Yelitza Cede帽o was enthralled. The furious, but focused activity in the college鈥檚 structure lab arena was fascinating to Cede帽o, who was president of the 51本色 student chapter of American Society of Civil Engineers.
鈥淚 just saw students running in the arena and they were building something,鈥 Cede帽o recalled. 鈥淚 was like, 鈥榃hat is going on? They were so focused 鈥 they were putting bolts in stuff. They were drilling.鈥
Cede帽o, who was at Auburn 51本色 for the 2022 student concrete canoe competition, was exploring other areas when she happened upon the steel bridge competition. She鈥檇 never seen it before because COVID-19 had restricted competitions and travel.
鈥淚t was love at first sight,鈥 Cede帽o said laughing. 鈥淚 went to my faculty adviser and said, 鈥業鈥檓 going to be captain of the steel bridge competition next year!鈥欌
That 鈥渨ild statement鈥 as Cede帽o describes it, set in motion a nearly yearlong process that included assembling a team, securing materials and designing and fabricating a 23-foot-long steel bridge intended for pedestrian and motorists to cross a 7-foot river.
The American Institute of Steel Construction and American Society of Civil Engineers sponsor the steel bridge competition as an annual event intended to demonstrate knowledge and skills of future generation design professionals.
At the ASCE 2023 Gulf Coast Student Symposium, held March 9-11 at the 51本色 of South Alabama in Mobile, UNO鈥檚 team beat out 15 other universities from Louisiana, Mississippi and Alabama.
The team included: Gavin Trinh, Maria Umanzor, Perry Newman, Cede帽o, Steven Hernandez, all civil engineer majors and Francisco Espinoza and Alonso Milon, who are majoring in construction management.
Cede帽o was team captain and project manager鈥攐ne with very little experience, she said.
鈥淣one of us had any experience,鈥 said Cede帽o, noting the last time the 51本色 competed in the contest was in 2018. 鈥淪o, we were starting from nothing. A brand-new team.鈥
Cede帽o did tap into the knowledge of a former UNO steel bridge competition captain and even talked with other competing schools to get information. Her team worked on the project from November to mid-February.
鈥淭his is extracurricular, this is on top of class, jobs, etc.,鈥 Cede帽o said. 鈥淲e were doing this because we love it. We came in on weekends or in between classes. It was a lot of work.鈥
The competition includes structural costs based on total weight; construction cost based on the number of builders in a timed race to erect the bridge; and safety, with time penalties for dropping bolts, nuts or tools and stepping outside the construction zone or in the river. Aesthetics and the use of materials that promote robustness without wastefulness are also judged in overall performance.
UNO was up against some veteran teams, Cede帽o said. The top two finishers in the competition would advance to the national competition in California.
鈥淔rom the start we knew we had two rivals. One that always dominated this area: LSU, and then we saw another rival was the 51本色 of South Alabama鈥攖he host,鈥 Cede帽o said.
The Region 5 competition was the first one held, and UNO was tagged as the first team to compete, she said.
鈥淲e were the newbies! We didn鈥檛 have any experience last year and we didn鈥檛 even get to see another team do it,鈥 Cede帽o said. 鈥淚t was crazy 鈥 we did our best.鈥
The competition allows for 30 minutes. UNO鈥檚 construction time was 20 minutes. Then the bridge鈥檚 structural design was tested by adding weight during the lateral load test. They passed 鈥渨ith flying colors,鈥 Cede帽o said.
鈥淲e went to the vertical load test, the bridge had to hold 2,500 pounds with a maximum deflection of 3 陆 inches,鈥 she said. 鈥淲e had 1.05 inches, so that鈥檚 like 1 inch compared to the 3, so we were good!鈥
South Alabama swept through the construction, doing well as expected. Cede帽o and her teammates watched from the sidelines as LSU worked quickly on the floor. They completed construction in 15 minutes with no penalties, confirming why they were considered a dominant team in the region.
鈥淭heir time was ridiculous 鈥 then they passed the lateral test,鈥 Cede帽o said.
Then came the vertical load test. The team must add 12.5-pound angle weights to the bridge until it reaches the maximum load of 2,500 pounds. The LSU team had added all but five of its angles and the arena had grown quiet, Cede帽o recalled.
鈥淭hen the bridge broke. Their bridge鈥攂roke,鈥 Cede帽o said, still amazed several months later. 鈥淲e have a chance to go to nationals!鈥
As it turns out, the UNO team not only earned its ticket to nationals, but the team also won the overall competition and placed first or second in a majority of the categories.
鈥淭his is a very special win since it is the first time competing in steel bridge since 2018,鈥 said Gianna Cothren, professor of civil engineering and ASCE faculty adviser. 鈥淲ith their best design, many hours of welding and construction, and a last week of practice in our structures lab basement, our team pulled off the unusual feat of winning first place overall with no experience.鈥
鈥淲e received many congratulations and awe from other universities that usually dominate this event,鈥 Cothren said.
Though UNO鈥檚 civil engineering program is small relative to some of the universities they competed against, Cothren said they were fortunate to have strong support from UNO President John Nicklow, Dr. Robert A. Savoie College of Engineering Dean Lizette Chevalier and the local civil engineering industry.
鈥淥ur students have unbelievable perseverance to make things happen,鈥 Cothren said.
Cede帽o, who graduated in May, said she is pleased with her team鈥檚 accomplishments and the legacy they鈥檝e left for others, although they did not win at nationals.
鈥淚鈥檓 proud to say that I have created a path for the next people to come,鈥 she said.
UNO will host the 2024 ASCE Gulf Coast Student Symposium on March 7-11. The event will include the steel bridge, concrete canoe, surveying and sustainability competitions, along with several other competitive civil engineering events.
