Greenwood Department Chair in Civil, Construction & Environmental Engineering
Another successful year has passed for Iowa State University’s Department of Civil, Construction and Environmental Engineering (ISU CCEE). The achievements of our undergraduate and graduate students, the research and teaching contributions of our faculty and staff, and the significant work of our alumni and industry partners continue to place ISU CCEE at the forefront of accredited engineering schools. Our exceptional instructional environment is matched by cutting-edge research opportunities both on and off campus. Faculty members like Chuck Jahren, An Chen and Aliye Karabulut-Ilgu are transforming teaching methods using mobile augmented reality. Others, like Kristen Cetin and Bora Cetin, are bridging the gap between academia and industry by investigating how professionals solve authentic engineering problems and preparing guidance for faculty members and students based on those findings. In addition, our department finds new opportunities to pursue significant research. New faculty member Michael Perez is pursuing an off-campus stormwater research facility. Cross-campus partnerships are being fostered daily by researchers like Sri Sritharan, who recently played a part in securing funding for Iowa State’s Hazard Mitigation and Community Resilience Program.

We have successes to celebrate, as well as changes to which we can look forward. After three consecutive first place finishes, our Cyclone Energy team brought a fourth first place finish back to Iowa State from the ELECTRI International Green Energy Challenge. Former ISU CCEE chair and alumnus Lowell Greimann was posthumously awarded the Iowa State Foundation Order of the Knoll Faculty and Staff Award. Overall, the department more than tripled its number of National Science Foundation projects between 2017 and 2018, with 14 projects and more than $1.6 million in funding. In the past year, ISU CCEE conducted over $16 million in sponsored research. Our graduate program enrollment and research activities/expenditures continue to increase. In July, I stepped down as department chair. I want to welcome David Sanders to ISU CCEE as the incoming Greenwood Department Chair in Civil, Construction and Environmental Engineering. David is an ISU alumnus and has a wealth of research and educational experience, which you can read about on the next page. In the following months, we look forward to his leadership as he continues to encourage the legacy for which our department is known. All of these positive changes would not be possible without the support of external partners, our advisory councils and generous donations of time and resources from you. Thank you for your continued dedication to the success of ISU CCEE and its students, faculty, staff and mission.

David Sanders joins ISU CCEE as Greenwood Department Chair AMES, Iowa – David Sanders (pictured left) has been named the Greenwood
Department Chair in Civil, Construction and Environmental Engineering. His appointment began July 1, 2018. “Engineering is about problem-solving and people,” Sanders says. “Civil, construction and environmental engineers are uniquely positioned because the systems we design and the problems we solve directly impact people.” Sanders comes to Iowa State from his previous position as a university foundation professor at the University of Nevada Reno’s Department of Civil and Environmental Engineering. He is a fellow in the American Concrete Institute (ACI), the Structural Engineering Institute and the American Society of Civil Engineers. He has been active in teaching, research, university service and professional organizations, including being a member of the Structural Concrete Building Code Committee and a chair of one of its subcommittees. Sanders is a 1984 civil engineering alumnus of Iowa State University. He went on to earn his master’s and doctoral degrees in structural engineering from the University of Texas at Austin. “I have a deep affection for this department and this institution and am excited about what it can offer students and the communities we serve,” he says of Iowa State. “It satisfies a desire to reorient my career from one where I was doing the research and teaching to a career where I’m helping others excel in their research and teaching.” Sanders’ research has centered on the behavior and design of structural concrete with an emphasis in the seismic design of bridges. He has earned over $15 million in research as a principal investigator or co-principal investigator. He has published more than 300 research publications and given more than 200 technical presentations. He is an active teacher and has mentored 57 successful doctoral and master’s students as an adviser or co-adviser. In his first months at Iowa State, Sanders wants to take on long-term strategic planning. This will include engaging department leadership, faculty, staff, alumni and departmental friends to formulate a vision of where the department wants to be in the coming years. An important aspect of the strategic plan is developing methods for advanced teaching, increasing research and expanding global impact. “The department is already engaged in innovative teaching and cutting-edge research,” Sanders says. “I am excited about sharing that story with others. My role as department chair is to help get the resources and tools in the hands of our faculty and students to make this department even better.” 2

