HSS Project of the Year Awards



The Steel Tube Institute (STI) is pleased to announce the inaugural HSS Project of the Year Awards, recognizing outstanding projects and the teams behind them. The awards celebrate notable achievements in design and construction involving hollow structural sections and provide industry recognition through the HSS Summit, STI communications, and industry outreach.

The program is open to projects across the United States, Canada, and Mexico that use North American-produced HSS. Entries may be submitted by members of the project team, including the structural engineer, architect, fabricator, erector, general contractor, owner, developer, or service center. Winners will be recognized at the HSS Summit 2026 in Huntsville, Alabama, where a representative of the project team will share the project with attendees as part of a featured project showcase.

The program recognizes six categories of excellence:


Best Commercial or Institutional Building

For projects including offices, schools, healthcare facilities, public buildings, mixed-use, hospitality, and residential.


Best Industrial or Infrastructure Project

For projects including data centers, manufacturing facilities, energy infrastructure, transportation, bridges, and utilities.


Best Sustainable HSS Project

For projects demonstrating documented sustainability leadership through embodied carbon performance, material efficiency, sourcing, and HSS-specific sustainability contributions.


Best Special Structure

For projects including stadiums, arenas, performance venues, convention centers, museums, landmark civic structures, monuments, and observation towers.


Best Alabama HSS Project (Judges’ Choice)

Drawn from all Alabama-located entries by the jury. Recognizes a notable HSS project in the host community of the 2026 HSS Summit.


Most Innovative Use of HSS (Judges’ Choice)

Drawn from all entries by the jury. Recognizes first-of-kind applications, novel use of HSS shapes, grades, or connections, boundary-pushing geometry, and projects that advance what’s possible with HSS.


Category rules: A project may be entered in only one type category (1 through 4). The Most Innovative Use of HSS and the Best Alabama HSS Project winners are selected by the jury from the full pool of entries; no separate submission is required.



Trophy

In addition to being recognized at the HSS Summit, each winning project team receives:

  • A custom HSS trophy
  • Certificates for each named team member
  • Complimentary HSS Summit registration and $1000 travel stipend for the designated presenter
  • A featured 10-15 minute presentation slot at the HSS Summit, including audience Q&A
  • Promotion through STI publications, website, and social media
  • Editorial pitches to industry publications

Project location. Project must be located in the United States, Canada, or Mexico.

Project status. Project must have been completed since January 1, 2024, or be substantially under construction at the time of entry. Substantially under construction means the structural system is sufficiently complete to demonstrate the design.

HSS source. All HSS used on the project must be manufactured in North America. 

HSS role. HSS must play a defining role on the project — as the primary structural system, a major architectural expression, a key engineered element, or a contribution critical to the project’s economics, schedule, or performance.

Eligible submitters. A member of the project team may submit an entry:

  • Structural engineer (engineer of record)
  • Architect
  • Fabricator or erector
  • Service center
  • General contractor or construction manager
  • Owner or developer

Multiple entries. A team may submit multiple projects, but each project may be entered in only one category.




Project narrative (500–750 words)

  • Contributions of the project team
  • Project description and design approach
  • Why HSS was selected and what role it plays
  • Key challenges and how they were resolved


HSS data summary

  • Size of building (gross floor area and number of stories)
  • Span or length (bridges, special structures, long-span buildings)
  • Total construction cost (in U.S. dollars)
  • Total HSS tonnage
  • ASTM grades used
  • Range of shapes and sizes


Project team credits

Owner or developer; architect; structural engineer of record; general contractor or construction manager; fabricator; erector; service center; HSS producer and tube mill location.


Photographs

Six to ten high-resolution photographs, including at least two in-construction images showing HSS in place. Photo rights and permissions must be cleared by the submitter.


Optional supporting materials

  • Drawings or details that illustrate HSS use
  • BIM screen captures
  • Sustainability documentation (EPDs, embodied carbon analysis, certifications) — required for Best Sustainable HSS Project entries


Designated presenter

Each entry must designate a primary presenter and a backup presenter. If selected as a winner, the designated presenter must attend the HSS Summit in person and present the project. See Attendance and Forfeit.



Each category is judged on the following criteria:


Best Commercial or Institutional Building

  • Architectural and engineering design — design vision and structural approach
  • Fabrication and construction quality — execution of the HSS work as shown in photos and described in the narrative
  • HSS’s contribution to the project — material selection, role in design intent, and what HSS uniquely enabled
  • Resolution of project challenges — challenges specific to the HSS portions of the project (design, fabrication, supply, erection), or broader project challenges overcome through HSS use
  • Team collaboration — notable cooperation between project participants (e.g., architect, engineer, fabricator, owner) that shaped project outcomes
  • Community impact — how the building serves its users and the surrounding community


Best Industrial or Infrastructure Project

  • Architectural and engineering design — design vision and structural approach
  • Fabrication and construction quality — execution of the HSS work as shown in photos and described in the narrative
  • HSS’s contribution to the project — span, capacity, environment, scale, or schedule advantages HSS provided
  • Resolution of project challenges — challenges specific to the HSS portions of the project (design, fabrication, supply, erection), or broader project challenges overcome through HSS use
  • Team collaboration — notable cooperation between project participants (e.g., architect, engineer, fabricator, owner) that shaped project outcomes

Entries are judged by a four-member jury representing perspectives of the HSS industry from any of the following entities:

  • Structural engineer
  • Architect
  • Fabricator or erector
  • HSS producer
  • Service center
  • Steel Tube Institute representative

The jury reviews all entries, scores them against category-specific criteria, and selects winners through deliberation. Jurors with a conflict of interest on a specific entry recuse from scoring that entry. The jury reserves the right to withhold an award in any category if no entry meets the standard.
