The 12 steel-framed projects recognized in the 2014 IDEAS² awards ranged from a 140-foot-diameter library dome to a courthouse and a nanotechnology center. The roundup is a historical account, not a current ranking: AISC reported that the projects were selected from nearly 100 submissions for structural engineering, architectural impact and construction innovation.
The awards were grouped into three categories by total constructed value, with a separate Presidential Award of Excellence in Engineering. The projects below show how steel served different purposes—from spanning a gorge to shaping a double-curved roof. Details and figures are as reported in the 2014 award article; they have not been independently updated.

What did the 2014 IDEAS² awards recognize?
AISC’s annual Innovative Design in Engineering and Architecture with Structural Steel (IDEAS²) awards recognized engineering and architectural achievements in steel-framed building projects in the United States. The 2014 article says a panel of design and construction professionals selected National and Merit awards across three bands of total constructed value: less than $15 million, $15 million to $75 million, and more than $75 million. One World Trade Center received a separate Presidential Award of Excellence in Engineering.
The selection criteria went beyond the presence of steel in a building. They included creative responses to program requirements; innovation in connections, gravity systems, lateral-load-resisting systems, fire protection and blast protection; aesthetic and visual impact; architecturally exposed steel; technical or architectural advances in steel use; and innovative design and construction methods. The projects therefore represent different kinds of achievement, rather than entries in a single standardized performance contest.

- Ergonomically Designed: Work in tight areas with a compact design that gets into tough spots
- Both tools are designed to fit into difficult to reach spaces
- Complete a wide range of applications with a high-performance motor that delivers up to 300 UWO, and an impact driver delivering up to 1,400 in-lbs of torque
- Both the DEWALT impact driver and drill driver feature integrated LED work lights with a convenient 20-second delay, ensuring enhanced visibility in dimly lit or challenging work areas
- One-Handed Loading - Keep one hand free with a 1/4 in. hex chuck that accepts 1 in. bit tips
That distinction matters when comparing them. A long-span truss, a damped frame and an exposed diagrid address different structural and architectural conditions. The article offers project descriptions, not uniform measures that would establish one building as technically superior to another.
Which projects won in the over-$75-million category?
The highest construction-value band included four projects: one National Award winner and three Merit Award winners. The article highlights a shaped steel roof, a building designed around post-earthquake operation, a specialized research facility and a courthouse with a seismic design strategy.

Newport Beach Civic Center and Park — National Award
In Newport Beach, California, the civic center’s wave-shaped roof was made by bending W10 sections into a double-curved form using multiple radii. The example brings structure and visual expression together: the steel members are not simply hidden supports beneath a conventional roof profile; their geometry helps create the roof’s defining shape. The article identifies the project as the National Award recipient in this value category.
Salt Lake City Public Safety Building — Merit Award
The 172,000-square-foot public safety facility in Salt Lake City was designed for continued operation after the maximum credible earthquake described in the article. Its selected structural system was a steel moment frame with viscous dampers, which the article compares to shock absorbers. This is a different design emphasis from the civic center roof: here the reported innovation concerns the building’s seismic response and intended post-event function.
The 2014 article also described a Net Zero Energy goal and a planned LEED Platinum rating. Those are historical statements about the project’s goal and plan, not verification of its present-day energy performance or certification. The article’s wording should not be read as proof of current operating results.

Krishna P. Singh Center for Nanotechnology — Merit Award
The University of Pennsylvania’s Krishna P. Singh Center for Nanotechnology in Philadelphia was another Merit Award recipient. The article names the university as owner and WEISS/MANFREDI as architect, and identifies the building as a nanotechnology center. Its inclusion shows that the awards covered research and institutional buildings as well as public facilities. The source does not provide a specific structural system for this project, so its award should not be taken as evidence for any particular steel detail beyond its place among the recognized steel-framed projects.

The San Diego courthouse annex was reported as 463,700 square feet with 14 courtrooms. Its steel eccentrically braced frame (EBF) was designed using performance-based criteria to address the project’s seismic and other constraints. An EBF is the structural system named in the source; the article’s summary does not supply enough information to infer specific performance targets or outcomes beyond that design approach.
Which projects won in the $15-million-to-$75-million category?
This middle value band paired an exposed, coordinated federal office building with a glass-and-steel urban pavilion, a campus addition spanning a gorge and an art museum whose sloping form required close model coordination.
U.S. Army Corps of Engineers Federal Center South Building 1202 — National Award
In Seattle, the 209,000-square-foot Federal Center South Building 1202 used an exposed steel structure and a perimeter diagrid. The project’s design coordination extended across structural, mechanical, lighting and acoustical disciplines, making integration part of the achievement described in the article. Rather than treating steel as an isolated frame, the project had to reconcile the visible structure with other building systems.
The article also reports that the project stayed within its original $68 million design and construction budget. That is a historical cost statement from the 2014 article, not a current estimate or a like-for-like cost comparison with the other award recipients.