Alipour awarded National Science Foundation CAREER Award By Kate Tindall Published April 9, 2018
AMES, Iowa – In March, the National
Science Foundation (NSF) awarded Iowa State Assistant Professor Alice Alipour a Faculty Early Career Development (CAREER) Award. Alipour is the principal investigator of the project, “Resiliency of Electric Power Networks under Wind Loads and Aging Effects through Risk-Informed Design and Assessment Strategies.”
Everyday impact
During this five-year, $500,000 project, Alipour's goal is to create more resilient electric power networks (or EPNs). “Electric power is essential for everyday life and the economy,” Alipour explains. “In recent years, with extreme weather events that have happened, we have seen many outages. Some of these losses are attributed to the vulnerabilities in the physical infrastructure of the power system.”
System analysis for extreme events
Alipour uses various examples, such as the Northeast Blackout of 2003 or, more recently, the devastating impact of Hurricane Maria on Puerto Rico. The type of EPNs that 4

fail during large-scale blackouts carry high-voltage electric currents. When the transmission of power fails, daily life can come to a grinding halt. “You analyze a system or a known collection of structures together, and you estimate what is the effect of the failure of each one of them in the communities that they serve …,” Alipour says. “Looking into these consequences, you can measure which structures are more critical to your system. Then you will have a justification to design them to higher standards, rather than what is required by [national or local electric] codes.”
Alice Alipour (pictured right) wants to look not just at individual transmission towers, which is a conventional approach to improving EPNs. She also wants to explore system-level consequences. (Photo by Christopher Gannon)

Poleacovschi earns fall 2017 PIRS Research Seed Grant for micropolitan resilience studies By Kate Tindall Published Mar. 26, 2018
AMES, Iowa – Cristina Poleacovschi,
assistant professor of construction engineering and principal investigator of the research project, “Resilient Micropolitan Areas: Evaluating Coping Mechanisms After Economic Shocks,” earned one of the four fall 2017 Iowa State Presidential Interdisciplinary Research Seed (PIRS) Grants. “The idea behind this project is finding what makes communities resilient,” Poleacovschi says. “The way we define resiliency is that, when an economic shock happens, a community recovers.”
Helping communities cope
Poleacovschi and her colleagues
propose to study the many factors that make micropolitan areas resistant to the detrimental effects of economic shock. “Job recovery shows us if the community is resilient to economic shocks,” Poleacovschi explains. The team, which consists of faculty from engineering, computer science, sociology, and community and regional planning, will explore capacities of resiliency in addition to job recovery.
Micropolitans
(population centers between 10,000 and 50,000 individuals) are studied less frequently than rural or urban areas. They have the capacity to satisfy the needs of those who want to live between rural and urban areas. This project will explore the effects of economic shocks, instead of serving as a disaster study (which is more common). “Sometimes, as engineers, we talk about the infrastructure as if it is separate from the communities,” Poleacovschi says. “But history has numerous cases where the way infrastructure is put together does affect communities.”
As Poleacovschi points out, the interdepartmental research is unique for several other factors as well. Micropolitans
Quick Look Social capacity refers to the social capital of community networks. Physical infrastructure capacity refers to quality of area infrastructure, and institutional capacity refers to the level of non-profit, government and business services. The research team believes the study of each in struggling or resilient micropolitans will provide a holistic approach to understanding resiliency. The figure to the right illustrates a plan to advance from PIRS to National Science Foundation (NSF) research. Meet Modern Challenges

