The White House released guidance on the Build America, Buy America (BABA) initiative, an important component within the $1.2 trillion Infrastructure Investment and Jobs Act (IIJA) from 2021. BABA stipulates that certain products must be manufactured in the U.S. to qualify for federal funding in infrastructure projects and emphasizes the use of domestically produced construction materials. As the faucet opens for IIJA projects, make sure your project has certainty and you are building with quality materials you can trust, 100% made in the USA. BABA Highlights: Scope: The BABA guidelines apply to federally funded infrastructure projects, including those under the IIJA. Material Categories: BABA focuses on three primary categories: iron and steel products, manufactured products, and construction materials. Notably, the list has been expanded to include engineered wood but excludes coatings, paint, and bricks based on feedback. Made in America Criteria: To wear the “Made in America” badge, a product must be produced in the U.S., with at least 65% of the cost of its components sourced domestically. This will further increase to 75% in the calendar year 2029. Included Materials: The guidance specifically lists plastic and polymer-based products, non-ferrous materials, glass, fiber-optic cable, engineered wood, drywall and lumber. Implications… Read more »

Geocell Technology Proves Effective in Solving Soil Stabilization Challenges for Solar Farms on Underutilized Lands
With the increasing demand for clean energy, there is a growing interest in repurposing underutilized lands for solar farm developments, particularly abandoned mines, capped landfills, brownfields, and other unused areas. These locations offer a unique opportunity to transform unused spaces into sources of renewable energy, and can be particularly enticing because they are often situated near established transmission infrastructure. This makes the interconnection process simpler and more cost-effective than connecting to remote greenfield sites. In addition to contributing to the shift toward sustainable energy sources, the development of solar farms on underutilized lands can create jobs, generate revenue, and bring new life to areas that have been neglected or forgotten. However, poor soil conditions can pose significant challenges for solar farm developers. To ensure the long-term success of solar projects, factors such as erosion control, stormwater management, and site access must be carefully considered during the design and construction phases, especially when repurposing underutilized lands for solar farm developments where the site conditions may be less than ideal. GEOWEB® Geocells: A Versatile Site Development Solution for Solar Projects Geosynthetics, specifically geocells, can be highly effective in mitigating the challenges posed by poor soil conditions during the development of solar farms….

A Week of Celebration and Inspiration: Engineers Week 2024
“Welcome to the Future!”: Engineers Week 2024 From February 18 to 24, 2024, the engineering community will come together to celebrate Engineers Week. This year’s theme, “Welcome to the Future!”, is a nod to the incredible advancements that have been made and a look forward to the innovations yet to come. It’s a week to celebrate, reflect, and inspire the next generation of engineers. The Roots and Relevance of Engineers Week Initiated in 1951 by the National Society of Professional Engineers (NSPE), Engineers Week has grown into a global celebration. It acknowledges the vital role engineers play in progressing our society. The week aligns with the birthday of one of history’s great engineers, George Washington, who was also a surveyor. This connection underscores the deep roots and enduring impact of engineering in our world. Why “Welcome to the Future!” Matters This year’s theme emphasizes the forward-looking essence of engineering. It’s not just about honoring past achievements; it’s about shaping the future. Engineers are instrumental in developing innovative solutions to some of the world’s most complex challenges, from climate change to advancing technology in renewable energy and communications. This week is an opportunity to showcase how engineering keeps us moving forward,… Read more »
Using Geosynthetics to Stabilize Soils in a Harsh Environment
By Dhani Narejo, PE, Bruno Hay, and Bryan Wedin, PE Mine Site Erosion Problems One of the largest nickel mining sites in the world is located on the South Pacific island of New Caledonia. Due to the size of the mining project and the terrain of the site, significant cut-and-fill work for civil engineering structures was unavoidable. Given the magnitude of the site, the challenge of safeguarding the structures against erosion is formidable. Inaction is not an option due to the sensitive nature of the structures, environmental concerns, and a keen desire by the owners to protect the environment. A typical example of the erosion at the site is the slope in Figure 1. Such slopes require continuous maintenance if the erosion problem is not addressed. In some cases, erosion can cause interruption in the mobility of materials and personnel at the site. Several erosion-control measures had been successfully used at the site, including riprap and concrete. An alternate erosion control system was desired by the owner that would meet the following objectives: Be cost-effective, Require little or no maintenance, Utilize local labor and materials, Have a design life exceeding 50 years. Soil, topography, weather Ultrabasic soils cover about one-third… Read more »
