Steel Work Complete for Haiti Health Center
Posted by Tasha Weiss on February 19, 2014 at 6:34 PM.
The new Gheskio Family Health & Nutrition Center in Port-au-Prince, Haiti, has reached a significant project milestone: The steel frame is complete. It was erected by Haitian workers together with a small American crew.
Designed by NYC-based firm Tonetti Associates Architects, the new health center represents GHESKIO’s comprehensive approach to nutrition, clinical care and community development through combining various healthcare and family planning departments within a single complex.
The design team undertook this project as an opportunity to help the people of Haiti after the devastation they experienced in the Haiti earthquake.
“We chose a steel frame building because of the lower mass of the building as compared to the standard Haitian concrete and masonry construction, and because of the great control of the detailing of the structure,” said Andrew Wright, AIA, LEED AP, of Tonetti Associates Architects.
Construction is expected to be complete this fall.
A August 2011 MSC article entitled “Assurance of Quality” discusses the project team’s choice of steel for the health center, written by Charles J. Carter, S.E., P.E., Ph.D., AISC vice president and chief structural engineer.

Engineers Week Kicks Off
Posted by Tasha Weiss on February 17, 2014 at 5:12 PM.
National Engineers Week commenced yesterday and runs through Saturday, February 22, with various educational and celebratory events that provide interactive experiences with engineering.
For example, the Chicago Architecture Foundation (CAF) kicked off its slate of week-long events yesterday with an all-day festival called “Engineers This! Building That!” designed to help families discover what engineers do by providing educational presentations, demonstrations and hands-on activities emphasizing engineering related to buildings and structures.
Hundreds of children, students and adults attended throughout the day and were able to meet engineering professionals from around the region, including volunteers from the Structural Engineers Association of Illinois (SEAOI), and learn about the work they do to shape our cities, as well as participate in various activities which included: constructing skyscrapers using LEGOs and testing them in a simulated earthquake (as shown in the top-left photo); discovering the building materials of structures (including steel!) and innovative systems like shear walls and how they resist earthquake and wind forces; and designing their very own bridges (as shown in the photo at right).
Other events offered by CAF this week include a tour tomorrow of the steel-framed Willis Tower to explore the unique architecture and structural design of this famous Chicago building, an adults-only LEGO skyscraper competition (judged by SOM’s Bill Baker) with cocktails on Wednesday hosted by the Architects from the Council for Tall Buildings and Urban Habitat, and an engineering day for teens on Saturday at Crown Hall, where they’ll be able to engage in structural design challenges with practicing architects, engineers and other designers.
Now in its 63rd year, National Engineers Week is organized by DiscoverE (formerly the National Engineers Week Foundation) whose mission is to help unite, mobilize and support the engineering and technology volunteer communities.

Whether you’re single or attached, it’s hard not to love Times Square’s heart-shaped, red and pink architectural sculpture, called “Match-Maker,” designed to cosmically connect people this Valentine’s Day–and supported by structural steel.
Designed by Young Projects, a Brooklyn-based multidisciplinary design firm, Match-Maker was chosen as the winner of this year’s annual Times Square Valentine Heart Design by Times Square Arts and Van Alen Institute. It was unveiled on February 10 and will remain on view for one month at Father Duffy Square, between 46th and 47th Streets.
This interactive installation is made of powder coated aluminum tubes. Each tube is a custom piece, varying in length, angle and color. The aluminum periscopes are each suspended by a series of powder coated brackets that attach to a single steel column.
Visitors arrange themselves at twelve points around the heart-shaped sculpture. Peering through colorful, interwoven periscopes provides glimpses of each viewer’s four most ideal astrological mates, offering potentially novel connections between lonely souls or settled lovers. The form of the sculpture is elusive, complex and symmetrical, and changes as viewers experience it from different vantage points throughout Times Square. From many points of view it forms a perfect and iconic heart; from other perspectives the sculpture is tangled and perplexing.
For the past six years, the Times Square Alliance has invited architecture and design firms to submit proposals for a romantic public art installation celebrating Valentine’s Day in Times Square.

Construction Industry Pledges to Hire 100,000 Veterans
Posted by Tasha Weiss on February 13, 2014 at 10:53 AM.
In an announcement on Monday at A National Symposium: Veterans’ Employment in Construction, hosted by the U.S. Department of Labor and Joining Forces, First Lady Michelle Obama and U.S. Secretary of Labor Thomas E. Perez celebrated a broad coalition of construction employers and associations that have collectively pledged to hire 100,000 veterans over the next five years.
Also at the event were representatives of the construction companies making these hiring commitments, veterans who have completed apprenticeships in the construction industry and other leaders in the field.
The construction industry is expected to grow rapidly in the coming years, outpacing the steady growth of the economy as a whole and helping to strengthen local communities. The Bureau of Labor Statistics estimates that construction is one of the fastest-growing industries in the nation, with job growth of more than 1.5 million jobs between now and 2022 – an annual growth rate of 2.6%.
More than 80 companies across the country, large and small, are committing their existing training and employment programs to fill new construction jobs with veterans, and executives from several participating companies were present at the event. One of them, Larry L. Melton, a project executive for Bechtel and Marine Corps veteran, said, “Veterans are invaluable to the construction industry. Men and women who serve in the military often have the traits that are so critical to our success: agility, discipline, integrity, and the drive to get the job done right,” said Melton.
Lori Sundberg, senior vice president of human resources at Jacobs, said, “We are pleased to support programs that provide career opportunities for our military veterans. Many of the skills and abilities gained during military training and service are highly transferable to the skills we require to successfully serve our clients around the world.”
Following the announcement, the department’s Veterans’ Employment and Training Service and Employment and Training Administration hosted the Symposium’s three roundtable discussions, which included information on how to access veterans’ employment services that are available at more than 2,600 American Jobs Centers across the country.
Remarks from the event were live-streamed for the public and you can watch the video recording at the U.S. Department of Labor’s YouTube channel (www.youtube.com/user/USDepartmentofLabor).
Stan Musial Veterans Memorial Bridge Opens
Posted by Tasha Weiss on February 11, 2014 at 6:03 PM.
The new Stan Musial Veterans Memorial Bridge made its public debut on Saturday, with various celebratory events and a ribbon-cutting ceremony, and opened to traffic on Sunday.
The 1,500-ft cable-stayed bridge connects Illinois with Missouri over the Mississippi River near downtown St. Louis and is the third longest bridge of its kind in the U.S. The photo at left shows the towers on the Missouri and Illinois sides of the new bridge lit up at night.

