Florida Flyover Lift Completed within a Day
Posted by Tasha Weiss on July 16, 2012 at 5:07 PM.

A five-million-lb. flyover ramp was lifted yesterday to accommodate new roadway construction on Interstate 595 near Fort Lauderdale, Fla. The curved steel tub girder bridge that connects southbound University Drive to eastbound I-595 was raised 18 in. within a 24-hour period.

 

Synchronized hydraulic jacks slowly raised the bridge, and a team of about 50 construction workers inserted 18 shims that hold up the flyover, according to an article published in The Miami Herald. The south part of the ramp will be removed in order to make room for more lanes that will widen I-595.

 

The article states the original plan was to remove both flyover ramps that connect University Drive and I-595. Raising the ramp was the alternative that helped save time–and taxpayer dollars–by keeping one whole bridge and using half of the one being lifted.

 

University Drive and I-595 closed beginning at 11:30 p.m. on Saturday and reopened by today’s morning rush hour, with the exception of the flyover ramp on southbound University.

Bridge engineering firm Modjeski and Masters announced last week that it has been selected by the National Radio Astronomy Observatory (NRAO) for the fifth consecutive structural inspection of West Virginia’s Robert C. Byrd Green Bank Telescope. Modjeski and Masters will audit the 17-million-lb movable radio telescope as part of an ongoing effort to prolong the structure’s life span through periodic assessments and programmed maintenance.

 

Modjeski and Masters will conduct a comprehensive inspection of many of the structure’s more than 13,000 steel members and joints. The firm will leverage its Technical and Rope Access (TARA) program, which is a collection of techniques and methods of access used by highly trained engineers to safely gain access to remote points on the structure. (Some can be located as far as 480 ft above the ground.)

 

“Modjeski and Masters works with a level of professionalism, thoroughness, reliability and competence rarely seen these days,” said Harry Morton, technical support supervisor at the National Radio Astronomy Observatory. “We cannot inspect the entire structure ourselves, but can rest assured that the telescope is sound because of the trustworthiness of the Modjeski and Masters team.”

 

Dedicated in 2000, the Green Bank Telescope is the most technically advanced single-dish radio telescope in the world. The 110-meter by 100-meter dish boasts more than two acres of area for collecting faint radio waves from the universe.

Alamo Iron Works Acquires SGS Industrial Supplies
Posted by Tasha Weiss on July 11, 2012 at 3:58 PM.

Alamo Iron Works, a San Antonio-based steel fabrication company and an AISC member, announced recently that it has bought the assets of SGS Industrial Supplies, Inc., a distributor of steel and industrial products in the Rio Grande Valley area of South Texas.

 

Two years after Industrial Distribution Group (IDG) bought Alamo Iron Works, the 137-year-old company will expand its distribution network in South Texas by combining its operations with SGS. Alamo Iron Works is no stranger to the Rio Grande Valley, having served customers in the area for more than 80 years, frequently crossing paths with previous competitor SGS, which has been active in the market for 60 years.

 

The combined company will provide increased field sales support, unmatched inventory levels and a comprehensive catalogue of industrial supply and steel products and services.

 

“This opportunity allows us to enhance our historical position in the Rio Grande Valley while maintaining and expanding the valuable relationships nurtured by SGS,” said Alamo Iron Works President F.M. “Duffy” Shea. “We are in a position of strength thanks to the investment and commitment of our parent company, Industrial Distribution Group, which has allowed us to successfully grow the business and take advantage of timely opportunities.”

 

IDG Lead Board Director Scott Prince added, “SGS has an excellent reputation for serving customers throughout the Rio Grande Valley. Existing Alamo Iron Works customers now have access to two new locations in ‘The Valley,’ while SGS customers have access to an expanded number of products and steel services that were not available to them before this combination.”

 

Together the companies are extending their joint commitment to the local community by continuing full operation of both SGS distribution centers in Pharr and Brownsville, Texas.

student-photo-2012_small.jpgKnow a college student who’s looking for a fun summer challenge? Have them grab their camera and start snapping! In conjunction with this year’s SteelDay, AISC is again sponsoring a Student Photo Contest as a way to involve students in the structural steel industry’s largest educational and networking event.

 

The photo contest is designed for students to capture photos that best pictorially celebrate the visual experience of steel, and is open to any student currently enrolled in a graduate or undergraduate program at an accredited U.S. college or university.

 

To be eligible, students must submit a photograph and a completed application form, including a brief description of the photograph. The description can include information such as details regarding the photo subject, interesting elements in the photo and/or how the photo celebrates the visual experience of steel. There is no fee to enter and the number of complete submissions per student is unlimited.

 

Entries are due by Saturday, September 22, and the winners will be announced on SteelDay (Friday, September 28; check back here for a news post after SteelDay). One grand prize winner will receive a digital photo frame and be published in an upcoming issue of MSC. All winning submissions will be featured on modernsteel.com as our weekly “Steel Shots,” which are published each Friday.

college-of-new-jersey-4_sitn_thumbnail.jpgStudents and faculty in the engineering program at The College of New Jersey, along with ASCE’s local chapter, this past spring celebrated the installation and dedication of an AISC sculpture on the school’s campus in Ewing Township, N.J.

 

The sculpture helps distinguish Armstrong Hall as the campus’ engineering building to students and visitors alike. And, beyond its enhancements to the program and school, the sculpture ultimately serves as a learning tool for civil engineering students as it provides examples of beams and connections studied in class.

 

“We are very excited to have one of these sculptures because it is a tremendous highlight to our program and to the hard work of all the students,” said Catherine Brabston, student chapter president of ASCE at The College of New Jersey. “In addition, our professors look forward to the opportunity to use it as an educational tool in structural and steel design courses.”

 

The students involved in the installation experienced the complete process behind it, from testing the soil to the design and fabrication of the steel sculpture, to the foundation design and final assembly. And all students can gain from this sculpture an appreciation for structures and the engineering behind them.

 

The fabrication, galvanizing and delivery of the sculpture was donated by Capital Steel Service in Trenton, N.J., an AISC member and AISC certified fabricator. General contractor Waters & Bugbee, also based in Trenton, donated the foundation, including material and installation costs, as well as the final installation of the sculpture.

 

Originally created by Duane Ellifritt, professor emeritus from the University of Florida, the AISC Steel Sculpture was designed to be a visual teaching aid that shows a variety of members and connections. It consists of 25 steel members, 43 connection elements, more than 26 weld groups, and more than 144 individual bolts.

 

These sculptures are located on more than 100 campuses across the U.S., and most have been donated by local fabricators.

 

To see if a school near you has a steel sculpture, see the list in the Faculty and Students section of the AISC website.

 

To find out how to get a Steel Sculpture on your campus, please email Maria Mnookin at universityprograms@aisc.org. Fabricators interested in building and donating a steel sculpture to a university should also contact Maria.

 

To see more of the sculptures at various schools, visit the AISC Education Flickr page or the American Institute of Steel Construction Facebook album.