Researchers transform teaching of structural analysis through mobile augmented reality By Kate Tindall Published Sept. 6, 2017
AMES, Iowa – “Students are motivated
when things make sense and are relevant,” says Chuck Jahren, ISU CCEE’s Construction Engineering Professor-in-Charge. That is why Jahren and a team of researchers are working to bring mobile augmented reality (AR) to classrooms. The National Science Foundation has awarded the group nearly $300,000 for its project, “Collaborative Research: Transforming Teaching of Structural Analysis through Mobile Augmented Reality.”
How it works
Currently, the team is developing computer-generated AR models. Those models superimpose on surfaces using a tablet or iPad®. Students open an application, hold the tablet up to a campus structure, see the underlying components, and observe how structural elements behave under different types of loading conditions. An Chen is an assistant professor of structural engineering and the principal investigator of the project. He teaches Civil Engineering Structural Analysis I (CE 332), the class in which the researchers will ultimately test their AR applications. “We envision this will not replace everything in the classroom. We believe this will be a resource, a supplementary material 8

that the instructor or the students can choose to use,” he says.
Testing
Quick Look Iowa State University researchers are bringing augmented reality to class learning. “The idea behind augmented reality is that it addresses different learning styles because it gives different experiences to students,” says Aliye Karabulut-Ilgu, a lecturer in pedagogic aspects of this research.
After the development of applications, the researchers will test the effectiveness of AR as a tool for learning. In a controlled environment, one group of students will use the applications to learn a structural engineering topic. Another group will learn the same topic through traditional lecture methods, which include concept presentations through 2-D visuals and problem solving. The project is estimated to last through July 2019.

Concrete for taller wind turbine towers passes tests, could help expand wind energy nationwide By Mike Krapfl Published May 24, 2017
AMES, Iowa – “Taller turbine towers can
enable wind energy production in all 50 states, including those in the Southeast," says Sri Sritharan, the Wilkinson Chair in Iowa State University’s College of Engineering and the interim assistant dean for strategic initiatives. Winds at higher elevations, generally, are stronger and more consistent, even in wind-rich states such as Iowa and Texas. In fact, Sritharan says a 20-meter increase (about 66 feet) in tower height creates a 10 percent boost in Iowa energy production.
Hexcrete And so Sritharan has been leading development of new concrete tower technology capable of reaching those heights. He calls the technology “Hexcrete,” which
can also be combined with steel tubular technology to create hybrid wind turbine towers. The basic idea of Hexcrete (pictured below, courtesy Sritharan) is that it’s assembled from precast panels and columns made with high-strength or ultra-high-performance concrete. Those panels and columns can be cast in sizes that are easy to load on trucks. They are tied together on-site by cables to form hexagon-shaped cells. A crane can stack the cells to form towers as high as 140 meters (about 459 feet). Sritharan has just completed a study of Hexcrete supported by the U.S. Department of Energy, $83,500 from the Iowa Energy Center and $22,500 of in-kind contributions from Lafarge North America Inc. of Calgary, Alberta, Canada. The project’s industry partners also include the Siemens Corp.’s
Corporate Technology center in Princeton, New Jersey; Coreslab Structures (OMAHA) Inc. of Bellevue, Nebraska; and BergerABAM of Federal Way, Washington.
A prototype tower
With the lab and economic studies showing positive results, Sritharan says he’s working to form a university-industry partnership to build a prototype Hexcrete tower. He says the tower would likely be 100 to 120 meters high (about 328 to 394 feet). And it could be entirely Hexcrete or it could be a hybrid tower with a Hexcrete base and a tubular steel top. With appropriate financing, Sritharan says a prototype tower could be built in about a year. It could even be built in the southeastern United States.
Quick Look A research team led by ISU CCEE Structural Engineering Professor Sri Sritharan has just finished an 18-month, $1 million study of concrete technology for taller wind turbine towers. Sritharan says lab tests demonstrate the technology will work. Economic studies also say the technology can be cost competitive. Sritharan says the taller towers could enable wind energy production in all 50 states. Meet Modern Challenges

