Steel Work Complete at Niners New Stadium
Posted by Tasha Weiss on January 31, 2013 at 6:47 PM.
Not only are they playing in the Superbowl this Sunday, the San Francisco 49ers have another reason to celebrate as well: Their new stadium is one step closer to completion.
The final steel beams for the new Santa Clara Stadium were installed last month. During the topping out ceremony more than 570 construction workers joined team management, staff and city officials to celebrate the completion of the project’s steel framework and watched as two gold-painted steel beams were hoisted on top of the frame at the 50-yard line–one with a Christmas tree and other with an American flag. (Click on the thumbnail image to watch a two-minute KTVU.com news segment on the topping out ceremony.)
About 4,000 pieces of steel (equaling about 18,000 tons) were erected to complete the steel framing for the new $1.2 billion stadium. SME Steel Contractors, Inc. (an AISC member) is the steel fabricator and erector for the 1.85-million-sq.-ft project. HNTB and Turner Construction are the project’s architect and general contractor, respectively.
According to the team, the new stadium will also be the first professional sports venue in California to achieve net-zero energy performance. Several types of solar energy will be installed including solar panels on the stadium’s suite tower, three bridges connecting the stadium to the main parking area, and the team’s training center, which is adjacent to the stadium. Other green components include water-efficient plumbing and recycled materials.
Santa Clara Stadium will feature open pedestrian plazas, commercial community space, a 49ers team store and a 49ers Hall of Fame. The stadium is designed to be used for a wide range of events including professional and college football, soccer, motocross, concerts and civic events. It is scheduled to be completed in time for the 2014 NFL season.

Wanted: AISC 2013 Summer Intern
Posted by Tasha Weiss on January 31, 2013 at 10:42 AM.
Do you know an architectural or engineering student looking for an interesting and educational summer internship? Or is that student you?
AISC is now accepting applications from students enrolled in at least the third year of a structural, architectural or civil engineering program. Applicants also must have completed at least one course in structural steel design. The internship is a full-time position at AISC’s headquarters in downtown Chicago and supports the AISC Engineering and Research Department in developing technical resources for structural steel design.
“The summer internship at AISC is a very unique learning experience because of AISC’s broad reach in the structural steel design, fabrication and construction industry,” said Jie Zuo, a former summer intern who now works for AISC as a staff engineer in the Engineering and Research Department.
“AISC is a wealth of information and resources, and it was a great experience to become immersed in different aspects of steel construction,” continued Zuo. “You have the opportunity to see the inner workings of the development of the Steel Specification and contribute to that effort. You get the chance to tour a fabrication shop and see firsthand the processes and procedures required to fabricate steel. Overall, the opportunities that this internship provides are plentiful, and you would not have a similar experience anywhere else.”
Interested students should submit their resumes, including a list of related coursework, by March 1, 2013, to email@example.com with “E&R Summer Internship” in the subject line.
New Online Video Series: HSS Connections
Posted by Tasha Weiss on January 30, 2013 at 5:38 PM.
Atlas Tube (an AISC member), a division of JMC Steel Group, recently premiered its second installment of free “Designing with HSS” online educational videos. The four videos in the new series will cover various topics on hollow structural sections (HSS) connections.
The new series begins with a video titled “Intro to HSS Connections,” presented by Atlas Tube Senior Sales Engineer Brad Fletcher, discussing the various types of connections and challenges involved when designing with hollow structural sections.
“This series provides us an opportunity to really dive into designing with HSS, addressing HSS connection design specifically,” said Fletcher. “The first video series educated engineers and fabricators on HSS design, and now the second series will tackle the more technical side of HSS connections.”
The first video in the new series is now available for online viewing on JMC Steel Group’s YouTube channel (where you’ll also find videos from the first installment) and on Atlas’ blog. The next three videos in the series will be released over the next few months, covering issues ranging from HSS truss connections to HSS product availability.
Reminder: IDEAS2 Award Entries Due By January 31
Posted by Tasha Weiss on January 28, 2013 at 2:40 PM.
Entries are being accepted through this Thursday, January 31, for AISC’s 2013 IDEAS2 Awards. The annual awards program, which has existed for more than seven decades, recognizes outstanding achievements in engineering and architecture on steel-framed building projects around the country.
The awards recognize all members of the project’s team involved with the structural framing system. This year’s winners will be announced at the 2013 NASCC: The Steel Conference in St. Louis, which will be held April 17-19. In addition, awards are presented by AISC to the submitting firms and their fellow project team members at the individual project sites during the summer, and all winning projects will be featured in the May issue of MSC.
Architectural and engineering firms, general contractors, fabricators and owners are encouraged to enter innovative building projects that use wide-flange or hollow structural steel sections for a significant portion of the framing system.

Steel Structure Trivia: Smithsonian Revitalization
Posted by Tasha Weiss on January 25, 2013 at 5:38 PM.
Here’s MSC’s January Steel Structure Trivia question! The Smithsonian Arts and Industries museum on the National Mall in Washington, D.C., is undergoing renovations to the building envelope, including the structural steel framing, roof, windows and masonry facade. Pictured above is a shot of the new steel construction of the roof juxtaposed with the existing steel. Superior Iron Works, Sterling, Va., (an AISC member, AISC certified fabricator and advanced certified erector) is fabricating and erecting the steel for the project. The building will reopen in 2014. Your challenge is to name the year the Smithsonian Arts and Industries museum originally opened. Photo: Jacinda Collins, AISC
The Smithsonian Arts and Industries Museum originally opened in 1881, in time for the inaugural ball of President James A. Garfield. Congratulations to our winner, Robert Smith, P.E., a civil engineer with ATK - ABL Operations in Rocket Center, W.Va.
The Arts and Industries Building is the second-oldest of the Smithsonian museums on the National Mall in Washington, D.C. Initially named the National Museum, it was built to provide the Smithsonian with its first proper facility for public display of its growing collections. It was dedicated a National Historic Landmark in 1971.
In 2006, the building was named as one of America’s Most Endangered Places by the National Trust for Historic Preservation, and the building was closed due to its deteriorating condition. It received funding through the American Recovery and Reinvestment Act of 2009 and has been undergoing structural renovation since 2011.
The building is scheduled to reopen in the summer of 2014 to host programs and exhibitions related to innovation.
The Smithsonian Arts and Industries project, along with the Smithsonian National Museum of Natural History, recently won a 2013 Craftsmanship Award in the Metals category from the Washington Building Congress.

