The new Cowboys Stadium in Dallas has received the 2009 Outstanding Civil Engineering Achievement Award, presented by The Texas Section of the American Society of Civil Engineers (ASCE). The award was presented on April 12 in Austin, Texas.
The project also will be honored at the upcoming 2010 NASCC: The Steel Conference, May 12-15 in Orlando, Fla., where the project team will receive the President’s Award of Excellence in Engineering as part of AISC’s Innovative Design in Engineering and Architecture with Structural Steel (IDEAS2) program.
AISC member firm WALTER P MOORE served as lead structural engineer for the project. The $1.15 billion, 80,000-seat, three million sq. ft, retractable roof superstructure established at least three structural engineering world records. It is the longest single-span roof structure in the world; it boasts the world’s largest center-hung HD video display board; and its operable glass doors are the world’s largest. Additionally, the roof’s mechanization system is the first application of a rack-and-pinion retractable roof drive system in North America and the largest and steepest such roof application in the world.

Global Design Factory has created the perfect writing instrument for engineers and architects to look the part. How perfect: While drafting a building one can be writing with a variety of recycled construction materials, including steel. Intrigued? Check out the company’s catalog at http://bit.ly/cMdb1G.
Both the pens and pencils can be engraved to include your company name.
Student Survey on Steel Estimating Software
Posted by Tom Klemens on April 28, 2010 at 2:29 PM.
If you have a couple of minutes to give back to the industry, a group of students at the University of Illinois - Chicago would appreciate your input. The students are conducting market research on the Steel Estimating Software industry. Their purpose is to create and distribute a software program that will make the bidding process more efficient.
The online survey includes 24 questions, many of which require just yes/no answers, on five simple screens. To begin the survey (which will open a new window), click here.
Editor’s note: Although no deadline was provided, remember that the end of the academic year is drawing near, so don’t put it off.

Welding Consumables Catalog, Consolidated and Online
Posted by Tom Klemens on April 27, 2010 at 3:14 PM.
Lincoln Electric has introduced its first ever “Consumable Product Catalog.” It includes Lincoln Electric’s full line of legacy welding consumables, as well as new products introduced over the last year to help customers increase productivity and improve weld quality.
Similar to the “2010 Equipment Catalog,” the new Consumable catalog will have an online Fast-Flip eBook version that is accessible on Lincoln’s website. The searchable online catalog features intuitive, book-like navigation, making Lincoln’s entire product line more easily accessible and product selection easy.
The new catalog will replace the existing individual consumable family catalogs that are separated by process or brand to make it easier to find what you are looking for in one place.
This catalog includes in-depth information on the company’s full line of welding consumables, including product features and applications, conformances, AWS requirements, test results, and typical operating procedures. In addition, it has diagrams, images and dimensions for all packaging options available as well as a summarized welding equipment section.
To access the online version of the Consumable Catalog, visit www.lincolnelectric.com.

The Steel Joist Institute (SJI) has released a new 13-minute video that provides an extensive overview of open web steel joists. In addition to covering the benefits of steel joists (strength-to-weight ratio, flexible and adaptable design, durability and economic advantages), it also offers a summary of the various steel joist products including the bar joist or short-span K-Series, long-span and deep long-span LH/DLH-Series, CJ-Series and steel Joist Girders.
View the video online by way of the SJI website by clicking here.
Copies on DVD also are available for purchase on the SJI website, www.steeljoist.org.
Steel Shots: An Irish Image
Posted by Tom Klemens on April 23, 2010 at 2:45 PM.
Looking much like an Irish harp lying on its back, the Samuel Beckett Bridge in Dublin, Ireland, opened on December 10, 2009. The cable-stayed steel box girder bridge spans 120 m (394 ft) from quay to quay; the top of the arching steel pylon is 48 m (157 ft) above the high water level of the River Liffey. Named for the Nobel Prize-winning Irish writer, the bridge was delivered by barge as an essentially complete structure.
The Samuel Beckett Bridge, whose Irish (or Gaeilge) name is Droichead Samuel Beckett, is the second bridge in Dublin designed by architect Santiago Calatrava. (The first, which opened in 2003, is the James Joyce Bridge, further up the River Liffey.) The entire 5,700-tonne (6,300-ton) structure was fabricated beginning in 2007 in Rotterdam, the Netherlands, by Hollandia. The 120-m bridge made the seven-day journey on a 90-m by 26-m barge, arriving in Dublin on May 11, 2009.
The cable-stay anchorages run down the center of the bridge separating its two northbound and two southbound traffic lanes. Wide footpaths and cyclepaths are included on both sides to accommodate Dublin’s significant volume of non-vehicular traffic.
The entire structure is supported on one pier located out of the main navigation channel. It can rotate 90 degrees on that pier to allow the passage of taller vessels. Total cost of the bridge was 60 million euros ($82.3 million).
Additional information about and images of the Samuel Beckett Bridge are available on the Dublin City Council website.

Click here to view a short video file compiled from still photos taken May 13, 2009. It shows the bridge on the barge as it passed the raised East Link Bridge, making its way up the River Liffey, plus photos of the surrounding area. (Beware that it opens by showing the statues at the Famine Memorial on the Custom House Quay).
Happy Earth Day!

The Art Institute of Chicago has gone green. The new Modern Wing, completed last May, used recycled steel and other local materials which helped the structure to obtain silver LEED certification. To find out more about the Modern Wing view the video that is embedded at the bottom of the Art Institute of Chicago website.