Interdisciplinary student seeks solutions to overseas water crisis By Kate Tindall Published June 1, 2017
AMES, Iowa – After waking up in her home in Sana’a,
Yemen, Sahar Da’Er would turn on the faucet. She couldn’t rely on anything coming out of the pipe, though. “We’d wake up in the morning and, sometimes, you’d open the tap and you wouldn’t get water,” she recalls. “We had to wait for water tanks to come and fill up our tank.” Da’Er is a doctoral student at Iowa State University (ISU). She was awarded an interdisciplinary scholarship from ISU’s Graduate College and ISU CCEE to pursue research of sustainable wastewater treatment. Along with Kaoru Ikuma, an environmental engineering assistant professor at ISU CCEE, Da’Er will seek solutions to water crises like the one that has rocked her homeland.

There, she monitored the effects of various water harvesting projects during a steadily growing humanitarian crisis. “You see children dying,” she says. “They are basically dying from waterborne diseases.” Da’Er knew she could make the most impact in Sana’a if she were a researcher and a professor. She decided on ISU after happening on a news story about Ikuma’s work. “What really attracted me the most is what she said about the earthquake in Japan and how they didn’t have water,” Da’Er says. “That hit home for me. That sounded like me.”
says. “I think it allows them to be a little bit more creative.” “The science and the process are both very important,” Da’Er adds, comparing engineering to a process. “The science is needed to understand the process. And the process needs the science to function.” With her experience and drive, Ikuma has found a dedicated student in Da’Er. “She strongly recognizes the need for water—safe water—and wants to go above and beyond in her education and research to better understand it and ultimately become a leader in the field,” Ikuma says.
Wastewater treatment The pair are researching the use of algae as a cost-effective solution for wastewater treatment. “We would use a biofilm system based on algae for sustainable wastewater treatment,” Ikuma explains. “The idea would be to use algae, to allow them to photosynthesize and release oxygen. Then the other bacterial cells in the wastewater would do the rest of the treatment.”
Importance of interdisciplinary research
Both environmental engineering and environmental science researchers will work with Ikuma and Da’Er in the coming months. “This kind of fellowship really allows students to go above and beyond the typical research that’s already being done,” Ikuma

Equity and equality among construction engineering faculty at Iowa State By Kate Tindall Published Jan. 16, 2018
AMES, Iowa – The 2017-2018 school year
marks the first time regular faculty positions in Iowa State University’s Construction Engineering Program (ISU ConE) are equally filled by both men and women. This growing diversity lends increasingly unique backgrounds that guide each student’s journey to a successful engineering career. “We all have the same goal of turning out well-rounded construction engineering students,” says Associate Professor Jennifer Shane. “Having different faculty role models is important to show that there are different paths to solving problems and interacting with others.”
History

Now, the program is comprised of 10 regular faculty members, five of whom are women. Shane, who has served as a mentor to both engineering students and faculty during her 12 years at Iowa State, sees growing diversity in minority representation within the program, as well as a more diverse set of student organizations offered by the department.

Engineers Without Borders – Iowa State University Chapter brings water to Ullo, Ghana By Kate Tindall Published Jan. 30, 2018
ULLO, Ghana – Ullo is a small village.
So small, in fact, that you may have trouble finding it with a Google Maps search. This small village in the northern region of Ghana is where two civil engineering students spent their winter break. And it’s where Iowa State University’s Engineers Without Borders (ISU EWB) student organization has been traveling for the last several years, establishing relationships with the community and working on a critical water distribution project.
The people of Ullo
Quick Look Civil engineering students are using their problemsolving skills while working with the Iowa State student organization Engineers Without Borders. In December 2017, they drilled mechanized wells for safe water sources in northern Ghana. 16

