AISC’s Moor to Chair NBIMS-US V3 Project Committee
Posted by Tasha Weiss on August 16, 2012 at 5:36 PM.

chrismoor_new_300.jpgChris Moor, AISC director of industry initiatives, has been selected as the new chair of the project committee tasked with developing Version 3 (V3) of the National BIM Standard for the United States (NBIMS-US).

 

A project of the National Institute of Building Sciences buildingSMART alliance (bSa), NBIMS-US is a consensus document that serves to standardize the way practitioners use BIM to more easily pass information from one phase of the building process to another. The NBIMS-US Project Committee oversees the standard’s development.

 

“I enthusiastically support the Nominating Committee’s selection,” commented AISC Chair William B. (Brad) Bourne III of Universal Steel, Inc., Lithonia, Ga. “They could not have chosen a more knowledgeable, energetic and experienced leader than Chris Moor, to lead the development of their vision for NBIMS-US V3. We wish Chris the best of luck and stand behind him with all that AISC can offer.”

 

Moor has been a long-time advocate for open standards and improving interoperability. He has worked with 3D technology and BIM since 1994 and leads AISC’s efforts on technology integration and interoperability, which include exploring, implementing and promoting new technologies that support and enhance the entire structural steel supply chain. AISC is committed to maintaining the structural steel industry’s leadership in interoperability and ensuring data related to structural steel can be exchanged throughout the supply chain and with other disciplines and trades. (Learn more at www.aisc.org/integration.)

 

“Involvement in bSa and NBIMS-US is an investment in the future of the whole construction industry,” said Moor. “I am looking forward to the challenge ahead, and am proud and humbled to be a part of the NBIMS-US effort.”

 

A member of the NBIMS-US Project Committee and a director on the buildingSMART alliance Board of Direction, Moor was heavily involved in the development of NBIMS-US Version 2. He is also a member of the Design-Build Institute of America BIM Committee; co-chair of the American Iron and Steel Institute BIM Committee; secretary of AISC’s Technology Integration Committee; member of the Level of Development Special Interest Working Group (an Associated General Contractors of America/BIMForum/American Institute of Architects effort); and serves as the AISC lead for a Fiatech project addressing interoperability for steel within the process industry. Prior to his tenure at AISC, he was the managing director of Tekla Corporation’s UK subsidiary.

 

The NBIMS-US Project Committee will next elect a vice chair and secretary and will call for committee members to join the various working committees and subgroups to develop V3. Individuals and organizational representatives can participate on the committee, but first they must become members of the National Institute of Building Sciences and its buildingSMART alliance.

Vermont’s largest truss bridge, the 350-ft-long Checkered House Bridge on Route 2 in Richmond, was widened in just a day and a half earlier this month. The design-build rehabilitation and widening of the bridge, which was built in 1929, is the first time such a technique has been tried on a bridge of this scale.

 

After months of preparation, the historic bridge was literally rolled out 12 feet six inches to the north, achieving a launching rate of two feet per hour.

 

The Checkered House Bridge project is only the second design-build project undertaken by the Vermont Agency of Transportation (VTrans) since design-build project delivery was authorized by the Vermont legislature. They retained Finley Engineering Group, Inc., Harrison & Burrowes Bridge Constructors, Inc., and CHA, Inc., to widen the bridge.

 

“Widening a bridge of this age, type and size was technically challenging because we needed to consider construction engineering during the design phase,” said Jerry M. Pfuntner, P.E., Finley project manager.

 

Finley developed and implemented the concept to widen the bridge by cutting and moving the entire North truss chord in place. To maintain the bridge’s historical integrity, the plan was to widen the bridge leaving as many of the original steel members as possible, and installing new structural bracing members within the widened portion of the bridge only. To accomplish this, Finley developed the original concept for a falsework and jacking system that allowed the North truss to be moved while still receiving lateral support from the South truss system.

 

The South truss was designed to support the entire existing truss bracing members with the aid of this unique falsework system that stabilized the eccentric self-weight, wind loading and jacking forces through the many phases of the North truss jacking operation. Finley designed the hydraulic side-launching jacking system that assisted with separation of the truss members from the existing connections, moved the North truss and facilitated fit-up of the new bracing members, and provided a means to adjust the camber of the North truss.

 

The bridge is scheduled to be completed in late spring 2013. For more information about the project and additional photos of the bridge widening, visit Finley’s website at www.finleyengineeringgroup.com (direct link: http://bit.ly/Qmcr0R).

BIM at the Olympics
Posted by Tasha Weiss on August 9, 2012 at 4:33 PM.

Bentley Systems, Inc., has commended its software users for their contributions to London’s built environment for the 2012 Olympic and Paralympic Games. The company says London residents and visitors are benefiting from Bentley users’ recent work leveraging BIM for the creation and operation of the city’s infrastructure including skyscrapers, office complexes, transportation systems and sports venues.

 

BIM empowers designers, builders and owner-operators to simulate the performance of an asset before it’s built, assuring it will be constructed and performed according to design intent. To achieve the required quality, performance and value-add in designing and constructing sports venues in London, while also meeting tight deadlines, Bentley users employed Bentley Systems’ BIM software to take full advantage of information mobility across project phases and disciplines.

