NYC “Skywalker” Population Dwindles
Posted by Tasha Weiss on April 30, 2012 at 2:18 PM.
Did you know that some of the country’s most iconic steel structures, including the Empire State Building and the original World Trade Center, were built by generations of Mohawk tribe ironworkers (also known as “Indian Skywalkers”)?
According to a NPR story, aired earier this month, for the past century a small Indian reserve in Kahnawake, Quebec (near Montreal) has supplied the U.S. with a proud lineage of Mohawk ironworkers. But with fewer Mohawks going into the trade, the tradition may be on the wane.
At the peak, in the 1950s, there were as many as 800 Mohawks living in New York City; many were likely drawn to the high-rise ironworker trade for its pay and benefits, according to the article. Today, however, there are only about 200 Mohawk ironworkers building NYC skyscrapers.
Mike Delisle, the grand chief of Kahnawake, says one reason for the decline is that young tribal workers are taking more jobs in the thriving tobacco industry on the reserve rather than choosing to apprentice as ironworkers. He hopes more of the tribe will return to the trade that helped build not only the New York City skyline, but also the tribe’s own town in Canada.
You can listen to the full audio news story, as well as read the print version, on NPR’s website, www.npr.org (direct link: http://n.pr/JlS8N3). The article also includes a link to a three-minute video that profiles a Mohawk ironworker, Kaniehtakeron “Geggs” Martin, who’s been climbing steel for 15 years.
Steel Structure Trivia: Span on the Strait
Posted by Tasha Weiss on April 27, 2012 at 10:01 AM.
Here’s MSC’s April Steel Structure Trivia question! This detailed photo shows one of the intricate steel supports for a 4,200-ft-long icon. Can you name this steel structure? Photo: Larry Flynn
Answer: This steel structure is the famous Golden Gate Bridge in San Francisco! (The photo was taken from South Vista Point — if you click on the thumbnail, in the bottom left corner you’ll see the arched steel trusses that support the structure — you can also see the lighthouse at Fort Point) Congratulations to Jon Gerlach of Infrastructure/Design 1 in New York, N.Y.; Kris White of United Performance Metals in Hamilton, Ohio; and Anantha Chittur of Baldridge and Associates, Inc., in Palatine, Ill., for being the first three people to submit the correct answer! And thank you to all who participated.
The Golden Gate Bridge, one of the world’s longest suspension bridges, spans the Golden Gate strait (its total length is 8,981 ft - about 1.7 miles!), which connects the San Francisco Bay to the Pacific Ocean. Declared one of the modern “Wonders of the World” by ASCE, the bridge was completed in 1937 and today provides passage to nearly 107,000 users a day.
At 4,200 ft long, and with a vertical clearance of 220 ft at mid-span, the Golden Gate Bridge suspension span was considered the longest in the world for 27 years until New York City’s Verrazano Narrows bridge took that title in 1964. The Golden Gate Bridge’s main towers, suspended structure, anchorages and approaches account for the 83,000 tons of structural steel used on the project.
The Golden Gate Bridge’s 75th anniversary is coming up this May 27th! If you live in the area and haven’t yet made plans for Memorial Day weekend — which is also when nearly 600 students will converge at Clemson University, S.C., to compete in the ASCE/AISC National Student Steel Bridge Competition (NSSBC) — consider joining the anniversary celebration at the Golden Gate Festival, open to the public. You can also check out other Golden Gate Bridge tribute and anniversary events happening throughout the month of May at www.goldengatebridge75.org.
The Golden Gate Bridge received an NSBA Prize Bridge Award in 1937, and was also named an “Industry Choice” winner in NSBA’s special “America’s Favorite Bridges” competition last year. You can read a description about the bridge, and the other selected favorites in the U.S., in the November 2011 issue of MSC (direct link to the article: http://bit.ly/Ieljr2).
You can test your steel structure knowledge right here on our MSC website on the last Friday of each month, where a new photo showing only a detailed portion of a steel structure will be posted to the Steel in the News section as our weekly “Steel Shot.” Your challenge is to correctly answer the trivia question provided in the news post, based on what you see in the photo. The next question will be posted at 10 a.m. (CDT) on Friday, May 25.
The first three people who supply the correct answer will receive a MSC-branded stainless steel back scratcher! You’ll need it to successfully tackle those pesky itches after the trivia pressure subsides. (And check out that telescoping action! Wow!) Its five-fingered curved design reaches from 7 in. to 20 3/4 in. in length.

Steel Shots: Open Learning
Posted by Tasha Weiss on April 13, 2012 at 4:18 PM.
The New Children’s Museum in San Diego offers a unique learning environment for kids and families–including its infrastructure. The building’s exposed structural materials and open spaces foster creativity and education while providing a great lesson on how architectural and structural elements work together in harmony. (Click on the photo to see an outside view of the project.) Photo: Geoff Weisenberger
The school year is almost over, but learning continues at the New Children’s Museum, located in San Diego’s Marina District.
Designed by architect Rob Wellington Quigley, the museum is a three-level, 50,000-sq.-ft series of transparent, flexible spaces that visibly expose the building’s construction and design–inspiring children and families to think, play, and create.
Opened in May 2008, the building contains expansive galleries, open studio environments, and an Arts Education Center that offers various classes and camps. It features interactive art exhibitions such as 33-ft-high wooden Trojan horse sculpture, which visitors can actually go into.
The facility is also one of the first green museums in California. The structure uses environmentally sustainable architecture and construction practices, including recycled building materials, a passive air-handling system, photovoltaic panels, water-saving devices, daylighting and convection cooling.
A few blocks from the building is a park and playground that extends the museum’s exposed structural materials to the outdoors. The open steel structure features swing sets and various laser-cut messages in the roof.
(Check out the laser-cutting precision of one of the roof messages from a creative viewpoint!)