“The people are definitely the driving force behind it,” says Kevin Prince. “The people that you meet there in Ghana, they are absolutely wonderful. It’s incredible how happy they are, every moment you are with them.” Prince is a senior studying civil engineering. He says ISU EWB students have been traveling to Ullo since 2014 to establish a new water distribution system that the local high school and community can use. Kevin Prince (middle, in yellow shirt) walks with children in Ullo. EWB members get to know the community members while working on water distribution centers. (Photos courtesy Kevin Prince)
“Currently, the water situation has been very extreme … students are struggling with their academics because of the water issue,” he says. “They often spend hours, either in the morning or at night, and some even in the middle of the night, going to the local hand pump boreholes.” ISU EWB works with Engineers Without Borders USA to partner with Ullo on the water distribution project. In 2016, ISU EWB members worked on determining a site to drill and secure water.
Solving problems with safe water The project could solve a host of issues for Ullo citizens. For the local high school, which can house up to 1,500 boarding students at a time, it could help with the overall learning environment. In conversations with school leadership, Prince was told that, “if you bring us consistent water, you’ll solve 90 percent of the school’s problems.” “It’s hard to tell someone to not sleep
in class or to make sure to get their homework done when they are just struggling to get enough water,” he explains. During this most current winter break, the group was able to secure a water source and began helping Ullo form a project management and operation maintenance team from its local leadership. The borehole that the group selected was 42 meters deep and pumped at 75 liters per minute for 24 hours during a constant rate test. Members will monitor the site during the upcoming dry season to evaluate the well, which lies over a recharging aquifer. Kylar Oh is also a senior in civil engineering. This was his first trip to Ullo. “By supplying this to the high school itself, we relieve some pressure from the community,” he says. “If we can expand this system, it would make their lives easier. I hope that, when students from our club go over there, they appreciate the struggles that the community goes through and can bring that understanding and that empathy back to the other students of the club.”
Changing lives Both Prince and Oh will be graduating in 2018. But they are eager to hear from students who will travel to Ullo again to monitor and evaluate the water quality of the mechanized well site. “The best part of this work is knowing that what you are doing is actually changing lives,” Oh says. “It’s not for the sake of money or a paycheck, but it’s of a desire to actually help people. That’s what I like most about it and what I find most fulfilling.” You can read more about ISU EWB's water distribution system project by visiting the organization’s website, https://www. stuorg.iastate.edu/site/ewb. During this most current trip, seven students traveled to Ghana with their adviser, Rameshwar Kanwar, a distinguished professor in Iowa State’s Agricultural and Biosystems Engineering Department. Ullo citizens gather around a hand pump well to draw water. EWB members hope to supplement these hand pump wells with a mechanized well system.

Innovative Geopier® Systems gets start with ISU alum: mentoring has lasting impact for CCEE student and professor By Kate Tindall Published Dec. 14, 2017
Quick Look Do you have a mentor? This civil engineering alumnus and emeritus professor know how to keep an innovative relationship going strong for decades.