 

Examples of these users and their respective venue work (which are all steel structures) at Olympic Park include:

  • Arup – Aquatics Centre, Handball Arena 
  • Buro Happold – Olympic Stadium
  • Edge Structures – Aquatics Centre
  • Hopkins Architects – Velodrome
  • Make Architects – Handball Arena
  • Populous – Olympic Stadium
  • Wilkinson Eyre – Basketball Arena

“Come Steel with Me”
Posted by Tasha Weiss on August 6, 2012 at 12:58 PM.

Does steel make you want to break into song? It did for Klaudia Siczek.

 

steel-musical-video-copy.jpgInspired by her steel design course in 2008 at the University of Illinois at Urbana-Champaign (taught by Abbas Aminmansour), Siczek decided to create a music video. Titled “Come Steel with Me,” the video shows her appreciation for steel design and whisks you away into its education with lyrics such as “We can take our wide-flanges, and calculate Sx, Ho and J!”

 

Whether or not you’re a structural designer, you’ll appreciate this video. Watch it now at http://youtu.be/ruDX_tt8GPY.

Steel Shots: Olympic Bridge
Posted by Tasha Weiss on August 3, 2012 at 10:32 AM.

Newly constructed for this summer’s Olympic and Paralympic Games, the 137-ft-long, 18-ft-wide, all-steel Bridge Lo1 in London’s new Olympic Park serves as a vital link for pedestrians heading to and from the Northern Spectator Transport Mall. Photo: Atkins

 

Built on a Brownfield site ripe for rehabilitation, the new Olympic Park on London’s northeast side is sporting a whole new infrastructure this summer. Millions of visitors are expected between last weekend and early September for the London 2012 Olympic and Paralympic Games, and 23 new bridges are among the facilities helping them make their way into and around Olympic Park. One particularly interesting and unusual bridge, known as Lo1 or the Ruckholt Road Bridge, combines the mechanics of a tied arch with Vierendeel girder construction to provide a highly efficient structure with a light and airy look.

 

Bridge L01 is the primary northern gateway to the Olympic Park. Elegant in both appearance and concept, it provides a pedestrian and cycling link from parking in the Northern Spectator Transport Mall, which also is a key access point for coaches, taxis and disabled visitors.

 

The design architect, London-based Allies and Morrison, and structural engineer Atkins, also based in London, used a sophisticated iterative design process to create a highly efficient structure with slender arch members.

 

installation-of-bridge_sitn.jpgConstruction of the bridge began in May of 2010 and was completed this past March. The 137-ft-long, 18-ft-wide steel structure was fabricated in Wales. Shipped in several pieces, it was welded together on-site prior to being lifted into place. One of Europe’s largest cranes was brought in for the lift, which occurred in November 2010. (Click on the photo for an enlarged view. Photo: Atkins)

 

You can read more about the Bridge Lo1 project in the August issue of MSC (available now!), in the “What’s Cool in Steel” section. In this section you’ll also find another cool Olympic steel structure: The ArcelorMittal Orbit, which was featured in last month’s Steel Structure Trivia post on our website, here.

Steel Design Student Competition Winners Announced
Posted by Tasha Weiss on August 2, 2012 at 2:50 PM.

Twenty-one architecture students from universities across the U.S. were honored in the 12th annual Steel Design Student Competition for the 2011-2012 academic year. Administered by the Association of Collegiate Schools of Architecture (ACSA) and sponsored by AISC, the program challenges architecture students, working individually or in teams, to explore a variety of design issues related to the use of steel in design and construction.

 

This year’s Category I competition, entitled Culinary Arts College, challenged students to design steel-framed facilities with at least one long-span steel structure. Required spaces included teaching kitchens, a pastry kitchen, classrooms and a demonstration laboratory.  

 

the-paris-market-lab_sitn-copy.jpgDavid Heck from California Polytechnic State University won first place for designing “The Paris Market Lab.” (Click on the image for an enlarged view.)

 

“Steel was a wonderful facilitator of what I had envisioned for this adaptive reuse project,” said Heck. “In some places, I wanted the steel to provide the project with bold gestures that would be able to stand alone, aesthetically, from the existing conditions. Other places, the steel intervention was more subtle, so as not to drawn attention from some of the existing conditions, but rather make them more vivid by the presence of the steel and glass addition. Steel was the only structural material versatile enough to do both.”

 

Jonathan Reich was his faculty sponsor and called the award “a wonderful reward for all of David’s talent, effort and sustained attention to his fine project.”

 

Category II was the open submission design option and permitted the greatest amount of flexibility. Top kansas-city-soccer-training-center_sitn-copy.jpghonors in this category went to Dan DeWeese from the University of Kansas for his “Kansas City Soccer Training Center,” which allowed him to focus a portion of his architectural education on his interest in sports training and rehabilitation. “The hexagon, derived from many images of the sport, is emphasized to develop this identity for both the project and the competition,” he commented. (Click on the image for an enlarged view.)

 

His faculty sponsor was Kent Spreckelmeyer, who said, “His concept of a steel structural and enclosure system derived from a hexagonal geometry was a central part of his design from the beginning, and was critical in organizing and explaining his solution.”
