Nucor Breaks Ground for New Mill
Posted by Tasha Weiss on March 17, 2011 at 8:53 AM.
Nucor Corporation has broken ground on a new direct reduced iron (DRI) making facility in St. James Parish, La., between Baton Rouge and New Orleans. The company received its air permit from the Louisiana Department of Environmental Quality in January, enabling it to move forward with construction.
The company initially will build one DRI plant, expected to create 150 permanent jobs, but it has been permitted for the construction and operation of two plants with a combined annual DRI production of 5.5 million tons.
Direct reduction technology converts natural gas and iron ore pellets into high quality direct reduced iron used along with recycled scrap to produce numerous high quality steel products such as sheet, plate and special bar quality steel. The DRI facility is the first phase of a multi-phase plan that may include a coke plant, blast furnace, pellet plant and steel mill.

ACSA Acknowledges AISC’s Decade of Support
Posted by Tasha Weiss on March 16, 2011 at 8:54 AM.
Since the inception of ACSA’s Steel Design Student Competition 10 years ago, AISC has provided continued sponsorship support of the competition. In recognition of this partnership, ACSA presented AISC with an award at its 99th Annual Meeting held March 3-6 in Montreal.
The Steel Design Student Competition challenges students, working individually or in teams, to explore a variety of design issues and create innovations related to the use of steel in design and construction. Last year, about 450 students from 75 schools of architecture entered the competition, challenged to design “a retreat from real world diseases, promote healing, and foster a reconnection at the individual and collective levels.” You can view the winners on AISC’s web site here. (scroll down on the page)
The 11th annual competition is now under way, with a Homeless Assistance Center as this year’s structured challenge. (There is also an “open” category.) Winners for the 2010-2011 academic year will be announced in July. Read more about the program on ACSA’s web site here.
In Memory of Harry Fogle: Bridge Pioneer
Posted by Tasha Weiss on March 15, 2011 at 8:57 AM.
Harry Fogle, a remarkable bridge pioneer who was one of the last surviving workers on both the Golden Gate Bridge and the San Francisco Bay Bridge, died of natural causes on February 18 at the age of 97.
A bridge painter and foreman for more than 40 years who was a survivor of an era when men worked without nets high above the San Francisco Bay, the National Steel Bridge Alliance featured his lustrous career in its September 2010 newsletter.

Steel Shots: Lawrence Encourages His Team

Ernest Orlando Lawrence (standing, back to camera), was considered the father of “Team Science” and a consummate leader of cross-disciplinary scientific projects. Here he addresses colleagues in a late 1930s photo near the 184-in. cyclotron construction site. Photo: Lawrence Berkeley Nat’l Lab.
The Lawrence Berkeley National Laboratory in Berkeley, Calif., is one of 17 U.S. Department of Energy national labs. Today its more than 4,200 employees carry on research in world-class facilities constructed over the last eight decades on the 200-acre campus.
“Berkeley Lab was founded in 1931 by Ernest Orlando Lawrence, a UC Berkeley physicist who won the 1939 Nobel Prize in physics for his invention of the cyclotron, a circular particle accelerator that opened the door to high-energy physics. It was Lawrence’s belief that scientific research is best done through teams of individuals with different fields of expertise, working together. His teamwork concept is a Berkeley Lab legacy that continues today.” (From http://www.lbl.gov/LBL-PID/LBL-Overview.
Lawrence’s cyclotron started small, but then grew to an 11-in. diameter, then 27-in., and they continued to get larger as scientists tried to reach higher energy levels. The lab’s 184-in. cyclotron was housed in the round building in the photo, shown as the steel framing was being erected. To learn more about the development of the cyclotron, click here. (At the end of that page is a 1941 photo of the completed building.)

Steel Shots: Steel in the High Desert

Two years after building his first steel house on 2 1/2 acres of high desert in Yucca Valley, Calif., David McAdam with Blue Sky Homes, Palm Springs, Calif., is building a second sustainable steel-framed home similar to its prototype. Like its predecessor, the new home is a hybrid, using a prefab frame made of factory-cut, light-gauge steel that is bolted together on site, but still allows for lots of customization and a hip, midcentury modern feel, according to an article in The Desert Sun.
Setting the home’s foundation on a 10-acre parcel of rocky terrain posed some design challenges, but its steel pillars allow Blue Sky to build on sloped or uneven terrain with minimal grading. According to the article, the 1,250-sq.-ft house is planned to be assembled and ready for move-in within eight weeks.
Going with steel also gave the home a green solution. “The new house is 70% recycled, and the whole structure will be 15% to 20% more energy efficient than California’s rigorous green building standards,” said McAdam and Palm Springs architect Lance O’Donnell, who designed both the Blue Sky homes.
