it can be incorporated into planning for high intensity research facilities.  Includes graphs and endnotes.