Build Connections
AMES, Iowa – When you walk down
Engineering Row on Bissell Road that runs along the west side of Iowa State University’s (ISU) campus, you will notice a large construction site just west of Marston Hall. In 2020, this groundwork will give way to a new Student Innovation Center. What most passersby don’t know, though, is the story of innovation behind the technology being used to build this center. Here’s one story …
The start of collaboration
Take a look at the photo to the left. You’ll see two specialized implements. These implements make up the Geopier GP3® System, and they have unique ties to ISU. Not only have they been utilized on the construction site of the Student Innovation Center, but they are the brainchild of an ISU grad. Nathaniel “Nat” Fox, who earned both his doctoral and master’s degrees in civil engineering from Iowa State, first came to ISU in 1964. Fox had held an officer position in the Army Corps of Engineers in the early 1960s and was looking for the best graduate school. That’s the first time he met Professor Richard “Dick” Handy, an ISU CCEE faculty member. “What got me interested in the first place was his (Handy’s) reputation at Iowa State University and in the field of geotechnical soil engineering,” Fox says.
More than a name Handy’s reputation wasn’t the only thing that convinced the young engineer to choose him as a major professor. Handy’s tendency to engage students in real-world research was well-known. He also listened to the goals of his students. He remembers one of the first goals Fox confided in him. “He said that one of his major ambitions was to invent something,” Handy says. At that time, Handy was working on the original prototype of what would become
the Borehole Shear Tester. “I handed it to him and said, ‘Well, see what you can make out of this,'” Handy says. It was the first of many times the professor would challenge Fox to think outside of the box when it came to geotechnical advancements, and Fox was ready for it. As Fox continued his studies under the guidance of Handy, a seed was sown for years of respect between the two.
served as a mentor, you’ll hear this answer … “He’s the number one mentor in my life,” Fox says. “He has been and still is.” The Geopier® ground improvement system is used to reinforce soils of various qualities while providing a firm, safe foundation for structures. Purchased by Tensar Corporation in 2002, Geopier® Systems is now used in 33 countries worldwide.*
Collaboration beyond campus
Keeping connections strong
After graduate school, Fox served in the United States Army as a chief engineer in the 559th Engineer Detachment (Terrain Division) during the Vietnam War. He kept up correspondence with Handy and fellow ISU associates to ask advice on several projects pertaining to soil stabilization for highways, roads, airfields and airstrips. “They were unbelievably critical to helping my work in Vietnam,” Fox says. “You couldn’t ask for a better relationship than that.” Following his service in the Army, Fox and Handy worked on a Federal Highway Administration project to develop a stepped blade. Both men note that the stepped blade, which could measure lateral stress in soils, was an important step toward the development of Geopier® Systems by Fox in 1989. Just as before, Fox and Handy kept up a strong line of communication. They asked questions of each other and advice from each other. When you ask Fox whether Handy has
Soon, the Student Innovation Center will bustle with activity. In the midst of new collaborations is a history of student-faculty partnerships. You just have to know where to look. “It gives an advantage to both parties,” Fox says of his collaborative experience with (now) Emeritus Professor Handy. As for the main lesson he takes from his time studying geotechnical engineering under Handy’s mentorship? “Never stop,” Fox insists. “Always try to do better, to do the best.”

The civil engineer is, in his own words, a “problem solver.” For the first 21 years of his career, Kuhn solved engineering challenges as a municipal engineer and successful businessman. But about three years ago, he branched out into a different field entirely. Kuhn opened his first restaurant, Urbandale’s The Beerhouse. He followed that with a venture into a new metro trend … food trucks. Those two interests have intertwined at The Hall, where Kuhn and his associates are using local food trucks as satellite kitchens and creating community in the bargain. When you walk in on a Friday night, you see hundreds of people mingling at long tables constructed two feet in width (pictured to the left). “You’re already in each other’s personal space,” says Kuhn with a smile. “It’s going to get really awkward if you don’t start having a conversation.” That, of course, is a major concept behind The Hall. “We have a community focus,” he says. “One of our goals is to rebuild community—build it and rebuild it – and we
do that through conversation.”
The Kitchen
Rebuilding community doesn’t stop in The Hall. Walk through the restaurant/bar area, and you enter a space that Kuhn calls The Kitchen. A past president of Des Moines’ Legion of Food (food truck association), Kuhn got his start providing food to the homeless with other food truck owners several years ago. “That’s really when I became more in tune to the homeless population here in the metro,” Kuhn says. “It was my experiences with the homeless and the food trucks and beer industry that we’ve now packaged up into one big model.” Major construction of The Kitchen began in January 2018. The Kitchen will function to give at-risk youth ages 18 through 24 the chance to learn culinary skills from Des Moines’ food truck chefs. It’s part of a new non-profit that Kuhn and his wife founded this year called the Justice League of Food (a
play on the Justice League of America, for comic buffs). Kuhn explains that food trucks servicing The Hall become members of The Kitchen and get to rent kitchen space at a competitively low rate. In return, food truck chefs will train apprentices in culinary skills, produce weekly hot meals in The Kitchen using apprentice staff, and pay the apprentices’ wages to make meals for regional distribution to various senior centers and shelters. Kuhn has partnered with groups like Partnership for a Hunger Free Polk County in the hopes that more food can get to more people in need.
Changing the game
Drive down Railroad Avenue in Valley Junction, and harbingers of the district’s historic past grab your eye. The same can be said for The Hall at 111 South 11th Street. From the food to the brews to the camaraderie and philanthropic mission, very little about The Hall is ordinary. In all, nine food trucks service The Hall on a calendar rotation. Kuhn’s goal is to have your food and drinks out to you as quickly as it takes your friends to order. To accomplish this, servers converse with visitors and use digital technology to send individual orders back to the kitchen or bar in real time. Diners can also order via kiosks or via The Hall mobile app. “We have changed the game of food trucks and beer halls through technology,” Kuhn says. “We have changed the game of customer service in beer halls and brick and mortars.”
Following through “It’s complicated and simple all at the same time.” That’s the way Kuhn sums up the concepts of The Hall and The Kitchen. But for this ISU engineer, following through is familiar. He first picked up the habit in college. “I learned to think critically," he says. "And a college education, in general, is about following through ... Part of me believes that the college experience – and Iowa State in particular – is about teaching people how to follow through.” In founding a new non-profit and business, Kuhn has forged new partnerships and built a new team. While looking to the future of food and philanthropy in the metro, he’s reminded that relationships and experiences build on each other. “I wouldn’t be doing what I’m doing today had it not been for all of these crossroads, and it started with Iowa State University and getting a degree in engineering,” he says.

