Open BIM Collaboration Gains Momentum in AEC Industry
Posted by Tasha Weiss on March 14, 2012 at 2:15 PM.
BuildingSMART International along with several leading software companies have partnered together to launch the Open BIM program, a universal approach to help promote open standards and workflows for improved collaboration in the design and construction of building projects. The program is based on buildingSMART’s Industry Foundation Classes (IFC), an open and neutral data exchange format that covers multiple disciplines across the construction industry.
The Open BIM approach offers key benefits to building project stakeholders:
- Workflow integration results in greatly reduced coordination errors compared to sheer file exchange-based coordination of the different disciplines.
- Project members can work with the best-of-breed solutions in their respective fields without risking “incompatibility” hence exclusion from certain BIM projects.
- Project members can maintain full control over software upgrades independently from their peers on the different AEC projects they participate in.
- Accessibility of BIM data is provided for the entire life cycle of buildings including design, construction and operation.
Learn more about the Open BIM program at www.openbim.com.
AISC supports the Open BIM program and for more than a decade has been at the forefront of advancing BIM collaboration through open standards in the structural steel industry. Recently, AISC developed a new three-step interoperability strategy to evaluate data exchanges and integrate structural steel information into buildingSMART’s IFC, which you can read about in AISC’s press release at http://bit.ly/qnifZr.
Also, in the March issue of MSC, AISC’s Chris Moor and Luke Faulkner take an in-depth look into the how and why behind the steel construction industry’s migration to IFC. You can view and download the article at http://bit.ly/wy52wD.

Virtual attendees can attend up to 10 of the sessions and also receive up to 13 professional development hours. (Registration for the virtual conference is $250 for AISC members and $400 for non-members.) For more information about the NASCC virtual conference, visit www.aisc.org/2012live.
If you are planning to be in Dallas for the conference, keep in mind that if you haven’t made your hotel arrangements yet, March 25 is the deadline to book your hotel room at the Gaylord Texan Hotel & Convention Center, the official NASCC hotel. After that date the room blocks will be released, and reservations will be based on availability and higher rates will be charged. Reserve a hotel room and plan your trip at www.aisc.org/nascc.
Walter P Moore Receives ACEC Engineering Excellence Award
Posted by Tasha Weiss on March 12, 2012 at 2:50 PM.
Water P Moore is one of the winners of this year’s American Council of Engineering Companies’ (ACEC) Engineering Excellence Awards. The firm was recognized for its structural design of the KFC Yum! Center in Louisville, Ky.
An innovative foundation and structural system enabled the 22,000-seat multi-purpose arena to rise from an unstable, flood-prone site congested with massive underground structures, tunnels and pits. One of building’s most notable and striking elements is its 406-ft-long structural steel roof truss featuring an 11,000-sq.-ft “waterfall,” a three-story glass facade supported by curved architecturally-exposed steel tubes.
Nearly 3,000 tons of steel total was used for the KFC Yum! Center, which opened in October 2010. More information about the arena, including photos and videos, can be found at www.arenaauthority.com.
All 25 winners will be recognized at ACEC’s Engineering Excellence Awards Gala, April 17, 2012 in Washington, D.C.
Steel Shots: Restoring One of America’s Great Machines

After talks of retiring one of the great machines of American industry, The Fifty, when it broke down three years ago, Alcoa has redesigned the massive Mesta Press at the company’s Cleveland Ironworks. A recent article by Tim Heffernan, published in The Atlantic, describes the story of this 92-ft structure—with five stories above and seven below ground—which began production in 1955 and is scheduled to resume service early this year.
Heffernan says that what sets The Fifty apart from the average forging press is its extraordinary scale. The machine weighs 16 million lbs and is made up of 14 major structural components, all cast in ductile iron, that weigh as much as 250 tons each. (Its yard-thick steel bolts are 78 ft long!) When activated, The Fifty’s eight main hydraulic cylinders deliver up to 50,000 tons of compressive force, which Heffernan compares to bench-pressing the battleship USS Iowa, with 860 tons to spare.
It is with this power, combined with amazing precision, that gives The Fifty its far-reaching utility. The press was originally installed as part of the Air Force Heavy Press program following World War II, and since then has made essential metal parts for industrial gas turbines, helicopters and aircraft. Every manned U.S. military aircraft now flying uses parts forged by The Fifty, as does every commercial aircraft made by Airbus and Boeing.