Paul Sullivan, Bridge Engineering Expert, Dies at 86
Posted by Tasha Weiss on January 24, 2013 at 6:15 PM.
Paul James Sullivan, P.E., a retired bridge engineer with the Commonwealth of Massachusetts, passed away on January 10 at Brigham and Women’s Hospital in Boston, surrounded by his family. He was 86 years old.
Sullivan was a lifelong and proud public employee and union member. His career at the Massachusetts Highway Department included instituting and leading the first Quality Control Program for Bridge Erection in the Commonwealth, a program that became a model for other states, and he rose to the position of bridge engineer before his retirement. His contributions to bridge safety were recognized when he became the first public official to receive the American Road & Transportation Builders Association’s prestigious “Lifetime Achievement Award.”
His contributions didn’t stop with his retirement. He devoted many voluntary hours to the American Welding Society towards the development of welding standards and procedures for aluminum and steel. He was a tireless advocate for his fellow workers and became president of the then Local 780 of AFSCME (American Federation of State, County and Municipal Employees).
A strong believer in the value of lifelong learning, Sullivan earned a Bachelors degree and multiple Masters degrees in political science, urban planning and education from the University of Massachusetts - Boston, Boston State College and Rutgers University. He joined the U.S. Marines Corps at 16, served in the South Pacific during World War II and was a lifelong member of the Disabled American Veterans.
He is survived by his wife of 40 years, Toby Pearlstein, a son, a daughter and two grandchildren.

Canam Lands Multiple Steel Projects
Posted by Tasha Weiss on January 21, 2013 at 6:28 PM.
Canam Group, Inc., recently announced that it has added close to $55 million in contracts for various structural steel building and bridge projects.
Structal-Bridges, a division of Canam (and an AISC member/NSBA member/AISC certified fabricator), concluded agreements totaling more than $26 million for the fabrication of two bridges in the U.S.
The first agreement was with the State of Wisconsin to fabricate components for an overpass being built as part of the Memorial Drive Suamico project in Howard. Structal-Bridges will supply 36 box girders for the 2,198-ft structure. Fabrication is slated to begin in March 2013 and deliveries will start in January 2014.
The second agreement was signed with a joint venture, formed by J.F. White and Skanska, to replace the Fore River Bridge that connects the towns of Quincy and Weymouth in Massachusetts. The contract calls for more than 80 girders to construct the bridge and through trusses for the 325-ft vertical lift section. Fabrication will take place between the spring of this year and the spring of 2014. Image: MassDOT
In addition, Structal-Heavy Steel Construction’s expertise in executing complex, large-scale structural steel projects netted the division a number of design-build mandates in the U.S. and Canada, totaling more than $20 million.

Steel Shots: New Gilmerton Bridge Floats In
Posted by Tasha Weiss on January 21, 2013 at 10:51 AM.
A 335-ft-long, 85-ft-wide lift span was floated in and connected to two tower structures last week for the new Gilmerton Bridge in Chesapeake, Va. The new steel lift bridge provides an improved vertical clearance of 35 ft and will see 40% fewer openings each year, easing traffic and marine congestion alike. (Click on the image to see a photo of the completed bridge lift.) Photo: Courtesy of Modjeski and Masters
The $134 million Gilmerton Bridge Replacement project on Military Highway in Chesapeake, Va., provides a new steel lift bridge over the southern branch of the Elizabeth River, replacing the existing double-leaf bascule bridge constructed in 1938. The Virginia Department of Transportation (VDOT) recognized the need to replace the aging bridge to accommodate future growth in an area becoming increasingly congested, and to facilitate better flow of marine traffic.
The replacement project requires the new bridge to be built on the exact same alignment as the existing bridge. Bridge engineering firm Modjeski and Masters designed the new 335-ft-long, 85-ft-wide lift span. Due to the exceptional width, four 15-ft diameter sheaves were needed on each tower structure. Eight 12-ft-diameter drilled shafts were designed to reach 120 ft below ground and are some of the largest ever constructed using the oscillating method. With only 25 ft between the Gilmerton Bridge and an adjacent railroad bridge, seismic instruments were used to monitor potential settlement of the railroad bridge foundations during installation of the new drilled shafts.
Last week the lift span was floated in and connected to two tower structures, and the existing bridge reopened to traffic one week earlier than projected. Mariners will also benefit from the new bridge span due to its enhanced vertical clearance from 11 ft to 35 ft in the closed position and up to 135 ft when the lift span is opened.
Additional work to the Gilmerton Bridge Replacement Project will include the demolition of the existing bridge and construction of the northside approaches, with completion scheduled for early 2014. When the new bridge is complete, it will be 1,908 ft long and 85 ft wide which will increase traffic lanes on Military Highway from four lanes to six.
You can find updates on the Gilmerton Bridge Replacement Project, including a time-lapse video of the float-in, on VDOT’s website at http://virginiadot.org (direct link: http://bit.ly/UW6w65).