Drones take off as trend in engineering industries – an alumni feature By Kate Tindall Published May 24, 2017
Quick Look Technology is changing the way engineers tackle challenges in the field. Iowa State civil and construction engineering alums weigh in. This story is a result of alumni suggestions concerning possible departmental story content. 24

DES MOINES, Iowa – Matt Goodhue and Jenny Herrera are project engineers for the Iowa business unit of The Weitz Company. Goodhue graduated from ISU in 2013 with a degree in construction engineering. Herrera studied civil engineering and graduated in 2016. Together, they have logged nearly five years of drone operations experience.
Intro to UAVs
How did these alumni, who had no experience with drones prior to graduation, pick up these skills? In 2013, Goodhue (pictured on pg. 24) started his career with Weitz. He was working on a senior living community project in Minnesota. One day, he was watching a YouTube video of a drone operator. Goodhue found the video so interesting that he forwarded it to his site superintendent. At the time, Weitz was paying a fee to an aerial photographer for progress photos of the site. Goodhue saw an opportunity to use a drone (or unmanned aerial vehicle, UAV) to take aerial photography and video. “What it allowed us to do is see the whole project at once,” Goodhue says. No small feat, as the senior living complex stretched across a 46-acre site. “It was helping us with our schedule and logistics in our planning meetings, both internally and with the subcontractors,” he says. “We could communicate better and manage our schedule better.” Herrera (pictured on pg. 25) also started working for Weitz right after college. When the company announced that it was searching for employees interested in becoming UAV pilots, she leapt at the opportunity.
“We’re always trying to find the next big thing,” she says. “How can we be safer? How can we be more efficient? How can we continue to be the best in class?”
Safety, efficiency, accuracy Herrera compares older construction photographic techniques to the 360-degree panoramic photo on a cell phone, in that images sometimes can look skewed. With a drone, difficult angles or towering heights present less of a challenge. The engineers also say UAVs have a huge positive impact on safety. Take this example: Herrera worked on the Hilton Des Moines Downtown, a convention center hotel to be attached to the Iowa Events Center. When Weitz employees started positioning post-tension cables in concrete decks, Herrera used UAV technology to document the exact positions of the cables. When curtain wall was going up on the sides of the building, safely documenting the process was key. “It’s not going to be a safety risk for me to fly the drone up to the eighth story and get a picture, as opposed to trying to get a person up there,” she explains. Goodhue, who moved to Des Moines in 2016, adds that every UAV operator at the company must meet specific standards. The list includes safety protocols and preflight checks aimed to keep the operator, fellow engineers, and the UAV itself safe.
experienced and novice engineers. “It’s changing so much that it’s harder for lots of people to keep up with it all,” Goodhue says. “If you don’t love technology and love experimenting with it, I think it could be a little frustrating to have all this new technology.” Another frustration can be finding the best technology in a world flooded with new gadgets and software. “I think, in the long run, there’s going to be a way to make a lot of things easier. That doesn’t necessarily mean the first thing that comes out is going to be the best option,” Herrera says. Since technology is around for the long haul, both alums encourage fellow engineers to stick with it, even when the learning gets tough. “I feel in the end, [technology] makes things a lot easier,” Goodhue says.