Brookfield Place Entry Pavilion — Merit Award
The New York pavilion used glass and steel to connect an underground pedestrian passageway to Brookfield Place and the Hudson River. Its role is both spatial and connective: it links a below-ground route to the waterfront destination above. The article does not specify a structural system or dimensions for the pavilion, so its significance here is the described combination of steel, glass and circulation.
Onondaga Community College Ferrante Hall Academic II Addition — Merit Award
The 45,000-square-foot addition in Syracuse, New York, spans a gorge and connects campus facilities. Its primary long-span solution comprised three two-story trusses, each spanning 200 feet. To erect the structure, the construction team used a temporary support tower in the gorge and staged the work. The description makes clear that the design problem involved not only carrying the finished building across the gap but also sequencing erection in a difficult location.
Eli and Edythe Broad Art Museum — Merit Award
At Michigan State University in East Lansing, the Broad Art Museum’s frame used non-parallel sloping walls, wide-flange members and castellated beams. Hollow structural section (HSS) tube frames were used in the stairs, and HSS members also served as window mullions. The museum illustrates how structural framing and architectural geometry can interact: sloping, non-parallel walls create coordination demands that differ from those of a regular grid.
The article particularly emphasizes coordination between digital design and shop-drawing models. When a building’s geometry is irregular, alignment between design information and fabrication documentation is important to translating the intended form into built steel. The source identifies that coordination as part of the project’s story, without claiming that digital models eliminate all construction risk.
Which projects won in the under-$15-million category?
The lowest construction-value band included a public library dome, an education and curriculum-production center, and a pedestrian link connecting two buildings. Their forms and uses differ, but each illustrates a distinct way a steel structure can address a project-specific requirement.

San Diego Main Public Library Dome — National Award
The San Diego Main Public Library Dome was described as a 140-foot-diameter, post-tensioned steel-leaved dome. Its large circular span makes it the roundup’s clearest example of steel used to define a major roof form. The article’s description supplies the diameter and structural characterization; it does not give further engineering data such as loads, material quantities or measured performance.
Battle Creek Area Mathematics and Science Center — Merit Award
The Battle Creek, Michigan, center was described as serving two linked purposes: high-school education and the production and distribution of science curriculum materials. Its place among the Merit Award projects broadens the list beyond civic, cultural and research buildings. The article does not identify a specific steel system for the center, so the reliable takeaway is its program and award status rather than an undocumented structural feature.
United Therapeutics Pedestrian Connector — Merit Award
Completed in 2012 in Silver Spring, Maryland, the United Therapeutics connector spans more than 90 feet across a street and joins two buildings at the sixth floor. It was developed as a truss, with the walking path inside the exposed structural members. This arrangement makes the crossing itself part of the architectural experience while linking the buildings at an elevated level. The source provides the span as more than 90 feet, not an exact measurement.

One World Trade Center in New York received the Presidential Award of Excellence in Engineering, separate from the three construction-value categories. The article describes its structural system as a hybrid: a reinforced-concrete core combined with a perimeter ductile steel moment frame.
That combination is distinct from the project examples organized around a single highlighted steel element, such as the dome or trusses. In One World Trade Center, the award article points to the relationship between a concrete core and a steel perimeter frame as the defining structural arrangement. The award classification should not be confused with a fourth cost band.

What do the 12 projects show about structural steel?
Taken together, the projects show that “steel building” does not describe one structural solution. Steel appeared in a double-curved civic roof, a moment frame with viscous dampers, an eccentrically braced courthouse frame, a perimeter diagrid, long-span campus trusses, sloping museum framing, a post-tensioned dome and an exposed pedestrian truss. The article also includes projects for which its brief description does not name a particular steel system.
The examples likewise cover different design pressures. Some address shape and visual impact; others span an obstruction, connect separated destinations, coordinate structure with building services, or respond to seismic design requirements. Award criteria explicitly encompassed both technical matters—such as gravity and lateral systems—and architectural qualities, including exposed steel and visual impact. The roundup’s breadth reflects that combined focus.
These are the projects and descriptions reported in 2014, chosen from nearly 100 submissions, not a current ranking of structural steel buildings. The article is useful for understanding what AISC recognized in that award year, but it is not a substitute for current project records, certification verification or engineering guidance.
Frequently Asked Questions
What does IDEAS² stand for?
The acronym expands to Innovative Design in Engineering and Architecture with Structural Steel. It names AISC’s awards program for engineering and architectural achievements in steel-framed building projects.
Does a project receiving an IDEAS² award mean steel was its only structural material?
No. One World Trade Center, for example, was described as a hybrid of a reinforced-concrete core and a perimeter steel moment frame. The award recognized steel-related achievement, not necessarily an all-steel building.
Can I use these award descriptions to choose a structural system for a new building?
Not on their own. The roundup gives brief case descriptions, not design calculations, site conditions, code analysis or project-specific engineering advice; a licensed design team must evaluate those factors for a real project.
Are all 12 buildings National Award winners?
No. The 2014 article distinguishes National and Merit awards within the three construction-value categories, and lists One World Trade Center separately for the Presidential Award of Excellence in Engineering.
