St. Louis, Missouri – Engineered Steel Products
- Complex and intricate roof system consisting of 350 unique cold-formed steel truss designs
- Minimal interruption to everyday campus life taking place literally a few feet away
- Required sequenced delivery of the trusses on a very specific schedule with pre-assembled sections of the roof delivered to the jobsite, ready to lift right into place with a production schedule squeezed from 16 weeks down to 12 weeks

College students face many challenges throughout their four, or five, or even eight years of higher education. They develop as adults, as individuals, as a community of students with similar goals during their time in school. Much can be said for the cold-formed steel
trusses that have become a regular part of new construction projects on Washington University’s Danforth campus in St Louis, Missouri. The latest project, the Eliot B Dormitory, sports a complex and intricate roof system consisting of 350 unique cold-formed
steel truss designs. Ultra-Span fabricator/partner Engineered Steel Products teamed with St. Charles, MO based panelizer and framing contractor Gateway Panels to deliver yet another successful cold-formed project to the St. Louis region.
Washington University, founded in 1853, has maintained an elite reputation as an institution of higher learning center in the fields of medicine, engineering, research, and law. As their website states, “To promote learning, the University encourages
independence, boldness, and originality of thought.” The same can be said for the buildings, both old and new, that dot the 169-acre Danforth campus. Several buildings on Wash U’s campus have even been listed on the National Register of Historic Places. Suffice to say, expectations are always high
when new structures are added to this historic and regal campus.
The Eliot B Dormitory (part of the University’s South 40 Redevelopment Project) is no exception and is a real show-piece in many respects. The “infill” structure is the fourth in a series of new dormitories that comprise the new, European streetscape-styled Danforth Student Center.
Due to the extremely tight job sight Gateway Panel, has had a year-long challenge of staging, delivering, hoisting and installing factory-built wall panels and roof trusses with minimal interruption to everyday campus life taking place literally a few feet away. Gateway attributes much of their success to
their steel truss supplier, Engineered Steel Products (ESP), based in Wright City, Missouri. Engineered Steel was required to sequence delivery of the trusses on a very specific schedule, so that Gateway could pre-assemble sections of the roof at their facility and
deliver to the jobsite, ready to lift right into place. According to Bruce Schierding, estimator and project manager with Gateway Panel, “This has to be a record. I’ve never seen a project go up so fast. We asked ESP to deliver certain roof sections on an extremely rigid schedule, and they came through without a
hitch—something previous truss suppliers have been unable to do.” Without the skill and reliability of Engineered Steel and cold-formed steel trusses there could have been significant challenges and delays. In fact, even with the production schedule squeezed from 16 weeks down to 12 weeks,
Engineered Steel met every demand.
Cold-formed steel was the best choice for this structure for many reasons. First, given the life expectancy of this structure, the materials used needed to stand the test of time. Using organic materials such as wood framing would immediately introduce temperance to the structural
framing. Cold-formed steel is an inorganic and stable product. It does not twist, warp, split and crack as it ages and transitions through climate cycles. In addition, cold-formed steel is 100% non-combustible. The first step in reducing the chance of fire damage in a structure is to remove the fuel (wood)
from the structural elements.
Cold-formed steel also contains a high recycled content. According to the Steel Recycling Institute (www.recycle-steel.org), 83.3% of new steel used comes from recycled steel. And, by taking full advantage of cold-formed steel and reducing the amount of heavy structural
steel, the weight of structures can often be significantly reduced.
All of these elements added together can greatly reduce the impact of new construction on our environment. This is reflected in the US Green Building Council’s (www.usgbc.org) Leadership in Energy and Environmental Design (LEED) program. The LEED rating
systems offers credits within its Materials and Resources sections, 4.1 and 4.2. Because material credits are awarded based on the percentage of the entire structure, increased use of cold-formed steel , with its high recycled content, will improve the likelihood
of a structure qualifying for these points. Architects Mackey Mitchell considered the positive contributions of cold-formed steel trusses and walls when selecting the framing materials.
The students moving into Eliot B will likely give little thought to the framing materials used to make up their home for the school year. However, Washington University and everyone involved in the construction of these beautiful new dormitories will
know that the materials used were chosen with great thought towards the sustainability of our planet.
