Thoughts From Engineers: Supreme Court Slices CWA’s Reach
I have never owned property disputed to contain wetlands or had my plans to develop a property blocked because of the presence of wetlands. No doubt, in such a situation I would have felt cheated of important rights, not unlike Michael and Chantell Sackett, plaintiffs in the recently decided Supreme Court of the United States (SCOTUS) case of Sackett v. EPA (May 25, 2023, bit.ly/SackettEPA). The couple received notice of a Clean Water Act (CWA) violation due to the presence of wetlands as they b...
Decrease Concrete’s Carbon: A Big Step in Leaving a Smaller Footprint
Portland-limestone cement provides designers the opportunity to reduce a project’s carbon footprint by up to 10 percent. Concrete is the second-most-used material (after water), which shouldn’t be surprising considering it’s the foundation of nearly all our infrastructure. Engineers and builders specify concrete for their projects because it’s durable, long-lasting, resilient and versatile. Imagine if we could get those characteristics along with an added benefit of being more sustainab...
Safe Passage Across the Sea: Sensors Prevent Overloaded Vehicles Access to Philippines’ Iconic New Bridge
For the tallest and longest bridge in the Philippines, sensors provide for bridge protection based on accurate measurement of vehicle axle loads. (Kistler Group) The Philippines, a southeast Asian island state officially comprising 7,641 islands and home to more than 115 million people, is on the rise. Wealth is growing thanks to dynamic economic development in the vibrant Asia-Pacific region; tourism is booming, and increasing numbers of infrastructure projects aim to bridge the gap (liter...
Sustainable Stormwater Solutions: Embracing Low-Impact Development (LID) for Enhanced Stormwater Quantity and Quality Control
In 2017, heavy rains from Hurricane Harvey flooded the greater Houston area, prompting local officials to reassess their stormwater-management systems. In recent years, climate change has affected Earth’s weather patterns, which have turned unpredictable and often dangerous. Rising temperatures are accompanied by a higher risk of intensified flooding, as heat domes and cold fronts collide, creating more extreme rain events. As a result, stormwater runoff becomes more severe, leadi...
Creating Certainty: Expanded Shale, Clay and Slate Aggregates Improve Seismic Design
Lightweight aggregate helps address seismic concerns on a highway project. (Acrosa Lightweight) The ground a structure is built on plays an important role in what’s possible for that project—soil’s stability and relative depth to the bedrock can determine a structure’s height, footprint and weight limitations. It also can help a building better-resist seismic activity. The soil around a structure can change seismic waves’ frequency content and amplitude; these soil-structure inter...
