Abstract A severe winter storm in February 2021 impacted multiple infrastructure systems Texas, leaving over 13 million people without electricity and/or water, potentially $100 billion economic damages, and almost 250 lives lost. While the entire state was by temperatures up to 10 °C colder than expected for this time of year, as well levels snow ice accumulation not observed decades, responses outcomes from communities were inconsistent exacerbated prevailing social inequities that are...
In February 2021, Winter Storm Uri left 11 million people in Texas without power, caused widespread water outages, and inflicted billions of dollars damage. While the severity this event was primarily by electricity generator failures, it made worse decisions utilities state regulators before, during, after event. This study seeks to (1) evaluate procedures electric during Uri, (2) provide a set recommendations improve resilience energy systems preparation for future extreme weather events....
Purpose The COVID-19 pandemic caused significant societal changes and altered how much of the construction industry operates. This study investigates impacts pandemic-related changes, these may apply to different companies, which should continue post-pandemic. Design/methodology/approach We aim identify pandemic-driven that have affected workplace advantages challenges associated with them. then make recommendations for what could endure through beyond, under circumstances. To achieve this...
When engineers design and manage a building's water electricity utilities, they must make assumptions about resource use. These are often challenged when unexpected changes in demand occur, such as the spatial temporal observed during coronavirus (COVID-19) pandemic. Social distancing policies (SDPs) enacted led many universities to close their campuses implement remote learning, impacting utility consumption patterns. Yet, little is known how changed at building level. Here, we aim...
Hydraulic models can provide efficient and cost-effective ways for water utilities to evaluate changes in operating conditions (e.g., population dynamics, disasters), thereby increasing system resiliency during crises. Unfortunately, model development remains out of reach many because high software costs, data needs, or personnel requirements. This study seeks classify hydraulic modeling identify success factors challenges associated with development, determine whether a subzone larger...
The COVID-19 pandemic permanently changed the construction industry. Remote meetings are more commonplace, and technological advancements implementation accelerated. Although previous studies have identified types characteristics of such pandemic-induced changes, little is documented about how each change affected work performance. Here, we investigate industry changes associated impacts. In November 2022, a list was distributed to professionals working for US- or South Korea-based companies...

Engineered systems are designed for a specific operating context based on assumptions about the population served. In turn, management of these can be stressed during shifts (and corresponding demand shifts), such as those seen both discrete (e.g., hurricanes) and protracted pandemics) events. For instance, COVID-19 pandemic caused drastic changes in society, consequentially changing spatial temporal water use people worked from home. another example, Winter Storm Uri led to utility service...
When crises occur (e.g., disasters, public health emergencies), water infrastructure systems are often forced to operate outside the conditions for which they were designed. Hydraulic models can provide utilities with essential information in a crisis, allowing near real-time system performance evaluation and informing management response. However, hydraulic modeling remains inaccessible many due extensive data, software, skilled personnel requirements. Data needs particularly troublesome...
Water utilities are responsible for delivering safe, reliable drinking water to communities. In doing so, collect information from different sources gain constant insights into the state of systems. Among available data types, service problems that customers report critical information—especially during emergencies—which allow gauge impact system operations on resulting level service. While some increasingly and analyze customer reporting track key performance indicators (e.g., total...
Energy projects are essential to serving the world's growing energy demands. However, construction encounter controversy when community disagrees with development process or expected project outcomes. These conflicts can and often do lead schedule delays cost overruns, yet developers rarely prepared anticipate, mitigate, respond arising challenges. With this work, we aim model economic consequences of stemming from public opposition projects. We propose a framework determine potential costs...
In February 2021, severe winter weather in Texas caused widespread electrical blackouts, water outages, and boil notices. Water systems faced extensive challenges due to cascading failures across multiple interdependent infrastructure systems. utilities have since made considerable progress improving resilience extreme events, but ongoing remain. Through a qualitative analysis of semi-structured interviews with 20 large Texas, this study tracks the evolution three phases: storm immediate...