Technological stumbling blocks The changes brought to construction sites by UAVs can be exciting. But Herrera and Goodhue admit that new technology can also throw a mean learning curve at both Build Connections

Iowa State University alumni take leading roles building new City of Ames Water Treatment Plant By Kate Tindall Published Aug. 17, 2017
AMES, Iowa – Engineers Kris Evans, Lance
Aldrich and Jenny Ruddy will have a big effect on Ames citizens for years to come. Whenever someone turns on the faucet, he or she will come into direct contact with the work of these three Iowa State University (ISU) alumni. On Aug. 26, 2017, the City of Ames hosted the grand opening of its newest water treatment plant. The plant is located on the east end of town on 13th Street. For the last decade, the City of Ames, in conjunction with

FOX Engineering, designed and built the brand new plant.
The new plant
“You feel like you’ve been handed a huge responsibility,” says Evans, the environmental engineer for the City of Ames. “The other plant lasted 100 years. Going into design, we consciously had to think about the future.” Evans earned her bachelor's (B.S.CE’98), master's (M.S.CE 2000) and doctoral degrees (Ph.D.CE 2004) in civil engineering from ISU. The century-old water treatment plant has served as her work base since she began at the city in 2007. “It’s sad to see a facility that’s been used for about a hundred years start to come to a close,” she says. “At the same time, it does create a really exciting opportunity: a brand new facility [with] lots of opportunity to share the process and the treatment plant with people. It’s sad on one hand, and it’s extremely exciting on the other.”
Local project, local impact
Aldrich (B.S.CE’94) and Ruddy (B.S.CE 2008, M.S.CE 2009) are both environmental engineers for FOX Engineering. For these two community members, one of the neatest parts of the project lies in its local roots. “First and foremost, the project brings high-quality drinking water to the community of Ames,” Aldrich, who is top principal at the firm and the senior project manager in FOX Engineering’s water and wastewater group, says. “ … This provides future opportunities in Ames for industry and economic growth.” Both Aldrich and Ruddy worked with contractors to test the plant processes and prepare for the open house in August. A $70-million project (including construction, design, land, etc.), the new plant has a treatment capacity of 15 million gallons of water per day (MGD).
Quick Look At the closure of a nearly 10-year project, three local environmental engineers are making a lasting impact on the Ames community.
Expert advice
All three engineers take lessons from their time at ISU to work each day. They all remember completing team projects and intense course work (each alum found this college experience helpful during the treatment plant process). Ruddy, who is a project engineer in FOX’s water and wastewater group, says internships are also a game changer for up-andcoming engineers. “Definitely pursue internships during as many summers as you can,” she says. “ … It’s a good way for students to get to know companies and for companies to get to know students. It opens pathways.” Aldrich encourages students to take on classes in various focus areas. Whether it’s transportation or structural or mechanical engineering, it’s important. “Especially as an undergraduate, keep the breadth of classwork pretty wide,” he advises. Finally, Evans stresses that communication skills can make the difference between getting ahead—and being left behind. “Get any and all opportunities to present and talk in front of groups,” she says. Multiple ISU alumni and student interns from various majors were involved during the planning and construction of the treatment plant.
