This report describes a continuation of an earlier study of the feasibility and costs of providing all-effects shelters in risk areas for an in-place shelter and a population relocation plan. The results of the earlier study indicated that a minimum of 6 months and 50 percent of national production of reinforcement and plate steel would be required to provide shelters for the population of risk areas for an in-place shelter plan. The purpose of the study described herein was to determine if advanced purchase and storage of materials would be a realistic measure for improving surge period shelter building capability. The results of the study show that there are three feasible programs for storing materials to support surge period shelter construction. Under the assumptions used in the study, the overall program cost is not significantly increased by the storage of materials. However, there may be severe shortages of labor to implement a surge period shelter program.
