Measuring downstream supply chain losses due to power disturbances

September 16, 2022
Author(s)
Douglas Thomas, Juan Fung
Power outages in the U.S. affect many firms' economic activity and are likely to result in downstream supply chain disruptions. This paper examines the impact of power disturbances in the supply chain for four industries: manufacturing, durable goods

A Framework to Evaluate the Cost-Effectiveness of Recovery-Based Design

May 24, 2022
Author(s)
Juan Fung, Yating Zhang, Katherine Johnson, Dustin Cook, Siamak Sattar
Modern building codes and standards are generally focused on safeguarding public health and safety by ensuring buildings meet life safety performance objectives following an earthquake event. Certain classes of buildings, such as hospitals and schools, may

In the wake of the COVID-19 pandemic small businesses made headlines as hard hit by customer losses, revenue declines, and business closures. Yet, the impacts have been felt disproportionately by small businesses that suffered interruption due to pre

The Total Costs of Seismic Retrofits: State of the Art

May 7, 2021
Author(s)
Juan Fung, David Butry, Siamak Sattar, Steven McCabe
This article presents the current state-of-practice with respect to quantifying the total cost to retrofit an existing building. In particular, we combine quantitative, qualitative, and heuristic data to provide a taxonomy for understanding the direct and

In 2020, there were 22 natural disasters with losses exceeding $1 billion each in the US (NOAA NCEI, 2021). Economic effects on the areas impacted directly were significant; Swiss Re estimated insured losses to be $83 billion, making 2020 the fifth

Eliciting Lessons from Small- and Medium-Sized Enterprises (SMEs) for Natural Disaster Resilience Planning and Recovery During the COVID-19 Pandemic: SME Complex Event Resilience

Jennifer F. Helgeson, Juan F. Fung, Yating Zhang, Alfredo R. Roa Henriquez, Ariela Zycherman, Claudia Nierenberg, David T. Butry, Donna H. Ramkissoon
Small and medium-sized enterprises (SMEs) make up 44% of U.S. economic activities and are the lifeline for many local economies, employing 59 million people in 2018 (SBA 2018, 2019). In the wake of the COVID-19 pandemic, small- and medium-sized (SMEs) are

Complex Event Resilience of Small- and Medium-Sized Enterprises: Natural Disaster Planning During the COVID-19 Pandemic

Author(s)
Jennifer F. Helgeson, Juan F. Fung, Alfredo R. Roa Henriquez, Yating Zhang, Ariela Zycherman, Claudia Nierenberg, David T. Butry, Donna H. Ramkissoon
Researchers at NIST and NOAA launched a longitudinal effort to assess Complex Event Resilience of Small- and Medium-sized Enterprises (SMEs). As a first step, a national survey of SMEs was conducted to better understand: 1. Past SME experience with natural

Associating Disaster Deaths with Risk Profiles

September 28, 2020
Author(s)
Stanley W. Gilbert, Jennifer F. Helgeson, David H. Webb, Juan F. Fung, Anand M. Kandaswamy
In this paper we set out to identify which “risk profiles” contribute most to deaths in disasters. A risk profile represents an identifiable group of people who would be at risk of death in a disaster through some mechanism. Four risk profiles were

Machine Learning Methods for Predicting Seismic Retrofit Costs

September 23, 2020
Author(s)
Juan F. Fung, Siamak Sattar, David Butry, Steven L. McCabe
Aging building clusters all around the world, especially in high seismic regions, will require a retrofit approach to improve the resilience of the built environment. One of the main challenges of retrofitting existing buildings is the associated cost

Community Resilience-Focused Technical Investigation of the 2016 Lumberton, North Carolina Flood: An Interdisciplinary Approach

August 1, 2020

John W. van de Lindt, Walter G. Peacock, Judith Mitrani-Reiser, Nathanael Rosenheim, Derya Deniz, Maria Dillard, Tori Tomiczek, Andrew Graettinger, Patrick Crawford, Kenneth W. Harrison, Andre Barbosa, Jennifer Tobin, Jennifer Helgeson, Lori Peek, Mehrdad Memari, Elaina Sutley, Sara Hamideh, Donghwan Gu, Stephen Cauffman, Juan Fung
In early October 2016, Hurricane Matthew crossed North Carolina (NC) as a Category 1 storm, with some areas receiving 0.38 m to 0.46 m (15 to 18 in) of rainfall on already saturated soil. The National Institute of Standards and Technology (NIST) funded

A Predictive Modeling Approach to Estimating Seismic Retrofit Costs

February 20, 2020
Author(s)
Juan F. Fung, Siamak Sattar, David T. Butry, Steven L. McCabe
This paper presents a methodology for estimating seismic retrofit costs from historical data. In particular, historical retrofit cost data from FEMA 156 is used to build a predictive model to estimate retrofit costs as a function of building

Social and Economic Components of Resilient Multi-Hazard Building Design

October 3, 2019
Author(s)
Katherine Johnson, Juan Fung, Siamak Sattar, Christopher Segura, Therese P. McAllister, Steven McCabe
In 2017, U.S. damages from natural hazard events exceeded $300B, suggesting that current targets for building performance do not sufficiently mitigate loss. The significant costs borne by individuals, insurers, and government do not include impacts from
