Cost Estimates for the Seismic Retrofit of Federally Owned and Leased Buildings



Juan F. Fung, David T. Butry, Siamak Sattar, Steven L. McCabe


Presidential Executive Order 13717, Establishing a Federal Earthquake Risk Management Standard, encourages federal agencies to “enhance resilience…[to] future earthquakes” by evaluating and retrofitting existing federal buildings based on current existing building codes. We develop a methodology for predicting seismic retrofit costs based on observable building characteristics and the desired performance standard. Our approach is to train a series of regression models on a database collected for FEMA 156, Typical Costs for the Seismic Rehabilitation of Existing Buildings. The models vary in the level of data required; e.g., a decision-maker may not have information on building construction type. We use prediction error to quantify the effect of data availability on estimates.
