Achieving Net Zero by 2050: $139 Trillion Sustainable Infrastructure Investment Needed
Under current governmental decarbonization policies, global sustainable infrastructure investment is estimated to remain at around US$2t per year, with cumulative investment between 2020 and 2050 totaling around US$75t. This is a significant investment but still insufficient to achieve net zero. In fact, it is only just over half of the actual investment required. Our analysis — conducted with the International Federation of Consulting Engineers (FIDIC) — shows that, cumulatively, US$139t needs...
Decarbonizing Infrastructure: Why Data, Collaboration and PAS 2080 Are Critical to Success
In the UK, construction activity accounts for around 50m tonnes of CO2 emissions , with cement and steel used for infrastructure being significant contributors. For the UK to meet its statutory climate targets, a whole lifecycle approach must be adopted to ensure the design, execution and ope...
Music City Makeover: New Equalization Facility Helps Nashville Wrestle with Water Overflows
Long-time residents of Nashville still reel when remembering the flooding that occurred during the weekend of May 1-2, 2010, when 13.57 inches of rain was measured in a 36-hour period. The two-day rainfall total doubled the previous 48-hour rainfall record, and the human and financial consequences proved devastating. The storm killed 11 people in the Nashville area, including one victim whose body was found nearly five months after the flood. Nearly 11,000 properties were damaged or destroyed...
Building for the Future: Sustainable and Resilient Designs with Lower-Carbon Concrete
(Image Credit: Portland Cement Association) Florida’s unique environmental challenges, including its vulnerability to hurricanes, rising sea levels and extreme weather, highlight the need for sustainable and resilient building designs. As coastal urbanization grows and climate concerns escalate, there’s increasing pressure on architects and developers to implement materials and methods that ensure long-term durability while reducing environmental impact. Concrete, especially when spe...
From the Editor: Resilience: A Journey Through Climates and Time
I just reread Maria Lehman’s excellent column in the 2024 Sustainable Engineering Issue of Informed Infrastructure, “Engineers Must Share Their Infrastructure Stories.” It’s full of facts and data about our needs, but what I found most interesting is how it stresses our role in passing on the infrastructure message to whoever we can, whenever we can. I tell my students—senior civil and environmental engineers—that they’re moving into the workforce at a great time to provide work on projects tha...
Transportation Troubleshooting: Modular Construction at Airports: Three Key Considerations for Time-Saving Options
As airports grow and modernize to meet consumer expectations and accommodate technological advances, they face the challenge of maximizing their ability to make improvements while minimizing the impact a major construction program will have on customers and day-to-day operations. Since comprehensive airport-improvement projects require years of construction, it’s critical to avoid costly shutdowns, disruptions and delays for airlines and passengers whenever possible. For some airports, that sol...
Thoughts From Engineers: Investigating Biodiversity and Resilience
Extreme weather events such as the 2018-2020 drought in central Europe, the 2022 heat wave and drought in the wider European region, and other record-breaking events across the planet are becoming common. The International Panel on Climate Change issued statements in recent years regarding the effect such weather and climate-driven events have had on ecosystems, rates of species decline and biodiversity across the globe. Some in the scientific community suspect that the more biodiverse an ecosys...
Executive Corner: Gen X Takes Over the C-Suite, With a Little Help From the Millennials
In 2024, the youngest of the Baby Boomers will turn 60, and by the end of the decade, all members of this generation will exceed age 65 (the average retirement age in the United States). The A/E and environmental-consulting sector has been in the midst of ownership transition between the Boomers and their younger counterparts for the last decade or more. However, the transition of C-suite leadership from the Boomers to Gen X and the Millennials is a more-recent development and presents its own c...
Water Works: Realize the Benefits of Nationally Recognized MTD Performance-Verification Protocols
In a previous professional capacity, I managed a post-construction stormwater management program for a relatively small locality. It was a fulfilling role, although perhaps not outwardly glamorous. It was a “one-man-band” situation—I joke that the only thing I didn’t have to do was serve as the animal control officer. Resources were tight, time was valuable and prioritizing tasks became necessary. Redundancy was to be avoided, unless I was filling out triplicate forms for any expenditure. This...
Change Leader: Leading a Grassroots Movement for Greater Engineering Diversity
This interview was recorded by Todd Danielson, the editorial director of Informed Infrastructure. You can watch a video of the full interview above or by visiting bit.ly/3ASyxvv. Frances Yarbrough is a civil engineer and director of the SeamonWhiteside (SW+) Charlotte office. It’s striking to realize the current percentage of females in the field of engineering, at about 17 percent, is a dramatic rise over the last few decades. But progress is still progress, and engineers s...
