Engineers Nominated By American
Society Of Civil Engineers
Carrie Sturts, Ph.D., a civil engineer at Exponent Failure Analysis Associates in Bellevue, Washington, investigates construction delays and claims as well as building and material defects. As a doctoral candidate at Columbia University, Sturts explored the value of engineering services. In her dissertation she documented and discussed the current state of the industry and introduced tools that engineers can use to increase the perceived value of their products and services. As an engineer at Exponent, she investigates geotechnical and environmental projects. As a consultant with Exponent, Sturts analyzes complex engineering problems, communicating the results to colleagues and clients. A member of the American Society of Civil Engineers and the Society of American Military Engineers, Sturts has been active in mentor and public outreach programs.
Isa Mavi, a structural engineer with Parsons Brinckerhoff in New York, NY, worked to rebuild and restore subway service in Manhattan following the 9/11 disaster. Working day and night, Mavi developed design details for unforeseen conditions under incredible pressure; all in an effort to make sure that the contractor could maintain his aggressive schedule to restore service and rebuild the subway line destroyed in the collapse of the towers. Currently he is designing curved girder bridges for the Interstate 84/Interstate 87 Interchange Reconstruction Project in upstate New York. He is in charge of the superstructure steel for the project.
Nahid Afsari, a structural engineer with CH2M HILL in Milwaukee, Wisconsin, is designing part of downtown Milwaukee’s Marquette Interchange. As part of the $810-million replacement of a complex interchange linking three interstate highways near Marquette University, Afsari designed bridges for the half-mile-long east leg of the Marquette Interchange. She inspected the Hoan Bridge to check for structural defects. The 120-foot-high bridge had partially collapsed and was repaired a year earlier and her inspection helped safeguard against future incidents. Afsari’s diverse experience also includes design of a highway undercrossing that enabled a threatened species of snake to safely “get to the other side.”
Megan Lionberger, a hydraulic engineer with the United States Geological Survey in Sacramento, California, supports restoration and management of San Francisco Bay. For the planned restoration of thousands of acres of former commercial salt ponds to tidal wetlands, a crucial question is whether there is enough sediment to build and maintain wetlands as sea level rises. The bottom sediment of the Bay is a significant source of contaminants. Lionberger developed a tidally-averaged numerical model of sediment that is being used to simulate the long term fate of sediment and associated contaminants. By applying her model, Lionberger helped develop a sediment budget for San Francisco Bay. The next challenge is how to manage pond water level and salinity for maximum ecological benefit. To assist ecologists and resource managers, Lionberger developed a numerical model of water level and salinity in a salt pond. Additionally, she is conducting a field study to determine how much sediment and carbon a mature tidal wetland provides or removes from the Bay. |
