2022 Design and Research Conference

Civil Engineering

Room 124.

1:00 p.m.	Structural designs for the Fabrication Pavilions in Minden, Louisiana Team Members: Alejandro Aristizabal, Kaleb Nolan, Joseph Pellittieri, Ryder Walters Sponsor: Aillet Fenner Jolly McClelland, Inc Advisor: Dr. Amin Azimi The purpose of these two new buildings is to provide shelter from the environment to fabrication and welding processes currently being performed outside. At this time, the owner only wants a roof and partial height walls on the sides with end bays completely open. However, it is expected that the building will be completely enclosed in the future. Design work includes design of foundations, design of slab-on-grade, design of structural steel primary and secondary framing, and design of steel connections.
1:30 p.m.	US 80 and LA 594 Intersection Retrofit with Roundabout Team Members: Joshua Bartley, Jon Hale, Michael Olinde, Brandon Rosalis Sponsor: District 05, State of Louisiana, Department of Transportation and Development Advisor: Dr. Nazimuddin Wasiuddin This intersection was improved with lengthy turn lanes approximately 15 years ago. This project consists of utilizing existing pavement surface and right of way to design a roundabout with curb, gutter, and subsurface drainage. The design work includes traffic data collection; analysis for justification of roundabout, including questions of whether it will operate better than the existing signal, geometric layout, drainage design, sequence of construction, traffic control plans, cost estimate, and cost-benefit ratio; review crash reports; and perform safety analysis to compare safety benefits of roundabout verse signal.
2:00 p.m.	Bridge replacement on LA 534 in Claiborne Parish Team Members: Jacob Hampton, Margaret Kelly, Edward Landry, Jacob Smith Sponsor: District 04, State of Louisiana, Department of Transportation and Development Advisor: Dr. Elizabeth Matthews The bridge designed is located at 32.928042, -93.140024. The proposal is to replace the bridge with a 25-year return period design. The replacement of bridges and other structures is needed due to substandard load carrying capacity or substantial bridge roadway geometry. The bridge piles are decaying and are in major need of replacement. The project design covers reviewing available, geotechnical reports and boring logs, coordinating possible geotechnical investigation and topographic survey, reviewing bridge inspection reports and the Claiborne Parish Flood Insurance Study (FIS), determining watershed boundary and drainage area characteristics, preparing the hydrologic analysis using Louisiana Department of Transportation and Development Hydraulic Manual guidelines, preparing the U.S. Army Corps of Engineers River Analysis System hydraulic analysis for the 10-, 50- and 100-year stormwater flows, evaluating bridge replacement structures and comparing backwater and exit velocities of existing and recommended structures, estimating costs, estimating construction time, and preparing a letter summarizing the study and recommendations.
2:30 p.m.	Asphalt/Pedestrian/Bicycle Trail Team Members: Mathew Alvarez, Jacob Malone, Ann Pozniak, Joel Wells Sponsor: Civil Design Group, LLC Advisor: Mr. Reginald Jeter Designed is a construction of an 8′ wide asphalt pedestrian/bicycle trail from the Red River National Wildlife Refuge Boat Launch to Parkway High School in Bossier City, Louisiana. This project is the extension of an existing trail. Two covered pavilions and parking facilities are designed as well. The length of the trail is approximately 2.25 miles. The owner of the trail is the Red River Waterway Commission. The budget for the trail is approximately $1.5 million.
3:00 p.m.	Highway Embankment Landslide Repairs Team Members: Kody Cameron, Zachary Mayes, Allan Pineda Sponsor: District 05, State of Louisiana, Department of Transportation and Development Advisor: Dr. Shaurav Alam Interstate 20 (I-20) overpass embankments through Ouachita, Richland, and Madison Parishes were constructed of high plasticity index (40+) soil in the mid to late 1960s. Many of these overpasses are experiencing slides and difficulties in maintaining slope stability. The project consists of designing repairs for multiple locations. It includes a selection of design repair options, removal and replacement, chemical treatment of soil, placing Geotech fabric, sheet piles, geofoam blocks, etc., determination of cross-sections – quantities, creating a construction time estimate, and possible traffic control. Repair effectiveness will be compared with the costs of the completed slide project on I-20 in 2015, in which layers of geotextile fabric were used.