The $230-million bridge was built to alleviate traffic on the nearby Poplar Street Bridge, which carries Interstates 55, 64 and 70 as well as U.S. 40, and runs between downtown St. Louis and East St. Louis, Ill. I-70 traffic has been rerouted to the new bridge, which accommodates two lanes in each direction, with the ability to expand to three lanes. Construction on the project started in February 2010.
HNTB Corporation, the bridge’s structural engineer, created a design that employed steel anchor boxes inside of the pylons for the stay cable anchorages instead of using formed concrete corbels. The use of steel anchor boxes eliminated the need for complex forming of concrete inside the bridge’s delta-shaped pylon legs. Ultimately, the use of steel saved time, reduced cost, increased accuracy in the tight tolerances of the cable geometry and reduced the amount of post-tensioning needed around the perimeter of the pylon legs.
The project uses 8,000 tons of structural steel in all, which was fabricated by W&W/AFCO Steel (an AISC/NSBA member and AISC Certified fabricator). Tensor Engineering (an AISC/NSBA member) was the project’s steel detailer.
“The Stan Musial Veterans Memorial Bridge is a significant and iconic addition to this nation’s infrastructure and to the skyline of St. Louis, and W&W/AFCO Steel takes great pride in witnessing its grand opening,” said Deane Wallace, senior vice president at AFCO Steel. “We appreciate the cooperation of the HNTB design team in helping translate their vision to workable solutions; Massman, Traylor, Alberici, a Joint Venture, planned and labored five years to build this massive structure, and we congratulate them on the success of their great efforts; AFCO Steel spent two years fabricating 8,000 tons of steel to form the strong and elegant backbone of the bridge; MoDOT and ILDOT bring this iconic bridge to the public and we expect them to take great pride in their new Steel Centurion for the next 100 years. The ‘Stan Span’ is truly a ‘Grand Slam!’”
The new bridge got its name from a compromise between politicians on both sides of the Mississippi River, who had different ideas for the name of the bridge. The Missouri side wanted to name the bridge after the St. Louis Cardinals’ legendary outfielder and first baseman Stan Musial, who died last year, and the Illinois side wished to honor military veterans. In the end both sides won, and this past summer the bridge was officially named the Stan Musial Veterans Memorial Bridge (SMVMB). Photo at left: Tim Parker Photography, courtesy of HNTB

Government officials from both Illinois and Missouri came together to celebrate the completion of the new bridge during a ribbon-cutting ceremony on Saturday.

Late last year, Nucor-Yamato Steel’s (NYS) mill in Blytheville, Ark., (an AISC member) reached a significant milestone: a quarter-century of operation.
Since opening in 1988, it has produced an estimated 48 million tons of structural steel - all of it via the electric arc furnace (EAF) process. The short version is that the mill makes new steel products out of old steel products, melting down scrap and casting it into new wide-flange and other shapes. The long version is much more interesting…
You can take an inside look at this modern, high-tech steelmaking operation in the February 2014 issue of Modern Steel Construction (available now!). Read the article by Modern Steel’s Senior Editor, Geoff Weisenberger.
New Book Explores Chicago River Bridges
Posted by Tasha Weiss on February 6, 2014 at 5:52 PM.
A new book entitled Chicago River Bridges, by Patrick McBriarty, presents the evolution and history of Chicago as the “Drawbridge Capital of the World.” This comprehensive guidebook chronicles more than 175 bridges spanning 55 locations along the Main Channel, South Branch and North Branch of the Chicago River.
Throughout, McBriarty delivers new research into the bridges’ architectural designs, engineering innovations and their impact on Chicagoans’ daily lives. Describing the structure and mechanics of various kinds of movable bridges (including vertical-lift, Scherzer rolling lift and Strauss heel trunnion mechanisms), he explains how the dominance of the “Chicago-style” bascule drawbridge (which is made of steel) influenced the style and mechanics of bridges worldwide.
If you’ll be in Chicago, McBriarty will be providing a Book Launch & Talk on Tuesday, February 18, at 6 p.m. in the Cindy Pritzker Auditorium (lower level) of the Harold Washington Public Library (400 S. State Street). He’ll be giving a multimedia presentation on Chicago’s bridges and the innovation, design and major contributions to moveable bridge technology by Chicagoans. A book signing will begin at 7 p.m. after the presentation.