2011 High Performance Building Awards Winners Announced
Posted by Tasha Weiss on March 7, 2012 at 5:35 PM.
The National Institute of Building Sciences’ Sustainable Buildings Industry Council (SBIC) recently announced the recipients of its 2011 Beyond Green High Performance Building Awards. The awards recognize initiatives that shape, inform and catalyze the high-performance building market, as well as the real-world application of high-performance construction practices. The program consists of three award categories: High Performance Buildings, High Performance Initiatives and High Performance Products.
Two steel projects achieved Honor Awards in the High Performance Buildings category:
The Redding School of Arts in northern California took First Place for a New Academic Complex. With an emphasis on the performing arts, the 77,000-sq.-ft public charter school, which features exposed steel framing, has been designed with a balance of traditional design elements and innovative technology concepts. The school’s mission the school is to use LEED Platinum certification as a starting point, and it has a building “dashboard” that will show how well it is actually performing.

The second steel-framed winner, the U.S. Port of Entry in Calais, Maine, was awarded First Place for New Construction. Energy-efficient design and the reuse of materials were important components of the project, making it one of the nation’s first LEED Gold ports. Located on the eastern-most land port of entry into the U.S. from Canada, the facility consists of one 80,000-sq.-ft building separated into two different operational building sections, and is part of a larger infrastructure project that enhances the flow of transportation between the two countries while improving security for customs and border protection.

Steel Shots: Higher Education
Posted by Tasha Weiss on March 2, 2012 at 12:21 PM.
The complicated vertical stack of Roosevelt University’s new 32-story “vertical quad,” along with the building’s undulating facades, results in no two floors being alike and is a showcase for the versatility of steel framing. The photo shows two-story deep outrigger trusses connecting to built-up box columns, which increases the lateral stiffness of the concrete core and maintains accelerations in the tower’s residential levels within recommended limits.

In 2007, Roosevelt University, an independent non-profit institute in the Chicago metropolitan area, faced a dilemma regarding the future of its main downtown campus. The City of Chicago had just instituted new code provisions requiring that all high-rise buildings, new or old, be fully sprinklered, and the university’s 17-story residential and student life building, the Herman Crown Center, did not meet this criteria. Because the university’s downtown campus revolved around the Center and the adjacent world-renowned, historic Auditorium Building, a tough decision had to be made on whether to renovate the existing building or abandon it and start anew.
After evaluating the costs of upgrading the existing building and considering future growth projections, the university’s board of trustees approved a plan to demolish the Herman Crown Center and build a new, modern structure that addressed the university’s specific requirements.
However, while the new building would contain all of the amenities and features of a modern university, there was one critical element missing: land area. By the nature of its downtown location and small 16,000-sq.-ft lot, the entire program would need to exist in a vertical configuration rather than a traditional horizontal campus layout. The concept of a university quad would literally need to be turned on its side.
With this in mind the project team developed a striking 32-story building that cleverly meets all programming requirements in one vertical stack. To handle this complete stack of building uses, structural steel was ultimately selected for its ability to provide column-free spaces at the classrooms and laboratories, allow future flexibility as the University’s needs change and accommodate the project’s required framing complexities.
When completed this month, the new tower will form an exciting addition to Roosevelt University’s growing downtown campus and the Chicago skyline. As a true “vertical university,” the project provides an excellent model for other universities with similar space constraints.
You can read more about the Roosevelt University project in the March issue of MSC, available now.
