What’s Cool In Steel?: December Issue of Modern Steel Features Barbara Walker Crossing Footbridge

What’s Cool In Steel? Modern Steel presents tons of fun projects showcasing the use of cool steel in the December Issue, including the Barbara Walker Pedestrian Bridge along Portland’s Wildwood Trail. The Barbara Walker Crossing Footbridge is a two time CODA Award Winner. The bridge, designed by local artist, Ed Carpenter, is 178’ long measured at the center of its curving deck. Its basic structure is a tri-chord truss of rusting and painted steel. Carpenter’s design evokes imagery of the sword ferns and vine maples lining the entire length of the Wildwood Trail. This project is a collaborative effort of the Portland Parks Foundation in partnership with Portland Parks & Recreation (PP&R), the Portland Bureau of Transportation (PBOT), and Metro. Albina Co., Inc. bent 3½” SCH80 A847 and 5″ SCH40 A847 all rolled to various radii, as well as 1″ SCH40 A53B, 1½” SCH40 A53B, 1½” SCH80 A53B all rolled to various radii.

It’s Here, It’s There, It’s Everywhere! Curved Steel at the Forefront of Construction at the University of Oregon

Two major construction projects are just wrapping up at the University of Oregon and curved steel is at the forefront of both projects!

Albina Co., Inc. bent 22″ OD x 1″ Wall Carbon Steel Pipe to a 105 foot center-line radius for a signature sky bridge that spans Franklin Boulevard and serves as a connector between campus and other U of O research facilities. The $225 million, 160,000-square-foot first phase opened in the Spring of 2020. Click on the link in my BIO to take a virtual tour of the building.

“The Front Runner in Steel Bending. We Tower Above the Rest” We were thrilled to be an integral part of reconstructing Hayward Field at the University of Oregon. Hayward Field is the world-class home to @OregonTF.

Albina created the curved steel diaphragm used to support the roof structure and provided various bent materials to help construct the landmark tower at the northeast corner of the facility. Designers wanted to create a structure that was open and airy, allowing spectators to enjoy great views and natural daylight, in an intimate environment.

For the roof, we rolled 600 lengths, varying from 28’-0” to 75’-6” long, of 14″ OD X .375″ / .500 WALL A500-18 GRADE B&C. That is 1,500,000# lot weight (750 tons) of rolled steel, 32 inbound trucks and 90 outbound trucks. The 14” OD material was laid over the top of the plate that we bent for this project. We bent 300 lengths, varying from 3’-0” to 37’-0” long, of PLATE 1½” THICK X 16¾” WIDE A572 GR. 50 and PLATE 1½” THICK X 10″ WIDE A572 GR. 50.

In addition to the iconic roof, the tower at Hayward (187 feet tall) creates a community landmark honoring the first 100 years of track and field at Oregon. We rolled 400 lengths, varying from 20’-0” to 60’-0” long, of Tube Steel 8″ X 4″ X .500″ WALL A500 GR B, 8-5/8″ OD X .625″ WALL A500C WHEELED, 8-5/8″ OD X .375″ WALL A500C WHEELED, 8-5/8″ OD X .250″ WALL A500C WHEELED, and Flat Bar 3/8″ X 4½” A36. That is 330,000# lot weight (165 tons) of rolled steel, 10 inbound trucks and 16 outbound trucks! Photo Credit: Oregon Track & Field.

Our work was extremely precise, and we had zero rejected parts by the fabricator, Fought & Co., Inc. When measuring the work points during fabrication, they never once had to heat up or adjust the bending. To make the erection process go smoothly, we marked every 3-4 feet on the centerline back of the pipe to assist in the layout process for the diagrid “fish-mouth” stubs, and up-stands for the roofing system.

The Awards just keep on coming! The National Steel Bridge Alliance has awarded the Williams Creek Shoup Bridge in Salem, Idaho a Merit Award in the Medium Span bridges category. Albina was happy to be a part of the project and provided 145,000# of bent structural steel and HSS including:

W18 X 234# A992
4 lengths x 100 ft- bent the easy way to a 179 ft radius
2 lengths x 75 ft- bent the easy way to a 179 ft radius

TS 8″ X 8″ X .375″ WALL A500 GR B
8 lengths x 53 ft: bent to a 304 ft radius.

Curved Steel at our Nation’s Schools & Universities

Boy how the tide has turned! No longer do I hear, “I don’t want to go to school today!” Instead I hear, “I can’t wait until we get to go back to school!” Kids across the country are gaining a new appreciation for how important it is to physically be able to enter their school buildings to learn. We have been very fortunate to be involved in a number of projects at schools across the nation including custom spiral and circular staircases, curved steel signs, curved steel artwork, curved steel canopies, and more!

Curved Steel Creates Crown Jewel Wagon Creek Bridge in Lake Siskiyou, CA.

Albina elliptically bent 50,000# of 14″ XH pipe, all material exposed, to extremely tight tolerances for the Wagon Creek Pedestrian Bridge in Mt. Shasta, California. The McConnell Foundation partnered with Siskiyou County by awarding a $600,000 grant for the Wagon Creek Bridge, and the bridge is considered the crown jewel of the Lake Siskiyou Trail.
