Low Impact Development for More Sustainable Solutions: Pervious Concrete
Low impact development (LID) embraces land development practices that mimic pre-existing hydrologic processes. A brief introduction to some LID techniques will be provided followed by details of successful installations of pervious concrete for various applications.
Central Texas Flood & Lessons Learned: San Antonio District
Analysis of the July 4th, 2025, flood event in Central Texas.
A Fancy Pile of Rocks: A Framework for Holistic Thinking about Pavement for Non-Technical Owners and New Engineers
Pavement structural strength is a sum of its various parts, not all of which are easily understood. As with all civil engineering, the structure is only as good as the weakest component, not least of which is the ground it stands on. Because ‘natural ground’ upon which structures are founded is described in geotechnical reports […]
Transforming a High-Risk River Crossing into Design Certainty: Geotechnical Investigation for the US-51 Ohio River Bridge
A comprehensive overwater geotechnical investigation was performed to support replacement of the US 51 Ohio River Bridge between Wickliffe, Kentucky, and Cairo, Illinois. Prior investigations were constrained by complex subsurface conditions, challenging river environment, and platform limitations, resulting in uncertainty for deep foundation design. This study presents an integrated approach to acquiring high-quality subsurface data […]
Rethinking Underground Detention: Design Flexibility, Cost Savings & Constructability with Precast Concrete Systems
Urban development continues to push the limits of conventional stormwater management due to space constraints, evolving regulations, and increasing infrastructure demands. In response,modular precast concrete systems are emerging as a resilient and efficient solution—offering design flexibility, accelerated timelines, and long-term durability. This presentation will explore how modular precast detention systems address critical challenges related to […]
From Demolition Waste to FAA-Compliant Base Course: Materials Management at DFW Airport
Large airport capital programs generate substantial volumes of demolition debris and surplus excavation material, creating ongoing challenges related to disposal costs, material procurement, hauling logistics, and schedule risk. At Dallas Fort Worth International Airport (DFW), the scale and pace of concurrent airfield and landside construction required a more coordinated, program-level approach to managing construction materials. […]
High-PI Stabilization for Concrete Pavement Performance
Concrete pavements are widely recognized for their structural capacity and long service life; however, long-term performance is fundamentally dependent on uniform and stable foundation support. Expansive, highly plastic clays (PI ≥ 35) contribute to differential movement, moisture-driven distress, and reduced pavement reliability, underscoring the importance of effective subgrade stabilization in resilient pavement systems. This presentation […]
Beyond Strength: Integrating Resilience into Civil Infrastructure Design
Civil infrastructure is increasingly exposed to extreme weather, climate variability, aging systems, and growing urban demands. Traditional design approaches that focus primarily on strength and safety are no longer sufficient to address these emerging challenges. This session explores how resilience can be integrated into civil infrastructure design to improve system performance under uncertain conditions. The […]
From Vision to Reality: Delivering Multimodal Projects Through Integrated Planning and Engineering: Connecting Statewide Strategy, Project Portfolio Development, and District Delivery to Advance Transportation Solutions
Moderator: Ram Maddali As transportation agencies work to address growing mobility needs, infrastructure demands, system resiliency, and funding constraints, successful project delivery requires strong coordination between planning, programming, engineering, and implementation. Transforming long-range transportation goals into projects that can be funded, developed, and delivered demands an integrated approach that bridges organizational, technical, and geographic boundaries. […]
Long-Term Geotechnical Liabilities Caused by Elevated Groundwater Levels After Construction
Geotechnical reports by all engineers always include groundwater conditions existing at the time of the site and investigation. The reports also indicate the probability of groundwater fluctuation at the time of construction. However, most reports don’t identify the risk of serious structural issues that can develop after construction due to sustained elevated groundwater levels over […]
