Hello NSPE Members and Guests! Please join us for this month's in-person and virtual luncheon.
Controlled low-strength material (CLSM) is low-strength concrete (between 50 to 150 psi) used as a cost-effective alternative to compacted natural soil. Industry and inspectors use different methods for compressive strength testing, resulting in widely varying strengths. When CLSM is outside of its low-strength range, it must be torn out, resulting in time and cost delays in construction. The "C" Spot evaluates three moulding methods (masonry block, grout box, and split cylinder), three capping methods (gypsum, sulfur, and neoprene), and studies the behavior of CLSM with relation to depth to evaluate the performance of current testing methods.
Justin de Leon is a Civil Engineering major at the University of Nevada, Las Vegas, and Project Associate at Perlman Architects. Justin is the past President of UNLV's Institute of Transportation Engineers (ITE) chapter and was responsible for rechartering the chapter after 10 years of inactivity. His previous internship experiences were at D.R. Horton and Toll Brothers, where he has developed a passion for home building and construction.
Megan Taylor Agbayani is a Civil Engineering major at the University of Nevada, Las Vegas. Megan's past internship experience was at Kimley-Horn and Associates, and she is planning on joining their Solar team this fall as a Civil Analyst in their Las Vegas office. She is looking forward to playing an important role in many renewable energy projects across the country. During her free time, she is an avid reader, singer, and traveler.
The objective of this senior design project was to redesign West Alexander Road between Rancho Drive and Decatur Boulevard into a roadway that is safer for its nearly 6,000 daily road users, uniform between urban and rural sections, and functional for all modes of travel. The project scope included research of existing conditions and prior market solutions, alternative evaluations, and a final design with a proposed cost and schedule. The final proposed design is a complete street design that includes uniform vehicular lanes, sidewalks, bike lanes, and equestrian paths. The design also includes traffic-calming measures such as a lateral shift and raised medians, drainage infrastructure to reduce flooding during storm events, and roundabouts at the two major intersections to reduce travel speeds and minimize crash risks. The implementation of this final complete street design would transform West Alexander Road into a safe, accessible, and sustainable roadway.
Gustavo Mendez: Gustavo is a fresh graduate from UNLV with a Bachelor's degree in Civil Engineering. During his time as a student, he has gained a diverse experience through internships in the fields of surveying, structural engineering, materials testing, and residential land development. Gustavo will be transitioning from an internship to a full time position at Westwood Professional Services in Las Vegas.
Bryan Oxborrow: After graduating from UNLV with a BS in Architecture, Bryan furthered his education of the built environment and recently obtained a BS in Civil Engineering. During his studies, Bryan has had the opportunity to progress his career in engineering and has gained experience in commercial land development, surveying, utility coordination, and structural engineering. He now works as a full time project manager and overseas projects in the telecommunications sector managing drawing production from conception to completion.
Hannah Singleton: Hannah is a new UNLV graduate with a BS in Civil Engineering. She spent time in her undergraduate career interning with the Southern Nevada Water Authority where she found her passion of working in the water/wastewater industry. Hannah also performed undergraduate research studying the effects of thermal shock on the compressive strength of mortar, and she worked as a peer mentor in the UNLV College of Engineering. Hannah looks forward to starting her engineering career this summer and beginning a master's degree in Civil and Environmental Engineering beginning this fall.
